Legal Authorities Under the Controlled Substances Act to Combat the Opioid Crisis

Summary
According to the Centers for Disease Control and Prevention, the annual number of drug
overdose deaths involving prescription opioids (such as hydrocodone, oxycodone, and
methadone) and illicit opioids (such as heroin and nonpharmaceutical fentanyl) has more than
quadrupled since 1999. A November 2017 report issued by the President’s Commission on
Combating Drug Addiction and the Opioid Crisis also observed that “[t]he crisis in opioid
overdose deaths has reached epidemic proportions in the United States ... and currently exceeds
all other drug-related deaths or traffic fatalities.” How the current opioid epidemic happened, and
who may be responsible for fueling it, are complicated questions, though reports suggest that
several parties likely played contributing roles, including pharmaceutical manufacturers and
distributors, doctors, health insurance companies, rogue pharmacies, and drug dealers and addicts.
Many federal departments and agencies are involved in efforts to combat opioid abuse and
addiction, including a law enforcement agency within the U.S. Department of Justice, the Drug
Enforcement Administration (DEA), which is the focus of this report.
The primary federal law governing the manufacture, distribution, and use of prescription and
illicit opioids is the Controlled Substances Act (CSA), a statute that the DEA is principally
responsible for administering and enforcing. The CSA and DEA regulations promulgated
thereunder establish a framework through which the federal government regulates the
manufacture, distribution, importation, exportation, and use of certain substances which have the
potential for abuse or psychological or physical dependence, including opioids. Congress enacted
the CSA in 1970 to facilitate the availability of controlled substances for authorized medical,
scientific, research, and industrial purposes, while also preventing these substances from being
diverted out of legitimate channels for illegal purposes such as drug abuse and drug trafficking
activities. The CSA aims to protect the public’s health and safety from dangers posed by highly
addictive or dangerous controlled substances that are diverted into the illicit market, while also
ensuring that patients have access to pharmaceutical controlled substances for legitimate medical
purposes such as the treatment of pain.
This report describes the current federal legal regime governing opioids and other controlled
substances under the CSA and its implementing regulations, including (1) the classification of
various plants, drugs, and chemicals into one of five schedules based on the substance’s medical
use, potential for abuse, and safety or dependence liability; (2) who must register with the DEA in
order to receive authorization to handle the substances (such as drug manufacturers, wholesale
distributors, doctors, hospitals, pharmacies, and scientific researchers); (3) what obligations
registrants must satisfy in order to maintain a valid registration (such as keeping records of drug
inventories and transactions, submitting reports to the DEA, and providing security measures to
safeguard controlled substances); and (4) the DEA’s administrative, civil, and criminal authorities
for enforcing regulatory compliance with the CSA (such as suspending or revoking a registrant’s
legal authority to handle controlled substances if the DEA Administrator finds that the registrant
has “committed such acts as would render his registration ... inconsistent with the public
interest.”). The report then examines DEA initiatives and actions taken, pursuant to its legal
authorities under the CSA, which specifically target the abuse of opioids. The report concludes by
describing the legislative response to the opioid epidemic, including a summary of the
amendments to the CSA made by legislation enacted by the 115th Congress, the Substance UseDisorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities
Act (P.L. 115-271).

Legal Authorities Under the Controlled Substances Act to Combat the Opioid Crisis

he alarming rise in drug overdose deaths involving opioids over the past two decades1
has prompted the federal government to examine the causes of the public health crisis,
identify possible solutions to counteract the problem, and take actions to address the
crisis.2 The primary federal law governing the manufacture, distribution, and use of
prescription and illicit opioids is the Controlled Substances Act (CSA or the act),3 which
is administered and enforced by the Drug Enforcement Administration (DEA) in the U.S.
Department of Justice.4 The CSA provides the legal regime through which the federal government
(1) regulates and facilitates the lawful production, possession, and distribution5 of controlled
substances, including opioids; (2) prevents diversion6 of these substances from legitimate
purposes; and (3) penalizes unauthorized activities involving controlled substances.7

T

The regulatory framework under the CSA relies primarily on a registration system: the act
requires persons who handle controlled substances (such as drug manufacturers, wholesale
distributors, exporters, importers, health care professionals, hospitals, pharmacies, and scientific
researchers) to register with the DEA and comply with the terms and conditions of the
registration.8 Through this registration mechanism, the CSA creates a “closed system” of
distribution9 in which distribution may lawfully occur among registered handlers of controlled
substances, referred to under the act as “registrants.”10 To monitor the amount of particularly

4 While the CSA directs the Attorney General to enforce its provisions, the CSA also permits him to delegate such
responsibilities to any other officer or employee of the Department of Justice. 21 U.S.C. § 871(a). Pursuant to 28
C.F.R. § 0.100(b), the Attorney General has assigned much of the authority to implement and enforce the CSA to the
DEA Administrator. Accordingly, the term “DEA Administrator” will be used instead of the term “Attorney General”

5 The CSA broadly defines “distribution” to include virtually every transfer of possession. 21 U.S.C. § 802(11) (“The
term ‘distribute’ means to deliver (other than by administering or dispensing) a controlled substance or a listed

dangerous drugs that enters this distribution system,11 the CSA requires the DEA to establish a
quota system that restricts the total amount of certain controlled substances that may be annually
produced or manufactured.12
In order to minimize theft and diversion and to help the DEA monitor the flow of controlled
substances in the United States,13 the CSA and its implementing regulations subject registrants to
strict requirements regarding recordkeeping, maintaining the security of their controlled
substance inventories, and reporting certain information to the DEA.14 The “closed system” of
distribution, along with registrant compliance with the CSA’s regulatory requirements, helps to
ensure that a particular controlled substance is always accounted for by a DEA-registered entity,15
from its creation until it is dispensed16 to a patient17 or is destroyed.18 Note that patients are not
required to register with the DEA19 because the controlled substances in their possession “are no
longer part of the closed system of distribution and are no longer subject to DEA’s system of
corresponding accountability.”20
A registrant’s failure to meet its obligations under the CSA can result in a controlled substance
being diverted from legitimate channels. For example, “[d]istributors that blindly sell
pharmaceutical controlled substances to rogue pharmacies, and practitioners21 who issue
prescriptions without a legitimate medical purpose are diverting.”22 Such diversion can contribute
to drug abuse and addiction,23 which, in turn, increase the number of overdose deaths and

the packaging, labeling or compounding necessary to prepare the substance for such delivery.” 21 U.S.C. § 802 (10).

emergency room visits, two defining features of the current opioid epidemic.24 In addition, some
users who abuse prescription opioids may also start using cheaper and potentially easier to obtain
illicit opioids such as heroin, which provide similar euphoric effects.25
The CSA provides civil and criminal penalties for any unlawful26 manufacture, distribution,
importation, exportation, or possession of controlled substances.27 Such violations may include
(1) “regulatory” offenses committed by registrants who do not adhere to their responsibilities
under the CSA, thereby increasing the risk of diversion, and (2) illicit trafficking or possession
crimes that occur outside the “closed system” of authorized controlled substance distribution that
primarily involve nonregistrants.28
This report first provides a brief overview of the opioid epidemic and then describes in greater
detail the current federal legal regime governing opioids and other controlled substances under
the CSA and its implementing regulations. After that, the report examines DEA actions taken that
are specifically targeted at addressing opioid abuse and describes recently enacted laws amending
the CSA that impact the opioid regulatory system, including the Substance Use-Disorder
Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act (P.L.
115-271), enacted by the 115th Congress. The report concludes by discussing other legislative
options that the 116th Congress could consider to amend the CSA further to address the opioid
epidemic.

Brief Background on the Opioid Epidemic29

midst of an opioid overdose epidemic,” citing statistics that show the number of overdose deaths
involving opioids (including prescription opioids and illegal opioids such as heroin and

nonpharmaceutical fentanyl) has more than quadrupled since 1999, and on average 115
Americans now die each day from an opioid overdose.30 Former Attorney General Jeff Sessions
referred to the opioid epidemic as “the deadliest drug crisis in American history,”31 and President
Trump in October 2017 directed the Secretary of Health and Human Services to declare the crisis
a national public health emergency.32
The CSA defines the term “opioid” to mean “any drug or other substance having an addictionforming or addiction-sustaining liability similar to morphine or being capable of conversion into a
drug having such addiction-forming or addiction-sustaining liability.”33 Opioids can include
prescription pain relief drugs34 such as hydrocodone, oxycodone, codeine, morphine, and
fentanyl,35 as well as illegal drugs such as heroin and nonpharmaceutical (illicitly produced)
fentanyl.36 While doctors may prescribe U.S. Food and Drug Administration (FDA)-approved
opioids to patients to alleviate their pain, particularly following surgery or injury or for serious
health conditions such as cancer, some individuals may choose to abuse opioids for nonmedical
reasons (such as to experience feelings of relaxation or to get “high”) or by taking them in a
higher dosage or through different means than prescribed by their doctor (such as by snorting or
injecting the substance into a vein).37 The CDC has estimated that more than 40% of all opioid
overdose deaths in the United States in 2016 involved an FDA-approved prescription opioid.38
How the opioid epidemic occurred, and who is responsible for fueling it, are complicated
questions, though reports have suggested that many parties are likely involved to some extent,

companies,42 rogue pharmacies,43 and drug dealers and addicts.44 The National Institute on Drug
Abuse has described the origins of the opioid overdose crisis as follows:
In the late 1990s, pharmaceutical companies reassured the medical community that patients
would not become addicted to prescription opioid pain relievers, and healthcare providers
began to prescribe them at greater rates. This subsequently led to widespread diversion and
misuse of these medications before it became clear that these medications could indeed be
highly addictive.45

The President’s Commission on Combating Drug Addiction and the Opioid Crisis46 also cited
excessive prescribing of opioids since 1999 as a significant contributor to the proliferation of
opioids.47 The commission identified several other factors that have influenced the current opioid
crisis, including large scale production and distribution of addictive opioids, widespread
availability of illicit heroin and fentanyl, unethical physician prescribing practices and rogue
pharmacies that fill those illegitimate prescriptions, and a lack of education for medical
professionals and patients in prescribing and using opioids, respectively.48

Overview of the CSA
This section provides a general overview of the CSA’s closed system of distribution that regulates
opioids and other types of controlled substances, including the schedules in which the substances
are placed and the regulatory requirements and obligations that registrants must satisfy, such as
(1) registering with the DEA, (2) keeping accurate and complete records of controlled substance
inventories and transactions, (3) implementing security measures to safeguard controlled
substances from theft or diversion, (4) reporting certain information to the DEA (including
suspicious controlled substance orders), (5) meeting production quotas, and (6) prescribing
controlled substances only for legitimate medical purposes.

Scheduling of Controlled Substances
The CSA places various plants, drugs, and chemicals (such as narcotics, stimulants, depressants,
hallucinogens, and anabolic steroids) into one of five schedules based on the substance’s medical

use, potential for abuse, and safety or dependence liability.49 Opioids are types of narcotic drugs.50
To restrict access to chemicals used in the illicit manufacture of certain controlled substances, the
CSA also regulates specified “listed chemicals.”51 Furthermore, the CSA regulates controlled
substance “analogues,” which are substances that are not controlled but have chemical structures
substantially similar to those of controlled substances found in Schedule I or II.52
The order of the five schedules in which controlled substances are categorized reflects substances
that are progressively less dangerous and addictive.53 Schedule I contains substances, such as the
hallucinogen lysergic acid diethylamide (LSD) and the illicit opioid heroin, that have “a high
potential for abuse” with “no currently accepted medical use in treatment in the United States”
and that cannot safely be dispensed under a prescription.54 Schedule I substances may be used
only for bona fide, federal government-approved research studies.55 In contrast, schedules II, III,
IV, and V include substances that have recognized medical uses, such as prescription opioids like
oxycodone, codeine, and morphine, and may be manufactured, distributed, prescribed, dispensed,
and possessed in accordance with the CSA.56
The CSA provides an administrative mechanism for substances to be controlled (added to a
schedule);57 decontrolled (removed from the scheduling framework altogether); and rescheduled
or transferred from one schedule to another.58 Federal rulemaking proceedings to add, delete, or

Administrator must request from HHS a scientific and medical evaluation and recommendation as
to whether the drug or substance should be controlled or removed from control.60 The DEA
Administrator then must evaluate all of the relevant data and make a final determination as to
whether the drug or substance should be controlled or removed entirely from control.61
In making such determination, the DEA Administrator is required to consider statutory factors
such as the drug’s actual or relative potential for abuse; scientific evidence of its pharmacological

effect; the current state of scientific knowledge regarding the drug or substance; the risk to the
public health from the drug; and whether the substance is an immediate precursor62 of a substance
already controlled under the act.63 After the DEA Administrator makes this determination, he
must make specific findings concerning the drug or substance that dictate the schedule in which
the drug or substance will be placed.64
For example, in 2009, the DEA requested from HHS an evaluation and recommendation
concerning whether to reschedule hydrocodone combination products (HCPs) such as Vicodin®
from Schedule III to Schedule II.65 After evaluating the scientific and medical evidence showing,
among other things, significant diversion of HCPs and the health and safety risks created by
people who abuse HCPs, HHS then recommended to DEA that HCPs should be reclassified to the
more restrictive Schedule II,66 In 2014, DEA published a final rule that administratively
reschedules HCPs from Schedule III to Schedule II, thereby subjecting anyone who
manufactures, distributes, or dispenses HCPs to the more stringent regulatory requirements (and
administrative, civil, and criminal sanctions) that are applicable to Schedule II controlled
substances.67
Congress may also change the scheduling status of a drug or substance at any time through
enactment of legislation. For example, Congress passed the Synthetic Drug Abuse Prevention Act
of 201268 that permanently added two synthetic cathinones (central nervous system stimulants) to
Schedule I of the CSA, along with cannabimimetic substances (commonly referred to as synthetic
marijuana).69

Emergency or Temporary Scheduling
The CSA authorizes the DEA Administrator to place a drug or substance that is not currently
controlled, on a temporary basis, into Schedule I when he finds such scheduling “necessary to
avoid an imminent hazard to the public safety.”70 The DEA Administrator may not issue a
temporary scheduling order until 30 days after he notifies both the public and the HHS Secretary
of his intent to issue the temporary scheduling order and of his justification for issuing the order.71
Furthermore, the DEA Administrator must consider the HHS Secretary’s comments regarding the

62 The CSA defines an “immediate precursor” to mean a substance that (1) the DEA Administrator has determined to

be and has “designated as being the principal compound used, or produced primarily for use, in the manufacture of a
controlled substance;” (2) “is an immediate chemical intermediary used or likely to be used in the manufacture of such
controlled substance;” and (3) is necessary to control “to prevent, curtail, or limit the manufacture of such controlled
substance.” 21 U.S.C. § 802 (definition of “immediate precursor”).

temporary order.72 A drug or substance may be temporarily scheduled for two years and possibly
longer—up to an additional year—if formal scheduling procedures have been initiated.73 As
discussed below in the report, DEA has exercised its emergency scheduling authority eight times
to control seventeen substances structurally related to the opioid fentanyl by placing them
temporarily in Schedule I.74

Scheduling in Order to Satisfy International Treaty Obligations
Treaty obligations may require the DEA Administrator to control or reschedule a substance if
existing controls under federal law are less stringent than those required by a treaty. 75 The United
States is a party to three United Nations drug control treaties that impose certain international
obligations relating to the manufacture, distribution, use, and possession of controlled substances,
including the Single Convention on Narcotic Drugs of 1961,76 which was designed to establish
effective control over international and domestic traffic in narcotics, coca leaf, cocaine, and
marijuana.77 The United States is also party to the Convention on Psychotropic Substances of
1971,78 which was designed to establish similar control over stimulants, depressants, and
hallucinogens. Finally, the United States is a party to the 1988 Convention against Illicit Traffic in
Narcotic Drugs and Psychotropic Substances,79 which requires parties, among other things, to
control precursor chemicals used in the illicit manufacture of drugs and to take measures to
combat money laundering crimes related to drug trafficking.

Who Must Register with the DEA?
The CSA requires any person who seeks to manufacture, distribute, dispense, or conduct research
involving any controlled substance (such as drug manufacturers, wholesale distributors,
physicians, hospitals, pharmacies, and scientific researchers) to obtain a registration from the

77 For example, in response to petitions from the public to transfer marijuana from Schedule I of the CSA to Schedule
II, the DEA explained how the United States obligations under the international drug control treaties constrain the
agency’s choice of schedules with respect to marijuana:
The DEA Administrator is obligated under [21 U.S.C.] section 811(d) to control marijuana in the
schedule that he deems most appropriate to carry out the U.S. obligations under the Single
Convention. It has been established in prior marijuana rescheduling proceedings that placement of
marijuana in either schedule I or schedule II of the CSA is ‘‘necessary as well as sufficient to
satisfy our international obligations’’ under the Single Convention. NORML v. DEA, 559 F.2d
735, 751 (D.C. Cir. 1977). As the United States Court of Appeals for the DC Circuit has stated,
‘‘several requirements imposed by the Single Convention would not be met if cannabis and
cannabis resin were placed in CSA schedule III, IV, or V.’’ Id. Therefore, in accordance with
section 811(d)(1), DEA must place marijuana in either schedule I or schedule II.

DEA,80 unless they are exempt.81 Registrations specify the extent to which the DEA has
authorized registrants to manufacture, possess, distribute, or dispense controlled substances.82 The
DEA currently regulates more than 1.73 million registrants.83 The CSA authorizes the DEA
Administrator to charge reasonable fees relating to the registration and control of the
manufacturing, distribution, and dispensing of controlled substances under the act.84
The CSA directs the DEA Administrator to register an applicant if the Administrator determines
that, among other things, it would be consistent with the “public interest” to do so.85 The CSA
provides several criteria that the DEA Administrator must consider in assessing whether
registering an applicant is consistent with the “public interest.” The criteria differ depending on
the substance involved and whether the applicant is a manufacturer, distributor, or practitioner,
but include general factors such as those relating to public health and safety and compliance with
state and local laws.86 Manufacturers and distributors of controlled substances must obtain a
registration from the DEA annually, and those who dispense controlled substances must obtain
registrations that may not be issued for less than one year or more than three years.87 The
registration of an individual terminates when the person dies, ceases legal existence, or
discontinues business or professional practice.88 A registration cannot be transferred to someone
else unless the Administrator provides his express, written consent for such a transfer to occur.89
In some instances, applicants must apply for several separate registrations in order to comply with
the CSA. For example, separate registrations are generally required for each principal place of
business or professional practice where controlled substances are manufactured, distributed,

imported, exported, or dispensed.90 For example, a physician who is regularly engaged in
dispensing controlled substances at one location must register to dispense controlled substances at
other locations if he chooses to dispense controlled substances at these other locations.91

Exceptions to the Registration Requirement
The CSA allows for exceptions and also exempts certain individuals from some or all of its
regulatory requirements. For example, individuals exempted from registration requirements
include, among others, officers or employees of the DEA, officers of the U.S. Customs Service,
offers or employees of the FDA, and any other federal officers who are authorized to possess,
import, or export controlled substances in the course of their official duties.92 Officers or
employees of any state, or political subdivision of a state, who are engaged in enforcement of
state or local laws relating to controlled substances, are also exempt from registering with the
DEA.93 A person who has lawfully obtained, and who possesses, a controlled substance for his
own legitimate medical use (a patient) is also not required to register.94
In addition, only those actually engaged in activities relating to manufacturing, distributing, and
dispensing controlled substances are required to obtain registration, but related or affiliated
persons who are not engaged in such activities are not required to register. For example, a
stockholder or parent corporation of a corporation that manufactures controlled substances is not
required to obtain registration, nor are employees of a registered manufacturer, distributor, or
dispenser.95
The DEA Administrator may, by regulation, waive the registration requirement for certain
manufacturers, distributors, or dispensers, if he finds it consistent with the public health and
safety.96

Regulatory Obligations of Registrants Under the CSA
The CSA imposes specific obligations on registrants in an effort to reduce the potential diversion
of controlled substances out of legitimate distribution channels.97 In particular, the CSA imposes
legal duties relating to (1) recordkeeping by registrants, (2) measures ensuring the secure storage
of controlled substances handled by registrants, (3) reporting certain information to the DEA, (4)

Legal Authorities Under the Controlled Substances Act to Combat the Opioid Crisis

prescribing and dispensing controlled substance medications by registered doctors and
pharmacists, and (5) the quantity of controlled substance that may be produced by manufacturers.

Recordkeeping
All registrants are required by the CSA to maintain complete and accurate inventories and records
of all regulated transactions involving controlled substances and listed chemicals.98 For example,
a registrant must make a complete and accurate record of each substance manufactured, received,
sold, delivered, or otherwise disposed of by the registrant.99 Furthermore, inventories must be
available for inspection by the DEA for at least two years.100 The CSA declares that it is unlawful
for any person to “refuse or negligently fail to make, keep, or furnish any record, report,
notification, declaration, order or order form, statement, invoice, or information required” by the
CSA.101 It is also unlawful for any person knowingly or intentionally “to furnish false or
fraudulent material information in, or omit any material information from, any application, report,
record, or other document required to be made, kept, or filed” under the CSA.102
In certain circumstances, the CSA recordkeeping provisions do not apply. For example, the
provisions do not apply to the prescribing or administering of a controlled substance listed in
Schedules II-V by practitioners acting in the lawful course of their professional practice unless
such substance is prescribed or administered in the course of maintenance or detoxification
treatment of an individual.103 As discussed below, this has implications for the drugs typically
used in the treatment of opioid addiction, two of which are controlled substances, while the other
is not.

Security Measures
For the purposes of ensuring the secure storage and distribution of controlled substances and
listed chemicals, all applicants for DEA registration and registrants must generally “provide
effective controls and procedures to guard against theft and diversion of controlled substances.”104
DEA regulations also detail specific security requirements for different types of applicants and
registrants. For example, nonpractitioners (i.e., manufacturers, distributors, and narcotic treatment
programs) are required to store Schedule I and II substances in electronically monitored safes,
steel cabinets, or vaults that meet or exceed certain specifications.105 Licensed practitioners must
store controlled substances in a “securely locked, substantially constructed cabinet”106 and must
notify the DEA of the theft or significant loss of any controlled substances within one business

day of discovering such loss or theft.107 Furthermore, all practitioners are prohibited from hiring
employees who have been convicted of a drug-related felony or who have had a DEA registration
denied or revoked.108 DEA regulations recommend that nonpractitioners carefully screen
individuals before hiring them as employees, to ensure that job applicants do not have convictions
for crimes or have not engaged in unauthorized use of controlled substances.109

Reporting
The CSA requires manufacturers, distributors, and pharmacies to report periodically to the DEA
every sale, delivery, disposal, or dispensing of any controlled substance.110 Registered pharmacies
that are authorized to dispense controlled substances by means of the internet must also report to
the DEA Administrator the type and total quantity of each controlled substance that the pharmacy
has dispensed each month via the internet.111 In addition, the CSA requires manufacturers,
distributors, and dispensers of controlled substances (1) to design and operate a system (that is
compliant with applicable federal and state privacy laws) that will alert the registrant of
suspicious orders of controlled substances, and (2) upon discovering a suspicious order or series
of orders, to inform the DEA Administrator and the Special Agent in Charge of the DEA Field
Division Office.112 The CSA defines “suspicious orders” as those that may include, but are not
limited to, orders of unusual size, orders deviating substantially from a normal pattern, and orders
of unusual frequency.113
Manufacturers and distributors of Schedule I and II drugs must file reports114 with the DEA
through the Automated Reports and Consolidated Orders System (ARCOS),115 which is an
automated drug reporting system that allows the agency to “monitor[] the flow of DEA controlled
substances from their point of manufacture through commercial distribution channels to point of
sale or distribution at the dispensing/retail level.... ”116 Certain narcotics listed in Schedules III
and IV are also covered by the ARCOS reporting requirements.117 According to the DEA, U.S.
attorneys and DEA investigators may use ARCOS controlled substances transaction information
“to strengthen criminal cases in the courts.”118

Quotas
The CSA includes a production quota system that requires the DEA to establish the total amount
of each basic class of Schedule I and II controlled substances and certain listed chemicals119 that
may be manufactured in a given calendar year, in order “to provide for the estimated medical,
scientific, research, and industrial needs of the United States, for lawful export requirements, and
for the establishment and maintenance of reserve stocks.”120 The DEA establishes this quota,
referred to as the aggregate production quota (APQ), for approximately 200 Schedule I and II
controlled substances.121 The DEA assigns individual production quotas to controlled substance
manufacturers that prevent the APQ from being exceeded.122 The CSA allows a registrant to apply
for an increase in his individual manufacturing quota if it is necessary “to meet his estimated
disposal, inventory, and other requirements during the remainder of that year.”123
By regulation, the DEA Administrator must consider the following factors in making his APQ
determinations: (1) the total disposal of the controlled substance during the current year and two
preceding years; (2) trends in the national rate of new disposal of the controlled substance; (3)
total inventories (actual or estimated) of “the class and all substances manufactured from the class
[of controlled substances listed in Schedule I or II];” (4) projected demand for a particular
controlled substance; (5) the extent of any diversion of the controlled substance in the class; (6)
relevant information obtained from the Department of Health and Human Services and from the
states; and (7) other relevant factors affecting the use of controlled substances including changes
in the currently accepted medical use of a controlled substance, the economic and physical
availability of the raw materials necessary to produce a controlled substance, and recent
unforeseen emergencies (i.e., natural disasters).124
A registrant may not manufacture a Schedule I or II controlled substance or a specified listed
chemical that is (1) not expressly authorized by his registration and by the individual quota
assigned to him by the DEA, or (2) in excess of that quota.125

Prescription Requirements
The CSA provides specific requirements that practitioners and pharmacists must observe when
prescribing and dispensing controlled substances in Schedules II-V to patients for legitimate
medical purposes.126 As noted, controlled substances classified as Schedule I drugs are deemed to
have no accepted medical purpose in the United States, and thus they may only be used for
research,127 and may not be prescribed or dispensed to patients.128 DEA regulations hold both the

prescribing practitioner and the pharmacist who fills the prescription responsible for ensuring that
the controlled substance is properly prescribed and dispensed.129 A DEA manual prepared for
pharmacists to help them understand their obligations under the CSA explains that
A pharmacist is required to exercise sound professional judgment when making a
determination about the legitimacy of a controlled substance prescription. Such a
determination is made before the prescription is dispensed. The law does not require a
pharmacist to dispense a prescription of doubtful, questionable, or suspicious origin. To
the contrary, the pharmacist who deliberately ignores a questionable prescription when
there is reason to believe it was not issued for a legitimate medical purpose may be
prosecuted along with the issuing practitioner, for knowingly and intentionally distributing
controlled substances.130

Practitioners
Under the CSA, only licensed medical practitioners are authorized to prescribe controlled
substances listed in Schedules II-V to patients.131 A prescription for a controlled substance must
be “issued for a legitimate medical purpose by an individual practitioner acting in the usual
course of his professional practice.”132 A pharmacist may not dispense to a patient a Schedule II
controlled substance without a written prescription133 from a practitioner, except in certain cases
where the practitioner administers the controlled substance directly to the patient.134 However, in
the case of an “emergency situation,”135 a practitioner may orally authorize a pharmacist to fill a
prescription for a Schedule II controlled substance.136 Controlled substances in Schedules III-V
may be dispensed by a pharmacy pursuant to either a written or oral prescription, including a
facsimile of a written prescription.137 These substances may also be administered or dispensed
directly by the practitioner in the course of his professional practice without a prescription.138

assuming that the electronic prescription complies with detailed requirements set forth in the
applicable federal regulations.139

Pharmacists
Pharmacists may partially fill a prescription for Schedule II substances under certain
circumstances, such as pursuant to a request by the patient or the practitioner who wrote the
prescription.140 Pharmacists are prohibited from refilling prescriptions for Schedule II
substances.141 A pharmacist may fill or refill prescriptions for controlled substances in Schedules
III and IV, however, up to five times within six months after the date on which the prescription
was issued, unless the prescribing practitioner authorizes a renewal of the prescription.142 A
pharmacy may process electronic prescriptions for controlled substances if the pharmacy uses a
computer application that complies with several requirements specified in the applicable federal
regulations.143 A controlled substance that is a prescription drug may not be delivered, distributed,
or dispensed by means of the internet without a “valid prescription,”144 which the CSA defines as
a prescription that is issued for a legitimate medical purpose in the usual course of professional
practice by a practitioner who has conducted at least one medical evaluation of the patient in the
physical presence of the practitioner.145

What Are the Potential Consequences for Violating the CSA?
The CSA contains a variety of criminal sanctions for illicit possession, manufacture, and
distribution of controlled substances that occurs outside the closed system of distribution.146 For
example, the CSA outlaws “simple possession” of a controlled substance147 (referring to a person
knowingly or intentionally possessing a controlled substance) “unless such substance was
obtained directly, or pursuant to” a valid prescription issued by a medical practitioner, “or except
as otherwise authorized by” the CSA.148 The CSA also prohibits any person from knowingly or

142 Id. 829(b); 21 C.F.R. § 1306.22(a).
143 21 C.F.R. § 1311.205. The requirements include providing the pharmacy with the ability to sign digitally and
archive the controlled substance prescriptions and allowing the pharmacy to limit employee access for annotating,
altering, or deleting controlled substance prescription information. Id.
144 21 U.S.C. § 829(e).
145 Id.
146 Many of these criminal penalties appear in 21 U.S.C. § 841, which provides that “[e]xcept as authorized by” the
CSA, “it shall be unlawful for any person knowingly or intentionally” to commit the unlawful acts specified in §
841(a).
147
Generally speaking, the CSA’s simple possession statute is used to prosecute those found in possession of quantities
of controlled substances that are consistent with “personal use” amounts and when the evidence suggests that the
possession is for the purpose of personal use, rather than for resale or distribution. See United States v. Mack, 343 F.3d
929, 934 (8th Cir. 2003) (“We frequently rely on drug quantity as evidence of defendants’ intended purpose for
disposition of their drugs, i.e. personal use or sale.”).
148 21 U.S.C. § 844(a). With the exception of simple possession of flunitrazepam (commonly used as a “date rape”
drug), a first-time simple possession offense is a federal misdemeanor punishable by a maximum term of imprisonment
of 1 year. (Simple possession of flunitrazepam is punishable by a term of imprisonment of up to 3 years). Anyone who
commits a federal simple possession offense after a single prior conviction under federal or state drug laws is subject to
a mandatory minimum sentence of 15 days and up to 2 years in prison; those who have multiple prior drug offense

intentionally acquiring or obtaining possession of a controlled substance by misrepresentation,
fraud, forgery, deception, or subterfuge.149 It is unlawful for any person knowingly or
intentionally to “traffic” in controlled substances; illegal drug trafficking150 generally refers to
distributing or dispensing, or to possessing with intent to distribute or dispense, a controlled
substance, unless the particular activity is authorized by law.151 The CSA’s criminal penalties for
trafficking in controlled substances vary depending on whether the individual is a first-time
offender or a repeat offender, the type of substance involved, and the quantity of the type of
substance involved.152 For example, a federal drug trafficking offense committed by a first-time
offender involving a Schedule II substance such as codeine is punishable by a term of
imprisonment of up to 20 years and a fine of up to $1,000,000.153 For a second offense, the fine
increases to $2,000,000 and the maximum imprisonment term increases to 30 years.154
The focus of this report, however, is on the CSA penalty provisions specifically applicable to
persons registered with the DEA. The CSA sets forth certain “regulatory” offenses involving
listed chemicals,155 failure to comply with CSA requirements and obligations that registrants must
satisfy as a condition of registration,156 and other prohibited acts by registrants who manufacture,
distribute and dispense controlled substances.157
For example, a registrant authorized to distribute or dispense any controlled substance is
prohibited from distributing, dispensing, or manufacturing controlled substances in a manner that
is not authorized by his particular registration.158 As noted above, registrants may not refuse or
negligently fail to maintain accurate records of controlled substances, and may not refuse to

convictions face a mandatory minimum sentence of 90 days and up to 3 years in prison. Id.
149 Id. § 843(a)(3). A violation of this may result in a term of imprisonment of not more than four years or a fine of up
to $250,000, or both; second offenses involving this section increase the maximum imprisonment term to eight years.
Id. § 843(d)(1).
150 The CSA and its implementing regulations do not define the term “traffic” or “trafficking,” though the CSA does
expressly use the term “drug traffickers” in one provision, 21 U.S.C. § 862, and the term “traffic” in three other
sections, id. §§ 801, 801a, 873. The U.S. Sentencing Guidelines, which greatly influence the sentences that federal
judges impose on those convicted of federal crimes, defines a “drug trafficking offense” as “an offense under federal,
state, or local law that prohibits the manufacture, import, export, distribution, or dispensing of, or offer to sell a
controlled substance (or a counterfeit substance) or the possession of a controlled substance (or a counterfeit substance)
with intent to manufacture, import, export, distribute, or dispense.” U.S.S.G. § 2L1.2, Application Notes (2). For more

.
153 21 U.S.C. § 841(b)(1)(C). These penalties apply only if no death or serious bodily injury results from the use of such
unlawfully trafficked substance. If such health consequences occur, however, the authorized penalty is a mandatory
minimum sentence of 20 years and up to life in prison. Id.

158 Id. § 842(a)(2). As noted above, registrations specify the extent to which the DEA has authorized registrants to
manufacture, possess, distribute, or dispense controlled substances. Thus, for example, a pharmacist is authorized to
dispense controlled substances to individuals only pursuant to a valid prescription issued by a DEA-licensed
practitioner and may not dispense such substances without that prescription.

Congressional Research Service

furnish such records when required to do so by law enforcement officials159 (such as the
requirement that registrants report to the DEA any “suspicious orders of controlled
substances).”160 It is unlawful for registrants to prohibit law enforcement officials from entering
their premises for inspections authorized by the CSA.161 Similarly, practitioners and pharmacists
may not dispense or distribute a controlled substance drug in violation of the CSA’s statutory
prescription requirements.162
The CSA also proscribes certain acts committed by a registrant related to the manufacture and
distribution of controlled substances and listed chemicals. Registrants may not knowingly or
intentionally (1) distribute Schedule I and II substances without a valid order form;163 (2) use an
invalid registration number during the course of handling or acquiring controlled substances;164
(3) furnish false or fraudulent material information in a record or report required by the act;165 or
(4) present false or fraudulent identification when receiving a listed chemical.166 Registrants who
violate the aforementioned provisions may be subject to injunctive or declarative actions filed by
the Attorney General in federal district court in addition to the general penalties described in the
next paragraph.167 Manufacturers may also not produce Schedule I or II controlled substances or
specified listed chemicals that are not expressly authorized by their registration or in excess of the
individual production quotas assigned to them by the DEA.168
Registrants who fail to adhere to the CSA’s regulatory requirements or who engage in certain
prohibited acts may face administrative consequences, civil and criminal fines, and even the
possibility of imprisonment.169 The CSA provides that violations of its regulatory requirements
generally do not constitute a crime and that “imposition of a civil penalty ... shall not give rise to
any disability or legal disadvantage based on conviction for a criminal offense,”170 unless the
violation was committed knowingly, in which case the CSA authorizes imprisonment of up to one
or two years.171

State Regulation of Controlled Substances
In addition to federal oversight of controlled substances and registrants who handle them,
Congress has permitted state governments to regulate the use of controlled substances under their
own state controlled substances acts.172 The U.S. Supreme Court has stated that the CSA

“manifests no intent to regulate the practice of medicine generally” and has observed that its
“structure and operation ... presume and rely upon a functioning medical profession regulated
under the States’ police powers”173 that may be used “to protect the health, safety and welfare of
their citizens.”174 For example, all states have prescription drug monitoring programs (PDMPs)
that maintain statewide electronic databases of prescription controlled substances dispensed to
patients within their jurisdictions; such information may be used by those working in law
enforcement, professional licensing bodies, and health care to identify patterns of prescribing,
dispensing, or receiving controlled substances that could indicate abuse or diversion.175 States
may also subject certain controlled substance medications to stricter regulation than the CSA
requires. For example, the states of Oregon176 and Mississippi177 have passed laws that require
anyone to obtain a prescription for drugs containing pseudoephedrine (a nasal decongestant
commonly found in over-the-counter cold, allergy, and sinus medications), which is an important
ingredient in producing illicit methamphetamine,178 whereas the substance is regulated as a listed
chemical under the CSA that does not require a prescription to dispense.179
The operation of several provisions of the CSA depends on state laws and state regulatory bodies.
For example, if a physician wants to obtain a DEA registration to dispense controlled substance
medications, he must first be “authorized to dispense ... controlled substances under the laws of
the State in which he practices.”180 In addition, the DEA Administrator must be satisfied that
issuing the applicant a registration would be “[]consistent with the public interest,” a
determination that requires the DEA Administrator to consider several statutory factors, including
the “recommendation of the appropriate State licensing board or professional disciplinary
authority”; the applicant’s previous convictions for federal or state controlled substances
offenses; and the applicant’s “[c]ompliance with applicable State, Federal, or local laws relating
to controlled substances.”181 Despite the latitude that Congress has given to states to regulate
controlled substances, however, the CSA nevertheless generally preempts, or overrides, state laws
regarding controlled substances when “there is a positive conflict between” a CSA provision and
“that State law so that the two cannot consistently stand together.”182

violations of the CSA involving controlled pharmaceuticals183 while also “ensuring an adequate

and uninterrupted supply for legitimate medical, commercial, and scientific needs.”184 The Office
of Diversion Control also manages the regulation of registrants, promulgates regulations
concerning the handling of controlled substances, and establishes controlled substance production
quotas.185 The Assistant Attorney General for the DOJ’s Criminal Division conducts, handles, or
supervises all criminal and civil litigation to enforce the CSA.186 Several federal courts have held
that the CSA does not contain an express or implied cause of action provision under which private
parties or state,187 local, or tribal governments may sue registrants for noncompliance with their
CSA obligations,188 noting instead that the CSA expressly authorizes only the Attorney General
and the U.S. Department of Justice to enforce federal controlled substances laws.189

Investigations
The DEA can conduct a variety of investigations to monitor and ensure registrant compliance
with the CSA and its implementing regulations.190 As mentioned earlier, registrants may not
prevent law enforcement officials from entering their premises for any inspections authorized by
the CSA.191 The three types of investigations that the DEA may undertake can be classified as
regulatory, complaint, and criminal.192 Regulatory investigations can include scheduled
inspections of registrants, usually every two, three, or five years, although such inspections
generally are directed at manufacturers, wholesale distributors, and importers/exporters rather
than physicians and pharmacies (who receive such oversight from state regulators).193 The DEA

may initiate complaint investigations after it has received a tip about potential diversion by the
registrant or if the DEA has identified any unusual drug transactions involving the registrant.194
Finally, the DEA may conduct criminal investigations regarding potential criminal activities
involving diversion of controlled substances.195 Criminal investigations can be directed at either
registrants or nonregistrants, such as an individual suspected of stealing drugs from a pharmacy
or one who is trafficking in unlawfully obtained controlled substances.196 Following an
investigation of a registrant that reveals violations of the CSA and its implementing regulations,
the DEA can take certain enforcement actions, as discussed in the following section.

Enforcement Actions
The DEA has discretion197 to initiate enforcement actions to seek a variety of administrative,
civil, and criminal penalties against a registrant who is not in compliance with the CSA,
depending on the severity of the offense and taking into consideration factors such as whether the
registrant has previously violated a CSA regulatory requirement.198 This section focuses on the
administrative actions that the DEA may take against a registrant or an applicant for registration.

Letter of Admonition or Informal Hearing
A noncompliant registrant could face several types of corrective actions. For example, the DEA
can issue a warning letter referred to as a Letter of Admonition (LOA) to a registrant suspected of
conduct inconsistent with his obligations under the CSA and its implementing regulations.199 The
DEA can also hold an Informal Hearing (IH) concerning the registrant; either administrative
action “provide[s] registrants an opportunity to recognize and acknowledge their infractions, and
immediately correct them.”200

Administrative Proceedings to Deny, Revoke, or Suspend a Registration
The DEA Administrator has the authority to deny, revoke, or suspend registrations under certain
circumstances.201 However, before the DEA Administrator can take such an action, the agency
must generally provide the applicant or registrant with notice and an opportunity to demonstrate
why the registration should not be denied, revoked, or suspended.202 This notice is referred to as

an Order to Show Cause or OTSC.203 Such an order provides the basis for the proposed denial,
revocation, or suspension (including an identification of the laws or regulations that the applicant
or registrant is alleged to have violated)204 and also notifies the applicant or registrant of the
opportunity to submit to the DEA a corrective action plan (CAP).205 The OTSC instructs the
applicant or registrant to appear at a hearing before a DEA Administrative Law Judge (ALJ) that
must be conducted in accordance with the Administrative Procedure Act (APA).206 If the
registrant submits a CAP, the DEA Administrator is required to determine “whether denial,
revocation, or suspension proceedings should be discontinued.”207
After examining the evidence and arguments submitted by the parties, the ALJ is required to
submit a report to the DEA Administrator that explains his recommended ruling, findings of fact,
conclusions of law, and decision regarding the proposed denial, revocation, or suspension.208 “As
soon as practicable after” receiving the ALJ’s record and report,209 the DEA Administrator is
required to publish in the Federal Register a final order in the proceeding that adopts, modifies,
or rejects the ALJ’s recommended decision.210 The CSA also provides that if the DEA
Administrator suspends or revokes an existing registration, all controlled substances owned or
possessed by the registrant may “be placed under seal ... until the time for taking an appeal has

Immediate Suspension Orders
Simultaneously with the institution of administrative proceedings to revoke or suspend a
registration (or at any time after the DEA Administrator issues an OTSC notifying the registrant
that the DEA is taking action to revoke or suspend a registration),213 the DEA Administrator may
exercise emergency power to suspend immediately any existing registration for a limited time
period in order to avoid “an imminent danger to the public health or safety.”214 This agency action
is often referred to as an “immediate suspension order” (ISO), and does not require the DEA to
provide the registrant with prior notice or a formal hearing.215 The CSA specifies that the
suspension “shall continue in effect until the conclusion of [the] proceedings [to revoke or
suspend the registration on a final basis], including judicial review thereof, unless sooner
withdrawn by the Attorney General or dissolved by a court of competent jurisdiction.”216
Prior to the enactment into law of the Ensuring Patient Access and Effective Drug Enforcement
Act (EPAEDEA) of 2016,217 the CSA did not expressly define the phrase “imminent danger to the
public health or safety,” and, as a result, courts held that the DEA Administrator possessed
“significant discretion” to determine when the continued registration of a registrant constituted
such a threat.218 As an example of the latitude that courts afforded the DEA Administrator’s

‘precise guidelines’ that restrict the meaning of ‘imminent danger,’ the Act vests the Administrator with discretion to
make such a determination. In addition, the statute contemplates that an ISO will be issued in emergency
circumstances, prior to an administrative hearing or the development of a formal evidentiary record. Thus, given the
degree of discretion vested with the Administrator as well as the summary and urgent nature of an ISO, the Court’s
review ‘must be correspondingly relaxed.’”) (citation omitted). However, in at least two cases prior to enactment of the
2016 EPAEDEA, courts did reject DEA’s ISO determination that the alleged violations met the “imminent danger”
standard. See, e.g., Bates Drug Stores v. Holder, Case No. CV–11–0167–EFS, 2011 WL 1750066 *3 (E.D. Wash.
2011) (“[T]he Court has serious doubts that the alleged violations ... pose an imminent danger to public health and
safety. There is nothing in the record indicating that any Bates patient has been harmed or injured by the alleged
violations. Nor is there any evidence that any controlled substance was dispensed to an improper individual, for an
improper purpose, or in an improper dosage.... On this record, the Court finds that serious questions exist as to whether
the Suspension Order supports a finding that Bates’ practices posed an imminent danger to the public health and
safety.”); see also Norman Bridge Drug Co. v. Banner, 529 F.2d 822, 826, 829 (5 th Cir. 1976) (holding that the lower
court’s decision that there was no imminent danger to the public health and safety was not clearly erroneous due to,
among other things, the DEA being aware of the facts alleged to justify issuance of the ISO for seven months prior to
issuing the order).

imminent danger finding, a federal district court permitted the DEA to rely on pharmacy
controlled substances sales data from 2008 to support an ISO issued in early 2012.219
The EPAEDEA amended the CSA to provide, for the first time, a statutory definition of the
phrase “imminent danger to the public health or safety,” which limits the DEA Administrator’s
discretion to issue an ISO and creates new evidentiary requirements that he must satisfy before
issuing such an order.220 Under the EPAEDEA, the DEA’s authority to issue an ISO depends on
the agency’s ability to prove two things: (1) “an immediate threat that death, serious bodily harm,
or abuse of a controlled substance will occur” due to the failure of the registrant to comply with
the CSA’s requirements, including those obligating the registrant “to maintain effective controls
against diversion,”221 and (2) the probability that such a threat will occur without an immediate
suspension of a registration, which the statute requires to be a “substantial likelihood.”222 Some
have suggested that the legislative changes made by the EPAEDEA considerably weaken the
power of the DEA to issue an ISO against a distributor or manufacturer,223 although others have
argued that the addition of a statutory definition of “imminent danger to the public health or
safety” was necessary in order to prevent “a completely subjective determination made solely by
the DEA” that “summarily eliminate[s] the registrant’s ability to handle controlled substances
before any due process hearing.”224
In response to the ISO, a registrant could seek immediate judicial review of the ISO in federal
court,225 arguing that the DEA acted arbitrarily and capriciously226 in violation of the APA.227
However, a registrant faces a difficult burden in convincing a court to enjoin the DEA’s
enforcement of the ISO pending resolution of the revocation or suspension proceedings.228 In

order to obtain such preliminary injunctive relief,229 a registrant “must establish that he is likely to
succeed on the merits, that he is likely to suffer irreparable harm in the absence of preliminary
relief, that the balance of equities tips in his favor, and that an injunction is in the public
interest.”230 The CSA provides that a reviewing court must use a “substantial evidence” standard
in considering the DEA’s findings of facts with respect to an ISO,231 though a court applies the
APA’s arbitrary and capricious standard of review when considering the DEA’s reason for
deciding to adopt, modify, or reject the ALJ’s recommendation concerning an ISO.232 A federal
appellate court has explained its review of the DEA’s issuance of an ISO under the APA as
follows: “To uphold DEA’s decision, ... we must satisfy ourselves that the agency examined the
relevant data and articulated a satisfactory explanation for its action including a rational
connection between the facts found and the choice made.”233
A registrant served with an ISO could also request “an expedited administrative hearing”234
before an ALJ on the merits of the revocation or suspension at a time before that indicated in the
OTSC.235 DEA regulations specify that the DEA Administrator “shall” grant the request for an
earlier hearing and “fix a date for such hearing as early as reasonably possible.”236

DEA’s Response to the Opioid Abuse Crisis
This section describes selected DEA actions intended to help alleviate the opioid crisis.

DEA Actions Against Registrants
As discussed earlier in this report, the CSA provides the DEA with a variety of criminal, civil, and
administrative tools to hold manufacturers, distributors, pharmacies, and physicians accountable
for actions that violate the CSA’s regulatory requirements. The DEA has used these authorities in

231 21 U.S.C. § 877 (“Findings of fact by the Attorney General, if supported by substantial evidence, shall be
conclusive.”). According to the Supreme Court, substantial evidence “means evidence which is substantial, that is,

more than a scintilla, and must do more than create a suspicion of the existence of the fact to be established.” NLRB v.

connection with the opioid crisis. For example, in February and March 2018, the DEA “surged its
enforcement and administrative resources” to target prescribers and pharmacies suspected of
diverting large amounts of opioid drugs, resulting in 147 revoked registrations and 28 arrests.237
In addition, in July 2017, CVS Pharmacy Inc. agreed to a $5 million settlement payment as well
as an administrative compliance plan with the DEA, to resolve the federal government’s
allegations that nine of its pharmacies in the Eastern District of California had failed to keep and
maintain accurate records of its controlled substances, in violation of the CSA’s recordkeeping
requirements.238 In early 2016, CVS also paid $8 million to the United States to settle allegations
that certain CVS pharmacies in Maryland had dispensed controlled substances, including the
opioids oxycodone, fentanyl, and hydrocodone, in violation of the CSA by failing to comply with
their duty to ensure that the prescriptions were issued for legitimate medical purposes.239 In 2013,
Walgreens agreed to pay $80 million in civil penalties to resolve DEA administrative actions and
civil penalty investigations concerning “an unprecedented number of record-keeping and
dispensing violations” occurring at six Walgreens pharmacies and a Walgreens drug distribution
center in Florida that allegedly resulted in oxycodone and other prescription opioids to be
diverted.240 As part of this settlement, Walgreens agreed to several terms and conditions,
including ending its practice of “compensat[ing] its pharmacists based on the volume of
prescriptions filled.”241
The DEA has also focused its attention on wholesale distributors of prescription opioids, which
ship the drugs from drug manufacturers to pharmacies, and their compliance with the CSA’s
recordkeeping and reporting requirements.242 Several DEA investigations into these wholesale
distributers resulted in civil penalty settlements. In January 2017, one of the largest U.S. drug
distributors, McKesson Corporation, agreed to pay a $150 million civil payment to resolve DEA
allegations that it had, in violation of CSA regulatory requirements, “failed to design and
implement an effective system to detect and report ‘suspicious orders’ for controlled substances
distributed to its independent and small chain pharmacy customers.”243 The federal government
alleged that “[f]rom 2008 until 2013, McKesson supplied various U.S. pharmacies an increasing
amount of oxycodone and hydrocodone pills, frequently misused products that are part of the

current opioid epidemic.”244 In addition to the monetary penalty, the settlement requires
McKesson to (1) suspend for several years sales of controlled substances from a number of its
distribution centers, (2) agree to certain “enhanced compliance obligations” that include periodic
auditing and staffing and organization improvements; and (3) accept the oversight of an
independent monitor to assess the company’s adherence with the compliance terms.245
Another major pharmaceutical drug distributor, Cardinal Health, Inc., agreed in December 2016
to pay $44 million to the federal government to settle allegations that it had failed to notify the
DEA when it filled unusually large and frequent orders for controlled substances requested by
pharmacies located in Maryland, Florida, and New York, and that it had failed to maintain
effective controls against diversion.246 The settlement agreement between Cardinal Health and the
federal government included an admission by the company that “from January 1, 2009 to May 14,
2012, it failed to report suspicious orders to the DEA as required by the CSA.”247
In 2014, the DEA took an administrative action to revoke the registration of Masters
Pharmaceuticals, Inc. (Masters), a bulk supplier of prescription medications to many U.S.
pharmacies, after concluding that the company had not satisfied its legal obligation to monitor
and report to the DEA suspicious orders for controlled substances.248 Masters had previously
entered into a settlement agreement with the DEA in 2009 in which Masters agreed to pay
$500,000 and implement a compliance system to detect suspicious orders of controlled
substances and prevent the substances from being diverted into illegal channels.249 However, in
the years following the settlement, the DEA grew to suspect that Masters’s employees were not
detecting and reporting to the DEA suspicious orders of oxycodone products.250 In 2013, the DEA
issued an Order to Show Cause why Masters’s registration should not be revoked, in light of
allegations that Masters had ignored its duty to report suspicious orders after its computer system
had flagged controlled substance orders that were unusual in size, frequency, or pattern.251 The
DEA Administrator concluded that Masters’s repeated violations of the suspicious orders
reporting requirement warranted revocation of its registration to distribute controlled
substances.252 Masters challenged the DEA’s revocation decision in federal court, arguing among
other things that the DEA’s factual conclusions were not supported by the record.253 In June 2017,
the U.S. Court of Appeals for the D.C. Circuit denied Masters’s petition for review, seeking to
overturn the DEA’s final order, after the court found “no prejudicial error in DEA’s decision.”254
In addition to these actions against distributors, the DEA has also investigated opioid
manufacturers for their failure to report suspicious orders of controlled substances that occurred
downstream in the drug supply chain. In July 2017, the DEA confirmed it had reached a $35

million civil penalty settlement with Mallinckrodt LLC, a drug manufacturer that is one of the
largest makers of the highly addictive generic pain reliever oxycodone.255 This settlement
resolved allegations that the company committed several violations of the CSA from 2008 until
2011 by supplying to drug distributors that, in turn, supplied pharmacies and pain clinics, “an
increasingly excessive quantity of oxycodone pills without notifying DEA of these suspicious
orders.”256 The DEA described this settlement as “groundbreaking” in part because it is the first
time the DEA has been able to hold a drug manufacturer responsible for detecting and reporting
suspicious orders relating to downstream sales between its distributor customers and the
distributors’ customers (pharmacies).257 This settlement agreement also apparently contains the
first public statement of the DEA’s position258 that “controlled substance manufacturers need to
go beyond ‘know your customer’ to use otherwise available company data to ‘know your
customer’s customer’ to protect these potentially dangerous pharmaceuticals from getting into the
wrong hands.”259 Under the settlement, Mallinckrodt agreed to analyze data it collects involving
“chargebacks,” which are reimbursements the company offers to their drug distributor customers
based on the distributor’s discounted sale of its drugs to pharmacies and pain clinics, in order to
monitor and report to the DEA any suspicious orders of oxycodone placed by the distributor’s
customers.260 Commentators have argued that the legal basis of the DEA imposing an obligation
on a drug manufacturer to “know your customer’s customer,” and its ability to hold the company
“responsible for what happens to its drugs once the distributors s
