Legal Issues Relating to the Disposal of Dispensed Controlled Substances 
 
Summary 
According to the White House Office of National Drug Control Policy, the intentional use of 
prescription drugs for non-medical purposes is the second most common form of illicit drug 
abuse among teenagers in the United States, behind marijuana use. Young adults and teens may 
find their parents’ prescription drugs in unsecured medicine cabinets or other obvious locations in 
the home, or they may retrieve expired or unwanted medication from the trash. It is believed that 
properly disposing of unwanted medications would help prevent prescription drug abuse by 
reducing the accessibility and availability of such drugs. Yet throwing prescription medications 
into the trash or flushing them down the toilet may not be environmentally acceptable. In 
response, many local communities and states have implemented pharmaceutical disposal 
programs (often referred to as drug “take-back” programs) that collect unused and unwanted 
medications from patients for incineration or other method of destruction that complies with 
federal and state laws.  
Prescription drugs may be categorized as either controlled substance medication or non-
controlled substance medication. Pharmaceutical controlled substances, such as narcotic pain 
relievers OxyContin® and Vicodin®, are among the most commonly abused prescription drugs. 
However, community take-back programs usually only accept non-controlled substance 
medication, in compliance with the federal Controlled Substances Act. This statute 
comprehensively governs all distributions of controlled substances, and it currently does not 
allow for a patient to deliver a controlled substance to another entity for disposal purposes unless 
law enforcement is present to assume custody of the controlled substances. As a consequence, 
patients seeking to reduce the amount of unwanted controlled substances in their possession have 
few alternative disposal options beyond discarding or flushing them. 
The 111th Congress has been interested in developing ways for patients to dispose of unused or 
unwanted pharmaceuticals that are efficient, secure, and environmentally friendly. Two pieces of 
legislation have been introduced, the Safe Drug Disposal Act of 2009 (H.R. 1191) and the Secure 
and Responsible Drug Disposal Act of 2009 (H.R. 1359, S. 1292), that would change the federal 
restrictions on disposal of controlled substances that have been dispensed to patients. This report 
describes the provisions of the Controlled Substances Act and its implementing regulations that 
relate to patient disposal of unwanted prescription medication, as well as provides an analysis of 
the pending legislation.

Legal Issues Relating to the Disposal of Dispensed Controlled Substances 
 
Introduction 
Prescription drug abuse1 is the second most common form of illicit drug abuse among teenagers 
in the United States, trailing only marijuana use.2 Controlled substances, such as the narcotic pain 
relievers OxyContin® and Vicodin®, are among the most often abused prescription drugs.3 
Young adults and teens may have easy access to prescription drugs via their parents’ medicine 
cabinets, from their friends or relatives, or they may retrieve expired or unwanted medication 
from the trash.4 A possible approach to addressing the prescription drug abuse problem is to 
reduce the availability of such drugs by patients disposing of unwanted medications that have 
been accumulating in their homes.5 Yet throwing prescription medications into the trash, flushing 
them down the toilet, or pouring them down a sink or drain—such that they end up in solid waste 
landfills or wastewater treatment systems—may have undesirable environmental consequences.6  
Many local and state government agencies have established drug disposal programs (often 
referred to as pharmaceutical “take-back” programs) to facilitate the collection of unused, 
unwanted, or expired medications for incineration or other method of destruction that complies 
with federal and state laws.7 However, these take-back programs often exclude controlled 
substance medications because federal law currently does not allow for a patient to deliver a 
controlled substance to another entity for disposal purposes, unless law enforcement is present to 
directly receive the controlled substances.8 As a consequence, those seeking to reduce the amount 
of unwanted controlled substances in their households have few alternative disposal options 
beyond discarding or flushing them.

Legal Issues Relating to the Disposal of Dispensed Controlled Substances 
 
Current Federal Guidelines on Proper Disposal of 
Prescription Drugs 
The White House Office of National Drug Control Policy (ONDCP) has issued the following 
recommendations regarding disposing of expired or unused prescription medications in such a 
way that makes it difficult for the drugs to be easily retrieved:9 
Federal Guidelines for Proper Disposal of Prescription Drugs 
•  Do not flush prescription drugs down the toilet or drain unless the label or 
accompanying patient information specifically instructs the patient to do so. 
•  Take advantage of community pharmaceutical drug take-back programs or other 
programs, such as household hazardous waste collection events, that collect 
drugs at a central location for proper disposal. 
•  In the event a drug take-back or collection program is not available: 
1.  Take the prescription drugs out of their original containers. 
2.  Mix drugs with an undesirable substance, such as used coffee grounds or 
kitty litter. 
3.  Put this mixture into disposable containers with a lid, such as an empty 
margarine tub, or into a sealable bag. 
4.  Conceal or remove any personal information, including the Rx number, on 
the empty containers by covering it with black permanent marker or duct 
tape, or by scratching it off. 
5.  Place the sealed container with the mixture, and the empty drug containers, 
into the trash. 
This consumer guidance was developed in collaboration with the U.S. Food and Drug 
Administration (FDA).10 In addition, a public-private collaboration between the U.S. Fish and 
Wildlife Service, the American Pharmacists Association, and the Pharmaceutical Research and 
Manufacturers of America has produced a national campaign called “SMARxT DISPOSAL™,” 
to provide information regarding the safe disposal of medication and to raise public awareness 
about the possible environmental impacts from improper disposal of drugs.11 The advice 
disseminated under the SMARxT DISPOSAL™ campaign regarding unused medication disposal 
is substantially similar to that offered by the ONDCP and FDA.

Legal Issues Relating to the Disposal of Dispensed Controlled Substances 
 
However, while the federal guidelines encourage consumers to utilize community pharmaceutical 
drug take-back programs, the current legal restrictions on collecting controlled substances 
necessarily limit many programs. In January 2009, in response to the concerns raised about these 
impediments, the Drug Enforcement Administration (DEA), an agency within the U.S. 
Department of Justice, requested public comments in advance of a proposed rulemaking to permit 
the disposal of dispensed controlled substances in a manner that is consistent with the federal 
Controlled Substances Act.12 As of the date of this report, the DEA has not yet promulgated a 
regulation concerning this matter. 
This report presents an overview of the Controlled Substances Act and its implementing 
regulations that relate to patient disposal of unwanted prescription medication, as well as 
describes legislation introduced in the 111th Congress that would amend federal law to provide for 
more accessible methods of secure and environmentally responsible disposal of dispensed 
controlled substances. 
Overview of the Controlled Substances Act 
Most prescription drugs are not controlled substances13 and therefore are not regulated under the 
Comprehensive Drug Abuse Prevention and Control Act of 1970, commonly referred to as the 
Controlled Substances Act (CSA).14 However, some prescription drugs—in particular those most 
susceptible to abuse such as narcotics and opiates that are often used in the treatment of pain15—
come within the purview of the CSA because they have a greater potential for abuse than other 
prescription drugs and may lead to physical and psychological dependence. Enacted in 1970, the 
CSA is designed to regulate and facilitate the use of controlled substances for legitimate medical, 
scientific, research, and industrial purposes and to prevent these substances from being diverted 
for illegal purposes. By delegation from the U.S. Attorney General, the DEA is responsible for 
administering and enforcing the CSA and its implementing regulations. 16 
The CSA assigns various plants, drugs, and chemicals to one of five schedules, ranging from 
Schedule I, which contains substances that have no currently accepted medical use in treatment 
and cannot safely be made available under prescription (such as heroin), to Schedules II, III, IV, 
and V, which include substances that have recognized medical uses and may be manufactured, 
distributed, and used in accordance with the CSA.17 The order of the schedules reflects substances 
that are progressively less dangerous and addictive.18 Schedule II narcotics include the drugs

efficacy of all kinds of prescription medications (controlled and non-controlled substances), including the approval, 
manufacturing, and distribution of such drugs.

morphine, codeine, and OxyContin®. Schedule III substances include Vicodin® and anabolic 
steroids, while Schedule IV includes Xanax® and Valium®. Schedule V contains, among other 
things, cough medicines that contain a limited amount of codeine (Robitussin AC®).19 
Prescriptions for Controlled Substances 
It is unlawful for any person to prescribe or dispense controlled substances without first 
registering with the DEA Administrator.20 No controlled substance that is a prescription drug (as 
determined under § 503(b) of the Federal Food, Drug, and Cosmetic Act) assigned to Schedules 
II, III, IV, and V may be dispensed without a prescription.21 A prescription for a controlled 
substance may be issued only for a “legitimate medical purpose” by a physician “acting in the 
usual course of his professional practice.”22 The CSA authorizes the DEA Administrator to 
suspend or revoke a physician’s prescription privileges upon a finding that the physician has 
“committed such acts as would render his registration ... inconsistent with the public interest.”23 
In determining the public interest, the DEA Administrator is required to consider the following 
factors:24 
•  the recommendation of the appropriate state licensing board or professional 
disciplinary authority 
•  the applicant’s experience in dispensing, or conducting research with respect to 
controlled substances 
•  the applicant’s conviction record under federal or state laws relating to the 
manufacture, distribution, or dispensing of controlled substances 
•  compliance with applicable state, federal, or local laws relating to controlled 
substances 
•  such other conduct which may threaten the public health and safety 
CSA Regulatory Scheme 
The regulatory structure of the CSA creates a “closed system” in which distribution of controlled 
substances may lawfully occur among registered handlers.25 The CSA places several regulatory 
requirements upon legitimate handlers of controlled substances, including registration, providing 
effective security, recordkeeping, and reporting.26 Every person who manufactures, distributes, 
dispenses, imports, or exports any controlled substance, or who proposes to engage in the

manufacture, distribution, dispensing, importation, or exportation of any controlled substance, 
must obtain a registration issued by the DEA (unless exempt).27 Manufacturers and distributers of 
controlled substances must register 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.28 
Registrations specify the extent to which registrants are authorized to manufacture, possess, 
distribute, or dispense controlled substances. All registrants must provide “effective controls and 
procedures” to prevent the theft or diversion of the controlled substances in their possession.29 In 
addition, the CSA imposes accountability requirements on all registered handlers of controlled 
substances. Registrants must keep strict records and maintain inventories in compliance with 
federal law and rules adopted by the relevant state.30 For example, a registrant must maintain a 
complete and accurate record of each substance manufactured, received, sold, delivered, or 
otherwise disposed of by the registrant.31 Registrants must also complete and submit to the DEA 
periodic reports of every sale, delivery, or other disposal of any controlled substance.32  
The DEA has described the movement of a controlled substance from manufacture to the patient 
as follows: 
[A] controlled substance, after being manufactured by a DEA-registered manufacturer, may 
be transferred to a DEA-registered distributor for subsequent distribution to a DEA- 
registered retail pharmacy. After a DEA-registered practitioner, such as a physician or a 
dentist, issues a prescription for a controlled substance to a patient (i.e., the ultimate user), 
that patient can fill that prescription at a retail pharmacy to obtain that controlled substance. 
In this system, the manufacturer, the distributor, the practitioner, and the retail pharmacy are 
all required to be DEA registrants, or to be exempted from the requirement of registration, to 
participate in the process.33 
This “closed system” of distribution guarantees that a particular controlled substance is always 
under the control of a DEA-registered person until it reaches the patient or is destroyed, and the 
CSA’s regulatory requirements “ensure that all controlled substances are accounted for from their 
creation until their dispensing or destruction.”34 
CSA Civil and Criminal Penalties 
For persons who lawfully handle controlled substances, failure to comply with the regulatory 
requirements of the CSA may result in civil penalties involving fines.35 Examples of violations 
include the distribution or dispensing of a controlled substance not authorized by the person’s 
registration with the DEA, as well as the refusal or failure to make, keep, or furnish any record or 
                                                
27 21 U.S.C. § 822; 21 C.F.R. §§ 1301.22-1301.26 (exempting agents of registrants, certain military personnel, and law 
enforcement officials from DEA registration requirements).

report required under the CSA. The CSA provides that violations of its regulatory requirements 
generally do not constitute a crime,36 unless the violation was committed knowingly, in which 
case imprisonment of up to one or two years is authorized.37   
The CSA provides a variety of criminal sanctions for unlawful possession, manufacturing, 
distribution, or importation of controlled substances. The CSA outlaws simple possession of 
controlled substances regardless of intent, stating that, “It shall be unlawful for any person 
knowingly or intentionally to possess a controlled substance ... ” 38 However, the CSA permits 
patients to possess a controlled substance that “was obtained directly, or pursuant to a valid 
prescription or order, from a practitioner, while acting in the course of his professional practice.... 
”39 Any person who violates the simple possession offense may be sentenced to a term of 
imprisonment of not more than one year, and fined a minimum of $1,000, or both.40 A second 
violation raises the minimum fine to $2,500 and a minimum imprisonment term of 15 days with a 
maximum of two years; a third offense carries a minimum fine of $5,000 and minimum 
imprisonment for 90 days, with a maximum term of three years.41 
The CSA also prohibits any person from knowingly or intentionally acquiring or obtaining 
possession of a controlled substance by misrepresentation, fraud, forgery, deception, or 
subterfuge.42 A violation of this section 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 increases 
the maximum imprisonment term to eight years.43 
The CSA broadly defines “distribution” to include virtually every transfer of possession.44 
Dispensing a controlled substance means “to deliver a controlled substance to an ultimate user ... 
by, or pursuant to the lawful order of, a practitioner, including the prescribing and administering 
of a controlled substance.”45 The term “deliver” means “the actual, constructive, or attempted 
transfer of a controlled substance or a listed chemical, whether or not there exists an agency 
relationship.”46 It is unlawful for any person knowingly or intentionally to distribute or dispense, 
or to possess with intent to distribute or dispense, a controlled substance, except as authorized by 
law.47 The criminal penalties for violating this prohibition on unlawful distribution of a controlled 
substance 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.48 For example,

a violation of § 841(a) 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 $1,000,000.49 For a 
second offense, the fine increases to $2,000,000 and the maximum imprisonment term increases 
to 30 years. 
Disposal of Controlled Substances 
Disposal By DEA Registrants 
DEA registrants may need to dispose of controlled substances in their possession when they are 
expired, unusable, or unwanted. Under the CSA and DEA regulations, there are three different 
options for registrants to dispose of controlled substances:50 
1.  The distributor or dispenser may return the controlled substance to the 
pharmaceutical manufacturer who accepts returns of outdated or damaged 
controlled substances. 
2.  The distributor, dispenser, or manufacturer may itself dispose of the 
controlled substances under procedures specified by federal regulation, 13 
C.F.R. § 1307.21.51 
3.  The distributor, dispenser, or manufacturer may transfer the controlled 
substances to a “reverse distributor” to take custody of the controlled 
substances for the purpose of returning them to the manufacturer or arranging 
for their disposal.52 
Disposal By Ultimate Users 
While disposal of controlled substances by DEA registrants is governed by the federal regulations 
described above (and also perhaps local, county, or state environmental and waste disposal laws), 
disposal of controlled substances by patients is left to their discretion. The CSA and DEA 
regulations are largely silent on the ways in which patients may discard controlled substances that 
have been dispensed to them.

51 Under 13 C.F.R. § 1307.21, any person may request permission from DEA to dispose of controlled substances 
without the need for a DEA or state government witness. If a registrant has a regular need to dispose of controlled 
substances, the DEA may grant blanket authorization for such disposal; however, “DEA normally requires that the 
registrant provide two designated responsible individuals to accompany the drugs to the disposal site and witness the 
destruction.” DEA, Definition and Registration of Reverse Distributors, 70 Fed. Reg. 22591 (May 2, 2005).  
52 A “reverse distributor” is a DEA-registered entity “who receives controlled substances acquired from another DEA 
registrant for the purpose of—(1) returning unwanted, unusable, or outdated controlled substances to the manufacturer 
or the manufacturer’s agent; or (2) where necessary, processing such substances or arranging for processing such 
substances for disposal.” 21 C.F.R. 1300.01(b)(41).

Legal Issues Relating to the Disposal of Dispensed Controlled Substances 
 
The CSA refers to an individual patient as an “ultimate user,” meaning “a person who has 
lawfully obtained, and who possesses, a controlled substance for his own use or for the use of a 
member of his household or for an animal owned by him or by a member of his household.”53 
Ultimate users are not required to register with the DEA54 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.”55 Therefore, an individual patient may dispose 
of a controlled substance prescription medication without prior approval from the DEA, or 
without notifying any legal authority beforehand or afterwards. 
However, DEA regulations do permit any person in possession of any controlled substance, 
including both registrants and non-registrants, to request assistance with disposal of such 
substance from the DEA Special Agents in Charge (SAC) of the area where the person is 
located.56 An ultimate user who seeks the help of the DEA in disposing of a controlled substance 
must submit a letter to the SAC that provides several pieces of information, including the 
following: (1) the user’s name and address; (2) the name and quantity of the controlled substance 
to be disposed of; (3) how the applicant obtained the substance (if known); and (4) the name, 
address, and DEA registration number of the person who possessed the controlled substance 
before the user (if known).57 Upon receipt of this letter, a SAC may authorize the ultimate user to 
dispose of the controlled substance by one of the following methods: (1) by transfer to a DEA 
registrant; (2) by delivery to a DEA agent or to the nearest DEA field office; (3) by destruction in 
the presence of a DEA agent; or (4) by “such other means as the Special Agent in Charge may 
determine to assure that the substance does not become available to unauthorized persons.”58 The 
DEA has conceded that ultimate users have very rarely utilized this procedure that is available to

The DEA’s website and the agency’s comments published in the Federal Register have repeatedly 
asserted the DEA’s view that the CSA prohibits consumers from returning unwanted or unused 
controlled substances to their pharmacies or giving them to other DEA-registered entities for 
disposal purposes.60 The DEA has stated that the CSA has no provisions that allow a DEA 
registrant (such as a pharmacy) to accept and take custody of controlled substances from a non-
registrant (individual patient).61 The DEA has previously explained the following:

Legal Issues Relating to the Disposal of Dispensed Controlled Substances 
 
The Controlled Substances Act is unique among criminal laws in that it stipulates acts 
pertaining to controlled substances that are permissible. That is, if the CSA does not 
explicitly permit an action pertaining to a controlled substance, then by its lack of explicit 
permissibility the act is prohibited.62 
Not only does the CSA lack provisions that permit the transfer of a controlled substance between 
non-registrants and DEA registrants, but the CSA expressly prohibits an ultimate user to engage 
in “distribution” of a controlled substance.63 Because the CSA defines “distribute” to mean 
“deliver ... a controlled substance”64 and further defines “deliver” to mean “the actual, 
constructive, or attempted transfer of a controlled substance,”65 it is illegal for an ultimate user to 
give a controlled substance to another person (whether DEA-registered or not) for disposal 
purposes.66 
Some state and community drug take-back programs accept controlled substances from patients 
because they have been granted “temporary allowances” from the DEA to do so—such programs 
involve the participation of law enforcement agencies that have sought authorization from the 
SAC to directly receive the controlled substances from ultimate users for disposal purposes.67 In 
the absence of such DEA approval, however, community pharmaceutical take-back programs are 
not permitted to collect controlled substances from consumers. 
Legislation in the 111th Congress 
Several bills have been introduced in the 111th Congress that would change current law and make 
it easier for patients to dispose of unused controlled substances by participating in drug take-back 
programs or delivering them to entities authorized by law to dispose of them. Introduced on 
February 25, 2009, by Representative Inslee, the Safe Drug Disposal Act of 2009 (H.R. 1191) 
would amend the CSA to allow states to operate drug disposal programs that accept from patients 
unwanted or unused controlled substances without requiring the presence of law enforcement 
personnel.68 Specifically, the bill would direct the Attorney General to promulgate regulations that 
describe five drug take-back program models from which states may choose and implement, to

also, e.g., 21 U.S.C. § 841(a) (“Except as authorized by this subchapter, it shall be unlawful for any person knowingly 
or intentionally—(1) to manufacture, distribute, or dispense, or possess with intent to manufacture, distribute, or 
dispense, a controlled substance; or (2) to create, distribute, or dispense, or possess with intent to distribute or dispense, 
a counterfeit substance.”) (emphasis added). 
63 21 U.S.C. § 841(a)(1) (“Except as authorized by this title, it shall be unlawful for any person knowingly or 
intentionally to ... distribute ... a controlled substance”); DEA, Disposal of Controlled Substances by Persons Not 
Registered With the Drug Enforcement Administration, 74 Fed. Reg. 3480, 3481 (Jan. 21, 2009) (“[T]he CSA and its 
implementing regulations do not contemplate a situation in which an ultimate user would distribute controlled 
substances.”)

68 155 CONG. REC. E386 (daily ed. Feb. 25, 2009) (statement of Rep. Jay Inslee) (“[T]he Controlled Substances Act has 
inadvertently established a barrier between safe and unsafe disposal methods of unused or unwanted controlled 
substances. Without amending this law, controlled substance abuse on our streets and prescription drug pollution of our 
water ways will continue to rise.”).

Legal Issues Relating to the Disposal of Dispensed Controlled Substances 
 
permit an ultimate user (or a care taker)69 to dispose of unused or partially used controlled 
substances through delivery to a designated facility. Beyond these five model state programs, the 
regulations must also allow states to devise an alternative means of disposal that best suits the 
state and that receives the approval of the Attorney General. The bill requires that any approved 
state drug disposal program must, among other things, permit ultimate users to dispose of 
controlled substances through non-law-enforcement personnel and incorporate environmentally 
sound practices for disposal. Furthermore, the bill would amend Section 505 of the Federal Food, 
Drug, and Cosmetic Act70 and Section 351 of the Public Health Service Act71 to require the 
Secretary of Health and Human Services to ensure that the labeling for drugs or biological 
products does “not include any recommendation or direction to dispose of the drug by means of a 
public or private wastewater treatment system, such as by flushing down the toilet.”72  
The Secure and Responsible Drug Disposal Act of 2009 (H.R. 1359, S. 1292), introduced by 
Representative Stupak on March 5, 2009, and Senator Klobuchar on June 18, 2009, would amend 
the CSA to allow an ultimate user—without being registered—to deliver controlled substances to 
an entity that is authorized under the CSA to dispose of them, providing that such disposal occurs 
in accordance with regulations issued by the Attorney General to prevent diversion of controlled 
substances. Also, the bill would grant the Attorney General discretion to promulgate regulations 
that authorize long-term care facilities to dispose of controlled substances on behalf of ultimate 
users.
