Well-known and well-documented connection
between criminal activity and substance abuse
Three types of offenses
 drug possession or sales
 related to drug abuse (e.g., stealing to get money for
drugs)
 related to a lifestyle that predisposes the drug abuser
to engage in illegal activity

Many offenses, including violent crime, are
committed by people who have substance abuse
disorders

Drug law violations are the most common
type of criminal offense (Glaze and Bonczar 2009) ,
1,305,191 arrests (FBI’s Uniform Crime Reporting (UCR) Program 2009)

Estimated Number of Buprenorphine- and Hydromorphone-Related
ED Visits More Than Doubles from 2006 to 2010
The estimated number of emergency department (ED) visits related to the nonmedical use of opioid pain killers increased 79% from 201,280
in 2006 to 359,921 in 2010, according to the most recent data from the Drug Abuse Warning Network (DAWN). The greatest increases were
seen in buprenorphine- and hydromorphone-related ED visits. In 2006, the nonmedical use of buprenorphine was involved as either a direct
cause or a contributing factor in an estimated 4,440 ED visits, compared to 15,778 in 2010—an increase of 255%. The estimated number of
visits related to the nonmedical use of hydromorphone increased 161% over the same 5-year period (see figure below). While the number of
ED visits for the nonmedical use of buprenorphine and hydromorphone is relatively small compared to other opioid pain relievers, the
magnitude of the increase suggests that there may be emerging problems with the nonmedical use of these drugs that warrant the
monitoring of their use and related consequences.

The New Your Times, July 2, 2013
Drug addiction is a complex illness—characterized by
intense and, at times, uncontrollable drug craving,
along with compulsive drug seeking and use that
persist even in the face of devastating consequences.
 Addiction produces far-reaching health and social
consequences:

 increases a person’s risk for a variety of other mental and
physical illnesses
 interferes with a person’s normal functioning in the family,
the workplace, and the broader community

Effective treatment programs typically incorporate
many components, including pharmacotherapies.



Medications can be an important component
of effective drug abuse treatment for
offenders.
By allowing the brain to function more
normally, they enable the addicted person to
leave behind a life of crime and drug abuse.
Addiction medications are underused in the
treatment of drug abusers within the criminal
justice system, despite evidence of their
effectiveness.
Heroin, morphine, and some prescription
painkillers (e.g., OxyContin, Vicodin, and
Fentanyl) are all opiates.
 They act on specific (opiate) receptors in the
brain
 Interact with naturally produced substances
known as endorphins or enkephalins– important
in regulating pain and emotion
 Opiates as a general class of drugs have
significant abuse liability.


Methadone maintenance therapy:
 In the 1960's, methadone gained recognition as an
effective treatment for heroin addiction.
 Administered daily, methadone treatment is
currently regulated so that only specialized clinics
can provide it.
 Patients’ illicit opioid use declines, often
dramatically, during methadone maintenance
treatment1.

Journal of Drug and Alcohol Abuse 1993;19:65-78.

Buprenorphine
 Long-acting partial agonist that acts on the same
receptors as heroin and morphine
 Relieves drug cravings without producing the same
intense “high” or dangerous side effects.
 Abuse-deterrent formulation with naloxone
▪ Naloxone has no effect when Suboxone is taken as prescribed, but if
an addicted individual attempts to inject Suboxone, the naloxone
will produce severe withdrawal symptoms
 Currently available in two formulations that are taken
sublingually:
▪ a pure form of the drug
▪ a more commonly prescribed formulation called Suboxone (a
combination with naloxone)

NIDA-supported basic
and clinical research
showed that, alone or
in combination with
naloxone,
buprenorphine
significantly reduced
opiate drug abuse and
cravings and was a safe
and acceptable
addiction treatment.


Simply substituting one addictive drug for another?
Taking these medications as prescribed allows
patients to
 hold jobs,
 avoid street crime and violence,
 and reduce their exposure to HIV by stopping or
decreasing injection drug use and drug-related high-risk
sexual behavior.

Patients stabilized on these medications can also
engage more readily in counseling and other
behavioral interventions essential to recovery.




Condemns denying patients long-term
maintenance treatment with methadone or
buprenorphine
“A particular form of ill-treatment and
possibly torture of drug users is the denial of
opiate substitution treatment”
Considered a human rights violation when it
occurs in jails and prisons


Naltrexone
 an opioid receptor blocker, or antagonist—it blocks




opioids from binding to their receptors and thereby
prevents their euphoric and other effects.
Highly effective in reversing the effects of opiate
overdose
No potential for abuse, and it is not addictive
Noncompliance is a common problem
Best suited for highly motivated, recently detoxified
patients who desire total abstinence because of
external circumstances




Revia
Daily pill
Problem is medication compliance
Subject to diversion

Vivitrol
 long-acting injectable version of naltrexone,
called Vivitrol, was approved to treat opioid
addiction.
 Because it only needs to be delivered once a
month, this version of the drug can facilitate
compliance
Offers an alternative for those who do not wish to
be placed on agonist/partial agonist medications
 Side effects such as injection site reactions

Intoxication can impair brain function and motor
skills.
 Heavy use can increase risk of certain cancers,
stroke, and liver disease.
 Alcoholism or alcohol dependence is a
diagnosable disease characterized by

 a strong craving for alcohol,
 and/or continued use despite harm or personal injury.

Alcohol abuse, which can lead to alcoholism, is a
pattern of drinking that results in harm to one's
health, interpersonal relationships, or ability to
work.

Acamprosate (Campral®)
 acts on the gamma-aminobutyric acid (GABA) and
glutamate neurotransmitter systems
 Reduces symptoms of protracted withdrawal,
such as insomnia, anxiety, restlessness, and
dysphoria.
 Has been shown to help dependent drinkers
maintain abstinence for several weeks to months,
 May be more effective in patients with severe
dependence.

Disulfiram (Antabuse®)
 Interferes with degradation of alcohol,
 Causes accumulation of acetaldehyde, which, in turn,




produces a very unpleasant reaction that includes flushing,
nausea, and palpitations if a person drinks alcohol.
Utility and effectiveness are limited because compliance is
generally poor.
Can be effective among patients who are highly motivated
Some patients use it episodically for high-risk situations
It can also be administered in a monitored fashion, such as
in a clinic or by a spouse, improving its efficacy.

Naltrexone
 blocks opioid receptors that are involved in the
rewarding effects of drinking and the craving for
alcohol.
 It has been shown to reduce relapse to problem
drinking in some patients.
 Vivitrol also FDA-approved for treating
alcoholism, and may offer benefits regarding
compliance.

Topiramate
 Is thought to work by increasing inhibitory (GABA)
neurotransmission and reducing stimulatory
(glutamate) neurotransmission
 Precise mechanism of action is not known.
 Although it has not yet received FDA approval for
treating alcohol addiction, it is sometimes used offlabel for this purpose.
 Topiramate has been shown in studies to significantly
improve multiple drinking outcomes, compared with
a placebo.

Treatment is an effective intervention for drug
abusers, including those who are involved with
the criminal justice system.
 One of the goals of treatment planning is to
match evidence-based interventions to
individual needs at each stage of drug
treatment.
 Pharmacotherapy, one viable treatment option,
can help normalize brain function and facilitate
abstinence.
