Principles of Drug Addiction Treatment: A Research Based Guide


Frequently Asked Questions

3. How effective is drug addiction treatment?

In addition to stopping drug use, the goal of treatment is to return the individual to productive functioning in the family, workplace, and community. Measures of effectiveness typically include levels of criminal behavior, family functioning, employability, and medical condition. Overall, treatment of addiction is as successful as treatment of other chronic diseases, such as diabetes, hypertension, and asthma.

Treatment of addiction is as successful as treatment of other chronic diseases such as diabetes, hypertension, and asthma.

According to several studies, drug treatment reduces drug use by 40 to 60 percent and significantly decreases criminal activity during and after treatment. For example, a study of therapeutic community treatment for drug offenders (See Treatment Section) demonstrated that arrests for violent and nonviolent criminal acts were reduced by 40 percent or more. Methadone treatment has been shown to decrease criminal behavior by as much as 50 percent. Research shows that drug addiction treatment reduces the risk of HIV infection and that interventions to prevent HIV are much less costly than treating HIV-related illnesses. Treatment can improve the prospects for employment, with gains of up to 40 percent after treatment.

Although these effectiveness rates hold in general, individual treatment outcomes depend on the extent and nature of the patient's presenting problems, the appropriateness of the treatment components and related services used to address those problems, and the degree of active engagement of the patient in the treatment process.


4. How long does drug addiction treatment usually last?

Individuals progress through drug addiction treatment at various speeds, so there is no predetermined length of treatment. However, research has shown unequivocally that good outcomes are contingent on adequate lengths of treatment. Generally, for residential or outpatient treatment, participation for less than 90 days is of limited or no effectiveness, and treatments lasting significantly longer often are indicated. For methadone maintenance, 12 months of treatment is the minimum, and some opiate-addicted individuals will continue to benefit from methadone maintenance treatment over a period of years.

Good outcomes are contingent on adequate lengths of treatment.

Many people who enter treatment drop out before receiving all the benefits that treatment can provide. Successful outcomes may require more than one treatment experience. Many addicted individuals have multiple episodes of treatment, often with a cumulative impact.


5. What helps people stay in treatment?

Since successful outcomes often depend upon retaining the person long enough to gain the full benefits of treatment, strategies for keeping an individual in the program are critical. Whether a patient stays in treatment depends on factors associated with both the individual and the program. Individual factors related to engagement and retention include motivation to change drug-using behavior, degree of support from family and friends, and whether there is pressure to stay in treatment from the criminal justice system, child protection services, employers, or the family. Within the program, successful counselors are able to establish a positive, therapeutic relationship with the patient. The counselor should ensure that a treatment plan is established and followed so that the individual knows what to expect during treatment. Medical, psychiatric, and social services should be available.

Whether a patient stays in treatment depends on factors associated with both the individual and the program.

Since some individual problems (such as serious mental illness, severe cocaine or crack use, and criminal involvement) increase the likelihood of a patient dropping out, intensive treatment with a range of components may be required to retain patients who have these problems. The provider then should ensure a transition to continuing care or "aftercare" following the patient's completion of formal treatment.


6. Is the use of medications like methadone simply replacing one drug addiction with another?

No. As used in maintenance treatment, methadone and LAAM are not heroin substitutes. They are safe and effective medications for opiate addiction that are administered by mouth in regular, fixed doses. Their pharmacological effects are markedly different from those of heroin.

As used in maintenance treatment, methadone and LAAM are not heroin substitutes.

Injected, snorted, or smoked heroin causes an almost immediate "rush" or brief period of euphoria that wears off very quickly, terminating in a "crash." The individual then experiences an intense craving to use more heroin to stop the crash and reinstate the euphoria. The cycle of euphoria, crash, and craving - repeated several times a day - leads to a cycle of addiction and behavioral disruption. These characteristics of heroin use result from the drug's rapid onset of action and its short duration of action in the brain. An individual who uses heroin multiple times per day subjects his or her brain and body to marked, rapid fluctuations as the opiate effects come and go. These fluctuations can disrupt a number of important bodily functions. Because heroin is illegal, addicted persons often become part of a volatile drug-using street culture characterized by hustling and crimes for profit.

Methadone and LAAM have far more gradual onsets of action than heroin, and as a result, patients stabilized on these medications do not experience any rush. In addition, both medications wear off much more slowly than heroin, so there is no sudden crash, and the brain and body are not exposed to the marked fluctuations seen with heroin use. Maintenance treatment with methadone or LAAM markedly reduces the desire for heroin. If an individual maintained on adequate, regular doses of methadone (once a day) or LAAM (several times per week) tries to take heroin, the euphoric effects of heroin will be significantly blocked. According to research, patients undergoing maintenance treatment do not suffer the medical abnormalities and behavioral destabilization that rapid fluctuations in drug levels cause in heroin addicts.
