Because drug abuse and addiction have so many dimensions and disrupt so many aspects of an individual's life, treatment is not simple. Effective treatment programs typically incorporate many components, each directed to a particular aspect of the illness and its consequences. Addiction treatment must help the individual stop using drugs, maintain a drug-free lifestyle, and achieve productive functioning in the family, at work, and in society. Because addiction is typically a chronic disease, people cannot simply stop using drugs for a few days and be cured. Most patients require long-term or repeated episodes of care to achieve the ultimate goal of sustained abstinence and recovery of their lives.
Too often, addiction goes untreated: According to SAMHSA's National Survey on Drug Use and Health (NSDUH), 23.2 million persons (9.4 percent of the U.S. population) aged 12 or older needed treatment for an illicit drug or alcohol use problem in 2007. Of these individuals, 2.4 million (10.4 percent of those who needed treatment) received treatment at a specialty facility (i.e., hospital, drug or alcohol rehabilitation or mental health center). Thus, 20.8 million persons (8.4 percent of the population aged 12 or older) needed treatment for an illicit drug or alcohol use problem but did not receive it. These estimates are similar to those in previous years.1
Principles of Effective Treatment
Scientific research since the mid–1970s shows that treatment can help patients addicted to drugs stop using, avoid relapse, and successfully recover their lives. Based on this research, key principles have emerged that should form the basis of any effective treatment programs:
Addiction is a complex but treatable disease that affects brain function and behavior.
No single treatment is appropriate for everyone.
Treatment needs to be readily available.
Effective treatment attends to multiple needs of the individual, not just his or her drug abuse.
Remaining in treatment for an adequate period of time is critical.
Counseling—individual and/or group—and other behavioral therapies are the most commonly used forms of drug abuse treatment.
Medications are an important element of treatment for many patients, especially when combined with counseling and other behavioral therapies.
An individual's treatment and services plan must be assessed continually and modified as necessary to ensure that it meets his or her changing needs.
Many drug–addicted individuals also have other mental disorders.
Medically assisted detoxification is only the first stage of addiction treatment and by itself does little to change long–term drug abuse.
Treatment does not need to be voluntary to be effective.
Drug use during treatment must be monitored continuously, as lapses during treatment do occur.
Treatment programs should assess patients for the presence of HIV/AIDS, hepatitis B and C, tuberculosis, and other infectious diseases as well as provide targeted risk–reduction counseling to help patients modify or change behaviors that place them at risk of contracting or spreading infectious diseases.
Effective Treatment Approaches
Withdrawal. Medications offer help in suppressing withdrawal symptoms during detoxification. However, medically assisted detoxification is not in itself "treatment"—it is only the first step in the treatment process. Patients who go through medically assisted withdrawal but do not receive any further treatment show drug abuse patterns similar to those who were never treated.
Treatment. Medications can be used to help reestablish normal brain function and to prevent relapse and diminish cravings. Currently, we have medications for opioids (heroin, morphine), tobacco (nicotine), and alcohol addiction and are developing others for treating stimulant (cocaine, methamphetamine) and cannabis (marijuana) addiction. Most people with severe addiction problems, however, are polydrug users (users of more than one drug) and will require treatment for all of the substances that they abuse.
Opioids: Methadone, buprenorphine and, for some individuals, naltrexone are effective medications for the treatment of opiate addiction. Acting on the same targets in the brain as heroin and morphine, methadone and buprenorphine suppress withdrawal symptoms and relieve cravings. Naltrexone works by blocking the effects of heroin or other opioids at their receptor sites and should only be used in patients who have already been detoxified. Because of compliance issues, naltrexone is not as widely used as the other medications. All medications help patients disengage from drug seeking and related criminal behavior and become more receptive to behavioral treatments.
Tobacco: A variety of formulations of nicotine replacement therapies now exist—including the patch, spray, gum, and lozenges—that are available over the counter. In addition, two prescription medications have been FDA–approved for tobacco addiction: bupropion and varenicline. They have different mechanisms of action in the brain, but both help prevent relapse in people trying to quit. Each of the above medications is recommended for use in combination with behavioral treatments, including group and individual therapies, as well as telephone quitlines.
Alcohol: Three medications have been FDA–approved for treating alcohol dependence: naltrexone, acamprosate, and disulfiram. A fourth, topiramate, is showing encouraging results in clinical trials. Naltrexone blocks opioid receptors that are involved in the rewarding effects of drinking and in the craving for alcohol. It reduces relapse to heavy drinking and is highly effective in some but not all patients—this is likely related to genetic differences. Acamprosate is thought to reduce symptoms of protracted withdrawal, such as insomnia, anxiety, restlessness, and dysphoria (an unpleasant or uncomfortable emotional state, such as depression, anxiety, or irritability). It may be more effective in patients with severe dependence. Disulfiram interferes with the degradation of alcohol, resulting in the accumulation of acetaldehyde, which, in turn, produces a very unpleasant reaction that includes flushing, nausea, and palpitations if the patient drinks alcohol. Compliance can be a problem, but among patients who are highly motivated, disulfiram can be very effective.
Behavioral Treatments
Behavioral treatments help patients engage in the treatment process, modify their attitudes and behaviors related to drug abuse, and increase healthy life skills. These treatments can also enhance the effectiveness of medications and help people stay in treatment longer. Treatment for drug abuse and addiction can be delivered in many different settings using a variety of behavioral approaches.
Outpatient behavioral treatment encompasses a wide variety of programs for patients who visit a clinic at regular intervals. Most of the programs involve individual or group drug counseling. Some programs also offer other forms of behavioral treatment such as—
cognitive–behavioral therapy, which seeks to help patients recognize, avoid, and cope with the situations in which they are most likely to abuse drugs
multidimensional family therapy, which was developed for adolescents with drug abuse problems—as well as their families—addresses a range of influences on their drug abuse patterns and is designed to improve overall family functioning
motivational interviewing, which capitalizes on the readiness of individuals to change their behavior and enter treatment
motivational incentives (contingency management), which uses positive reinforcement to encourage abstinence from drugs
Residential treatment programs can also be very effective, especially for those with more severe problems. For example, therapeutic communities (TCs) are highly structured programs in which patients remain at a residence, typically for 6 to 12 months. TCs differ from other treatment approaches principally in their use of the community—treatment staff and those in recovery—as a key agent of change to influence patient attitudes, perceptions, and behaviors associated with drug use. Patients in TCs may include those with relatively long histories of drug addiction, involvement in serious criminal activities, and seriously impaired social functioning. TCs are now also being designed to accommodate the needs of women who are pregnant or have children. The focus of the TC is on the resocialization of the patient to a drug-free, crime–free lifestyle.
Treatment Within the Criminal Justice System
Treatment in a criminal justice setting can succeed in preventing an offender's return to criminal behavior, particularly when treatment continues as the person transitions back into the community. Studies show that treatment does not need to be voluntary to be effective.
