What is drug addiction?

Drug addiction is a chronic disease characterized by compulsive, or uncontrollable, drug seeking and use despite harmful consequences and changes in the brain, which can be long-lasting. These changes in the brain can lead to the harmful behaviors seen in people who use drugs. Drug addiction is also a relapsing disease. Relapse is the return to drug use after an attempt to stop. 

The path to drug addiction begins with the voluntary act of taking drugs. But over time, a person's ability to choose not to do so becomes compromised. Seeking and taking the drug becomes compulsive. This is mostly due to the effects of long-term drug exposure on brain function. Addiction affects parts of the brain involved in reward and motivation, learning and memory, and control over behavior. 

Addiction is a disease that affects both the brain and behavior. 

Can drug addiction be treated?

Yes, but it’s not simple. Because addiction is a chronic disease, people can’t simply stop using drugs for a few days and be cured. Most patients need long-term or repeated care to stop using completely and recover their lives.

Addiction treatment must help the person do the following:

  • stop using drugs
  • stay drug-free
  • be productive in the family, at work, and in society 

Principles of Effective Treatment

Based on scientific research since the mid-1970s, the following key principles should form the basis of any effective treatment program:

  • Addiction is a complex but treatable disease that affects brain function and behavior.
  • No single treatment is right for everyone.
  • People need to have quick access to treatment.
  • Effective treatment addresses all of the patient’s needs, not just his or her drug use.
  • Staying in treatment long enough is critical.
  • Counseling and other behavioral therapies are the most commonly used forms of treatment.
  • Medications are often an important part of treatment, especially when combined with behavioral therapies.
  • Treatment plans must be reviewed often and modified to fit the patient’s changing needs.
  • Treatment should address other possible mental disorders.
  • Medically assisted detoxification is only the first stage of treatment.
  • Treatment doesn't need to be voluntary to be effective.
  • Drug use during treatment must be monitored continuously.
  • Treatment programs should test patients for HIV/AIDS, hepatitis B and C, tuberculosis, and other infectious diseases as well as teach them about steps they can take to reduce their risk of these illnesses. 

What are treatments for drug addiction?

There are many options that have been successful in treating drug addiction, including:

  • behavioral counseling
  • medication
  • medical devices and applications used to treat withdrawal symptoms or deliver skills training
  • evaluation and treatment for co-occurring mental health issues such as depression and anxiety
  • long-term follow-up to prevent relapse

A range of care with a tailored treatment program and follow-up options can be crucial to success. 

Treatment should include both medical and mental health services as needed. Follow-up care may include community- or family-based recovery support systems.

How are medications and devices used in drug addiction treatment?

Medications and devices can be used to manage withdrawal symptoms, prevent relapse, and treat co-occurring conditions.

Withdrawal. Medications and devices can help suppress withdrawal symptoms during detoxification. Detoxification is not in itself "treatment," but only the first step in the process. Patients who do not receive any further treatment after detoxification usually resume their drug use. One study of treatment facilities found that medications were used in almost 80 percent of detoxifications (SAMHSA, 2014). In November 2017, the Food and Drug Administration (FDA) granted a new indication to an electronic stimulation device, NSS-2 Bridge, for use in helping reduce opioid withdrawal symptoms. This device is placed behind the ear and sends electrical pulses to stimulate certain brain nerves. Also, in May 2018, the FDA approved lofexidine, a non-opioid medicine designed to reduce opioid withdrawal symptoms. 

Relapse prevention. Patients can use medications to help re-establish normal brain function and decrease cravings. Medications are available for the treatment of opioid (heroin, prescription pain relievers), tobacco (nicotine), and alcohol addiction. Scientists are developing other medications to treat stimulant (cocaine, methamphetamine) and cannabis (marijuana) addiction. People who use more than one drug, which is very common, need treatment for all of the substances they use.

  • Opioids: Methadone (Dolophine®, Methadose®), buprenorphine (Suboxone®, Subutex®, Probuphine® , Sublocade™), and naltrexone (Vivitrol®) are used to treat opioid addiction. Acting on the same targets in the brain as heroin and morphine, methadone and buprenorphine suppress withdrawal symptoms and relieve cravings. Naltrexone blocks the effects of opioids at their receptor sites in the brain and should be used only in patients who have already been detoxified. All medications help patients reduce drug seeking and related criminal behavior and help them become more open to behavioral treatments. A NIDA study found that once treatment is initiated, both a buprenorphine/naloxone combination and an extended-release naltrexone formulation are similarly effective in treating opioid addiction. Because full detoxification is necessary for treatment with naloxone, initiating treatment among active users was difficult, but once detoxification was complete, both medications had similar effectiveness.
  • Tobacco: Nicotine replacement therapies have several forms, including the patch, spray, gum, and lozenges. These products are available over the counter. The U.S. Food and Drug Administration (FDA) has approved two prescription medications for nicotine addiction: bupropion (Zyban®) and varenicline (Chantix®). They work differently in the brain, but both help prevent relapse in people trying to quit. The medications are more effective when combined with behavioral treatments, such as group and individual therapy as well as telephone quitlines.
  • Alcohol: Three medications have been FDA-approved for treating alcohol addiction and a fourth, topiramate, has shown promise in clinical trials (large-scale studies with people). The three approved medications are as follows:
    • 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 patients. Genetic differences may affect how well the drug works in certain patients.
    • Acamprosate (Campral®) may reduce symptoms of long-lasting withdrawal, such as insomnia, anxiety, restlessness, and dysphoria (generally feeling unwell or unhappy). It may be more effective in patients with severe addiction.
    • Disulfiram (Antabuse®) interferes with the breakdown of alcohol. Acetaldehyde builds up in the body, leading to unpleasant reactions that include flushing (warmth and redness in the face), nausea, and irregular heartbeat if the patient drinks alcohol. Compliance (taking the drug as prescribed) can be a problem, but it may help patients who are highly motivated to quit drinking.
  • Co-occuring conditions: Other medications are available to treat possible mental health conditions, such as depression or anxiety, that may be contributing to the person’s addiction. 

How are behavioral therapies used to treat drug addiction?

Behavioral therapies help patients:

  • modify their attitudes and behaviors related to drug use
  • increase healthy life skills
  • persist with other forms of treatment, such as medication

Patients can receive treatment in many different settings with various approaches. 

Outpatient behavioral treatment includes a wide variety of programs for patients who visit a behavioral health counselor on a regular schedule. Most of the programs involve individual or group drug counseling, or both. These programs typically offer forms of behavioral therapy such as:

  • cognitive-behavioral therapy, which helps patients recognize, avoid, and cope with the situations in which they are most likely to use drugs
  • multidimensional family therapy—developed for adolescents with drug abuse problems as well as their families—which addresses a range of influences on their drug abuse patterns and is designed to improve overall family functioning
  • motivational interviewing, which makes the most of people's readiness to change their behavior and enter treatment
  • motivational incentives (contingency management), which uses positive reinforcement to encourage abstinence from drugs

Treatment is sometimes intensive at first, where patients attend multiple outpatient sessions each week. After completing intensive treatment, patients transition to regular outpatient treatment, which meets less often and for fewer hours per week to help sustain their recovery. In September 2017, the FDA permitted marketing of the first mobile application, reSET®, to help treat substance use disorders. This application is intended to be used with outpatient treatment to treat alcohol, cocaine, marijuana, and stimulant substance use disorders. In December 2018, the FDA cleared a mobile medical application, reSET®, to help treat opioid use disorders. This application is a prescription cognitive behavioral therapy and should be used in conjunction with treatment that includes buprenorphine and contingency management. 

Inpatient or residential treatment can also be very effective, especially for those with more severe problems (including co-occurring disorders). Licensed residential treatment facilities offer 24-hour structured and intensive care, including safe housing and medical attention. Residential treatment facilities may use a variety of therapeutic approaches, and they are generally aimed at helping the patient live a drug-free, crime-free lifestyle after treatment. Examples of residential treatment settings include:

  • Therapeutic communities, which are highly structured programs in which patients remain at a residence, typically for 6 to 12 months. The entire community, including treatment staff and those in recovery, act as key agents of change, influencing the patient’s attitudes, understanding, and behaviors associated with drug use. Read more about therapeutic communities in the Therapeutic Communities Research Report at https://www.drugabuse.gov/publications/research-reports/therapeutic-communities.
  • Shorter-term residential treatment, which typically focuses on detoxification as well as providing initial intensive counseling and preparation for treatment in a community-based setting.
  • Recovery housing, which provides supervised, short-term housing for patients, often following other types of inpatient or residential treatment. Recovery housing can help people make the transition to an independent life—for example, helping them learn how to manage finances or seek employment, as well as connecting them to support services in the community.

Is treatment different for criminal justice populations?

Scientific research since the mid-1970s shows that drug abuse treatment can help many drug-using offenders change their attitudes, beliefs, and behaviors towards drug abuse; avoid relapse, and successfully remove themselves from a life of substance abuse and crime. Many of the principles of treating drug addiction are similar for people within the criminal justice system as for those in the general population. However, many offenders don’t have access to the types of services they need. Treatment that is of poor quality or is not well suited to the needs of offenders may not be effective at reducing drug use and criminal behavior.

In addition to the general principles of treatment, some considerations specific to offenders include the following:

  • Treatment should include the development of specific cognitive skills to help the offender adjust attitudes and beliefs that lead to drug abuse and crime, such as feeling entitled to have things one’s own way or not understanding the consequences of one’s behavior. This includes skills related to thinking, understanding, learning, and remembering.
  • Treatment planning should include tailored services within the correctional facility as well as transition to community-based treatment after release.
  • Ongoing coordination between treatment providers and courts or parole and probation officers is important in addressing the complex needs of offenders re-entering society. 

Challenges of Re-entry

Drug abuse changes the function of the brain, and many things can "trigger" drug cravings within the brain. It’s critical for those in treatment, especially those treated at an inpatient facility or prison, to learn how to recognize, avoid, and cope with triggers they are likely to be exposed to after treatment. 

How many people get treatment for drug addiction?

According to SAMHSA's National Survey on Drug Use and Health, 22.5 million people (8.5 percent of the U.S. population) aged 12 or older needed treatment for an illicit* drug or alcohol use problem in 2014. Only 4.2 million (18.5 percent of those who needed treatment) received any substance use treatment in the same year. Of these, about 2.6 million people received treatment at specialty treatment programs (CBHSQ, 2015).

*The term "illicit" refers to the use of illegal drugs, including marijuana according to federal law, and misuse of prescription medications.
