In other cases, drug use may trigger or worsen those mental health conditions, particularly in people with specific vulnerabilities.43,44 In addition, some drugs, such as inhalants, may damage or destroy nerve cells, either in the brain or the peripheral nervous system (the nervous system outside the brain and spinal cord). Because addiction can affect so many aspects of a person’s life, treatment should address the needs of the whole person to be successful. Behavioral therapies can also enhance the effectiveness of medications and help people remain in treatment longer. When a person recovering from an addiction relapses, it indicates that the person needs to speak with their doctor to resume treatment, modify it, or try another treatment.52
However, when taken as prescribed by people with opioid use disorder, methadone and buprenorphine prevent drug cravings and withdrawal symptoms without causing the intense feelings of pleasure (or “high”) that other opioid drugs produce. However, starting naltrexone treatment may be harder for people using opioid drugs than starting buprenorphine or methadone treatment. For people with addictions to drugs like stimulants or cannabis, no medications are currently available to assist in treatment, so treatment consists of behavioral therapies. Research on the science of addiction and the treatment of substance use disorders has led to the development of research-based methods that help people to stop using drugs and resume productive lives, also known as being in recovery. Both methadone and buprenorphine bind to and activate the same mu-opioid receptors in the brain as do other opioid drugs. Like methadone, buprenorphine can reduce cravings and withdrawal symptoms without producing intense feelings of pleasure and intoxication in people who have opioid use disorder.
This may exacerbate their mental disorder in the long run, as well as increase the risk of developing addiction.43,44 Treatment for all conditions should happen concurrently. In some cases, mental disorders such as anxiety, depression, or schizophrenia may come before addiction. Detoxification alone without subsequent treatment generally leads to resumption of drug use. An overdose happens when the person uses enough of a drug to produce uncomfortable feelings, life-threatening symptoms, or death. If a person uses as much of the drug as they did before quitting, they can easily overdose because their bodies are no longer adapted to their previous level of drug exposure.
Why do some people become addicted to drugs, while others do not?
In general, the more risk factors a person has, the greater the chance that taking drugs will lead to drug use and addiction. Brain imaging studies of people with addiction show physical changes in areas of the brain that are critical to judgment, decision-making, learning and memory, and behavior control.12 These changes help explain the compulsive nature of addiction. Teachers, parents, and health care providers have crucial roles in educating young people and preventing drug use and addiction. The more risk factors a person has, the greater the chance that taking drugs can lead to addiction.

This makes methadone and buprenorphine less addictive. So, some people may think they are just substituting one drug for another. Buprenorphine treatment can also be started in the emergency department to ease withdrawal and cravings after an overdose.13 This can help motivate people to begin long-term treatment.
What other factors increase the risk of addiction?
Studies show that the majority of people who misuse buprenorphine do so to control withdrawal symptoms form other opioids, not to experience a high.25, 26 However, these effects are milder than those produced by dependence on other opioid drugs and can be managed by slowly reducing the medication dose rather than stopping it abruptly. Like many medications, methadone and buprenorphine do produce dependence.
When people enter treatment, addiction has often caused serious consequences in their lives, possibly disrupting their health and how they function in their family lives, at work, and in the community. Different types of medications may be useful at different stages of treatment to help a patient stop abusing drugs, stay in treatment, and avoid relapse. The chronic nature of addiction means that for some people relapse, or a return to drug use after an attempt to stop, can be part of the process, but newer treatments are designed to help with relapse prevention. Treatment enables people to counteract addiction’s disruptive effects on their brain and behavior and regain control of their lives.

What are the principles of effective treatment?
Addiction is a chronic disease characterized by drug seeking and use that is compulsive, or difficult to control, despite harmful consequences. Drugs change the brain in ways that make quitting hard, even for those who want to.
Why do so few people get medications for opioid use disorder?
- Both methadone and buprenorphine can be misused to achieve rewarding effects if injected instead of taken by mouth as prescribed.2 People without an opioid use disorder could experience a high when taking them orally.
- Stopping drug use is just one part of a long and complex recovery process.
- These medications include methadone, buprenorphine, and naltrexone.2 Another medication, lofexidine, is available to treat the acute symptoms of opioid withdrawal.3
- They may also help treat withdrawal symptoms that occur when people stop taking opioids and reduce drug cravings without creating the strongly pleasurable effects of opioid drugs.
Most drugs affect the brain’s “reward circuit,” causing euphoria as well as flooding it with the chemical messenger dopamine.

Drugs, Brains, and Behavior: The Science of Addiction
Biological factors that can affect a person’s risk of addiction include their genes, stage of development, or ethnicity. The initial decision to take drugs is typically voluntary. Occasional drug use, such as misusing an opioid to get high, can have similarly disastrous effects, including impaired driving and overdose.
Despite these advances, we still do not fully understand why some people develop an addiction to drugs or how drugs change the brain to foster compulsive drug use. Behavioral therapies help people in drug addiction treatment modify their attitudes and behaviors related to drug use. As with other diseases and disorders, the likelihood of developing an addiction differs from person to person, and no single factor determines whether a person will become addicted to drugs. Surges of dopamine in the reward circuit cause the reinforcement of pleasurable but unhealthy behaviors like taking drugs, leading people to repeat the behavior again and again.
The brain continues to develop into adulthood and undergoes dramatic changes during adolescence.
When people start opioid use disorder treatment, they usually must go to a program location every day or almost every day to receive their medication. In the United States, methadone is only available from approved opioid treatment programs when used to treat opioid use disorder. Methadone is an opioid medication that has been used for more than 50 years to treat opioid use disorder.4 It binds to and activates the same molecules on neurons (nerve cells), called mu-opioid receptors, as heroin, fentanyl, and other opioid drugs. A person is diagnosed with opioid use disorder if they have two or more of the symptoms and behaviors related to their opioid use listed in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, 5th Edition.
The medication lofexidine (Lucemyra®) is approved for treatment of withdrawal symptoms that can happen when people suddenly stop taking opioids. This is because a person usually needs to stop taking opioids for 7 to 10 days first.15 However, NIDA-supported research suggests that a faster treatment approach that reduces the waiting time to start naltrexone can also be effective.17 Naltrexone can be as effective as buprenorphine in helping people avoid returning to drug use when it is taken for a long period of time. Buprenorphine is another opioid medication that is used to treat opioid use disorder. However, methadone activates these receptors more slowly than those drugs and also remains in the body longer. There are FDA-approved medications that can help people stop or reduce opioid use.
However, naltrexone blocks the effects of opioids. Although it also binds to the mu-opioid receptor, naltrexone blocks the receptor, rather than activates it. When a person suddenly stops taking their medication abruptly, they may experience withdrawal symptoms. Any health care provider can prescribe naltrexone.
Some people may start to feel the need to take more of a drug or take it more often, even in the early stages of their drug use. When they first use a drug, people may perceive what seem to be positive effects. Therefore, education and outreach are key in helping people understand the possible risks of drug use. Results from NIDA-funded research have shown that prevention programs involving families, schools, communities, and the media are effective for preventing or reducing drug use and addiction. More good news is that drug use and addiction are preventable. These brain adaptations often lead to the person becoming less and less able to derive pleasure from other things they once enjoyed, like food, sex, or social activities.
Other products contain buprenorphine together with the overdose-reversal medication naloxone, including tablets or film to put under the tongue or film to place in the cheeks.9 We have identified many of the biological and environmental risk factors and are beginning to search for the genetic variations that contribute to the development and progression of the disorder.
