For example, it is now well-known that tobacco smoke can cause many cancers, methamphetamine can cause severe dental problems, known as meth mouth, and that opioids can lead to overdose and death. Imaging scans, chest X-rays, and blood tests can show the damaging effects of long-term drug use throughout the body. Stopping drug use is just one part of a long and complex recovery process. Treatment should be tailored to address each patient’s drug use patterns and drug-related medical, mental, and social problems. Medications are also available to help treat addiction to alcohol and nicotine. Relapse rates for drug use are similar to rates for other chronic medical illnesses.

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.

• Fortunately, researchers know more than ever about how drugs affect the brain and have found treatments that can help people recover from drug addiction and lead productive lives.
• They may mistakenly think that those who use drugs lack moral principles or willpower and that they could stop their drug use simply by choosing to.
• 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.
• Today, thanks to science, our views and our responses to addiction and the broader spectrum of substance use disorders have changed dramatically.

Most drugs affect the brain’s “reward circuit,” causing euphoria as well as flooding it with the chemical messenger dopamine. Many people don’t understand why or how other people become addicted to drugs. Share sensitive information only on official, secure websites.

Where can people get buprenorphine?

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. 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 Addiction Relapse Risks and outreach are key in helping people understand the possible risks of drug use.

What Is Addiction?

• It’s common for a person to relapse, but relapse doesn’t mean that treatment doesn’t work.
• Treatment enables people to counteract addiction’s disruptive effects on their brain and behavior and regain control of their lives.
• 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.
• Medications are also available to help treat addiction to alcohol and nicotine.
• Thomas Ross, staff scientist in the Neuroimaging Research Branch at the NIDA, uses brain imaging techniques such as…
• Those changes may last a long time after a person has stopped taking drugs.11

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.

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. This reduces the high that the person feels compared to the high they felt when first taking the drug—an effect known as tolerance. A properly functioning reward system motivates a person to repeat behaviors needed to thrive, such as eating and spending time with loved ones. As with other chronic health conditions, treatment should be ongoing and should be adjusted based on how the patient responds.

Introducing drugs during this period of development may cause brain changes that have profound and long-lasting consequences. The fact that this critical part of a teen’s brain is still a work in progress puts them at increased risk for trying drugs or continuing to take them. But drugs can quickly take over a person’s life. Those changes may last a long time after a person has stopped taking drugs.11 Addiction is defined as a chronic, relapsing disorder characterized by compulsive drug seeking and use despite adverse consequences.† It is considered a brain disorder, because it involves functional changes to brain circuits involved in reward, stress, and self-control.

How can addiction harm other people?

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.

Are medications for opioid use disorder safe to use during pregnancy and breastfeeding?

There is no need to visit special treatment clinics.9 Since the COVID-19 pandemic, health care providers can even prescribe buprenorphine via telehealth services, making it easier for people to get buprenorphine and stay in treatment.12 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.

What are the other health consequences of drug addiction?

There are FDA-approved medications that can help people stop or reduce opioid use. This booklet aims to fill that knowledge gap by providing scientific information about the disorder of drug addiction, including the many harmful consequences of drug use and the basic approaches that have been developed to prevent and treat substance use disorders. Today, thanks to science, our views and our responses to addiction and the broader spectrum of substance use disorders have changed dramatically. Those views shaped society’s responses to drug use, treating it as a moral failing rather than a health problem, which led to an emphasis on punishment rather than prevention and treatment. When scientists began to study addictive behavior in the 1930s, people with an addiction were thought to be morally flawed and lacking in willpower. For much of the past century, scientists studying drugs and drug use labored in the shadows of powerful myths and misconceptions about the nature of addiction.

If taking drugs makes people feel good or better, what’s the problem?

Learn about health effects, risks, and treatment options. Supporting scientific research on drug use and addiction Provides scientific information about the disease of drug addiction, including the many harmful consequences of drug… 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.

Several buprenorphine products are approved for treatment of opioid use disorder, including tablets that are placed under the tongue, extended-release injections, and implants. Buprenorphine also binds to and activates mu-opioid receptors in the brain, but to a lesser degree than methadone; it also can block other opioid drugs from attaching to those receptors. 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.

Drugs change the brain in ways that make quitting hard, even for those who want to.

What is opioid use disorder?

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.

Drugs, Brains, and Behavior: The Science of Addiction

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. In general, the more risk factors a person has, the greater the chance that taking drugs will lead to drug use and addiction.

What is drug addiction?

While relapse is a normal part of recovery, for some drugs, it can be very dangerous—even deadly. Treatment of chronic diseases involves changing deeply rooted behaviors, and relapse doesn’t mean treatment has failed. If people stop following their medical treatment plan, they are likely to relapse. Like treatment for other chronic diseases such as heart disease or asthma, addiction treatment is not a cure, but a way of managing the condition. Yes, addiction is a treatable disorder. One of the brain areas still maturing during adolescence is the prefrontal cortex—the part of the brain that allows people to assess situations, make sound decisions, and keep emotions and desires under control.

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.
