How Drug Addiction Affects the Brain and Body

Substances send massive surges of dopamine through your brain, too. But instead of feeling motivated to do the things you need to survive (eat, work and spend time with loved ones), such massive dopamine levels can lead to damaging changes that affect your thoughts, feelings and behavior. Tobacco use disorder is the most common substance use disorder worldwide and in the United States.

Effects of Drug Addiction on the Brain

However, there are very few objective and effective strategies for treating drug addiction. Without the mandatory mechanistic basic knowledge on drug addiction, the development of new therapeutic strategies is postponed. The arts can be used in a variety of ways to address issues related to addiction. Art can be used as a form of therapy in the treatment of substance use disorders. Creative activities like painting, sculpting, music, and writing can help people express their feelings and experiences in safe and healthy ways. The arts can be used as an assessment tool to identify underlying issues that may be contributing to a person’s substance use disorder.

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

Of course, drug use—either illegal or prescription—doesn’t automatically lead to abuse. Some people are able to use recreational or prescription drugs without experiencing negative effects, while others find that substance use takes a serious toll on their health and well-being. Similarly, there is no specific point at which drug use moves from casual to problematic. 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. When scientists began to study addictive behavior in the 1930s, people with an addiction were thought to be morally flawed and lacking in willpower. 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.

MEDICAL ENCYCLOPEDIA

Detox may involve gradually reducing the dose of the drug or temporarily substituting other substances, such as methadone, buprenorphine, or a combination of buprenorphine and naloxone. The goal of detoxification, also called “detox” or withdrawal therapy, is to enable you to stop taking the addicting drug as quickly and safely as possible. For some people, it may be safe to undergo withdrawal therapy on an outpatient basis. Others may need admission to a hospital or a residential treatment center.

What are the signs and symptoms of substance use disorder?

Usually, drug abuse starts with a ‘gateway’ drug (mostly socially driven) catapulting the individual vulnerability to other drugs of abuse [14]. Further studies showed that histone PTMs that occur in the NAc after chronic drug administration are locus specific [150, 190, 191]. Conversely, hundreds of genes show opposite or no changes in these same PTMs after drug exposure.

Prevention and Risk Factors

Tolerance happens when a dose of a substance becomes less effective over time. what is drug addiction isn’t about just heroin, cocaine, or other illegal drugs. You can get addicted to alcohol, nicotine, sleep and anti-anxiety medications, and other legal substances. 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. Although personal events and cultural factors affect drug use trends, when young people view drug use as harmful, they tend to decrease their drug taking.

  • They might take more of the drug to try and achieve the same high.
  • For example, withdrawal symptoms are not specified for inhalant use.
  • 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.
  • Diagnosing drug addiction (substance use disorder) requires a thorough evaluation and often includes an assessment by a psychiatrist, a psychologist, or a licensed alcohol and drug counselor.
  • If you are using drugs to fill a void in your life, you’re more at risk of crossing the line from casual drug use to drug abuse and addiction.
  • But with continued use, a person’s ability to exert self-control can become seriously impaired.

School programs like DARE represent a positive effort to curb drug use and experimentation. However, while education is most effective before the development of health problems, patient education has a place at any stage of addiction. Patients are more likely to reach and maintain abstinence and institute positive lifestyle changes if clinicians and other healthcare professionals engage in consistent and positive patient encouragement. For spouses and family members of those with substance use disorder, it may be vital that you get involved in a support group (such as Al-Anon) and seek help from a mental health professional as well. Examples of medications for substance use disorders include those that treat the various stages of recovery. There are specific ages that make a person more likely to develop a substance use problem.

The progression of drug addiction begins with the first exposure, mostly when the drug is taken voluntarily for its recreational and hedonic effect, and progressively consolidates during repeated but still controlled drug use. While administration intensifies along with loss of control over drug intake, drug use becomes habitual and compulsive in vulnerable individuals [4, 29, 30] (Fig. 2). 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. Treatment enables people to counteract addiction’s disruptive effects on their brain and behavior and regain control of their lives. It involves continued substance use despite negative consequences. Addiction to substances happens when the reward system in your brain “takes over” and amplifies compulsive substance-seeking.

For example, in 2011, Monsey et al. [196] elegantly demonstrated that DNA methylation and histone H3 acetylation regulate auditory fear conditioning and its related synaptic plasticity in the amygdala. Brain plasticity is a fascinating capacity allowing appropriate modification of the neural activity in response to new experiences and environmental stimuli [32]. Modifying the synaptic strength between neurons is widely assumed to be the mechanism by which memory is encoded and stored in the brain [7]. Hence, it is appealing to hypothesise that drugs of abuse cause long-term alterations on behaviour by changing synaptic plasticity in key brain circuits [4, 7, 32].

  • Treatment for drug addiction may involve psychotherapy, medication, hospitalization, support groups, or a combination.
  • If you are starting to think you might have an addiction, you have probably moved into the contemplation stage.
