Drug Misuse and Addiction National Institute on Drug Abuse NIDA
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. Therefore, education and outreach are key in helping people understand the possible risks of drug use.
In its simplest form, drug addiction can be seen as a way of hacking the brain—of finding a shortcut to feelings of emotional reward by bypassing the normal activities that stimulate such sensations and directly manipulating the neurochemicals responsible for them. To a very large degree, brain hacks become appealing when there are restricted opportunities for meaning and for pleasure other than the response to drugs. There are no substances (or activities) that universally or uniformly cause people to become addicted. And the vast majority of people exposed to most substances (or activities) considered addictive do not in fact develop addiction to them.
- Sometimes people quit their drug use for a while because they’re away from triggers that remind them about their drug 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.
- The addicting drug causes physical changes to some nerve cells (neurons) in your brain.
- Other models of addiction emphasize the role that social and economic factors play in shaping behavior, such as the strength of family and peer relationships and the presence of absence of educational and employment opportunities.
Why do some people become addicted to drugs, while others do not?
The talking points below are written in plain language as a suggested way to communicate concepts of drug use and addiction to adults or teens. You’ll soon start receiving the latest Mayo Clinic health information you requested in your inbox. Signs and symptoms of drug use or intoxication may vary, depending on the type of drug. Many people are caught in a vicious cycle of using alcohol or cannabis to fall asleep and then nicotine, caffeine, and sugar to be more alert.

Cocaine processed so that it can be smoked, it enters the blood stream rapidly and produces a rapid “rush” of a high; the immediate response becomes powerfully reinforcing, driving the motivation to repeat the experience.
What is drug addiction?
The repetition of a highly pleasurable experience—drugs, gambling—alters neurons; they adjust their wiring to become increasingly efficient at the experience. As drug use stops, engaging in other rewarding activities rewires the brain to find interest and pleasure in non-drug pursuits. However, there are a number of personality traits, each of which is partly genetically influenced, is salvia deadly that contribute to the risk of addiction.

Biological factors such as enzyme profile can influence the amount of alcohol people ingest, the pleasantness of the experience, harmful effects on the body, and the development of disease. 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. 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. Introducing drugs during this period of development may cause brain changes that have profound and long-lasting consequences. Many people don’t understand why or how other liberty cap gills people become addicted to drugs.
Risk and protective factors may be either environmental or biological. Given that this is the first article to apply the PERMA model to substance use, several viable future directions exist. Researchers may consider developing and validating a multidimensional scale of the PERMA model specifically for substance use. Further, it remains unclear if a treatment package designed to target the components of the PERMA model for substance use disorders would be effective or efficacious. Finally, more literature support for the PERMA model for substance use disorders may be beneficial, as this paper was limited in the depth of its literature review due to the paper format.
The effects of drugs are pleasurable and rewarding only in relation to how a person feels emotionally and physically in the context of his or her relationships and social life and other opportunities for development and reward. Certain people are at risk for substance abuse and for developing addiction disorders. Their vulnerability might originate from a variety of factors, including their genetic endowment, family background, psychological factors, and social norms. Overall, these factors make harbor house sober living the person value drug use highly, even though the decision might be against their long-term interests. Please note that a risk factor for one person may not be the same for another. Meaning in the PERMA framework refers to the sense of purpose in one’s life and the coherency of events that the person experiences (Seligman, 2011).
People recovering from addiction often have one or more relapses along the way if they don’t take steps to avoid their triggers. Drug addiction can start with experimental use of a recreational drug in social situations, and, for some people, the drug use becomes more frequent. For others, particularly with opioids, drug addiction begins when they take prescribed medicines or receive them from others who have prescriptions. There is some evidence that natural variation in genetic makeup of the dopamine system may influence who gets addicted. Dopamine is the neurotransmitter activated by rewarding activities as a way of increasing the likelihood of engaging in such activities in the future. Having a relationship, getting a promotion, doing something creative—those are normal ways of stimulating the reward system.
One use of a substance can produce a pleasurable effect that motivates interest in repeating the experience. But the experience of pleasure is relative; it hinges in part on biology and very much on what else there is going on in a persons life that is meaningful or rewarding. Adverse childhood experiences (ACEs) such as trauma, especially combined with an unpredictable and chaotic childhood, pose a risk factor for many kinds of maladaptive behaviors and poor health outcomes. Studies show that having multiple ACEs puts children at risk of poor school performance, unemployment, and high-risk health behaviors including smoking and drug use. As a person continues to use drugs, the brain adapts by reducing the ability of cells in the reward circuit to respond to it.
Drug addiction, also called substance use disorder, is a disease that affects a person’s brain and behavior and leads to an inability to control the use of a legal or illegal drug or medicine. Substances such as alcohol, marijuana and nicotine also are considered drugs. When you’re addicted, you may continue using the drug despite the harm it causes.
