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. In reality, drug addiction is a complex disease, and quitting usually takes more than good intentions or a strong will. Drugs change the brain in ways that make quitting hard, even for those who want to. 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. Read the DrugFacts.

Nora D. George F. George Koob. This guide, intended for parents, practitioners, and policymakers, begins with a list of 7 principles addressing the specific ways in which early interventions can have positive effects on development; these principles reflect findings on the influence of intervening early with vulnerable populations, on the course of child development, and on common elements of early childhood programs. March The third in a 5-part series, reviews the science behind drug abuse and addiction and introduces the topics of prevention and treatment. February Equips teachers and students in grades 9 through 12 with interactive curriculum on the neurobiology of the brain as a result of drug abuse and addiction.

The fifth in a 5-part series, summarizes the science behind drug abuse and addiction, reviews the harmful consequences of drug use, and poses the question of whether it is worth the risk. January The fourth in a 5-part series, explores the biology behind ecstasy use in the brain and discusses both short- and long-term effects of its use.

Before approaching someone you think may have an addition, determine if the problem is a result of a single incident or a growing problem with the addiction. If you or someone you know has an addiction, call for free and confidential treatment referral and information from SAMHSA. You can also seek help from your doctor, local treatment center, or support group. The most effective treatments are comprehensive.

They often have several steps that vary from person to person. These steps can include detoxification, behavioral counseling, and long-term follow-up. While you can treat addiction, in most cases, someone with addiction must want to change for recovery to be successful. Science continues to grapple with this answer.

Explaining Addiction

Some people may experiment with a substance and never use it again. Others may experiment with the same substance and begin the addictive process. Current research suggests there may be a genetic component to addictive disorders, but more research needs to be done.
