Who is at risk for drug addiction?

Anyone can develop a substance use disorder. No one thing can predict whether a person may develop an addiction. You may be more prone to drug use due to:

Biology: The person’s genetic makeup, gender, ethnicity, and mental health issues may raise his or her risk for developing an addiction. About two-thirds of people in addiction treatment are men. Particular ethnicities are at higher risk for substance use disorder. This is true for Native Americans.
Environment: Surroundings can affect the likelihood of developing a substance use disorder. For example, stress, peer pressure, physical or sexual abuse, and early exposure to drugs can raise the risk.
Age: Teenagers who start taking drugs are especially at risk. The parts of the brain that control judgment, decisions, and self-control are not fully developed. Teens are more likely to engage in risky behaviors. In a developing brain, drugs can cause changes that make addiction more likely.

Can drug use and addiction be prevented?

Drug use and addiction are preventable. Prevention programs involving families, schools, communities, and the media may prevent or reduce drug use and addiction. These programs include education and outreach to help people understand the risks of drug use.


Medicinal advances and progress in diagnosis have helped the medical community develop various ways to manage and resolve additional trusted Sources.

Some methods include:

medication-based treatment
behavioral therapy and counseling
medical devices to treat withdrawal
treating related psychological factors, such as depression
ongoing care to reduce the risk of relapse

Addiction treatment is highly personalized and often requires the support of the individual’s community or family.

Treatment can take a long time and maybe complicated. Addiction is a chronic condition with a range of psychological and physical effects. Each substance or behavior may require different management techniques.
