Substance Use

Common Drugs

​​​​​​​​​A drug is any substance that changes the way a person thinks, feels, or behaves. Legal drugs like alcohol and tobacco are commonly used. Many people take prescription drugs like painkillers, sleeping pills, and anti-depressants under a doctor's supervision. However, many prescription drugs are misused.

Misusing drugs and using illegal drugs like​ cocaine, LSD, amphetamines, and heroin can cause problems in people’s lives. Drug use can also affect their health and relationships. Many people lose their jobs or have money problems.
