Alcohol

Alcohol is one of the most widely used drugs in the world, and because it is legal for adults in many places, it is often viewed as harmless. In reality, alcohol is a psychoactive drug that affects how the brain works. It slows reaction time, impairs judgment, and reduces coordination.

For teens and young people, alcohol is especially harmful. The brain continues developing into the mid-20s. Drinking during this period can interfere with brain growth, affecting memory, learning, decision-making, and emotional control. Teens who drink are more likely to experience accidents, injuries, risky behavior, academic problems, and mental health issues.

Alcohol carries serious risks for all ages. Regular or heavy use can lead to addiction, liver disease, heart problems, and increased risk of certain cancers. Because alcohol is socially accepted and heavily advertised, its dangers are often underestimated.

Understanding alcohol as a drug—not just a drink—helps people make more informed and healthier choices.
