While using drugs, people are also less able to perform well in school, sports, and other activities. It's often harder to think clearly and make good decisions.
It can damage the brain and body, sometimes permanently. It can harm people around you, including friends, family members, children, and unborn babies. Drug use can also cause addiction. Many people don't understand why or how other people become addicted to drugs.
They may mistakenly think that those who use drugs lack moral principles or willpower and that they could stop using drugs simply by choosing to do so. In reality, drug addiction is a complex illness, and quitting smoking generally requires more than good intentions or a strong will.

Fortunately, researchers know more than ever how drugs affect the brain and have found treatments that can help people recover from drug addiction and lead productive lives.
