The document discusses several drugs including heroin, ecstasy/molly, steroids, cocaine, and marijuana. Heroin is highly addictive and can be injected, snorted or smoked, with health risks including overdose and infections. Ecstasy increases heart rate and blood pressure and causes side effects like nausea. Steroids are often abused at much higher doses than prescribed, with side effects of mood issues and behavior changes. Cocaine can be snorted, injected or smoked and some forms like crack are crystalline. Marijuana cannot cause overdose but many people have been arrested for possession.
