Has major negative health effects if smoked or chewed, Possible dependence, accompanied by severe crash with depression as drug effects wear off, particularly if smoked or injected. 6 general classifications of psychoactive drugs: Stimulants: These drugs increase activity in the central nervous system and are used to treat conditions such as attention deficit hyperactivity disorder (ADHD) and narcolepsy.
