Classes of psychoactive drugs include stimulants, depressants, anxiolytics, euphoriants, hallucinogens, and empathogens, each affecting the brain's chemistry in different ways.
Addiction and dependence are significant risks associated with the misuse of psychoactive substances. These drugs have the potential to be rewarding and positively reinforcing, leading to patterns of compulsive use despite negative consequences. Rehabilitation for those with substance use disorders may involve psychotherapy and sometimes the use of other psychoactive substances on a temporary basis.
