Ecstasy, herbal ecstasy, rohypnol ("roofies"), GHB (gamma hydroxy-butyrate), and ketamine are among the drugs used by some teens and young adults as part of raves and trances. Recent research, however, is uncovering the serious damage that can occur in several parts of the brain from use of some of these drugs.
