Bad trip

Unpleasant experience triggered by psychoactive drugs

A bad trip is a term describing an acute adverse psychological reaction to effects produced under the influence of psychoactive substances, namely psychedelics. There is no clear definition of what constitutes a bad trip. Additionally, knowledge on the cause of bad trips and who may be vulnerable to such experiences are limited. Existing studies report that possible adverse reactions include, anxiety, panic, depersonalization, ego dissolution, paranoia, as well as physiological symptoms such as dizziness and heart palpitations. However, most studies indicate that the set and setting of substance use influence how people respond.
