A systematic review of 54 studies found that the intensity of the acute psychedelic experience, particularly mystical-type experiences, is the most frequently reported predictor of therapeutic response in psychedelic-assisted therapy for mental disorders, though this was not consistent across all disorders or time points. Factors related to set, setting, and dose were associated with the likelihood and intensity of these experiences. The review included adult populations with substance-use disorders, major depressive disorder, anxiety disorders, obsessive-compulsive disorder, post-traumatic stress disorder, and existential distress, as well as naturalistic samples.

Party drugs are a diverse group of legal and illegal psychoactive substances used in social settings like clubs and festivals to alter mood, perception, and social interaction. Alcohol and cannabis are most common, followed by amphetamine, MDMA, cocaine, and ketamine. These drugs act through various pharmacological mechanisms: alcohol affects GABAergic, glutamatergic, and dopaminergic systems; cannabis acts on the endocannabinoid system; stimulants increase monoaminergic neurotransmitters; MDMA has a strong serotonergic component; ketamine produces dissociative effects via glutamatergic mechanisms; and psychedelics alter sensory processing through serotonergic modulation. Polydrug use is frequent. Acute risks include cardiovascular strain, hyperthermia, and anxiety, while long-term consequences can involve cognitive impairments, dependence, and social complications.
