Human culture involves learning to consume natural or synthetic psychoactive compounds that alter mental states and behavior. After a novel psychoactive substance (NPS) emerges and is experimentally used, its benefits and harms can be estimated, leading to legal classifications ranging from medical use to complete bans. However, banned drugs often continue to be used, allowing better understanding of their properties, and views on a drug can shift from harmful to medically useful. This review summarizes recent neuropharmacological progress on several NPS, including mitragynine, synthetic cannabinoids, dimethyltryptamine, novel serotonergic hallucinogens, cathinones, ketamine, novel dissociatives, gamma-hydroxybutyrate, gamma-butyrolactone, and 1,4-butanediol, highlighting both emerging harm potentials and potential medical applications.
