A novel web-crawling tool called NPS.Finder® identified several thousand new psychoactive substances (NPS)—roughly four times more than European and international drug agencies report. Synthetic cannabinoids, new synthetic opioids, ketamine-like dissociatives, novel stimulants, novel psychedelics, and certain prescription and over-the-counter medicines were most commonly linked to psychopathological consequences. The rapid proliferation of recreational psychotropics poses a challenge for psychiatry because the pharmacodynamics and pharmacokinetics of many NPS remain poorly understood. Health and mental health professionals need up-to-date information on the range of NPS, their intake methods, sought-after effects, drug combinations, and associated medical and psychopathological risks.

Several new psychoactive substances (NPS) can trigger serotonin syndrome, a dangerous condition of excessive serotonin activity marked by altered mental status, neuromuscular effects, and autonomic hyperactivity. A systematic review of three retrospective studies, two case series, and five case reports identified implicated substances including psychedelic phenethylamines (2C-I, 25I-NBOMe, 5-IT) and synthetic cathinones (mephedrone, MDPV, methylone, butylone, NRG3, AMT, MXP), as well as the antidepressant bupropion when misused at high doses or combined with other serotonergic drugs. Most substances were taken orally, though nasal insufflation and sublingual administration occurred. Psychiatric history was negative for most subjects. Clinicians should recognize NPS risks and diagnostic challenges due to undetectability in routine drug screenings.

Clinicians need regular updates on novel psychoactive substances (NPS) and their acute and long-term medical, psychobiological, and psychopathological risks. Future research should combine pro-drug website analysis with computational chemistry to organize preclinical studies of new psychoactives. Psychedelic research should develop robust study designs to assess potential therapeutic benefits, as these molecules likely have limited dependence liability.
