Ibogaine and noribogaine, psychedelic substances from plants of the Apocynaceae family, show some efficacy in treating substance use disorders, particularly opiate detoxification. However, their use carries concerning risks of cardiotoxicity and mortality. A meta-analysis of side effects found a significant risk of developing headaches after treatment. The evidence, drawn from case reports, randomized controlled trials, open-label studies, surveys, and observational studies, remains unclear on overall efficacy and toxicity. Further research is needed to evaluate therapeutic benefits and safety.

Synthetic cannabinoids are the novel psychoactive substances most strongly associated with acute psychosis and, in some cases, persistent or relapsing psychotic disorders. Some cases show symptoms overlapping with schizophrenia, suggesting a possible risk of transition to chronic illness. Synthetic cathinones and phenethylamines are also linked to psychotic manifestations including thought disturbances and perceptual abnormalities. While many psychotic episodes are transient, a notable proportion evolve into persistent states, indicating that these substances may unmask latent vulnerabilities or directly contribute to chronic psychotic disorders. Clinicians should systematically assess NPS use in first-episode psychosis patients.

Piperazines, synthetic compounds with stimulant and hallucinogenic effects, are linked to acute psychotic episodes. A systematic review of 4 studies found that piperazine abuse frequently triggers symptoms such as paranoia, auditory, and visual hallucinations. The compounds' complex polyreceptor action may explain these effects, similar to other novel psychoactive substances. Recovery is common after cessation and treatment, but data on long-term outcomes are limited. Further research into piperazine abuse and specific treatment protocols for substance-induced psychosis is needed.

Abusing certain over-the-counter medications can trigger psychotic symptoms such as paranoia, hallucinations, and thought disorders. Antihistamines, dextromethorphan, and other OTC drugs are implicated. Dextromethorphan misuse is especially linked to chronic psychosis, while other substances more often cause acute substance-induced psychosis. The review analyzed 46 relevant studies from an initial pool of 2,677 articles, highlighting the need for greater awareness and interventions to address OTC drug misuse and its psychiatric consequences.
