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.
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.
