ELI5: Why is ibogaine, a substance known to aid fantastically in treating/curing drug addiction, illegal for medical use in the USA?
gpt
From Wikipedia:

>Ibogaine is classified as a Schedule I-controlled substance in the United States, and is not approved there for addiction treatment (or any other therapeutic use) because of its hallucinogenic, neurotoxic, and cardiovascular side effects, as well as the scarcity of safety and efficacy data in human subjects.

So basically, it has some pretty serious side effects, and there ~~are~~ aren't enough human studies to demonstrate that it's safe, or actually useful at treating specific illnesses/symptoms.
