I have a friend who received ibogaine as a treatment, in mexico, for opiate addiction and it is not at all like your average hallucinogenic drug.
for starters, she had to go through cardiac tests before they would even administer the stuff because it can cause serious cardiac symptoms, up to and including death. Somebody in her group was kicked out because they had been using meth the week of the trip (no pun intended). They were telling them that even too much caffeine could increase their risk of cardiac symptoms.
Then the trip itself was like 48 hours and it wasn't a fun trip like acid or mushrooms. The few things she would tell me about were awful, and she still won't talk about most of it almost a decade after the fact.
Some drugs don't need to be caught up in federal approval but ibogaine is absolutely a drug that needs the red tape and all the pomp and circumstance of FDA approval.
But did it work?
as far as I know. She also had to do serious therapy and addiction recovery stuff, so it wasn't like she was magically cured of being addict simply by using ibogaine, in, case that is how my story came off.
