The purpose of Ibogaine that Ameen was recommending is opiate addiction. Andy probably got addicted opiate pain killers and wanted to kick the addiction.
Ameen would not buy or provide the Ibogaine, but he would assist in administering it. He charged $20K for his services.
I remember Leo saying Ameen would buy Ibogaine off some well known vendor on the net. He spent a hundred bucks and then sold it to desperate addicts for 2 or 3K. Something like that. Ameen said only he had the real high quality stuff but it was all bullshit.
If I'm not mistaken Ameen adviced that guy with the huge belly, forgot his name, on Ibogaine. I remember guys on the net were very critical since the guy had all the contraindications for taking a drug like this. Now I remember the name, Lenny. But he apparently survived.
I've read that an Ibogaine trip is absolute horror, a real nightmare. I don't know if I'd dare to take it even if I "needed" it. And apparently it doesn't work that well. Leo said Ameen is still an addict. He takes ibogaine when he needs to stay clean for a couple of days, like when traveling.
