Interesting article, if a little "tin-foil"-ish. My guess is that the stuff was researched, but that the risks outweighed the benefits.
On the other hand, for a hard-core junkie who really wants to quit, and is willing to take a risk, why not? (All assuming this stuff actually works.)
If there was a permanent cure for drug and alcohol addiction, every government on Earth would leap for it. Considering the costs of addiction, I'm surprised no one has found one by now. I'm skeptical ibogaine is the Wonder Drug some have touted it.
