"Finding an inexpensive, naturally occurring way to wean people off of heroin and prescription opiates without serious withdrawal symptoms would be a silver bullet for public health—and a gold mine for any entrepreneurs who discovered it."
It's already been discovered. Ibogaine is an extract of the African iboga bush (http://en.wikipedia.org/wiki/Ibogaine
