Given that some people are already working on a version that does not have the halluciagenic properties, I would assume that the descendent of ibogaine would be readily available for purchase (

) and easily made assuming that the person has access to the iboga plant.
Now, the interesting part would be what happens to the iboga plant during the Awakening. Given that it has halluciagenic properties now, what if it is the source of deepweed?
Seriously though, I would think that drug addictions could easily be cured but where is the profit in that? Your hypothetical character could make it and distribute and would gain a positive rep with those that want out of addiction, their families, employers, etc. However, you would be in deep with organized crime as you are drying up a revenue source. The degree to which they get upset would be directly proportional to your success and to the area to affected.
