This is terrible news, but perhaps not that unexpected. There seems to be numerous companies in central Africa offering vast quantities of pure ibogaine and iboga alkaloids and root bark, with the purer extracts being much more expensive...there is potential for massive profit margins to be made off iboga in this way, and if such a thing can be exploited, it will be. It is very regrettable but people will just try and make a living by any way they can. Due to the complexity and cost of synthesising iboga alkaloids, all the pressure is on the plants to provide.
A few of the Bwiti grow their own iboga and its sometimes grown outside the Bwiti temples for ceremonies. Part of the ritual though is to go into the wild and harvest the roots, in a similar way that the Huichol utilise Peyote. I think it would be certainly possible to farm iboga sustainably, in a similar way that caapi is in some areas of Amazonia. I think iboga would wish to continue working with people if that makes sense, so it is up to us to take care of it...for what it gives us it is the very least we can do. To lose this plant would be to lose something very special forever. Still though, if iboga's destiny is to become a private commodity in order to survive into the future, I fear those who will lose most are the Bwiti themselves.
If people do plan on obtaining iboga, it is important to ask how their vendor of choice obtained their stocks of iboga. Remember that iboga is a plant from the western part of central Africa...Gabon is its spiritual home but it also grows wild in Cameroon and the Congo. I know for a fact that none of the iboga I have ingested has been of Gabonese origin. If I lived in the tropics I would definitely be growing some.
