I have heard that it is not as inexpensive as I thought, like not cheaper than HCL from Iboga bark and there are wholesale suppliers.
Was not aware of anti-addiction properties of voacanga, and I see there are. Very Interesting. It seems that at the same level of grams of raw bark, iboga is 'stronger'.
Do not see any experience reports using extracted voacangine either, that would also be interesting.
Mushrooms I have recently heard can be great as well, at least for alcohol.
