^ The thing is, I think some people think that they only have to take ibogaine and any addiction will be banished. As with anything in life worth having, you have to be prepared to put a fair bit effort in yourself to get something worthwhile as a result. Don't know about setting quatiative values on how each contributes to the final result, but I wholeheartedly agree with tobala in that the actual pharmacological action of ibogaine is only a part of the whole shooting match, it also requires determination to free oneself from chemical enslavement. If you're just going through the whole thing so that your tlerance is reset back to zero, but then you will consider using again, then of course it's not going to work.
What I'm saying is that if we were to really thoroughly compare some pure, isolated Ibogaine converted from say T. Orientalis or Voacanga Africana, then I doubt this material is going to be found as effacious in treating addicts as Ibogaine extracted from T. Iboga root bark! It just will have a different plant teacher element... and from what I have gathered, the effects from this purified Ibogaine extract from Orientalis are COMPLETELY different from anything I have heard of with Ibogaine from T. Iboga!
That is open to scrutiny on several points as far as I can see;
1) How purified are these extracts? Just that separating the iboga alkaloids is a long drawn out process & not something that practically achievable with 'kitchen chemistry' equipment, but requires a serious column chromatography setup to isolate a usable dose of ibogaine. Without such adherance to the separation process then the ibogaine is not going to be pure, but containing asignificant proportion of closely related alkaloids (and after conversion of the ibogaine precursor from V. africana by decarboxylation, you're not going to have the same minor alkaloids present, or in similar ratios as the extract from T. iboga. As such, it's not going to be a surprise that they are subjectively different anymore than finding that san pedro alkaloid extract is subjectively different to the alkaloidal extrac from peyote.
2) Just a quick look at the structure of ibogaine looks like there are going to be chiral centres in the molecule and while decarboxylation of the alkaloid from V. africana might result in a compound that has the same empirical formula as ibogaine, that in no way means that they'll have the same pharmacological response (as a quick example, unless drawn using a 3D representation of the arrangement around the chiral carbon atom, the dextro isomer of methamphetamine or MDA looks the same identical to the laevo isomer of meth or MDA respectively, yet because of that chirality, they are subjectively very different from each other.
I know we've had a similar disagreement about such things regarding synthetic/extracted DMT, but again, if the compound is ostensibly pure (eg greater than say 99.5 percent pure by assay) and has an identical absolute configuration about any chiral centres, then they are going to have identical effects, regardless of their original source. If this weren't the case, then pharmacology (esp molecular pharmacology, determination of pharmacophores, modelling of receptor sites, would be pointless as there would be no rational basis to it. As far as I'm aware, there is no evidence to support the idea that the identical molecule from different sources has differing effects ie ibogaine is ibogaine, regardless of its origin
