Good question, vicka - I do not know...to my uncertain
knowledge 'they' do not use noribogaine. If I am not mistaken, 'they' are fiddling around with these analogues - the most 'promising' of which seems to be 18 MC (18, Methoxycoronaridine) Glick and his associates are pioneering this research, and I know little of it save the name and a few weak articles I have found online. I think (think, mind you) that these compounds are being explored for their efficacy in addiction interruption, as a 'replacement' for the naturally occurring ibogamines.
See - http://en.wikipedia.org/wiki/18-Methoxycoronaridine
This can be looked at in two ways: what 'they' say is that they are looking for analogues to substitute the ibogaine - a compound which will have all the healing elements of the ibogamines without
the psychedelic or oneirogenic effects, and of course, they are touting 'safety' as a key motivator - suggesting by contrast that these new synthetics will be safer, more manageable for the patient, etc...this to me ignores the most powerful aspects of the ibogoids in the first place - the psychological catharsis brought on by its unique psychotropic effects. They will not succeed in perfecting that which already IS.
The other way to look at, of which I am partial, is the cynical route: you can patent all these synthetics and if they can formulate even ONE that approaches the anti addictive properties of ibogaine, sans the 'disturbing psychological elements' - then we may well see something on the market.
For now though, we are safe - unless I have missed updated data, human trails are not yet underway, at least not in any significant fashion.
These psychological effects that scientists are trying to eliminate or at least mitigate are the very tool and prime instrument in these processes - but if you can de-fang something like this, there will be a much broader market and Big Pharma will have a new cash cow to sell to all their Suboxone junkies.
Forgive the atmosphere of abrasion, I get piffed when I think of all the REAL work that is so often overlooked for reasons of , IMHO, poor ethics disguised as medicine...
The Medicine is HERE, Now.
As for noribogaine, I think the full spectrum or total-alkaloid extracts contain more of this by weight than isolated ibogaine hcl, nor ibogaine being one of the alks already present in the profile - thus it need not be converted by the liver as does ibogaine. Couple the presence of both ibogaine AND nor ibogaine in the TA and it is a more powerful elixir with the additional properties.
