But this doesn't apply to a phenathylamine like mescaline does it Dwayne? Obviously you can use citric acid when preparing a cactus based drink.
Well I suppose it might not, Ismene... by the way, do you go scouring the web day and night for posts to attempt to prove wrong? You obviously LOVE doing so, or aggressively attempting such at least.
Anyway, I know it applies to amphetamines (again, this is warned about in pharmacological guidelines and "patient information" pamphlets for them) and methylone for sure also (according to experiments by myself and many others), and according to the pharmacology research it should apply in general to all phenethylamines.
But of course, Ismene, it also would depend on total number of moles of acidifying substance consumed with the phen. It's not a "deactivating" effect on the phenethylamine itself, which you are apparently thinking indicating you totally misunderstand.
Rather the acid affects
the way that the digestive system processes the phenethylamine, the more acid the higher the inhibition. So in an acid-based extraction of mescaline, normally, the final steps are either boiling it way down to a concentrate which may well degrade the acid, or basify the solution by long boiling with other plant material when all is said and done... Or if you are talking about a complete "extraction" all the way to alkaloid/mescaline crystals I would think by this end stage there isn't much acid left, hence the effect would not apply, Ismene. Capice?
