Cocaine and adulterants

Posted by in Doctor X files, Other drug question

 

I happened to eat a pair of lines of coke. They tasted a whole lot like caffeine.

I don’t have much experience with coke, but I think I can tell that it did contain real cocaine by how it anesthetized my tongue. But I know caffeine really well, and that tasted a lot like it. Is that normal for cocaine? Do all extracted crystalline alkaloids taste like that?

 

An anesthetic effect is not indicative of cocaine purity. Other local anaesthetics (lidocaine, benzocaine, tetracaine…) produce this effect and these are common adulterants of cocaine (exactly for that reason). Scott test (cobalt thiocyanate reagent) is the easiest way to distinguish between cocaine and other local anaesthetics. It is impossible to estimate cocaine purity by taste.
