Theres some liquid that police use to test if something has cocaine on it, or if a suspected substance is actually cocaine. Im pretty sure the liquid turns a blueish color when positive. The question is what is this substance they use?

It's called a "narco-pouch" I think.

Yeah my question is what is the chemical that makes up this "Cocaine Salts and Base Reagent", as they put it.

Hmm so i guess a regular marquis reagent can test for it, too bad it doesnt say that on the sites they sell them on cause i bought the mandalin one. Doesnt someone here sell em?

I recall Stupid Noob saying he is :)
