Pyridine is listed as a cat#1 chemical on the Code of Practice for Supply Diversion into Illicit Drug Manufacture. To order it you must be an account holder with the supply company and fill out an End User Declaration (EUD) form.
Pyridine has one of the most awful smells IMO and even a sealed bottle often stinks. Open the top and all nearby will smell it.
Pyridine is used along with another cat # 1 chemical in the manufacture of heroin.
I wasnt planning on making any drugs, I was just reading about how the kiwi's get their smack.
I read that on one island of NZ cant remember but on island has liquid heroin ranging from clear to an unhealthy looking "soy sauce" like liquid, the other has standard powder, but it is all homebake, thats crazy IMO.
