I'm reviving this thread since I can't find any useful info about this anywhere. I have just the same question as OP, what all drugs can be vaporized?
Guess it also relies heavily on what type of vaporizer, I have a very good table vaporizer, don't remember name unfortunately, but it cost about 400$ and you can set exact temperature. I'm curious whether I could just scatter things like powder cocaine or other stim RCs in it. Start with low temperature if I don't know melting point, and slowly increase it until it starts to have effect. Probably these drugs are destroyed before actually vaporized? Someone must have tried it!
Please don't tell me to use crack pipe, inhaling from foils etc. since that is not vaporizing. That's smoking, which I never want to do again.
