Methamphetamine HCl can be vaporized by itself. What is true for cocaine is not true for other drugs. Freebase methamphetamine is an oily liquid at normal temperatures. Almost all methamphetamine is the hydrochoride salt. It is what gives it the crystalline structure.
In my defense I haven’t really been involved with any of this in a decade and it’s entirely possible I mixed up cocaine and meth and their respective likelihoods of pyrolyzation in this case.
For some reason I remember a DEA Microgram bulletin showing crystalline dextromethamphetamine base in brick form, but it’s not available anymore and I can’t find it at the moment. I have had very few conversations with meth chemists over the years but I do distinctly remember the mention of the oily liquid in the latter stages when talking to them.
That being said, snorting meth (even HCl) is incredibly excruciating compared to other drugs and as a result most users that I’ve been around prefer to use it in a different manner.
