It is available in all larger urban areas, but is not common. You need to be pretty well connected to get it.
Boiling point is very low.
You can smoke it by placing about 10 mg on aluminum foil, and holding a lighter under the foil to warm it. It vaporizes into a white cloud, and you suck the smoke through a tube or something to help catch all the smoke. It comes in a white powder, and looks similar to good white heroin. I think it would be hard to aldulterate, unless you adulterated it with something that also vaporized very easily. Ie, if you aldulterated it with sugar, the Aminorex would evaporate first, then the sugar would just burn, and you would be aware that you got burned.
