Hey I was wondering if anyone could elaborate on this....I've been using meth for about 8 years now, mainly in the past 3 years I've noticed that some stuff that's not good makes my head feel warm, like my ears and face get red.(flushing) it's super annoying. I would assume that it is something that was used in the process, or something that was not purged off in the end, mabey I'm allergic to a certain compound. Can anyone explain what that is and is there a way to clean it?
