Lately I've been getting a rash under my arms and it seems to be connected to using methamphetamine. It's a really sore red rash that ends up in all the skin peeling and is really sore. I've been wondering if it's connected to using certain deodorants but it only happens when I smoke ice. Last week though when I smoked pure, washed shit, it didn't happen, which leads me to think it's a certain cutter causing it. I know it's a bit of a long shot but has anyone experienced anything like this before, or happen to know of any meth cutters that could cause this...?
