Meth may be the most dangerous illegal drug substance on the market today. If not, it certainly is among the more dangerous substances, up there with heroin. I've never tried meth but have a close friend who is addicted and I've been trying to help him. His health has deteriorated and he exhibits all those terrible sores on his face and body. I've noticed how people look at him, plenty of odd stares everywhere he goes. Do you think users of meth are stigmatized more than other drug users?
