Ahh, nothing like some prejudicial stereotypes to show your closed-minded, ignorance.
So many people have been brainwashed into believing that anyone who touches this "evil" drug automatically become monsters...no middle ground of course. As soon as you use it, you become a horrible parent, a violent criminal, a raper of women, an unproductive member of society. Wait, does any of this shit sound familiar? It's the same crap that the government and people like you have spewed for nearly a century in efforts to criminalize a number of drugs...first marijuana, then heroin, lsd, cocaine, meth, etc.
Do you really believe it is impossible to use meth responsibly? The drug doesn't do evil shit...just some people who do evil shit happen to use meth. And if they didn't have meth available to them they'd probably be out shoving cocaine up their nose or binge drinking all night. These are addictions problems and often manifest themselves with whichever drug is available to them.
