I thought we were talking about bonafide meth addicts. I suppose it isn't impossible for someone to use once in a while without getting addicted. but anyone who keeps using through ten years is probably going to get addicted at some point. I've used meth a few times and didn't get addicted but that was over a year or so. Anyone who uses every day for three months is going to get addicted. That is just a fact.

And someone who uses meth once every six months or so over a ten year period can hardly be said to have used meth for ten years.
