Not to derail the discussion, but does meth scare the shit out of anyone else? Seriously, I think I fear meth more than heroin.
Not a fun situation. I think the advice given here for the most part is pretty spot on. If he starts threatening you then you should probably go to the cops. If not, just stay away from them. Thats what i'd do. I've had some somewhat similar situations. Doesn't scare me, but its the only drug I didn't try/won't try. I feel really bad for meth addicts though, as I know what its like to be an addict. God Bless 'em, man. The scary part I suppose is the fact that its pretty widespread in this country, and meth labs are pretty dangerous. What is really scary is meth cookers who have children in the house, that pisses me off.
