I just found out my Bf is slamming crystal meth he says he only does it once a day...and he's been lying to me about doing it for the last two months....he doesn't act the way most meth head I've experienced act he is fairly laid back and normal...he has been labeled as a non responder for other drugs could it be that this drug has the opposite effect on him than on other people? Just trying to understand this a little better so I can decide if I need to leave him or not :/
