Personally, I think food tastes a lot better after a smoke. I mean, I hate Andy Capp's hot fries, but for some reason, after a smoke, it's like they're the best thing I've ever put in my mouth. And grilled cheese... I'm not sure that I lose weight, but I'll bet it's like tobacco smoking. If you're hands and mouth are busy smoking, then you're not stuffing your face at that moment. If you can beat the munchies, then maybe... Usually huge weight lose is associated with damaging drugs like meth and cocaine (I have yet to be damaged by mj )
