Tobacco? that's odd, I can understand it if you're smoking weed, because weed is a mild hallucinagin(sp?), but if you're feeling weird off of tobacco, I'd say you're having a reaction from it. I'd imagine that's a bad thing. Unless it really bugs you out, and makes you uncomfertable, I would stop it. But if you don't mind the feeling then you probably have nothing to worry about. go with your guy feeling on it.
