Chinky I take it you are a new smoker. One time I smoked some pot laced with meth. Ok yeah I did meth once. Not on my own free will might I add. But the guy rolled the joint before I got there. And assumed because everyone here does meth that I would too. But later I knew the buzz was different I asked him and he told me. Needless to say I never smoked with him again. The point is most people will not lace it. And no your inhaler won't hurt you if you use it after smoking. Actually I don't know any drug or chemical that has a negative reaction to marijuana. Alcohol mixed with MJ will make you a little more sleepy. It does me anyway. Or pain pills make you more relaxed. But that's all I can think of.
