I know kids that used to get high alllll the time before the worked out. I think it just depends on the person and whether or not your used to working out high. As for how it effects you physically, i'm almost positive that smoking opens up your bronchial tubes in your lungs making it easier to breath i guess, or maybe it makes more oxygen go to your body? anyway, i dont think that it is bad for you to smoke and workout, but for people who get motivated to workout when they smoke, more power to you. I cant do it and i lift religiously. theres my :twocents:
