Good question I think everyone would want to know the answer to. If your a true burner, maybe more like a month would benefit you. Tolerance usually doesnt change in a week. Exercise before you smoke, maybe workout at the gym, tennis, running, what have you. Then burn and without question you will be more elevated as opposed to not exercising and releasing endorphins naturally. Anyone ever notice after a workout or physical activity you feel smarter, your vocab is more readily available, etc? After tennis, my homeboys and I always smoke spliffs or J's right on the court, and I always feel peaked high afterwards. Hope that helps, cheerio!
