Tell ya what.. As others have said anything thats going to bump up your blood pressure is not good. On my last cycle I smoked some weed and then got up to use the john. My b/p had jumped up too high and I passed out. It was the first and last time that I smoke while juicing. I had a buddy who did a shitload of coke while on a cycle and he had a heart attack. Not worth it. Just juice and enjoy the results.
