I know anything smoked affects the lungs, but through experience, I'd say cannabis doesn't do much. When I was 15-17 in HS, I was at my peak of smoking. Sometimes a few times a week, sometimes everyday, sometimes multiple times a day...[also while drinking heavily and experimenting]. Still played basketball every year in HS as well as ran X-Country a few years among intramural sports. We ran anywhere from 3-8 miles a day in X-C, sometimes even smoking before, and noticed no drop off. If it hindered my performance, I would have stopped point blank. I still play sports all the time as well as work out.

Again like with the motivation thing, it's up to the individual to decide...the only person who will know is you.
