ya man i smoke and play hockey all the time. I find when i'm high i can actually get into the game more like not that i take it more seriously but i just seem to be so damn focused on scoring i play better. If u just toke weed and not cigs you should be fine. I've only smoked weed during my life and i wouldn't say my stanima is that bad. I smoke a solid 3 grams a day so you should be fine.
