When I'm touring, I never smoke til I'm boutta drop or even out of a dangerous zone. I don't trust my baked self not to do something stupid and the risk is just way to high in avalanche conditions. For all mountain, I'll get absolutely ripped, and somehow don't get tired til I come down, so I'll usually toke again after lunch. I remember when I was maybe 15 or 16, and it was like my second time smoking, I got absolutely baked out of my mind and tried to ski park. Ended up absolutely mobbing full speed through the park like I was being chased, and sent every jump to the bottom (not the cool way). Luckily the big park wasn't open yet cause I would have fucking died. Did my first disaster that day too. These days, I usually just smoke a bowl in the morning or not at all and I'm fine for park. Pow while high is absolutely euphoric and I would recommend.
A question I have for NS: Does ski patrol care about smoking where you guys ski?
A lot of ski areas are in national forest, meaning it falls under federal jurisdiction, but its not like the DEA is posted up at Vail. I'm usually discrete about it and only use an extract pen on the lift which doesn't really smell and people just think you're vaping nic or something.
