when I was skating pools, I was usually drinking a lot of beer and whiskey. Really, ingesting all sorts of crap. Fear was less of an issue. I'd get pretty wasted and do some cool shit I wouldn't try otherwise. While it was fun for a minute, it's not sustainable. Other than getting some really killer hill bombs at the tail end of benders, skating street while drinking never really worked out. I haven't drank in about 8 years.
When I was coming up we'd be burning Ls and skating all over the place. Blunt level stoned was never a good thing for my skating. Like never. Unless it was a just right cross fade situation.
Now, I know the sweet spot of what I want to experience and get there. Most of the time, unless I'm get really trying, herb doesn't get me too high anymore. So if I take a candy or smoke a bowl to loosen the limbs, it's alright.
What I really like to do is take .2g fungus, .5mg THC, and go skate. Shit gets real loosey goosey and extra fun
I don't know how it effects other people though because I take at least .1g fungus every day
I've had some cool experiences skating after eating a slice or coming off some mics, but skating while peaking or anything isn't really what I'm trying to do.
