Sounds like you want them to be punished for the shit they're doing, not the fact that they're high or drunk. Troll picks and feeding have nothing to do with drugs and alcohol lol.
If you wanna make a case for smoking marijuana hindering gameplay, I'm gonna need some serious data to support that idea. And not some vague "it slows your reaction times" shit. There's more to the game than reaction times. Focus and stress can play a big factor and weed helps focus and relieves stress.
If you're in a good state of mind, your gameplay is affected in a positive way imo. And weed puts me in a pretty good state of mind. I don't play drunk... I think obviously being drunk hurts your gameplay, but weed is a bit more complicated IMO. I would never advocate or encourage people to smoke weed, I'm not like that, I'm not defending it just cuz I'm bias cuz I smoke it.. I'm just saying, being high honestly does not hinder my gameplay imo.
Then again, there are degrees to that. My friend does dabs and you can tell it spaces him out more and he gets a little slow lol. If I just get done choking down a blunt, then yeah I'm gonna be a little slow. But if I just smoke a bowl like usual after work, I'm fucking locked in dude. I'm focused and playing to the best of my ability. I was better at sc1 when I was high, and I think I'm better at league when I'm high. This may not be true, but I honestly can't say I play worse. May not be better, but it's not worse either. When I see people say "sorry I'm too high" I scoff and shake my head. They're just trying to sound like they have a cool excuse for sucking ass.
