I personally, don't mind people smoking weed, don't care really, it's whatever to me, I don't personally do it.
But why do people see the need to get off their tits high, and then play competitive games like DotA, or even on WoW, why do people do it, it literally just makes them worthless to the team and to the enjoyment of the game to everyone else that's not stoned.
For reference, I just solo queued into 4 people together in DotA 2, who were all stoned off their faces, and because they've queued as a 4man, we get put up against a 5man premade, except, I don't have a team that's worth anything.
