How do you know we're all white? Haha J/K....It's just young white ppl man and I don't know. It's not like anyone really gives a fuck how much you smoke unless you're smoking it with them.
I have friends that are black and they always brag about how many grams they stuffed in a blunt......
Also id like to add that alot of rappers brag about how much they deal/smoke.....dont stereotype like that its not cool to a lot of people. Unless of course you were joking but it doesnt seem like it, seems more like mockery.
