generally because the white kids are buyers, not dealers. they have a very small amount just for them, the dealers are dealing and have larger amounts.
a dealer is worse than a user. the dealer doesn’t give a sh1t about the people they sell that crap to. if it is detroying that person’s life or not. coke and meth and crack will eff up your life big time. that leads them into crime too, to keep their habit.
I hear you on the dealer/user point but there are a lot white kids who are “dealers” in pot and, admitted, less hard core drugs, in their suburban communities who aren’t getting the book thrown at them. I know a couple of them in my area. As I said, I don’t buy knee-jerk racism accusations, but I still think there is some truth to the idea that the poor and blacks are treated worse.
