Yes. I believe it was do to who uses it. Which is mosly black people. Because its much cheaper than coke, and they tend to be a lot poorer than white people.
Crack provides a more immediate high and is more dangerous because the high tends to happen faster. It is easier to overdose.
That might be true but another argument is that crack heads tend to become addicted much faster and are more violent crack_powder2002.pdf
I think the reason more blacks use crack instead of blow is way deeper than skin color. I think it has to do with city drug culture. Crack is easier to store, conceal, measure, and trade than a powder. That makes crack easier to sell on the street corners. You don't even need a bunch of baggies or a scale. Just cook a cake up on your stovetop, break a piece off, stick it in your shirt pocket, and hit the street corners. Crack isn't really cheaper than cocaine. that's how come people make it . It's just easily divisible.
