Indeed - in the UK H was seen as a 'dirty white man's drug' and so those of African and West Indian heritage stuck to stone. Of course, after a few weeks licking on a pipe, they were psychotic wrecks and so H became the usual 'come down' drug. But it then meant that a whole community that had never seen the damage H causes suddenly see an influx.
At the opposite side of the spectrum, those of a European background and who were well into their brown would end up at the point where H didn't produce a rush and nothing much of a high. So in the 1980s powder code + H ended up in the same pin as a speedball. Since crack arrived, those people are salting their crack so it's fit to bang up.
The result is the same no matter where you start. A massive habit and an overwhelming desire to add cocaine to the hits so that they DO produce a rush....
My friend Michael Linnell produced this funny and informative cartoon on the subject. And all of it is based on what ex-users tell him so it's pretty much spot on. If you smoke stone,
I hope someone finds it of interest.

I am not judging anyone, but often it seems a waste when people who have a way out swap it all for speedballs.
