It's really hard to get a hold of even mediocre cocaine hcl where I am, on the other hand, it's relatively easier to find good quality crack. Also good quality cocaine is very expensive; crack is much cheaper in comparison.
If O.P. is in a situation like me and he/ she wants that high, shooting crack is the only option. If I had to choose, there's no question of which one I would choose. When I used to live in NYC and London, I had access to very high quality cocaine. Those days, I used to always get powder because IV was the only route which I consumed. But now if I want to shoot, crack is usually the only option.
