Yea you're right. I guess with the recent "drug war," prices on wholesale crack have probably gone up.
Also, due to this prices on street crack have gone up, and so people are more likely to resort to violence to get it.
I guess you could always get a runner, to get the money, then bring out the crack. But then, even though you have more safety, the runner gets some of your money.
