Crack is an ugly drug to get involved with. Your clients have little to no money, they smoke up any money they have immediately, and when they go into withdrawal they are willing to do do pretty much anything with no moral boundaries.
Of all the addictions on the street, people look down the most on those addicted to crack. Likewise, those who deal in it aren't respected, because they simply hang around the absolute wrong kind of people. Uncontrollable, untrustworthy, predatory people. Yet a crack dealer has to manage them somehow. They have to be tougher than a crack addict - and let me tell you that is some tough.
