It's a losing game to try anything more. One argument against simply waving the white flag is conceptual, and another rests on practical grounds. The conceptual complaint is that tolerating an evil is itself evil. Heroin, cocaine, and above all crack-cocaine are, by this logic, something entirely different. They take over the user's mind and body so completely that it is hard for him or her to do anything but sustain the addiction.
Human beings have a purpose beyond merely nodding off in a drug-induced haze.
So say the moralists, and in isolation their case is irrefutable. But their view has the same drawback as does the conceit that whenever there is evil in the world, the United States should immediately dispatch troops to correct and end it. The hard truth is that some evils must be tolerated because there is no practical way to correct them. All the evidence of our failed anti-drug war suggests that no matter how earnest we are about extirpating this evil, we will fail. Some opponents of the white-flag view take the opposite tack.
