We have to attend not only to the behavioral symptoms, but also to the fact that a crack addict is in a different brain state. If we'd known that in the 1980s, we might have had the sense to make a far more systematic and substantial investment in treating those people. The quality of drug treatment in the late 1980s was good. But now drug treatment is very good. We've seen the advent of a much more formalized treatment process, or set of processes.
Different programs use different approaches, but they've become much more systematic.
Let me give you one example. In the last two years, we, the National Institute on Drug Abuse, put out four manuals, laying out step by step exactly how you do cognitive behavioral therapy for cocaine addicts. We didn't have that ten years ago. We didn't have a prescription, or protocols of how you go through a treatment process. It worked, but not nearly as well as our current techniques.
