>t has no effect on participant's attitudes toward (or propensity for) drug use
Which is really crazy, if you think about it. Multiple years of training and indoctrination have no effect. In some ways, that gives me hope for America.
The cynical view is that DARE is pro-law-enforcement training and indoctrination, where the anti-drug focus is simply window-dressing to sell the program to parents and the public.
Even if it doesn't trick kids into thinking police are cool (which, honestly, I don't believe it does), running a DARE course is easier than most other police work, and pulls in federal subsidies too. So it benefits police even if it doesn't convince anyone of anything.
