I've seen a lot of these talking points before by the pro-drug crowd. "It taught kids about interesting drugs that they probably wouldn't have learned about otherwise" is laughable when subjected to scrutiny. You'd have to live under a rock to otherwise not learn about the drugs the DARE program teaches (and they don't get particularly exotic either). The idea is asinine to begin with - you'd want kids to know about exotic drugs and their side effects to know to avoid them in the first place.
The worst part is that the pro-drug crowd, like yourself, touts these talking points in an attempt to end the program - to what end? If I accept your talking points blindly that the program has failed, does that mean we simply stop trying? It seems less that you disagreed with the implementation of the program and more that you don't believe kids, or anyone, should be dissuaded from drugs.
