Illegal Drug Use Among Teenagers Continues to Fall

Washington Post
I don't understand why there is any difference between abuse of illegal drugs like cocaine and heroin and prescription drugs like OxyContin and Vicodin.

If the Office of National Drug Control Policy truly believes the usual source of those drugs is a parent's medicine cabinet, then we may as well have no such office. Most of those drugs get into users' hands by way of robberies, burglaries, and organized forgery -- all of which are just as serious crimes as any of the smuggling and so forth that brings illegal drugs across our borders from overseas.

Perhaps the fact that the prescription drugs aren't produced by subsistence farmers in faraway countries, and have their own rather well-funded lobby in Washington, has something to do with it?
