The good people at NORML have a story on the falling numbers of teens who use Marijuana in states with medical Marijuana laws. I can't explain it, it seems it would be easier to get, since the medical clubs make it so easy for patients to access their medicine. Here's a snip:

Among the twelve states that have legalized the use and cultivation of medical cannabis, all but one (New Mexico) have experienced an overall decline in teen marijuana use since the enactment of their medi-pot laws. (Data was unavailable for New Mexico, which passed its law last year.) In seven of the twelve states, marijuana use among young people declined at rates that exceeded the national average.

Good news for medical Marijuana advocates.
