Kid's Pot Use Declines in Colorado

I'm not one to take polls or studies at face value but U.S. New and World Report reports that juvenile use of marijuana in Colorado seems to have declined after it was legalized. There's some mention of it possibly being the result of a long term trend that started before legalization.

I've been led to believe that drug use goes up and down among all groups regardless (or in spite of) changes in legal status. Then again, my best friend for a while when I lived in Tustin, CA told me he wouldn't smoke pot if it was legal. As far as I could tell he was totally serious. Anyone else know anybody like that?

I haven't smoked pot since the early '80s. I quit mostly because I didn't like the crowd that came with it, at least at the time. It also tended to aggravate my social anxieties (I've heard the same thing from some others). I suppose given the right place and time I might smoke it again but have no great desire to- legal or not.
