I'm about the same age as you but when I was a teen, the "freaks" or "heads" as we called them were actually not troublemakers or law breakers. They just wanted to get high and go to concerts. As an adult, if I had to choose, I'd hang out with potheads over drunks. I've never seen anyone get high and want to fight everybody....
Stoners drive slow and cautious with good motor skills.
Drunks drive fast, crazy and motor skills are gone out the window.
My "opinion" is that those teens who currently illegally use recreational pot are more prone to break other laws. "Bad boy syndrome". Making it legal I doubt would have any material impact one way or the other on their propensity to commit other crimes.
