Anecdotally speaking, this has been my experience as well. I would even go so far as to say the kids I know who smoked the most (or had that reputation) are the ones with the most/worst psychiatric issues as adults.

I have nothing against cannabis use and I do not judge people who use it, but I think parents who are too accepting / forgiving of their teenagers’ use are doing them a disservice. Additionally, when I was a teen, kids were smoking actual, real weed. These days, kids are vaping and using what are essentially poorly tested/understood pharmaceuticals. I won’t claim to be an expert in the topic, but I certainly think there’s ample reason to be concerned about the effects of these things.
