What’s the effect in the aggregate on the average person? It seems to me that many (most?) don’t have the willpower to really make smart choices with it, and default to watching cartoons and eating snacks.

We’re watching this happen to a friend of my BIL now and it’s hard to watch. To be fair the kid’s problems started with his parents exercising “choice” to pursue serial marriages instead of raising their kid, but smoking pot (with a blow torch apparently?) isn’t helping.
