I lived in a state where pot was legal. (From 1973-1997). It was a disaster. Most of the women I went to high school with ended up as addicts and on public assistance.
Back in the 1980s, it was normal for people to smoke pot, then pick up “causes” so they could get together to party. As an example, I was invited once (turned it down politely) to go to an “environmental” “festival” in Eugene. The real goal of those going to it was to get stoned and to “get laid.” That has been typical of “causes” unfortunately— an excuse to get loaded and to “get laid.”
