As other comments have noted, just like with other addictions, it is extremely helpful/insightful to be able to see someone "further along" and say "I don't like what I see." I interacted with and heard stories about family alcoholics when I was growing up and that is part of why I'm confident I won't develop a bad relationship with it myself. It's hard to forget what it does not just to the users, but to everyone around them. Similarily, although I didn't see it growing up, as an adult I have seen some pretty hardcore stoners (high all the time), and I do not like the lifestyle that most seem to fall into. It's really easy to notice the cognitive decline when it happens to someone you know. Even if you want to be charitable, people at the very least behave quite differntly when they go from generally sober all the time to generaly stoned all the time. YMMV but I prefer generally sober people versus generally stoned people. I think part of the strong correlation between stoners and legalization movements is because they're (rightfully!) self-interested in improving their own lifestyle, so they'll be the loudest and most experienced advocates. As much as I loathe the "marijuana can do no harm" attitude of some stoners, the still reactionary "omg drugs bad!" people are terrible. Making it illegal makes it so much worse for everyone involved, and you're not going to stop people from being involved with marijuana. More or less the same reasons we need to legalize sex work. It's here, it's always been here, and we need to learn how to cope with this reality in a healthy and safe manner. "Abstinence only" doesn't stop babies from being made any better than it stops people from using drugs. Education is the key (as it so often is).
