I agree and I've seen the same.
However as far as actual physical health (rather then mental or social) I believe cannabis to be far less detrimental.
It might demotivate a person but it doesn't flat out kill them.
Is it also possible that alcohol is the lubricant for a society with dysfunctional social and environmental principles? Perhaps what we sometimes describe as motivation or personal growth isn’t actually that valuable when directed at goals that destroy the planet and isolate us from other humans.
I've seen more lives around me hampered by marijuana than by alcohol, despite having a very large amount of heavy drinkers in my circles.
