Yeah pretty much anything can fuck up your body if you do too much of it for too long in the wrong ways.
Weed can be behaviorally addictive even though it doesn't cause the same kind of neurochemical dependence. Caffeine is just literally an addictive stimulant and nobody talks about how insane it is that it and nicotine are just legal for some reason when a bunch of other stimulants that also cause heart problems aren't. Let your kid play the wrong video games and suddenly you have a 10y/o with a gambling addiction. Even running is great cardio but it can literally fuck up your skeleton if you run on the wrong surfaces and wear the wrong kind of footwear.
You gotta pay attention to all the shit you're doing pretty much all of the time to catch whatever your 'thing' is gonna be before it damages your body permanently. It's exhausting. That's the main thing rich people have over poor people health wise. They get enough time off from both work and domestic responsibility to watch that kinda stuff and intervene with a different coping strategy when it's getting out of hand. Sure not all of them take advantage of that but that's a personal problem at least they have the time to do it if they want to.
Edit: it's wild to think someone thinks something I'm not even gonna bother arguing about is worth that much trouble.
