I wouldn’t call it addiction, in most cases it is dependence…unless your facing legal trouble due to your use, but keep smoking. But that’s more to do with shitty legal practices.
I’ve been addicted to real addictive substances and weed ain’t the same at all ime.
For long time users, stopping can cause some withdrawal symptoms, sure, but nothing worth fear mongering over imo.
It really varies person to person. Some people let it run their life. Others not so much.
