I think people are getting overly hung up on the specific terms. Addiction. Dependency. That syndrome thing mentioned before. They are all similar enough.
The psychological vs physical part is in my opinion more important.
Again in my opinion with weed the psychological part dominates.
Unlike harder physically addictive substances like nicotine, alcohol, speed, heroin etc.
From a personal anecdotal POV I consider myself an addictive personality. But I only get "addicted" to some things thankfully.
Some addictions are deadly, some are not great but relatively mild, and some are arguably downright wonderful.
My most dominant lifetime addiction is to coffee. It is definitely a physical addiction and there are definite very unpleasant long term withdrawal symptoms.
I see no good reason to quit.
I was a very habitual daily weed user (bong) in my adolescence for about 4 ir 5 years. But I still got good grades. I think it was psychological addiction. One day I decided it wasn't fun any more as it made me paranoid and I quit cold turkey.
Physical withdrawal was hardly noticeable. Nothing compared to the times I foolishly quit coffee.
Taking up the new weed world decades later with the fancy strains and dry herb vaping I haven't felt paranoid at all. I also see no point in getting high every day.
A person's reaction to weed and other substances are highly individual.
