> Daily or near daily use of nearly 50% of users sounds like it must be habit forming..

Practically all of those daily/near daily cannabis users (5/6th of them) are tobacco smokers, as I also pointed out.

From the third article I cited: https://www.publichealth.columbia.edu/news/cigarette-smokers... says, compared to non-smokers, smokers are 5 times more likely to be daily cannabis users.

Tobacco is intensely addictive.
