They are not out of line with the claims in the study. I would particularly emphasize the issue of dependency. Almost every pot smoker I have ever known had to smoke multiple times a day.
There was a 29 or 30 some yr. old guy living in our area who was said that he was always high. It was said to me that if it weren’t for pot he’d probably be one bad dude without it....
So apparently it mellows some folks who would ordinarily be violent.
Even so ...I’m not for it’s legalization and believe it’s a terrible mistake that it is now.
