They won’t die but they have trouble functioning. And they are vastly entertaining to their classmates.
That's what I thought.
I recall the addiction debates on this from the past.
Alcohol as a depressant is physically addictive so much that under extreme conditions abrupt withdraw can cause death,
Pot is not physically addictive but as a mild hallucinogenic it is psychologically addicting to many and leads them to desire stronger drugs for a stronger high, which can be serious. Others seem to have no problem with moderate use.
I recall potheads in HS (Long ago for sure) wanting nothing but to get high every day.
I am on the fence on this one.
