I had a masters in smoking the stuff and observing it worldwide quite a bit until a couple of decades ago.
I’d rather my kids abstain from dope but I would place occasional pot smoking...note I stress occasional....as the least dangerous drug...it is less dramatically abused than alcohol.
So you’re saying the medical researchers in the study were lying? On what basis?
A joint DOESN’T hit the lungs like 5 cigarettes? It DOESN’T cause the lung damage that showed up on the CAT scans? Did they falsify the results to prove the point they wanted?
