I think we should be doing a ton of research on the health implications of marijuana use. However, I don't think that should affect legality other than, perhaps, regulations on distribution. Legalization didn't happen on the back of "no long term health problems" it happened because throwing people in jail for a relatively non-addictive substance is unjust and eventually people had enough of it. But the question does seem a bit silly. Like, yeah it's probably not totally salubrious to get blazed every day. No need to clutch pearls. It's also not healthy to get drunk every day or eat tubs of ice cream constantly but we feel as a society that the freedom to do those things is worth some of us overindulging and hurting ourselves.
