I've been using marijuana a lot in recent times as a way to help relieve depression, and in my experience it has done nothing but turn my life around. Of course, marijuana is very subjective, just like every other type of medicine. Everyone reacts differently to marijuana, some suffer no ill effects and have heightened moods while others have extreme anxiety or paranoia/headaches as a result. I'm not going to take adderall unless I have a medical need, in the same way I wouldn't take marijuana if I didn't have a medical need. Of course, the medicinal use comes packaged with a high so it becomes a controversial topic. Any medicine requires good dosage, and of course a high dosage of weed means you're incapacitated on a couch.
So yeah I think weed is fine, just like cigarettes and alcohol of course there should be designated places for smoking outside of rang of the public, its natural that not everyone is keen on the smell. And, if it's regulated by the government, there's no worry of shady dealers lacing their product with pesticides and stuff. Plus, tax the industry and make a forgetton of money. Colorado is rolling in it rn
Edit: Also, I went through stages of therapy and many conventional depression medications which did nothing to help my case for several years.
