I think it'd be fine treated as a controlled substance, since I seriously doubt is ever going to be legalized everywhere. It has a ton of medicinal benefits, but when it comes to treating things like depression and anxiety, but it's just a tool, same as any pill, and ultimately still needs to be accompanied with some form of counseling or therapy to be really beneficial. For example, it's not really effective to prescribe someone suffering with depression pot, then send them home to smoke it and sort things out on their own.. And like with a ton of prescription drugs, it can effect different people in different ways. How much you smoke or consume and the actual type of marijuana itself can be the difference between making someone with anxiety really mellow or a lot more anxious. Again, like with prescription drugs, it's not really a one size fits all deal. In regards to long term pain management, something a ton of people struggle with, I think it's an amazing option for people who would otherwise have to rely on opiates, which are pretty rough on the body over time and can create dependency and a string of other problems.
I've used it recreationally on and off for the past 10 years, and I don't use it nearly anywhere as much as I used to these days. For me it's no more severe then having a couple of drinks, only I become much less talkative, and it honestly gives me the best, most sound sleep I've ever had. I'd like to distributed in a controlled setting here. I've been ripped off by getting less then I've payed for more times then I can count, and been robbed at gun point with friends once. So go and buy it from a store without fuss would be nice, and would undoubtedly cut down on crime.
But I mean, yeah, just like with anything else, use it responsibly. If you use it recreationally there's a time and a place. If you know it makes you droopy, maybe don't get stoned out of your mind before going to work, same as you wouldn't clock in piss ass drunk. If someone doesn't like the smell, don't smoke around them, same as you wouldn't with cigarettes. I don't really think it's safe to drive high, I can't and don't, and I've had friends get into fender benders in the past because they zone out. I've known people who all they do is smoke all day and all they talk about is smoking all day, and it's really obnoxious and annoying.. All things in moderation.
