You are, of course, correct. And most of the medicinal applications do not involve smoking it or a high.
It really does help and I'm convinced that there are all kinds of benefits of marijuana that have nothing to do with getting high. I do believe in medical marijuana for those with cancer and other conditions that it really does help alleviate the symptoms and get those patients to eat when they otherwise may not.
I don't subscribe to recreational marijuana although it's getting more and more difficult to see "why not?" and tax it the same way alcohol is taxed and put the same restrictions on it. Anyone who wants to get high is going to do it anyway and I don't believe that people like me who don't do it and won't do it even if it's legal aren't going to magically going to start getting stoned every day.
At this point really, what is the difference between marijuana and alcohol? I'll tell you: the police can do a breathalizer to see if you're driving drunk. Figuring out whether or not someone is high on pot is a whole different problem for which there isn't as simple as a diagnosis. That and people these day vape pot so they don't smell like they've been smoking it....
