Back when I was using weed on a regular basis, I was still years away from being officially diagnosed, and nobody was talking about "medical marijuana' in those days. However, I would still say it was medicinal for me, because, after being a silent wallflower my entire life, suddenly I had actual friends, that I hung out with on a regular basis, and actually interacted with, by talking about our mutual interests, most of which involved music trivia and record collecting.
Those days are long gone, as are my days of dating, and other social activity, and now I'm back to living in my own tiny space, chronically alone and trapped inside my own head. So I'd say in my case, "medical" marijuana was the only thing that ever gave me anything resembling a normal life. I miss it.
