I agree. Why not bring out the Volcano if you are around friends who would vaporize with you? ANother idea, is to have a cheap e-cig Cannabis pen, just for other people. I hate sharing things like that, too, but I'd keep an extra Volcano balloon, or a spare cartridge for my vape pen, if I was going to be around friends who I wouldn't mind sharing with. I know people use Cannabis for medical purposes, and some people ONLY use it for medical purposes, but that doesn't take away from the fact that it is very commonly used as a recreational drug. It's not exactly the same, but if someone has a glass of wine at night to ease anxiety, their company would still see it as a glass of wine, and not a dose of medicine. Perhaps, if you made Cannabis gel caps, and used those when you were around people, they wouldn't even know what it was. You could just pop one in the bathroom or something. With that in mind, you could also take a few vape pen rips in the bathroom as well, without anyone being aware of it.
