Hmm... I was thinking recreational use, not medical, but I didn't specify.

So original questions reposed with that caveat.

Other than being in hospital, or when traveling across international borders, I've smoked pot pretty much daily since March 11, 1977. About a year later tobacco started making me ill. Quit smoking tobacco August '78, after a summer of trying to find a brand of cigarettes that didn't make me barf.
