I discovered Paresthesia, as a pleasant consequence of smoking pot, a long time ago.

Bill Weaver once asked me, rather hostilely, what the elaborate swooping gestures that I made sometimes around my body when I was stoned meant--and I didn't get a chance to say so then, but I started to say, "pleasant tingles." Of which the Dark Side, it seems, is Diabetic Neuropathy. And which is all being talked about these days under the rubric of 'videos which give you a frisson.' Ha, the Modern Age.
