No I never have, I have nothing against those that do occasionaly and don't cause anybody any harm. I just have enough problems staying in touch with the world as it is with all of the movies and books I use as distractions, it is why I don't drink or smoke either. Control over myself is in such short supply anyway, that I do not need to test it.
Q: What Native American tribe/culture/period do you find the most interesting?
