For clarification I wasn't referring to the funeral industry as a "Sin Tax" -- I just included it because it was a quoted industry so we can agree to discard it. My point is "Sin Taxes" in the case of tobacco are extremely stable even if predictably dwindling. Tobacco is universally and legally available. Marijuana isn't as addictive but luxury goods/Sin Taxes have a whole different set of economic laws applying to them that makes them stable and both MJ and tobacco are luxury goods.
