Well, first of all, most people don't smoke marijuana by the ounce lol. An eighth of pot is currently around $60 on the black market, and legal sellers would probably keep the price around the same to compete. Which means, even with a $50 an ounce tax, assuming prices stay the same, there are huge profits for sellers. At the same time, pot is much cheaper than cigarettes for the user, since an ounce would probably last a casual smoker weeks or months.
