I dunno. When tobacco users are paying more in taxes then the wholesale of the product sale then I'd say something is really punitively wrong. Most of those taxes don't go to tobacco cessation program. They are just slushy tax dollars legislators gouge a particular customer over. I also totally agree with your reasoning that their dream tax rate on marijuana is going to ensure the black market is profitable enough to keep right on going without missing a beat, possibly just a few less growers. That said, there's going to be quite a few smokers that will be pleased they no longer risk getting their supply from a shady part of town.
