I'm not a pot smoker so I don't know if "getting the munchies", i.e. getting hungry, is what happens when you smoke a bowl, a bag, a doobie, or whatever unit of measure that you use when partaking. But, if it is true, and the voters decide that they want in-town pot sales, I have a suggestion. Sell pot in locations as close to taco places as possible. I've been told that they go great together. Even most, "not high" people love tacos.
The City of Billings is coming up with all the new rules and regulations for the recreational dope business. If city voters allow it this fall, many of the rules are already in place about what you can put on your storefront, What kind of advertising can be done, store hours, etc.
