The only reason they are running out of weed is the sweet heart deals they made with the liquor distributors in the state. You cannot ship marijuana from farm to dispensary without involving a liquor distributor to transport it for you. That costs a bunch as you can imagine a monopolized distribution system would. Of course, the only reason they made that deal was to quell any opposition from the liquor distributors in NV. So its not so much that the weed is flying of the shelves, although I am sure it is, its that they don't have the throughput to transport product from source to sale.
