A medical marijuana vending machine generating plenty of buzz in the media has made its debut in Denver, one of the largest MMJ markets in the country.

Doctor’s Orders – a dispensary just north of the downtown core – recently began offering patients the ability to purchase cannabis-infused cookies and candies via the machine, which is called Zazzz.

American Green, the company behind Zazzz, unveiled the machine earlier this year to much fanfare. Executives announced in a press release earlier this summer that their “initial common goal” with investors was to place 1,500 vending machines.
