This place is awesome. I have been to multiple locations throughout Boulder and I can't help but go to MMJ. I have a high tolerance and college budget so I only go to places that I get the most bang for my buck. I always go to MMJ not only for its great bud, but for its friendliness. The security attendant Tyler is always outgoing and respectful towards every customer. Great guy to hang and talk to while the bud attendants are helping others. The bud attendant I see once a week is Mark. He is an awesome dude. He is very knowledgeable about the trade and always recommends potent strains for great prices. I have never had a bad trip to MMJ, the weed is worth its weight for the price and the customer service is outstanding. I highly recommend going to see Mark and Tyler at MMJ.
