Been coming here a long time, have recently gotten to know the staff better. Prices are decent and they usually have some pretty good sales going too. They also really love dogs so if your pupper is well behaved and people friendly you can bring them in to get a treat and get loved on while you get your stuff.

I’ve been coming to Green Dragon for the past 3 years! Very convenient living only a mile down the road. Leslie was the Bud Tender that helped me out with an awesome recommendation on some “Down Shift” from green dot labs, she’s always very welcoming and knowledgeable on anything you might need help with especially the Deals they have going on!
