Welcome to Greenwerkz!  Founded in 2009, Greenwerkz is a Colorado-based medical cannabis company.  We provide our customers with high-quality, organically-grown cannabis, along with many other non-smokable cannabis-based products.  Our three Colorado locations can be found in Denver, Edgewater, and Glenwood Springs.

Greenwerkz practices a Free Range Organic, soil-based grow method.  This includes no force feeding of minerals, no pesticides, and no chloride or fluoride.  We tend to and water all of our plants by hand, and our grow teams’ attention to detail is clear in the quality of cannabis you see on our shelves.  For a list of current strains, click here.
