One of the best medical shops I have ever found. The staff is so incredibly helpful and knows their way around all of their products. Additionally, as a small business their product is always extremely reliable and affordable. If you’re looking for a reliable dispensary in the Palisades area this is the place for you.

Absolutely love the atmosphere here! I always feel so warm and welcome whenever I go here and the staff is amazing too. They help find the perfect strains that are just right for you! And lastly the products here definitely put others to shame and I can always trust that quality of the products are great and safe🌸

I absolutely adore this place. My first time at a dispensary in DC and they provided hands down the best service I think I've ever had!! Everyone was incredibly friendly and they took the time to actually ask me questions to find the perfect product FOR ME. Highly recommend if you are looking for a spot with a big inventory selection and amazing customer service.

Amazing experience! Walked through the door with a friendly welcome and smile. Green theory and the people who have poured their souls into this medical dispensary business assisted me very thoroughly with my wants and needs. Best customer service and they made me feel safe. Their products & services are top notch. I’m a sativa & hybrid girl myself, but will come back here to try their other products. I 100% recommend coming here for any wants or needs you may have.

Washington D.C. legalized recreational cannabis possession and home growing in 2014 through Initiative 71. However, due to a Congressional spending rider, commercial sales remain technically blocked. A gray market of "gifting" services has emerged. Medical marijuana has been available since 2010.

Medical: 18+
Rec: 2 oz (56g) possession limit. No legal retail sales (gifting only).
Med: 4 oz per month from licensed dispensaries
Prohibited. Cannot consume on any public space, federal property, or in any vehicle. Given D.C.'s unique federal status, this is especially strictly enforced near federal buildings.
Adults 21+ may grow up to 6 plants per person (no more than 3 mature) and up to 12 plants per household.
Allowed
Medical cannabis is subject to 6% sales tax. No recreational tax exists because there are no legal recreational sales.
