Portland Dispensary SERRA has a downtown location bringing you quality drugs and other fine cannabis accessories. We are both OLCC recreational and Oregon Medical Marijuana Program (OMMP) compliant; medical patients shop tax-free. We can be found in gorgeous downtown Portland, just a quick jaunt from the SW Oak/1st Ave Max station (stop ID 8380). We are cash-only, accept CanPay payments, and have an ATM available for all customers. Recreational customers must be 21 or older to enter. OMMP patients 18 and older are also welcome.
