Devon Medical Marijuana Dispensary

Keystone's Devon medical marijuana dispensary opened in February of 2018 and offers a wide variety of medical marijuana products, including vapes, extracts, flower, tinctures, capsules, lotions, RSO and other medical marijuana products. Our dispensary is located off Lancaster Ave, across the street from Fred Beans Volkswagen of Devon about 15 miles outside of Philadelphia. The area of Devon is known for its oldest and famous horse competitions, the Jenkins Arboretum, and plenty of art, parks and cafes easily accessible by a short drive.
