Buying legal cannabis in Washington, D.C., in 2026 is unique because while recreational use and possession are legal, recreational are technically prohibited due to federal restrictions. To purchase legally, you generally must use the city's Medical Cannabis Program , which has been streamlined to be highly accessible for both residents and visitors through a "self-certification" process. 1. How to Buy: The Self-Certification Process
In 2026, the only fully regulated way to buy cannabis is through licensed medical dispensaries. You do need a doctor's recommendation; you can certify yourself as a patient in minutes.
If you have a valid medical card from another recognized state, you can shop immediately.
If you don't have a card, you can apply for a temporary DC visitor registration (e.g., $10 for 3 days or $100 for a year) and shop immediately upon approval.
Most people complete the Online Application in about two minutes. You will receive a digital registration to use right away. 2. What to Bring and Expect D.C. Dispensaries | How to Buy Weed Legally in D.C.
