D.C. Mayor Muriel Bowser has signed emergency legislation extending conditional medical marijuana licenses and strengthening enforcement authority against businesses selling marijuana or other controlled substances without authorization. The Medical Cannabis Licensing and Unlicensed Establishment Enforcement Clarification Emergency Amendment Act of 2026 is scheduled to expire Oct. 28. The law also allows conditional license applicants to submit a zoning certificate instead of a certificate of occupancy when seeking a permanent license. Medical marijuana retailers and internet retailers generally cannot operate within 400 feet of a preschool, primary or secondary school or recreation center. Similar enforcement authority applies to licensed medical marijuana establishments engaged in certain unlawful activities.
