Duane Morris (Cannabis Practice)

Duane Morris's cannabis practice serves businesses and individuals across the supply chain — cultivators, processors, distributors, dispensaries, investors, and vendors — as well as non-cannabis companies entering the space (private equity, banks, real estate developers). The group covers state licensing and regulatory compliance, corporate formation and M&A, litigation (including RICO, contract, trademark/patent, and employment disputes), federal and state tax planning (including IRC Section 280E), real estate/zoning, intellectual property, securities financings, and bankruptcy. The practice has been recognized by Law360's Cannabis Group of the Year, Chambers USA, and The Legal 500.

Duane Morris LLP was founded in 1904 and is headquartered in Philadelphia, Pennsylvania, with roughly 750 attorneys across some 29 offices in the U.S., UK, and Asia as of 2026. Cannabis is one specialty practice inside this large, diversified full-service firm rather than a standalone boutique.
