Duane Morris has been representing cannabis clients for a few years, and now the firm is casting its lot even more closely with the fledgling industry.

The Philadelphia-based Am Law 100 firm is partnering with the American Trade Association of Cannabis and Hemp. ATACH promotes the expansion of legal marijuana sales for industrial, medical and adult recreational use, and its members include businesses in the marijuana and hemp industry, as well as established companies looking to enter it. According to both sides, it’s the first time a national cannabis trade organization has teamed up with an Am Law 100 law firm.
