The rapid expansion of legal medical and recreational cannabis in numerous states across the U.S. has opened up significant opportunities for new business ventures and investments. The demand for medicinal and well-being cannabis products is also growing quickly in the U.K. However, this highly regulated industry is subject to stringent licensing and compliance requirements both in the U.S. and U.K., impacting such diverse areas as employment, agribusiness, capital markets, financial services and banking, land use, health care and intellectual property law.

Armstrong Teasdale’s Cannabis and Hemp Law practice area has significant experience advising and assisting companies in securing and keeping licenses to cultivate cannabis, manufacture cannabis-infused products, and dispense flower and infused products. The majority of Americans live in states with laws authorizing the cultivation and sale of medical cannabis, and a number of other states have commercial recreational cannabis industries. Almost all the remaining states authorize the production of hemp for commercial, research or medical purposes, including the manufacture of cannabidiol (CBD) to treat certain medical conditions such as epilepsy. Opportunities in the hemp space have multiplied with the passage of the 2018 federal Farm Bill, which excludes hemp from the Controlled Substances Act’s definition of cannabis. The United States Department of Agriculture has published rules governing state and federal licenses to lawfully grow hemp.

Along with the potential for new jobs and revenue, these expanding industries present numerous federal and state compliance burdens, which are often implemented through multiple regulatory agencies. In addition to direct regulatory oversight from licensing authorities, Armstrong Teasdale attorneys help clients comply with other regulators in this space, such as the Food and Drug Administration and the Federal Trade Commission.
