Ethics authorities in New York and Georgia recently issued opinions on whether lawyers can advise clients on matters related to both recreational and medical marijuana that reach opposite views. The problem relates to the fact that marijuana use is now legal in many states while it remains illegal under federal law.
The New York opinion, issued on July 8, 2021, states that attorneys are free to provide advice for clients in the medical cannabis industry, while the Supreme Court of Georgia took the exact opposite position in an order issued on June 21, 2021.
