Connecticut’s legalization of medical marijuana has caused ethical concerns among lawyers who are interested in the business opportunities they might gain from potential growers and sellers, but reticent about providing professional services tied to the sale of a substance that is still considers illegal under federal law.

But now the state Judicial Branch has removed some of that uncertainty. On June 13, the Judges of the Superior Court amended the state’s Practice Book Rules to ensure lawyers they won’t be faced with ethics complaints or even disbarment if they represented licensed marijuana distributors, none of whom have actually started doing business yet.
