Medical marijuana advocates are applauding a new memorandum issued Friday by the U.S. Departments of Treasury (DOT) and Justice (DOJ) giving long-awaited guidance to financial institutions, such as banks and credit unions, to provide services to marijuana-related businesses in states where it's legal. A refusal to engage in these services has plagued medical marijuana businesses for years, dating back to the Bush Administration. Due to an aggressive accelerated policy under Obama Administration, States like California, Colorado, Washington, Michigan and others have been forced to deal in large amounts of cash.
