“The Obama administration issued new rules Friday intended to ease the concerns of banks wanting to deal with businesses that legally sell marijuana. While 20 states and the District of Columbia have passed laws allowing the sale of medical and recreational marijuana, its production, sale, and possession remain illegal under federal law. And because the federal government regulates banking transactions, marijuana dealers have been unable to get banks to do business with them. As a result, dealers operate strictly with cash, creating a tempting target for thieves. Treasury officials say the revised rules should reduce the dangers associated with conducting an all-cash business.”
