Boston has become the largest city in the US to offer prescription drugs from Canada. It's a move that Mayor Thomas Menino thinks will save the city about one million dollars in its first year. Menino is backing the pilot program in spite of the Food and Drug Administration's expressed concern about the safety of imported drugs. The mayor says the Canadian pharmacy providing the meds ensures quality and requires safeguards. The Boston program covers about 14-thousand city workers, retirees and dependents. They'll be able to choose discount drugs from a list of about 50 developed by doctors and pharmacists. Several states and cities have turned to Canada for drugs. Despite a federal ban, none has been prosecuted.
