Residents and employees of Missouri’s seven nursing homes for veterans will not be allowed to use medical marijuana. Missouri Veterans Commission Executive Director Grace Link said Monday the state must prohibit the use of medical marijuana at the homes in order to comply with the U.S. Department of Veterans Affairs, which considers pot an illegal drug. The decision affects around 1,300 residents of homes. Federal funds pay part of the more than $80 million needed to operate the homes and Missouri officials don’t want to jeopardize that revenue.
