A former Foster official is suing the town in federal court over medical marijuana. Former town public works director Robert Hohler says he was forced to take a drug test, and was fired in 2013 when he failed the test. Hohler says he has a medical marijuana card to ease pain from a car crash that left him with liver damage and caused him to lose a kidney and his spleen. He's also accusing town officials of disclosing private medical information that has damaged his personal and professional reputation.
