Walmart fires Michigan man for using medical marijuana

Now that medical marijuana is legal in Michigan, can an employer fire a worker who tests positive for the drug? WalMart says it can, so it did. "I was terminated because I failed a drug screening," says former WalMart employee Joseph Casias. In 2008, Casias was the Associate Of The Year at the WalMart store in Battle Creek, despite suffering from sinus cancer and an inoperable brain tumor. At his doctor's recommendation, Casias says he legally uses medical marijuana to ease his pain. Casias showed WalMart managers his state medical marijuana card, but he was fired anyway. "I was told they do not accept or honor my medical marijuana card," says Casias.
