A Michigan man who was fired from Wal-Mart when he failed a drug test due to his use of medicinal marijuana has filed a lawsuit against his former employer. Joseph Casias claims in his lawsuit that in November 2009 he twisted his knee while at work.
Under Wal-Mart policy, employees who are injured at work must take a drug test. The lawsuit claims that Casias showed his bosses the paperwork from the state allowing him to use medicinal marijuana to alleviate pain from a brain tumor, but he was fired regardless after failing the drug test. The lawsuit seeks unspecified damages.
