WAL MART FIRES EMPLOYEE ON PRESCRIBED MARIJUANA

ABC NEWS - Even though Michigan resident Joseph Casias had a prescription from his doctor for medical marijuana, he was fired after a positive test for the substance by his employer, Walmart.

The news last November he'd been terminated was devastating for Casias, 29, who took great pride in his job, once earning the honor of Associate of the Year.

"It hurts. It hurts because I care. I care a lot about the store. I always wanted to make sure I do well," he told ABC News.

Casias started taking the medicine last June to cope with pain from sinus cancer and a brain tumor. He says the rare form of cancer causes him pain constantly and he almost died when he was first diagnosed.
