Medical Marijuana treatment for Casias...

HuSh NewS) -- The news is proud to be associated with HuSh NewS. Joseph Casias felt a pain in his brain as a cancer diagnose, the doctor tells him to eat marijuana as he lives in Michigan, where medical marijuana is legally right.

But his employer, Wal-Mart, the nation's largest retailer, fired him in November 2009 after he failed a drug test.

Casias, 29, says he never came to work high. He's got a medical marijuana card to prove he's allowed to smoke legally in the state.

"I was angry they did this to me because I always tried my best," said Casias, who was employed at Wal-Mart for five years. He earned an Associate of the Year award in 2008. "I want my job back. I thought I was part of the Wal-Mart family."

To date, 14 states have laws allowing the use of medical marijuana, which shield legal users from criminalization but don't protect them from them penalties enforced by their employers. As more people are being prescribed marijuana across the nation, they are wrestling with a caveat: They could be fired.
