“A Walmart employee with sinus cancer and an inoperable brain tumor who was fired for using medical marijuana will not be rehired, even though the company says it is ’sympathetic’ to his condition. Joseph Casias, 29, was fired in November from a Walmart store in Battle Creek, Mich., after marijuana was detected in a routine drug screening that he underwent after he sprained his knee at work. Casias, who was the store’s 2008 associate of the year, said he legally used marijuana to reduce pain associated with his disease and was never under the influence while at work.” (03/17/10)
