Bad news cancer fighters, arthritic sufferers, and those of you who worked so hard at getting your medical marijuana ID card under false pretenses: employees who partake in the kind medical bud at home can be fired for testing positive for the drug at work. Which? Wow.

In a 5 to 2 decision today, the court claims that Proposition 215, "the 1996 state initiative that allowed Californians to use marijuana for medical purposes with a doctor's recommendation," no longer protects workers from getting fired for violating federal drug laws before, during, or after work hours.

What's more, an employer who knowingly hire a medical marijuana user is "'arguably being complicit in an activity that's illegal under federal law.'" This chink in the cannabis armor comes on the heels of the U.S. Supreme Court's continuing approval of the federal government's strong-arming local medical mary jane offices and suppliers for "violating federal laws that ban the possession, cultivation and distribution of marijuana and recognize no legitimate use for the drug." (An aside: Aleve does wonders for pain, folks, especially when mixed with two Benadryl. Just saying.)
