(AP) — Pot may be legal in Colorado, but you can still be fired for using it. Now Colorado’s Supreme Court has agreed to review a marijuana-related firing in a case that could have big implications for the state’s pot smokers.

The court agreed Monday to review the case of Brandon Coats, a quadriplegic medical-marijuana patient who was fired from his job at Dish Network in 2010 after failing a drug test. The company didn’t allege Coats was ever impaired on the job.

Dish Network argued medical marijuana use isn’t a “lawful activity” covered by a law intended to protect cigarette smokers from being fired for legal behavior off the clock. A Colorado appeals court agreed last year.

A Supreme Court hearing date hasn’t been scheduled.
