Californians who use medical marijuana outside of work would be protected from job dismissal due to medical marijuana use under a bill that has been introduced by state Sen. Mark Leno, D-San Francisco. The bill, SB129, would make it illegal for an employer to consider either a worker's status as a registered patient or a positive drug test when making hiring and firing decisions. The bill would not change existing laws that bar employees from using medical marijuana at the workplace or during work hours.
