Legal Question in Employment Law in California

Of course. Companies are obligated to maintain a drug free workplace, card or not.

CA had made possession of small amount of marijuana an infraction crime. CA has an actual official medical marijuana card issued upon doctor�s certification of medical need. Local �dispensaries� will sell you a card, which is not CA official. Both are frequently accepted by local police to avoid an arrest for small possession. Neither is honored by �the feds�. It is a Politically Correct fiction in California only, not binding upon federal law enforcement or courts. You risk federal felony prosecution for possession.
