One of the more important recently decided Commerce Clause cases dealt with whether the federal government could enforce federal anti-drugs in California after voters there decided to legalize marijuana for medicinal purposes. (see Raich v. Gonzalez) The answer given by the U.S. Supreme Court was yes, the Feds can arrest people for using marijuana even if users are doing so pursuant to California state law. The question many students must have is: so is it still legal to purchase marijuana in California, under state law, for medicinal purposes? The quick answer is under state law YES, but people who use the drug still run the risk of being arrested by federal agents under federal law. But it gets even more confusing. The San Diego Union-Tribune newspaper recently reported that San Diego County is suing the State of California to repeal the medical marijuana laws. Lawyers for San Diego and San Bernardino counties will argue that the state cannot force counties to issue identification cards to qualified medical marijuana patients because the drug is illegal under federal law.
So, under California law it is the local government (in this case county government) that must help carry out the medical marijuana law, but the counties are beginning to question whether this is wise (and lawful) in light of the aforementioned U.S. Supreme Court decision. Ah, the joys of federalism.
UPDATE - A California court has ruled that California's medical marijuana laws do not violate federal law saying, "The purpose of the (federal law) is to combat recreational drug use, not to regulate a state's medical practices." It is possible that this ruling will be appealed to California Supreme Court.
