The San Mateo County Times reports that San Francisco police, who patrol San Francisco International Airport, say they allow card-holding medical marijuana patients to carry up to 8 ounces of dried cannabis when traveling. The SFO policy follows the guidelines police use within the city of San Francisco.
Of course, just because passengers are allowed to take their marijuana out of the Bay Area does not give them full immunity from prosecution, as more than 30 states ban medical marijuana. If a Bay Area traveler lands in a place where the drug is illegal, they could be prosecuted by state authorities.
Alameda County deputies notify passengers flying out of Oakland that they could be violating the law if they land in one of the many states that ban medical marijuana. But they have never called ahead to notify police on the other end.
