At least one poll shows voters would support lifting the pot prohibition, which would make the state of 40 million the first in the nation to legalize marijuana. Such action would also send the state into a headlong conflict with the U.S. government while raising questions about how federal law enforcement could enforce its drug laws in the face of a massive government-sanctioned pot industry. The state already has a thriving marijuana trade, thanks to a first-of-its-kind 1996 ballot measure that allowed people to smoke pot for medical purposes. But full legalization could turn medical marijuana dispensaries into all-purpose pot stores, and the open sale of joints could become commonplace on mom-and-pop liquor store counters in liberal locales like Oakland and Santa Cruz. Under federal law, marijuana is illegal, period. After overseeing a series of raids that destroyed more than 300,000 marijuana plants in California's Sierra Nevada foothills this summer, federal drug czar Gil Kerlikowske proclaimed, "Legalization is not in the president's vocabulary, and it's not in mine." Awesome.
