Vote yes on Proposition 19, the measure to legalize marijuana, and the unofficial state weed and largest cash crop will be controlled like alcohol, police will focus on serious crimes and California will get billions of dollars in new taxes. That's the pitch proponents make.
"It's a jumbled legal nightmare," opponents retort, disputing those claims and insisting that the measure would lead to stoned nurses in hospitals, drugged motorists on the road and more high teenagers.
Proposition 19, at three pages in the official voter information guide, is neither the longest nor the shortest initiative on the Nov. 2 ballot, but it would propel the state into unknown territory.
What is clear is that after midnight on election day, if the initiative has passed and you are at least 21 years old, you will be allowed under state law to smoke a joint in your home or other private place when no kids are around, keep a stash of up to an ounce and grow up to 25 square feet of marijuana plants.
That change, however, would not protect you from U.S. Drug Enforcement Administration agents, who could still enforce the federal Controlled Substances Act. And the new law could face a legal challenge, although the courts have ruled that states can decriminalize marijuana.
Beyond that, the potential effects of Proposition 19 become much murkier. The initiative would make California the first state to allow commercial cultivation and retail sales.
The measure's opponents say talk of legal sales and tax revenues is fanciful because the federal government wouldn't stand for it. U.S. Atty. Gen. Eric Holder promised this month to "vigorously enforce" federal drug laws, regardless of what California voters do. And former federal drug officials say it's unlikely any taxes would be paid because that would be admitting to a criminal violation.
But California's voters are not averse to casting their state into uncertainty. "It's part of California's culture," said Darry Sragow, a former political consultant who now teaches political science at USC. "You've got to be a bit adventurous to get all the way here. You've got to be a little bit of a risk taker."
When it comes to marijuana, voters were also warned in 1996 that Proposition 215, which allowed the drug to be used for medical reasons, would lead to chaos. The measure passed comfortably and has led to years of raids, trials and court battles, but the state's voters strongly support it.
About half of them now consistently tell pollsters they want to legalize marijuana, which opponents tacitly acknowledge by aiming their arguments not at legalization but at this particular initiative, ridiculing it as flawed. The argument signed by Sen. Dianne Feinstein in the voter guide begins: "Even if you support legalization of recreational marijuana, you should vote 'No' on Proposition 19."
Proponents say that prohibition has failed and that it's time for "a common sense approach to control marijuana," as retired San Jose Police Chief Joseph D. McNamara and others say in their voter-guide argument.
Opponents, backed by law enforcement organizations and the California Chamber of Commerce, challenge almost every claim made by proponents, starting with the title: The Regulate, Control and Tax Cannabis Act of 2010. They contend it would do no such thing.
The initiative leaves the issue of whether to allow legal sales up to the state's 481 cities and 58 counties, a wet-dry approach that mirrors how the state handles medical marijuana. But that makes it impossible to determine how carefully legal marijuana would be controlled.
If the past is any guide, most cities and counties would have nothing to do with it. Only 37 cities and 10 counties allow medical marijuana dispensaries, according to Americans for Safe Access, an advocacy group. In some places, notably Los Angeles, city officials lost control over them.
Oakland, the political hub of the state's marijuana legalization movement, would almost certainly be the first place to wrestle with regulations. A local initiative passed six years ago requires the city to allow sales "as soon as possible under California law."
San Francisco and Santa Cruz have passed legislation calling on the state to allow legal sales. And Oakland, Humboldt County, Berkeley and West Hollywood have endorsed Proposition 19.
"I think we will proceed cautiously," said West Hollywood Councilman John Duran, who noted that the city helped set up one of the state's first cannabis clubs, which closed in 2001 after a DEA raid. "We'd have to decide once again if this little city is ready to take on the United States. We did it before."
This city-county approach also makes it anyone's guess how much might be raised in tax revenues. Proposition 19 promises billions of dollars, and proponents cite a figure of $1.4 billion, but that is an estimate for a legislative bill that would legalize pot sales statewide.
