Proposition 19, if approved by voters, will legalize various marijuana-related activities, allow local governments to regulate these activities, permit local governments to impose and collect marijuana-related fees and taxes, and authorize various criminal and civil penalties. Proposition 19 was certified for the November statewide ballot on March 24, 2010. The official proponents of the measure are Richard Lee and Jeffrey Wayne Jones. Tax Cannabis 2010 is the official advocacy group for the initiative.
12 California cities have local ballot measures on their November 2 ballot that would allow them to tax recreational marijuana if Proposition 19 passes.

Results via California Secretary of State Election Results.
Current legal status
Gov. Arnold Schwarzenegger signed SB 1449 on October 1, 2010. Effective January 1, 2011, SB 1449 turns the possession of less than an ounce of marijuana from a criminal misdemeanor into an civil infraction.
Medical marijuana is already legal in California, due to the enactment of Proposition 215 in 1996.
The use, sale and cultivation of marijuana is currently illegal under federal law throughout the United States.
Text and title
Allows people 21 years old or older to possess, cultivate, or transport marijuana for personal use. Permits local governments to regulate and tax commercial production and sale of marijuana to people 21 years old or older. Prohibits people from possessing marijuana on school grounds, using it in public, smoking it while minors are present, or providing it to anyone under 21 years old. Maintains current prohibitions against driving while impaired.
Summary of estimated fiscal impact:
Savings of up to several tens of millions of dollars annually to state and local governments on the costs of incarcerating and supervising certain marijuana offenders. Unknown but potentially major tax, fee, and benefit assessment revenues to state and local government related to the production and sale of marijuana products.
Effects of the bill
|Marijuana on the ballot in 2010|
- Persons over the age of 21 may possess up to one ounce of marijuana for personal consumption.
- May use cannabis in a non-public place such as a residence or a public establishment licensed for on site marijuana consumption.
- May grow marijuana at a private residence in a space of up to 25 square feet for personal use.
Local government regulation
- Local government may authorize the retail sale of up to 1 ounce of marijuana per transaction, and regulate the hours and location of the business.
- Local government may authorize larger amounts of marijuana for personal possession and cultivation, or for commercial cultivation, transportation, and sale.
- Allows for the transportation of marijuana from a licensed premises in one city or county to a licensed premises in another city or county, without regard to local laws of intermediate localities to the contrary.
Local taxes and fees
- Allows the collection of taxes specifically to allow local governments to raise revenue or to offset any costs associated with marijuana regulation.
Criminal and civil penalties
- Maintains existing laws against selling drugs to a minor and driving under the influence.
- Maintains an employer's right to address consumption of cannabis that affects an employee's job performance.
- Maintain existing laws against interstate or international transportation of cannabis.
- Any person who is licensed, permitted or authorized to sell cannabis, who knowingly sells or gives away cannabis to someone under the age of 21 results in them being banned from owning, operating, or being employed by a licensed cannabis establishment for one year.
- Any person who is licensed, permitted or authorized to sell cannabis, who knowingly sells or gives away cannabis to someone older the age of 18 but younger than 21, shall be imprisoned in county jail for up to six months and fined up to $1,000 per offense.
- Any person who is licensed, permitted or authorized to sell cannabis, who knowingly sells or gives away cannabis to someone age 14 to 17, shall be imprisoned in state prison for a period of three, four, or five years.
- Any person who is licensed, permitted or authorized to sell cannabis, who knowingly sells or gives away cannabis to someone under the age of 14, shall be imprisoned in state prison for a period of three, five, or seven years
In the time leading to 2010, California's state government's budget deficit has grown to be the largest of all American states. The California legislature has estimated that taxing the previously untaxed domestically grown $14 billion cannabis market would produce $1.4 billion a year, Taxing cannabis, supporters say, could be a smart way to help alleviate pressure on the state budget.
- Result in significant savings to state and local governments, potentially up to several tens of millions of dollars annually due to reduction of individuals incarcerated, on probation or on parole.
- Cells currently being used to house cannabis offenders could be used for other criminals, many of whom are now being released early because of a lack of jail space.
- Reduction in state and local costs for enforcement of cannabis-related offenses and the handling of related criminal cases in the court system, providing the opportunity for funds to be used to enforce other existing criminal laws. The RAND Corporation has found that law enforcement costs for cannabis enforcement are approximately $300 million a year.
- Potential increase in the costs of substance abuse programs due to speculated increase in usage of cannabis, possibly having the effect of reducing spending on mandatory treatment for some criminal offenders, or result in the redirection of these funds for other offenders.
- The measure could potentially reduce both the costs and offsetting revenues of the state's medical marijuana program as adults over 21 would be less likely to participate in the existing program as obtaining cannabis would be easier, thus making use of existing medical marijuana program unnecessary.
- There would be a reduction in fines collected under current state law but a possible increase in local civil fines authorized by existing local laws.
- The cumulative effect on fines is largely unknown.

Arguments in favor
If passed by the voters on November 2, 2010, supporters argue that Proposition 19 will:
- Create between 60,000 and 110,000 new jobs in California
- Generate between $1.2 billion and $1.4 billion in new direct tax revenue annually
- Expand California's economy by between $16 billion and $23 billion annually
- Free up law enforcement resources to focus on violent crime and property crime.
- Reduce environmental damage to California's public lands from illegal grow operations.
- Reduce state expenditures by over $200 million in law enforcement costs for arrests, prosecutions and imprisonment of cannabis users. 
- Reduce funding to drug cartels, who currently get about 70% of their revenue from illegal cannabis sales
- Improve the relationship between police and the communities they serve. 
- Reduce alcohol's cost to society by allowing adults to choose a safer alternative
Four campaign committees are officially registered as supporting a "yes" vote on Proposition 19. They are:
- "Yes on 19. Tax Cannabis 2010. Sponsored by S.K. Seymour LLC, a Medical Cannabis Provider, dba Oaksterdam University, a Cannabis Educator"
- "Drug Policy Action Committee to Tax and Regulate Marijuana - Yes on Prop. 19"
- "Credo Victory Fund - Yes on 19"
- "Students for Sensible Drug Policy, David Bronner, Adam Eidinger, and Alan Amsterdam Committee to Regulate Cannabis - Yes on 19"
Larger donors to one or more of these committees through October 27 include:
Note: The donations listed above do not include Oaksterdam University/Richard Lee's contributions in 2009 to collect the signatures to qualify Proposition 19 for the ballot, an effort that cost approximately $987,000.

|Voting on Marijuana|
|Not on ballot|
The main themes of the arguments made against Proposition 19 by its opponents in the official California Voter Guide are:
- The way Proposition 19 is written, it "will prevent bus and trucking companies from requiring their drivers to be drug-free. Companies won’t be able to take action against a 'stoned' driver until after he or she has a wreck, not before."
- Enactment of Proposition 19 will endanger school children because "A school bus driver would be forbidden to smoke marijuana on schools grounds or while actually behind the wheel, but could arrive for work with marijuana in his or her system."
- "Proposition 19 could cost our K–12 schools as much as $9.4 billion in lost federal funding", according to public school superintendent John Snavely, Ed.D., because the schools wouldn't be able to comply with federal government grant requirements.
- Employers in California that bid for public contracts and grants that are ultimately funded by the federal government would no longer be eligible for those contracts and grants if Proposition 19 passes because Proposition 19 would prevent them from being able to "effectively enforce the drug-free workplace requirements outlined by the federal government". This would result in further harm to California businesses and their workers, according to the California Chamber of Commerce: "Proposition 19 creates special rights for employees to possess marijuana on the job, and that means no company in California can meet federal drug-free workplace standards, or qualify for federal contracts. The California State Firefighters Association warns this one drafting mistake alone could cost thousands of Californians to lose their jobs."
- Proposition 19 doesn't include a definition of "driving under the influence" and as a result, it is opposed by the California Police Chiefs Association because it could lead to a situation where a driver can legally drive "even if a blood test shows that they have marijuana in their system."
- Employers would not be able to pre-emptively remove workers who smell of marijuana use from sensitive jobs such as operating heavy machinery or running medical lab tests but would instead have to wait to take action until after an accident occurs.
Other arguments that have been made against Proposition 19 include:
- Problems exist from tobacco and alcohol being legal, why add another to the mix?
- Due to California's strong law against legislative tampering with what voters enact via the ballot initiative process, if Proposition 19 is passed and is later found to have unexpected negative secondary consequences, the California State Legislature will be unable to effectively address those problems.
- Legalization would likely bring with it additional substance abuse in the state, and the long-term public costs associated with that could vastly exceed the amount of new revenue legalized marijuana might bring in."
- Allegations that the act does not do as the ballot title specifies and is misleading as written.
- Prop 19 would make it more difficult for police to perform warrantless searches
Five campaign committees have registered with the California Secretary of State to spend money to defeat Proposition 19. They are:
- "Nip It In the Bud: No on Prop. 19"
- "Crusades for Patients Rights - No on Prop 19 Sponsored by Canna Care"
- "Public Safety First - No on Prop. 19, A Project of People Against Prop. 5 Deception"
- "Citizens Against Legalizing Marijuana"
- "Committee Against the Legalization of Marijuana, A Committee Against Prop. 19"
Through October 27, larger donations to the "No on 19" campaign effort have come from:
|California Police Chiefs Association||$49,999|
|San Manuel Band of Mission Indians||$25,000|
|California Narcotics Officers Association||$20,500|
|California Beer & Beverage Distributors||$10,000|
Although the $10,000 contribution from the California Beer & Beverage Distributors is very small by California ballot proposition standards of recent years, it nevertheless attracted a press release from Steve Fox, the government relations director for the Marijuana Policy Project saying, "Unless the beer distributors in California have suddenly developed a philosophical opposition to the use of intoxicating substances, the motivation behind this contribution is clear. Plain and simple, the alcohol industry is trying to kill the competition."
Marijuana is illegal under federal laws. If marijuana becomes legal in California under state law, it will still be federally illegal. The U.S. Supreme Court has previously ruled that federal agents can arrest medical marijuana users and growers even though Proposition 215 makes that behavior legal in California.
Legal scholars, considering what might happen if marijuana is fully legalized in California, have said:
- The federal government would not be able to require California law enforcement agencies to help them enforce the federal law.
- Federal law enforcement officers can continue to arrest and prosecute the use, sale, possession or production of marijuana in California.
- As a matter of practice, most marijuana arrests are made by state law enforcement officers. In 2008, there were 847,000 marijuana-related arrests throughout the country. About 6,300 of these arrests were performed by federal agents. That's less than 1% of all marijuana arrests.
Drug Free Schools and Community Act:
At least some universities within the State have said that they would continue to prohibit marijuana on campus because the federal Drug Free Schools and Community Act (DFSCA) requires that they certify that campus policies prohibit illegal drugs. Drugs presumably would be deemed illegal based upon federal standards. Failure to comply with the DFSCA can lead to a loss of all federal funds.

Coattails and turnout
Democratic pollster Anna Greenberg conducted a poll in August 2010 to assess whether having Proposition 19 on the ballot would motivate some voters to vote who might not otherwise do so. Greenberg found that 25% of Democrats in California were 'extremely interested' in voting in the 2010 elections for Governor of California (Brown vs. Whitman) and U.S. Senator (Boxer vs. Fiorina). However, 38% of Democrats were 'extremely interested' in voting on Proposition 19. In Greenberg's poll, there was no similarly large gap in interest levels in voting on governor or senator, and voting on Prop. 19.
Opinion of Law Professors
Law professors from across America wrote an open letter to California voters to express their support for Proposition 19.
Law professors who signed the letter include:
- Jonathan H. Adler, Case Western Reserve University School of Law, Cleveland, Ohio
- Ty Alper, University of California, Berkeley, School of Law, Berkeley, CA
- Hadar Aviram, University of California, Hastings College of the Law, San Francisco, CA
- W. David Ball, Santa Clara Law, Santa Clara, CA
- Randy Barnett, Georgetown University Law Center, Washington, DC

"Yes on 19"
- The Financial Times: "Rather than stopping violence, prohibition fuels it. Most drug violence is caused by turf wars, not users committing petty crimes to finance their habit. Traffickers cannot rely on the courts to resolve disputes so they swap lawyers for guns. Mexico’s increasingly bloody drug war – some gangsters are better armed than the state – has cost 28,000 lives since 2006. By raising prices, prohibition allows drug barons to reap high profits. Simply smuggling a kilo of marijuana from Mexico to the US raises its price from $80 to $2,000."
- The Orange County Register: "Legalizing marijuana use for adults is a significant step away from nanny-state policies and all the crime, corruption and violence that accompany marijuana prohibition, so some caution about such an important move is understandable. But the impact on employment polices, driving laws and the responsibilities of local government are not sufficient to justify rejection of this proposal."
- The Santa Barbara News-Press: "It is time to legalize marijuana in California."
- The Santa Cruz Weekly: "The Regulate, Control and Tax Cannabis Act of 2010 will provide the state with significant tax revenue...It's time for this foolish prohibition to be abolished."
- The Stanford Review: "As both a moral and tangible matter, the harm inflicted on innocent victims by drug gangs is far worse than the harm that drug users willingly inflict on themselves and the abstract harm that marijuana causes to society. The logical next step after this realization is to let legitimate businesses sprout up to supply Californians’ demand for marijuana, instead of continuing our policy of enforcing violent drug gangs’ monopolies on the marijuana market."
- The Victoriaville Daily Press: "This is not an easy call, but it makes more sense than continuing to expend billions of tax dollars on what is increasingly becoming a futile effort to outlaw marijuana use. It has never worked, and it’s time to try a new tactic. Vote yes on 19."
"No on 19"
- Bakersfield Californian: "Prop.19’s backers think a legalized, controlled marijuana industry could eventually be regulated and taxed to the tune of as much as $1.4 billion per year to help fund health care, job creation, infrastructure and other needs. But the initiative doesn’t offer guidance on how this might be coordinated - - in fact the taxation element isn’t even written into the proposition…"
- The Herald (Monterey County): "We fear that a California-only pot industry operating under inconsistent and even contradictory rules would create serious crime problems of its own. Proposition 19 doesn't set a measurable standard for driving under the influence of marijuana, and it could make it much more difficult for employers to bar employees from using marijuana even if it might undermine their ability to work safely."
- Lompoc Record: "This measure is too flawed to be taken seriously."
- Long Beach Press-Telegram: "Prop. 19 is flawed, flies in the face of federal law, is opposed by major law-enforcement officials and politicians and would be abused by underage consumers. Estimates of tax revenue are wildly exaggerated."
- Los Angeles Times: "Proposition 19 is poorly thought out, badly crafted and replete with loopholes and contradictions."
- Los Angeles Daily News: "The real question of this initiative is whether California wants to take on the federal government and allow any and every city in the state to make up its own rules about selling, manufacturing and transporting an illegal substance. And the Daily News thinks the answer to the question is an emphatic 'no.' The Regulate, Control and Tax Cannabis Act of 2010 is a poorly crafted initiative that would set the scene for a regulatory nightmare in California."
- Modesto Bee: "Proposition 19 is poorly drafted and deeply flawed, filled with loopholes and ambiguities that would create a chaotic nightmare for law enforcement, local governments and businesses."
- Sacramento Bee: "The measure on the Nov. 2 ballot is full of worrisome loopholes and ambiguities that would create a chaotic nightmare for law enforcement, local governments and businesses. It is so poorly drafted, in fact, that it almost makes you wonder: What were they smoking?"
- San Diego Union-Tribune: "Don’t take the bait. Don’t turn California into the nation’s drug dealer."
- A joint editorial in the Pasadena Star-News, San Gabriel Valley Tribune, and Whittier Daily News: "The best way to look at Proposition 19, which would legalize the sale and possession of marijuana for adults, is to paint a picture of the state if the measure were to pass: The guy in the cubicle next to you at work is stoned. There's an increased likelihood the driver of the car in the next lane on the freeway is under the influence of pot. Commercial entities openly selling pot in storefronts near where you shop, or perhaps in your child or grandchild's college dormitory…This is not our vision of a bright California future."
- Santa Rosa Press Democrat: "Proposition 19 is so poorly worded and filled with loopholes that it’s likely to create more confusion than clarity. And, as with Proposition 215, which legalized medicinal uses of marijuana, it would still leave California law in conflict with federal law, creating more regulatory and policy gridlock at all levels of government."
- San Bernardino Sun: "Our editorial board agreed unanimously that Proposition 19…is no way to legalize marijuana. It is poorly written, conflicts with too many federal laws and would pose dangers - physical and financial - to the citizens of California."
Path to the ballot
- See also: California signature requirements
Three different groups filed proposed initiatives with the California Secretary of State for 2010 ballot measures that would legalize marijuana, but the Regulate, Control and Tax Cannabis Act of 2010 is the only one that qualified for the ballot.
- Richard Lee and Jeffrey Wayne Jones filed the language for 09-0024 on July 27, 2009. This measure, known as the Regulate, Control and Tax Cannabis Act of 2010, had collected close to 700,000 signatures by the end of 2009 and went on to successfully file sufficient signatures and qualify for the ballot as Proposition 19.
- Joe Rogoway, Omar Figueroa and James J. Clark filed the language for 09-0022 on July 15, 2009. They referred to their measure as The Tax, Regulate, and Control Cannabis Act of 2010. This measure was withdrawn on 2/4/2010 and was subsequently listed as "failed" on the Secretary of State website. 
- John Donohue of "Californians for Common Sense" filed the language for 09-0025 on August 4, 2009. He referred to his measure as the Common Sense Act of 2010. This initiative also failed to qualify. 
Supporters of the Regulate, Control, and Tax Cannabis Act of 2010 turned in over 700,000 qualifying signatures to election authorities on January 28, 2010, versus a requirement of 433,971 signatures.
Supporters of the Regulate, Control, and Tax Cannabis Act of 2010 campaign launched their signature-collection campaign in September in San Francisco at the annual gathering of the National Organization for the Reform of Marijuana Laws.
