On November 4, 2014,
California Proposition 47 was passed. Also known as the Safe Neighborhood and Schools Act, Proposition 47 made the punishment for the possession of controlled substances in the state of California drop down from a felony to misdemeanor.
This law's reclassification of possession related felonies as misdemeanors made it possible for those priorly convicted to petition their felony charges which for some means shorter sentences and others less restrictive charges on their record.
On May 4, 2016, the group sponsoring the initiative announced that it had collected over 600,000 signatures for the proposal; enough to get it on the 2016 ballot. On June 28, the measure was certified by the Secretary of State for the November ballot. On July 1, the Secretary of State released a list of propositions with AUMA listed as Proposition 64, then later in the day renumbered it to 63; and, on July 2, released a final list restoring it to Proposition 64.

, the measure changes California law to legalize the possession, cultivation, and sale of marijuana. Individuals over age 21 are allowed to possess, cultivate, and sell marijuana; the state regulates commercial activities related to commerce for recreational use; a 15% excise tax and an additional $9.25 per ounce of flower or $2.75 per ounce of leaf will be collected; and possession and cultivation of certain amounts for personal use is legalized statewide.
The Adult Use of Marijuana Act (AUMA) (Proposition 64) provides an array of opportunities ranging from economic stimulation of several markets and industries to financial relief of the criminal justice system, which are over-burdened with backlogged and pending cases for non-violent cannabis offenders. Revenue paid into the new California Marijuana Tax Fund will allocate 60% of outflows to youth programs, 20% to environmental damage clean-up, and 20% to public safety.
Under Prop 64, new state regulation laws will require stringent product development systems to establish distributional industry standards regarding testing, packaging, and labeling.
Prop 64's new state regulations provide a platform for a fully transparent, highly efficient seed-to-sale tracking system through the newly created State Regulatory Agency—the Bureau of Marijuana Control—formerly known as the Bureau of Medical Cannabis Regulation.
Additionally, the Medical Marijuana Industry will be regulated by several other state agencies: the

California has the biggest legal cannabis market in the United States due to high population density and high cultivation rates. California NORML called the proposition's vote "crucial" and said, "Although Prop 64 has drawbacks and isn’t all it should be from a consumer perspective, on balance it offers significant improvements over California’s current laws and would be a powerful boost for cannabis reform nationwide."

'' (Salt Lake City) expressed concern over a "potential problem when it comes to minorities and recreational marijuana" if the measure passed. ''Deseret News'' cited an NPR report from Colorado to conclude that in California, white youth arrests could fall faster than those of minorities, or minority arrests could even increase due to lack of minority access to legal sales and nonwhite ownership of cannabis businesses, worsening the effect of "systemic racism" in pursuing drug crime.
California Proposition 64 helps to remedy marijuana related incarceration rates considerably. However, some argue that the passing of the MORE Act is a necessary next step down the path of decriminalization of the substance, as it would remove cannabis from the controlled substances list and declassify marijuana as a schedule 1 drug.
The MORE Act could potentially help to remedy some of the racial disparities within America's criminal justice system that proposition 64 does not address. According to Forbes roughly 40000 remain behind bars due to cannabis related charges as of 2020. With the racial gap widening over the past 20 years after the War On Drugs campaign took off, a jump from 3:1 to 5:1 between Black and White incarceration rates occurred.[ In 2014, black people made up roughly 14% of the 127,000 drug charges in California.][
While Proposition 64 decriminalizes the possession of up to 1 ounce of marijuana, the effects are not immediately felt by those with charges made prior to the passing of this law. Those with prior convictions must still petition for shorter sentences, release, or a change from felony to misdemeanor on their records.
The MORE Act calls for a more transparent system in regards to cannabis companies employer/employee demographics which might help to mitigate issues of monopolization within California's cannabis industry that arouse after proposition 64 was passed in 2016.][
