Only 2 states (Idaho and Nebraska) maintain a full ban on both medical and recreational cannabis.
In 15 states, medical cannabis is legalized, and patients and caregivers can possess, grow, or use cannabis when recommended by their physicians.
In 9 states, some medical cannabis is allowed with limits on the THC content and strict limits on access.
For 24 states and the District of Columbia, recreational cannabis for adults aged 21 years or older is allowed in addition to medical cannabis (Figure 1).
On November 8, 2016, California approved Proposition 64, or the Adult Use of Marijuana Act, which legalized cannabis use by adults aged 21 years or older in private places.
Adults can possess for up to 1 ounce of cannabis, and grow up to 6 cannabis plants in a private residence for personal use.
Sales, excise, local, and growing taxes; retail store licensing and zoning; sales to minors; product labeling and quality; cultivation; and other regulations apply, and violations are subject to penalties (Figure 2).

Under Proposition 64, many of the criminal penalties for specific cannabis-related offenses were reduced or eliminated for adults or juveniles.
People convicted for violating cannabis laws prior to the passage of Proposition 64 are eligible to apply to a court to reduce or dismiss their prior conviction.
Those who are currently serving a sentence or on probation/parole can petition for re-sentencing, while those who have completed their sentence or are no longer under supervision can petition for re-designation of their crime.
From November 2016 to September 2022 in Los Angeles County (LAC), there were 2,170 petitions (8% of petitions in California) submitted to the courts for re-sentencing and re-designation. Among them, juvenile petitions accounted for 5% of petitions in LAC (Figure 3).
Among adult petitions, 901 (44%) were for re-sentencing, and 1,159 (56%) were for re-designation (Figure 4).
