Adult Usage Act (Proposition 64)

Last updated: November 17, 2021

What Does Adult Usage Act (Proposition 64) Mean?

The Adult Usage Act was a 2016 California voter initiative meant to legalize marijuana. It was alternately known as “The Adult Use of Marijuana Act,” “Proposition 64” and formally known as the “Control, Regulate, and Tax Adult Use of Marijuana Act.”

The Adult Usage Act was overwhelmingly approved by the citizens of California and became law on November 9, 2016, immediately after passing.

Though it became law in 2016, the act allows for a delay in implementation. By January 1, 2018, the state will begin issuing licenses; they are not required to begin prior, but can if they so choose or are ready to commence.


Maximum Yield Explains Adult Usage Act (Proposition 64)

The Adult Usage Act (Prop 64) act allows for individuals over the age of 21 to grow up to six marijuana plants in their homes, but this is limited to six plants per household, not per individual. Recreational marijuana is taxed under this act at the state level by 15 per cent. Local municipalities can then add additional taxes on recreational marijuana. Medical marijuana is exempt from taxation under this act.

Other exceptions to this act include limiting the amount of marijuana that any individual may possess or transport at one time. Individuals over 21 can give, possess, purchase, or process (all without compensation) up to 28.5 grams of non-concentrated cannabis at any time or up to 8 grams of concentrated cannabis.
