As of November 2016, Proposition 64 legalized the recreational use of marijuana in California. Adults over the age of 21 can now legally use, possess and share cannabis, as well as grow it privately in their homes. While the laws have been passed, there are still some stiff regulations imposed on when, where and how adults can enjoy the use of marijuana.

Adults growing cannabis within their home must do so in a "fully enclosed and secure" way. Households are limited to growing six plants at one time.

Adults also cannot smoke or ingest marijuana in public. Over time, Proposition 64 will allow licensed on-site consumption once licensed vendors and stores begin to appear throughout the state.

There are also regulations placed upon the type of edibles allowed. Legal edibles must be low-dose with each section holding no more that 10 milligrams of THC. Edibles must be in childproof packaging and can not be branded in any fashion that may appeal to children in order to avoid accidental ingestion.

While the use of cannabis in California is legal, similar to the laws of alcohol it is illegal to operate a vehicle, boat, aircraft or any type of vessel while under the influence.

The legalization of marijuana in California will also affect those with previous cannabis-related offenses. Criminal penalties will undergo change, and some offenders will have the opportunity to get out of jail early. Those under the age of 18 will not be punished with jail time but will be required to attend drug counseling and community service in the event that they are caught with cannabis.

Many laws and regulations will progress and undergo change as time goes on. The evolution of the cannabis industry in California is predicted to follow the footsteps of their wine industry, that also made a triumphant comeback following the prohibition.
