California marijuana laws changed drastically with the decriminalization of possession (under 28.5 grams) and legalization of medical marijuana in 1996.
The state's marijuana laws were significantly relaxed once again in 2016 after voters approved Proposition 64, the Adult Use of Marijuana Act. Under this law, adults 21 and over may purchase, possess, and consume up to 28.5 grams of marijuana in their private residence or in an establishment licensed for marijuana consumption.
While most criminal sanctions for marijuana were lifted immediately after the general election, licensing to legally sell and produce recreational marijuana began in January 2018. There are also new cannabis taxes: a 15% excise and a cultivation tax.
The Medicinal and Adult-Use Cannabis Regulation and Safety Act provides the general framework for the regulation of commercial cannabis activity in California. This law requires anyone engaged in commercial cannabis activity to be licensed, and it allows local governments to control what activities are permitted in their jurisdiction.
As the lead agency in developing regulations for medical and adult-use cannabis in California, the Bureau of Cannabis Control (BCC) is responsible for licensing retailers, distributors, testing labs, and microbusinesses. The BCC provides an online licensing system where people can apply for a license, search for a license, or file a complaint.
While the new law requires medical marijuana dispensaries to obtain a new license, it generally leaves the existing medical marijuana laws intact. One change to medical marijuana laws is that certain medical marijuana sales are exempt from sales and use tax.

The legalization of marijuana in California -- despite its continued prohibition at the federal level -- has no doubt created some confusion. Keep in mind that there are still ways to be in violation of state law, such as possessing or growing more than is allowed or failing to comply with regulations governing commercial marijuana activities.
If you or a loved one is facing criminal charges under California's marijuana laws, even if your actions were unintentional, consider speaking with an experienced criminal law attorney to ensure that your rights are protected. If you are planning on opening your own legal cannabis shop, speaking with a local business law attorney can both save you time and money and ensure you are in full compliance with the law.
