Cannabis Legalization and Regulation in California

‍

California legalized adult-use cannabis in 2016 through Proposition 64 (the Adult Use of Marijuana Act), with commercial sales beginning in January 2018. Adults 21 and older may legally possess up to 1 ounce of cannabis flower or 8 grams of concentrates. Home cultivation is permitted with up to six plants per household, regardless of the number of adults living there, provided plants are kept out of public view. Public consumption is prohibited unless in licensed consumption lounges, and impaired driving remains illegal.

‍

The cannabis industry in California is regulated by the Department of Cannabis Control (DCC), which oversees licensing for cultivators, manufacturers, distributors, testing labs, microbusinesses, retailers, and event operators. Local governments retain control, and many jurisdictions restrict or prohibit retail cannabis businesses, creating a patchwork of access across the state.

‍

California’s medical cannabis program, first established in 1996 under Proposition 215, continues to operate alongside adult-use. Registered medical patients may purchase larger quantities, are exempt from certain taxes, and have broader cultivation rights if medically necessary. Medical identification cards are available through county health departments.

‍

Hemp and hemp-derived products are legal in California if they contain no more than 0.3% THC. The state has adopted strict regulations on hemp-derived cannabinoids, including delta-8 THC, requiring such products to go through the licensed cannabis supply chain. All cannabis and hemp products must meet testing, labeling, and packaging standards before sale.

‍

For cannabis operators, California represents the nation’s largest and most competitive market. Banking and financial service providers require strict compliance, including verified licensing, ownership records, tax IDs, financial statements, and operating agreements. Due to the heavy cash flow of cannabis businesses, banks expect armored transport services, reconciled deposit systems, AML/BSA monitoring, and audit-ready accounting. California imposes both state and local cannabis excise and sales taxes, making accurate recordkeeping and reporting essential for financial stability.
