What California law says about delta-8 THC

California first acted against intoxicating hemp through CDPH emergency regulations that took effect on 23 September 2024, requiring hemp foods, drinks and supplements to contain no detectable total THC, setting a minimum purchase age of 21 and limiting packages to five servings.³ The age and serving rules were made permanent in October 2025.³

AB 8, signed on 2 October 2025 as Chapter 248, Statutes of 2025, put the approach into statute.¹ It defines a “synthetic cannabinoid” to include “any form of tetrahydrocannabinol that was produced by the conversion of cannabidiol (CBD)”, and prohibits any person from selling or offering a product containing synthetic cannabinoids in the state. From 1 January 2026, hemp extracts used in food, drinks and supplements must be CBD or CBN isolate above 99% purity containing no THC.¹²

Because delta-8 sold as hemp is almost always made from CBD, it cannot lawfully be sold in California, including through licensed cannabis retailers. AB 8 also provides that intoxicating hemp violations carry the same civil and criminal penalties as illegal cannabis activity.² Adults 21 and over can still buy regulated cannabis products from licensed retailers.

Local rules

Many cities and counties prohibit cannabis retail entirely; licensed storefronts and delivery vary by locality.

Pending changes to watch

AB 8 moves hemp product oversight from CDPH to the Department of Cannabis Control on 1 January 2028; further DCC and CDPH rulemaking is expected before then.

How the federal hemp change affects California

Separate from California law, the federal definition of hemp is changing. Under the federal hemp redefinition passed in the FY2026 appropriations law, from 11 December 2026 hemp is measured by total THC, finished products are capped at 0.4 mg of total THC per container, and cannabinoids synthesised or manufactured outside the plant are excluded. Most delta-8 on the market is made by converting CBD, so most delta-8 products will fall outside the federal hemp definition from that date, whatever state law says.

A separate provision covering cannabinoids that the plant cannot produce naturally applies from 12 November 2026. Bills to delay or repeal the change are in congressional committees, but none had advanced as of September 2026. Our explainer on the federal hemp THC limit covers the detail.

Delta-8 in neighbouring states

Rules change at the state line. Here is how delta-8 THC is treated in the states bordering California, as of September 2026:

• Oregon: OLCC-approved products only, 21+
• Nevada: Banned as a synthetic cannabinoid
• Arizona: Licensed dispensaries only, 21+

Carrying products across state lines can break the law of the state you enter, and federal law also applies. Check the destination state’s rules first.

THCA in California

THCA is treated differently: in California it is Licensed cannabis retail only, 21+ as of September 2026. Read our guide to THCA law in California, or compare the two compounds in THCA vs Delta-8.

Frequently asked questions

Is delta-8 legal in California in 2026?

No. Since 1 January 2026, AB 8 prohibits selling any product containing synthetic cannabinoids, which it defines to include THC produced by converting CBD. Almost all delta-8 is made this way, so it cannot lawfully be sold by hemp shops or licensed cannabis retailers.

Can California dispensaries sell delta-8?

Not if it is made by converting CBD. AB 8’s ban on products containing synthetic cannabinoids applies to everyone, including Department of Cannabis Control licensees. Licensed retailers can sell cannabis products made from cannabis grown in the regulated supply chain to adults 21 and over.

Are hemp THC drinks legal in California?

No. From 1 January 2026, hemp extracts in food, drinks and dietary supplements must be CBD or CBN isolate above 99% purity with no THC. THC drinks can only be sold as cannabis products by licensed cannabis retailers to adults 21 and over.
