What Connecticut law says about delta-8 THC

Connecticut’s approach comes from Public Act 23-79, effective 1 July 2023. It defines “THC” to include delta-7, delta-8, delta-9 and delta-10 THC “regardless of the source”, and creates the category of a high-THC hemp product: a manufactured hemp product whose total THC exceeds 1 mg per serving or 5 mg per container for edibles and topicals, 1 mg per serving or 25 mg per container for tinctures, or 25 mg per container for concentrates and vape oils. High-THC hemp products are included in the legal definition of cannabis.¹

As a result, a typical delta-8 gummy or vape is legally cannabis in Connecticut and may only be sold by businesses licensed by the Department of Consumer Protection (DCP) to adults 21 and over. Products below the thresholds remain hemp and are regulated separately, including a “moderate-THC hemp product” category for items with 0.5 mg to 5 mg total THC per container.²

Public Act 26-8, signed on 20 May 2026 with most provisions effective 1 October 2026, renames marijuana as cannabis in state law, raises the THC limit for infused beverages sold in package stores from 3 mg to 5 mg per container (10 mg in cannabis retailers), and removes potency limits on cannabis concentrates. It does not change the high-THC hemp thresholds.²³

Local rules

Municipalities may use zoning to prohibit or limit cannabis establishments.

Pending changes to watch

Most Public Act 26-8 provisions take effect on 1 October 2026; DCP policies to implement them are expected.

How the federal hemp change affects Connecticut

Separate from Connecticut 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.

Timeline of recent changes

• 20 May 2026: Public Act 26-8 signed, raising the infused beverage THC limit and updating cannabis and hemp rules (mostly effective 1 October 2026).
• 1 July 2023: Public Act 23-79 took effect, treating high-THC hemp products, including most delta-8 items, as cannabis.

Delta-8 in neighbouring states

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

• New York: Banned in hemp products
• Massachusetts: Banned as a hemp product
• Rhode Island: Banned in hemp products

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 Connecticut

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

Frequently asked questions

Can gas stations in Connecticut sell delta-8?

Not above very low doses. Any hemp product with more than 1 mg THC per serving or 5 mg per package (25 mg for vapes and tinctures) is legally cannabis, and delta-8 counts as THC. Those products may only be sold by DCP-licensed cannabis retailers to adults 21 and over.

Is delta-8 a controlled substance in Connecticut?

Delta-8 counts as THC under Connecticut law regardless of its source. Products over the high-THC hemp thresholds fall within the legal definition of cannabis, so they are legal for adults 21 and over only when bought from licensed cannabis establishments.

What changed for THC products in Connecticut in 2026?

Public Act 26-8, signed on 20 May 2026, raised the THC limit for infused beverages sold in package stores from 3 mg to 5 mg per container, allowed up to 10 mg in cannabis retailers, and made other cannabis and hemp changes, mostly from 1 October 2026.
