Federal restrictions enacted in late 2025 via Section 781 of a spending bill cap finished hemp-derived cannabinoid products at 0.4 mg total THC per container, with the effective date delayed to December 11, 2026. This change targets the hemp loophole from the 2018 Farm Bill and would render standard 5 mg THC seltzers non-compliant under federal rules governing interstate commerce. Industry groups are advancing the Beverage Regulatory Parity Act to permit up to 5 mg per serving under an FDA framework with age verification and testing requirements. Brands have responded with reformulated low-dose options and accelerated sales ahead of the deadline, while state-level rules continue to vary. Trader consensus reflects uncertainty over whether Congress will enact further delays or alternative legislation before December.
