⚠︎ Federal law — affects every state A federal funding law signed in November 2025 (Public Law 119-37) narrows the legal definition of hemp, and a stopgap funding law signed September 2, 2026 (Public Law 119-103) split its start into two dates. On November 12, 2026, products containing cannabinoids that a cannabis plant cannot produce naturally, such as THC-O, fall outside it. The rest takes effect December 11, 2026, including the exclusion of chemically converted cannabinoids such as delta-8 made from CBD, a 0.3% limit measured as total THC (including THCA), and a limit of 0.4 milligrams of total THC per container. State rules apply on top of the federal law. Sources: Public Law 119-103, Sec. 2019 · Congressional Research Service · Akerman LLP
