FDA Faces Deadline for Cannabis Guidance on Hemp THC Serving Sizes

Key Takeaway

The FDA faced a statutory deadline to publish cannabinoid lists and issue guidance on 'container' definitions that will determine THC serving sizes under the hemp recriminalization law passed in late 2025. The underlying law requires that hemp products contain less than 0.4 percent total THC per container, but leaves the practical definition of 'container' ambiguous for beverages, gummies, tinctures, and other product formats. The FDA's guidance will determine whether many currently-legal hemp products remain on shelves after the November 2026 effective date. For cannabis operators, the guidance outcome directly affects hemp competition: narrow container definitions could eliminate most competing hemp products, while broad definitions could preserve significant gray-market competition.
