The 2019 lawCannabis Industry Act allows adults 21 and over to hold one ounce of cannabis, eight grams of concentrate or infused products containing up to 800 mg THC.[@industry19,current] It also protects possession of cannabis produced by the permitted personal plants on the premises where it was grown.[@industry19] No current cannabis-specific penalty for possession above those limits was found: the 2019 Act declassified cannabis and repealed the old marijuana tiers, while the general controlled-substances provision is not a clean fit.[@ucsa]

No operational hemp licensing regime. The cannabis definition has no hemp THC threshold, and low-THC hemp is dealt with through a final Guam Hemp Plan dated November 2023 that follows the federal 0.3 per cent line, but implementing rules were still draft in September 2025.[@hempPlan] Shops sell hemp-derived THC products under federal law; federal changes in late 2026 are expected to remove most intoxicating hemp products from the federal hemp definition.[@hempFederal]
