A federal judge has upheld a new Iowa law regulating consumable hemp products, denying requests for a temporary restraining order from multiple THC companies citing vagueness and discrimination. The law, effective since July 1, limits THC content to 4 milligrams per serving and 10 milligrams per container, requiring clear labeling. The judge ruled that recent guidance from the Iowa Department of Health and Human Services clarified previously ambiguous terms, negating arguments of unconstitutionality. Despite the ruling, companies like Big Grove Brewery and Climbing Kites have expressed concerns about the impact on their businesses, including layoffs and product withdrawals. A lawsuit regarding the law remains pending, but the judge emphasized that the law's language is now clear enough to avoid arbitrary enforcement. The ongoing litigation reflects broader tensions over hemp regulation in Iowa as businesses adapt to the new standards.
