A federal measure that would sharply restrict hemp-derived THC products threatens to eliminate a multibillion-dollar market spanning gummies, beverages, vape oils and smokable cannabis. The short-term government-funding bill signed by President Donald Trump last month delayed the ban’s effective date from Nov. 12 to Dec. 11, giving Congress more time to consider rules including age limits, package-level THC caps and restrictions on imported cannabis compounds. The ban would limit hemp products to 0.4 milligrams of THC per container, a threshold industry representatives say could eliminate impairing products and even some non-impairing CBD goods. Whitney Economics estimates the measure could reduce retail revenues by $28.3 billion, displace 225,000 jobs and cut potential state sales-tax revenue by $2.1 billion. Producers such as Kentucky’s Cornbread Hemp say they could accept a 5-milligram limit but would not survive the proposed cap. Supporters say hemp THC products pose safety risks and create unfair competition for regulated marijuana businesses, while advocates argue that some products could move into legal state markets or operate under stricter hemp rules.
