Delta-8 and Hemp THC Laws in Iowa

Iowa regulates hemp-derived THC products as 'consumable hemp products' (eaten, drunk or absorbed). Since 2024, such a product may contain no more total THC than the lesser of 0.3% on a dry weight basis or 4 milligrams per serving and 10 milligrams per container; hemp products above the limits are not exempt from the controlled substances law, and the Schedule I hemp exclusion counts THC 'inclusive of any isomers, derivatives, and analogs, whether naturally occurring or synthesized'. Manufacturers and sellers must register with the Department of Health and Human Services. Selling or giving a consumable hemp product to anyone under 21 is a simple misdemeanor, and a person under 21 who consumes, possesses or buys one faces a civil penalty and community service. Possessing or selling hemp or hemp products intended to be inhaled (smoked or vaped) is a serious misdemeanor unless federal law authorizes inhalation.
