The Iowa Department of Agriculture and Land Stewardship is in the process of developing a state plan to license and regulate the production of hemp. It was submitted to the USDA for approval on Dec. 11, 2019. It is not legal to grow, possess, buy or sell hemp in Iowa until the USDA approves the state plan and the Department publishes notice of the approval in the Iowa Administrative Bulletin. Hemp production will likely not be legalized until the 2020 growing season at the earliest, depending on the timing of the review and approval process. Per Iowa DOA Website
1. The plant Cannabis sativa L. and any part of that plant, including the seeds thereof, and all derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers, whether growing or not, with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis when tested using postdecarboxylation or other similarly reliable methods.
2. A plant of the genus Cannabis other than Cannabis sativa L., with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis when tested using postdecarboxylation or other similarly reliable methods, but only to the extent allowed by the department in accordance with applicable federal law, including the federal hemp law.
“THC” means total tetrahydrocannabinol as determined by an official laboratory test postdecarboxylation.
