(Radio Iowa) - New state rules regulating hemp products have gone into effect this week.
According to the Iowa Hemp Alliance, up to 80 percent of the products at the businesses who've joined the group are prohibited under the new regulations. In mid-May Governor Reynolds signed the law to limit the amount of T-H-C -- the ingredient that causes the high -- that can be in consumable hemp products sold in Iowa.
Hemp retailers say the Iowa Department of Health and Human Services rules have a per serving T-H-C limit that isn't in the law and they've sued. Climbing Kites -- a popular hemp-infused sparkling water -- had been brewed in Iowa, but operations have been moved to Illinois and Ohio.
