DES MOINES, Iowa (AP) — Iowa legislators must create rules to regulate hemp production in the state now that Congress has legalized the crop and farmers are eager to start planting.

Hemp comes from the same plant as marijuana but doesn’t contain THC, the compound that causes a high. Hemp is used in clothing, textiles, building materials, paper and food.

Congress approved hemp production in the 2018 farm bill. The Iowa attorney general and state agriculture officials will meet this month to discuss state regulations for hemp.

One issue lawmakers may consider is if hemp should be allowed to make cannabidiol. Advocates say CBD can treat anxiety, epilepsy and depression.

While hemp-derived CBD is allowed federally, Iowa’s medical marijuana law doesn’t allow CBD to be processed from industrial hemp.
