Is THCA legal in Iowa? Iowa hemp, CBD, THC limit and kratom laws

The law in Iowa

Iowa splits hemp into two laws. Chapter 204A, the Iowa Hemp Act, covers growing and takes its definitions of hemp and total THC straight from the federal hemp rules in 7 C.F.R. 990.1. Chapter 204 covers what people consume: a consumable hemp product is any hemp product meant to be eaten, absorbed or put on the skin, and it may hold no more than 0.3 percent total THC on a dry weight basis or 4 mg a serving and 10 mg a container, whichever is less.

Those per-serving and per-container caps came from House File 2605, approved on May 17, 2024. A consumable hemp product made and sold under chapter 204 is not a controlled substance, and section 124.204 leaves hemp products out of Schedule I only while their THC, counting isomers, derivatives and analogs, stays at or under 0.3 percent.

1. May 17, 2024The governor approves House File 2605, setting the 4 mg and 10 mg limits, age 21 and HHS registration.
2. July 17, 2024The HHS consumable hemp rules, 641 IAC chapter 156, take effect.
3. March 17, 2026The House passes HF 2133 to make kratom Schedule I; the Senate does not take it up for a final vote.
4. September 30, 2026The Board of Pharmacy proposes adding three synthetic kratom-derived compounds to Schedule I.
5. December 11, 2026The federal limit of 0.4 mg total THC per container begins.

THCA, delta-8 and inhaled hemp

The HHS rules define total THC as 87.7 percent of the THCA plus the delta-9 THC, so THCA counts toward every Iowa limit, and each batch needs a certificate of analysis from an independent accredited laboratory showing its THCA, delta-9 THC and CBD.

Section 204.14A bars possessing, making, selling or using any hemp or hemp product meant to be inhaled, whether smoked, heated or vaped. Raw or dried hemp flower sold in Iowa must carry a printed notice that it is not intended for human consumption by those methods. A violation is a serious misdemeanor.

The same section bars registered makers and sellers from handling synthetic consumable hemp products. The rules define those as products with synthetic or semisynthetic cannabinoids and name delta-8 THC, delta-10 THC, HHC, THC-P and THC-O as examples.

Age, registration and labels

Selling or giving a consumable hemp product to anyone under 21 is a simple misdemeanor under section 204.14D, and under section 204.14E a person under 21 who buys or possesses one faces a civil penalty and community service. The rules require sellers to check a photo ID showing the date of birth.

Every manufacturer and every retailer must register with the Department of Health and Human Services before selling, and the department's registration page says this includes online retailers selling to buyers in Iowa. The fee is $475 a registration type, each registration covers one location for one year, and it must be posted where customers can see it, online before payment. Selling without registering carries a civil penalty of up to $10,000 and is a serious misdemeanor.

Labels must show the lot number, an expiration date, the ingredients, the manufacturer's contact details, the milligrams of each cannabinoid a serving, the total THC a serving and a container, and a warning about drug tests, impairment and children. Sales are barred from vending machines, temporary stands, door to door and private parties.

CBD in food and drinks

A consumable hemp product can be a food, a drink or a dietary supplement, and the rules say a product is not adulterated only because its hemp ingredient is not generally recognized as safe. A liquid product must come in a container of at least 12 fluid ounces. Section 123.49A, added by the 2024 law, bars alcohol license holders from making, importing or wholesaling an alcoholic beverage with THC.

Iowa's medical cannabidiol program under chapter 124E is separate, and chapter 204 says nothing in it authorizes medical cannabidiol.

Kratom, kava, amanita and spores

The 2026 Iowa Code does not list kratom, mitragynine or 7-hydroxymitragynine in any schedule. House File 2133, which would have made kratom Schedule I, passed the House 69 to 26 on March 17, 2026 and was placed on the Senate calendar without a final vote. On September 30, 2026 the Board of Pharmacy published a proposal to add three synthetic kratom-derived compounds, mitragynine pseudoindoxyl, MGM-15 and MGM-16, to Schedule I after federal action; we found no notice that it has been adopted.

We found no Iowa statute naming kava, amanita muscaria or its compounds, or mushroom spores. Psilocybin and psilocyn are Schedule I under section 124.204.
