Is Delta 8 THC Legal in Iowa? 

Hemp-derived delta 8 THC is not legal in Iowa. Iowa doesn’t explicitly ban delta 8, but state law is not in favor of products containing this cannabinoid. 

Delta 8 THC is an illegal substance in Iowa. The state doesn’t make an exception for hemp-derived tetrahydrocannabinols in their Controlled Substances Act. 

The state lists all tetrahydrocannabinols, their synthetic equivalents, derivatives, and isomers with similar chemical structure and pharmacological activity as illegal. 

Under the Iowa Hemp Act, hemp products can contain a THC concentration of 0.3% without specifying delta 9 THC. This means that hemp products are only lawful if the total THC concentration in them doesn’t exceed 0.3%, which includes delta 8 THC.

Iowa was one of the last states to legalize the hemp plant and its cannabinoids. The Hawkeye State allows the sale and possession of hemp-derived CBD products with less than 0.3% THC to the extent of federal law. 

That said, not all CBD products are legal in the state. Iowa strictly prohibits the sale of smokable hemp products, so you can’t order these products legally.

What is Delta 8 THC? 

As an isomer of delta 9 THC or the primary intoxicating cannabinoid of cannabis delta 8 THC displays mildly intoxicating effects. 

Not only is it twice less intoxicating than delta 9 THC, but it also doesn’t cause the same euphoric “high.” As reported by users, delta 8 THC’s “high” is more subtle and without the intense anxiety and paranoia caused by high-THC strains. 

Delta 8 THC and Federal Law 

The legality of delta 8 THC on a federal level is hazy. States have been cracking down on the loophole that makes buying and selling hemp products infused with D8 legal. The main reason for it is that D8 is an intoxicating cannabinoid that’s manufactured from hemp-derived cannabidiol (CBD). 

Delta 8 THC exists in the hemp plant in its natural state only in trace amounts. Therefore, its organic extraction is extremely challenging. As a solution to this problem, manufacturers have started using hemp-derived cannabidiol (CBD) and chemically convert it into delta 8 THC. You’ve probably heard that most hemp products on the market that are infused with D8 THC are made from chemically altered hemp-CBD. 

This process of converting one chemical compound into another is known as isomerization. Isomerization is a chemical process in which one molecule, like cannabidiol, is transformed into any of its isomeric forms — in this case, D8 THC. Isomers are chemical compounds that have the same chemical composition but different structure and physical and chemical properties. 

Such conversion of hemp-CBD into D8 is the root of the legal confusion because there’s a risk that the Drug Enforcement Administration (DEA) will consider this isomer a synthetically derived tetrahydrocannabinol. 

In 2020, the DEA issued a report on hemp (Interim Rule) that stated: “all synthetically derived tetrahydrocannabinols remain Schedule I controlled substances.”

The report also specified that if a compound is considered synthetic, the 2018 Farm Bill doesn’t have any power over its legality. 

Recently, the DEA also seems to have “secretly” added D8 THC on its Orange Book of controlled substances. While many argue that this is the end of D8 THC, others await a formal statement for its prohibition. 

Final Thoughts

Delta 8 THC is not legal to buy in Iowa. The Hawkeye State listed hemp-derived tetrahydrocannabinols in their Controlled Substances Act. Residents of Iowa should avoid ordering hemp-derived D8 online until the law loosens up.
