Oklahoma’s hemp cultivation and production laws currently follow federal regulations and maintain that natural cannabinoids derived from hemp plants are legal for Oklahoma residents.

According to Oklahoma statutes, delta 8 THC, CBD, and various other cannabinoids and hemp compounds remain legal within state lines as long as they’re made from hemp (not marijuana).

In this article, we will discuss the up to date legal status of these hemp derivatives and THC isomers, but do note that this doesn’t constitute legal advice though. We will also explain the differences between delta 8 THC and other cannabinoids and why some people refer to delta 8 THC as one of the artificially derived cannabinoids. At the same time, most experts maintain that it’s a natural compound.

We’ll also discuss the legality of hemp and marijuana (both of which are types of Cannabis sativa plants) as well as other hemp-derived compounds in Oklahoma, how to use delta 8 safely, and where to buy it locally.

Is Delta 8 Legal in Oklahoma?

Delta 8 THC is entirely legal in Oklahoma. There is just one restriction that prevents users under the age of 21 from purchasing delta 8 products.

Oklahoma’s Industrial Hemp Program declares that hemp and all cannabinoids derived from it are legal. The program defines the hemp plant (Cannabis Sativa L.) as a cannabis plant containing no more than 0.3% THC by dry weight basis. Cannabis plants containing more than 0.3% THC are considered marijuana plants and are illegal and considered controlled substances in the state.

Oklahoma’s laws mimic the federal 2018 Farm Bill, which also legalizes cannabinoids derived from hemp and the sale and use of hemp flowers [1].

While this federal law boosted hemp retail sales nationwide, it also created a loophole and technically made psychoactive cannabinoids like delta 8 and delta 10 legal and readily available to anyone, as long as the THC content doesn’t exceed 0.3%.

As such, you’d easily find intoxicating hemp products in hemp stores and local stores, such as headshops, vape stores, smoke shops, and CBD stores. You can even buy hemp-derived cannabis products in gas stations and convenience stores.

Although many states aligned their laws with those of the federal government, some either placed stricter regulations on psychoactive hemp products through senate bills, house bills, and executive orders or fully banned and classified them as illegal under the state’s Controlled Substances Act. Take, for example, the Oregon Liquor and Cannabis Commission, which prohibited synthetically derived delta 8 THC, the delta 8 form we commonly see in the market.

Several attempts have also been made to ban delta 8 products in Oklahoma, but none have been successful so far. In 2025, Governor Kevin Stitt released a letter that urged enforcers to create a task force that would crack down on illegal delta 8 production, distribution, and sales due to growing public health and safety risks. The letter explicitly mentioned delta 8, delta 10, HHC, THCO, THCP, and THCV.

Is Delta 10 THC Legal in Oklahoma?

Delta 10 THC is another non-psychoactive cannabinoid extracted from what Oklahoma considers “industrial hemp.” As such, it’s legal to purchase and consume within state lines, provided you are over the age of 21.

Marijuana Laws in Oklahoma

Although hemp and hemp-derived compounds are wholly legal in Oklahoma, the state laws governing marijuana are more strict.

Marijuana products are defined as any cannabis extracts that contain delta 9 THC concentrations greater than 0.3% by dry weight. Recreational marijuana has yet to be legalized in Oklahoma.

However, medical marijuana is legal throughout the state, so you can purchase marijuana and delta 9 THC (commonly referred to as “THC”) products, provided you have a medical marijuana card.

Do I Need A Medical Card in Oklahoma To Order Delta 8 THC?

You do not need a medical marijuana (MMJ) card to purchase delta 8 THC in the state of Oklahoma. Since hemp and all of its constituents are legalized in Oklahoma, you can buy and use delta 8 THC legally in any part of the state as long as you are over 21 years of age.

Delta 8 THC is a naturally occurring cannabinoid found in hemp plants. It’s similar to CBD and follows all of the same rules and regulations. 

However, because delta 8 is only found in trace amounts, we convert hemp-sourced CBD into delta 8 through a chemical process to get a higher yield. Because of this process, some people then see delta 8 and other cannabinoids converted from CBD as synthetic cannabinoids and should be considered illegal, despite these cannabinoids naturally occurring in nature.

Oklahoma legalized marijuana for medical use, and medical marijuana patients registered in the state’s robust medical marijuana program have access to licensed dispensaries and legal marijuana. If you want to use cannabis for medical purposes, such as for chronic pain or multiple sclerosis, be sure to check out the state’s medical cannabis board’s website for the requirements to register.

What’s The Difference Between Delta 8 THC & Delta 9 THC?

Delta 8 THC and delta 9 THC are very similar in their chemical structure. The only difference between them on a molecular level is where the double bond occurs in the carbon chain. As their names suggest, the double bond is found on the eighth carbon bond in delta 8 THC and on the ninth carbon bond in delta 9 THC.

While these compounds differ only slightly in their molecular construction, they have different effects on the human body. Delta 9 THC is typically referred to simply as THC, and it is the psychoactive compound in marijuana that produces a high. It can lead to feelings of euphoria, creativity, and relaxation.

Delta 8 THC is far less potent, but many users maintain that it can still provide milder psychoactive effects. Most people note that delta 8 THC is about half as potent as delta 9 THC, is less likely to produce feelings of anxiousness or paranoia, and delivers a more relaxing and mellow experience.

Finally, these two compounds differ in their legality. Delta 9 THC is still illegal for recreational use in most states, while delta 8 THC is legal in nearly every state, even those where marijuana isn’t.

Do note though that delta 8, like delta 9, can also trigger positive drug tests. If you have an upcoming drug test for work or other purposes, you should refrain from consuming delta 8 products for a while.

Is Delta 8 THC Natural?

The word “natural” can mean different things depending on the context in which it’s used. When consumers read that a product is all-natural, they often believe it is found in nature exactly as they buy it.

When the FDA and other regulatory agencies state that something is natural, it doesn’t contain anything synthetic. When it comes to regulated substances like delta 8 THC, “natural” means the components come from nature and aren’t manufactured, but they could be prepared or extracted in a lab.

Delta 8 THC occurs naturally in hemp plants, so in the eyes of the FDA, it is “natural.” The cannabinoid is extracted from the plant and suspended in other constituents in a controlled lab setting. It doesn’t contain anything synthetic, so it’s considered natural.

How to Use Delta 8 THC

Much like delta 9 THC and other cannabinoids, there are many ways to use delta 8 THC, depending on your preference. Each form of consumption has its pros and cons, which will be discussed below.

1. Delta 8 THC Tinctures

A tincture is a liquid, usually containing vegetable glycerin or some fatty oil. The liquid is used to suspend delta 8 THC extract, either pulled from a distillate or directly from a hemp plant. Users hold the tincture under their tongue for about 30 seconds before swallowing. This allows the delta 8 THC to be absorbed by the capillaries lining your mouth.

Tinctures offer a discreet way to consume delta 8 THC. They come in a dropper bottle that is easy to transport. They also provide a consumption method that doesn’t involve inhaling, so it’s ideal for those who cannot or prefer not to use vapes.

However, tinctures can take an hour or two to deliver the desired effects, and some individuals complain about the taste.

2. Delta 8 THC Vapes

Many delta 8 manufacturers offer vape cartridges or disposable vapes containing delta 8 THC. Vapes have a concentrated form of delta 8 THC that you can inhale like a typical nicotine vape.

Vapes deliver the desired effects in just a few minutes, requiring the least amount of planning for consumption. They’re very easy to transport, and they’re the easiest to dose due to the rapid onset effects.

Vapes require that you inhale the substance, so they may not be ideal for individuals who have asthma or other medical issues that make smoking and vaping impractical.

3. Delta 8 THC Gummies

Delta 8 THC gummies are chewable gummy candies that contain delta 8 THC. They’re typically flavored to make them enjoyable.

Gummies are great for individuals who choose not to vape, and they offer a very natural and familiar way to consume delta 8. They also help those who don’t like tinctures to avoid the sometimes unpleasant taste.

Gummies take the longest to deliver the desired effects because the delta 8 THC will need to be processed by your digestive tract. They can take up to three hours to become effective, so planning and dosing can be a challenge in some cases.

What’s The Future of Delta 8 THC in Oklahoma?

Delta 8 THC is currently legal in Oklahoma and all other naturally occurring cannabinoids in hemp plants. There are just two restrictions in place: the first requires purchasers to be over 21 years of age, and the second requires that any product containing hemp-derived cannabinoids contain less than 0.3% delta 9 THC by dry weight.

There are currently no proposed laws in Oklahoma that would restrict the sale of delta 8 products or illegalize them altogether. Most states are legalizing delta 8 THC, and since legalization is in line with federal law, delta 8 will likely remain legal in Oklahoma, at least for the foreseeable future.
