Is THCP Legal in South Dakota?


Is THCP legal in South Dakota? This is a burning question for many cannabis enthusiasts and those interested in the latest cannabinoid compounds. THCP, or tetrahydrocannabiphorol, has been making waves in the cannabis community due to its potent effects. But before diving into its legality, let's explore what THCP is and why it has garnered so much attention.

Understanding THCP

THCP is a newly discovered cannabinoid found in the cannabis plant. It shares a similar structure to THC, the well-known psychoactive compound responsible for the "high" associated with marijuana. However, THCP is believed to be much more potent than THC, potentially offering stronger effects even at lower doses. This potency has sparked both excitement and concern regarding its use and regulation.

The Legal Landscape in South Dakota

South Dakota's approach to cannabis-related substances has been evolving. Historically, the state had stringent laws against cannabis use, but recent years have seen significant shifts. The legalization of hemp and the introduction of medical cannabis have transformed the landscape. Thanks to the 2018 Farm Bill, hemp and its derivatives, including THCP, were removed from the list of controlled substances, making THCP derived from hemp technically legal in South Dakota. 

However, on March 18, 2024, Governor Kristi Noem signed House Bill 1125 into law, initiating a countdown to the ban on certain hemp-derived THC products in the state. This new legislation, which prohibits the chemical modification or conversion of hemp, will take effect on July 1, 2024. This development marks a significant shift in the state's stance on cannabinoids and their legality. 

The move aligns with broader federal guidelines while addressing local concerns about psychoactive compounds. As regulations tighten, dispensaries, manufacturers, and customers must stay informed to navigate the increasingly complex legal environment. The impact of these changes on the market, sale, possession, consumption, and distribution of cannabis-related products will be significant, requiring continuous adaptation by all stakeholders involved.

Federal vs. State Laws

Cannabis laws in the United States are a complex web of federal and state regulations. Federally, cannabis remains a Schedule I controlled substance, meaning it is considered illegal for all purposes. However, the 2018 Farm Bill legalized hemp and its derivatives, provided they contain less than 0.3% THC. State laws can further complicate this landscape, as states have the autonomy to regulate cannabis and its compounds independently.

THCP: A Closer Look

THCP's chemical structure includes a longer alkyl side chain than THC, which is thought to increase its binding affinity to cannabinoid receptors in the brain. This could explain its heightened psychoactive effects. While research on THCP is still in its infancy, early studies suggest it could have various medical applications, including pain relief and anti-inflammatory properties, as well as potential recreational uses due to its strong psychoactive effects.

Current Status of THCP in South Dakota

As of now, South Dakota does not have specific legislation addressing THCP. South Dakota law enforcement and regulatory bodies typically reference federal guidelines, meaning THCP derived from hemp (with less than 0.3% THC) might be considered legal. However, this interpretation can vary, and it's crucial to stay informed about local regulations. 

The state's stance on cannabis and its derivatives, including CBD and marijuana, significantly influences the market and the legality of such products. THCP falls under the broader cannabinoids category, which has been affected by the farm bill. Current laws around the possession, consumption, cultivation, and distribution of cannabis-related substances are evolving and impacted by both state and federal oversight. 

The effects of THCP and other compounds are subjects of ongoing research, with a focus on medical and recreational use. As health officials and customers await more definitive guidelines, entities like dispensaries and manufacturers must navigate a complex legal landscape. High-profile figures such as Gov. Kristi Noem play a significant role in shaping these policies, affecting the sale and use of cannabis plant products across the state.

THCP vs. Other Cannabinoids

While THCP is chemically similar to THC, it's distinct in its potency. CBD, another well-known cannabinoid, is non-psychoactive and widely legal under federal law. In South Dakota, CBD products derived from hemp are legal, provided they meet federal THC limits. The legality of other cannabinoids like Delta-8 THC and THCV varies, making the legal landscape for THCP even more uncertain.

Possession and Consumption

In South Dakota, possessing and consuming cannabis products that exceed the federal THC limit is illegal. If THCP products contain more than 0.3% THC, they would likely fall under this prohibition. Penalties for possession can include fines and jail time, depending on the quantity and context of the possession.

Cultivation and Distribution

Cultivating and distributing THCP in South Dakota would require navigating both state and federal regulations. Currently, businesses can grow and sell hemp-derived products, but these must comply with stringent testing and licensing requirements. The lack of specific THCP regulations means that businesses should proceed with caution and seek legal advice.

Medical Use of THCP

The medical potential of THCP is promising but under-researched. Anecdotal reports suggest it could offer significant pain relief and other therapeutic benefits. However, without robust clinical trials and regulatory approval, its use in medical contexts remains limited and legally ambiguous in South Dakota.

Recreational Use of THCP

Recreational cannabis use is still illegal in South Dakota. This includes any products that contain psychoactive compounds like THC and THCP unless derived from hemp and compliant with federal THC limits. Despite the legal restrictions, the popularity of THCP in the recreational market highlights a growing demand for potent cannabinoid products.

The Future of THCP in South Dakota

The legal status of THCP in South Dakota is likely to evolve as more is understood about this cannabinoid. Advocacy groups and changing public opinion could influence future legislation. Staying informed about ongoing legislative efforts and participating in public discourse can help shape the future of THCP in the state.

Comparison with Other States

Neighboring states like Colorado and Montana have more progressive cannabis laws, potentially influencing South Dakota's approach. The legal status of THC-P in these states varies, with some allowing broader use of hemp-derived cannabinoids. Understanding regional trends can provide insight into potential changes in South Dakota.

Consumer Information

For those interested in purchasing THCP legally, it's essential to source products from reputable vendors who comply with state and federal regulations. Look for third-party lab testing and clear labeling to ensure product safety and legality.


What is THCP? 

THCP, or tetrahydrocannabiphorol, is a potent cannabinoid found in the cannabis plant, similar in structure to THC but potentially much stronger.

How does THCP differ from THC? 

THCP has a longer alkyl side chain than THC, which may increase its binding affinity to cannabinoid receptors, resulting in stronger effects.

Is THCP safe for medical use? 

While early research suggests potential medical benefits, there is insufficient clinical evidence to confirm its safety and efficacy. Always consult with a healthcare professional before using new cannabinoids for medical purposes.

Will THCP show up on a drug test?

THCP is a cannabinoid that may appear on a drug test. Due to its structural similarities with THC, standard tests designed to detect THC and its metabolites might also identify THCP. However, detection can depend on the test's specificity and sensitivity and the amount and frequency of THCP consumption.


The evolving legal landscape surrounding cannabis and its derivatives, including THCP, requires constant attention and adaptation by all stakeholders involved. While the federal legalization of hemp has opened up new opportunities for businesses and consumers, state laws and regulations must also be carefully considered. As research continues on cannabinoids like THCP, it is essential to stay informed about changes in legislation and potential medical uses. 

In South Dakota, THCP and other cannabinoids are considered legal as long as they are derived from hemp, contain less than 0.3% THC, and meet federal and state guidelines. As the market for cannabis-related products continues to grow, all involved parties need to stay informed and compliant with both federal and state laws.
