As new cannabinoids like THCp (tetrahydrocannabiphorol) gain popularity, consumers and businesses alike are asking the same question: Is THCp legal? The answer depends on how the product is derived, how much Delta-9 THC it contains, and which state you’re in.
Let’s explore the science and legal framework behind THCp to better understand where it fits into the evolving landscape of hemp and THC laws in the United States.
What Is THCp?
THCp is a naturally occurring cannabinoid first identified in 2019 by Italian researchers. It shares a similar structure to Delta-9 THC—the primary psychoactive compound in cannabis—but features a seven-carbon alkyl chain, allowing it to bind more strongly to the body’s CB1 receptors. This increased binding affinity makes THCp significantly more potent, even at smaller doses.
THCp can be derived from hemp, which is legally defined under the 2018 U.S. Farm Bill as cannabis containing less than 0.3% Delta-9 THC on a dry-weight basis. This detail is key to understanding THCp’s legal status.
The 2018 Farm Bill and Federal Legality
At the federal level, THCp is considered legal when derived from hemp and when the finished product contains less than 0.3% Delta-9 THC. The 2018 Farm Bill effectively legalized hemp and all of its naturally occurring compounds, including cannabinoids like CBD, Delta-8, and THCp—so long as they meet that threshold.
However, while federal law permits hemp-derived THCp, it does not explicitly regulate or approve its use. This gray area has led to differing interpretations across states.
State Laws and Regulatory Variations
Each state has the authority to regulate cannabinoids independently. Some states have adopted stricter hemp laws, banning psychoactive cannabinoids like Delta-8, Delta-10, and THCp regardless of their hemp origin.
Others follow the federal definition, allowing hemp-derived products as long as they stay under the 0.3% Delta-9 THC limit.
Before purchasing or selling THCp products, it’s important to check your state’s specific hemp regulations to ensure compliance.
The Importance of Lab Testing and Transparency
Given the evolving regulatory environment, consumers should only purchase THCp products that are third-party lab tested for purity, potency, and compliance. Verified lab results confirm that products meet the legal THC limit and are free from contaminants—a crucial factor for both safety and legality.
The Future of THC Laws
As cannabinoid science advances, lawmakers are continuing to refine hemp regulations. It’s likely that future legislation will provide more clarity on synthetic cannabinoids, potency limits, and labeling standards for products like THCp.
Until then, hemp-derived THCp remains federally legal in most states, but consumers should stay informed and cautious as the legal landscape continues to evolve.
Key Takeaway
THCp occupies a legally complex but federally permissible position under current hemp laws. Its legality ultimately depends on how it’s derived and where it’s sold or used.
