Now, let’s address the burning question: Is THCA flower legal? The answer is a resounding yes! If you’re curious about the legal status of THCA flowers, you’re not alone. With the increasing popularity of cannabis and its derivatives, it’s essential to stay informed about the legalities surrounding different products.


Understanding THCA Flower?

THCA flower, grown by VIIA Hemp Co and similar companies, is an innovative product derived from hemp plants. THCA stands for tetrahydrocannabinol acid, the non-psychoactive precursor to THC (tetrahydrocannabinol). While THC is known for its psychoactive properties, THCA does not induce the same effects when consumed. It’s important to note that THCA flower contains only trace amounts of THC, containing less than 0.3% delta-9 THC by dried weight.

The Legal Status of THCA

Analyzing the federal legality of THCA involves a comprehensive examination of cannabis laws from the 1970s to the present. During this period, various legal developments and communications have shaped the legal landscape surrounding THCA. Let’s delve into these critical milestones chronologically:

  • The Controlled Substances Act: Back in 1970, the Controlled Substances Act (CSA) classified marijuana as a Schedule I drug, imposing severe penalties for its cultivation and use. The CSA thus ruled “tetrahydrocannabinol” as a prohibited substance.
  • The 2018 Farm Bill: The enactment of the 2018 Farm Bill marked a significant milestone. One of its key components was incorporating the proposed Hemp Farming Act of 2018, which aimed to reclassify hemp, defined as cannabis with less than 0.3% THC, as an ordinary agricultural commodity rather than a Schedule I controlled substance. This act was incorporated into the 2018 United States farm bill, and became law on December 20, 2018. By differentiating industrial hemp from marijuana at the federal level based solely on delta-9 tetrahydrocannabinol (THC) content, the legislation clarified the criteria for Schedule I substance classification.
  • The DEA’s 2020 IFR: The Drug Enforcement Administration (DEA) issued an interim final rule (IFR) in 2020, responding to inquiries about the legality of hemp-derived substances. The IFR clarified that a Cannabis sativa derivative would meet the definition of hemp under the 2018 Farm Bill if it contained less than 0.3% delta-9 THC at the time of sale. Thus, THCA products falling within this threshold could be considered hemp rather than marijuana, according to the DEA’s communication.
  • The Alabama Board of Pharmacy Letter: In 2021, the Alabama Board of Pharmacy sought further clarification from the DEA due to the rise of hemp products in the state. The DEA’s response affirmed that cannabinoids extracted from hemp, containing less than 0.3% THC, met the federal definition of hemp.
  • The DEA Cannabis Seed Letter: In January 2022, the DEA issued a detailed opinion on the legality of cannabis seeds. The letter reiterated that substances “extracted from the cannabis plant” with a delta-9-tetrahydrocannabinol concentration of no more than 0.3% on a dry weight basis qualified as hemp and were not controlled under the CSA. Although the focus was on cannabis seeds, this principle extends to THCA.
  • The Ninth Circuit Opinion: In 2022, the Ninth Circuit Court of Appeals provided a perspective on the distinction between marijuana and hemp in a delta 8 THC trademark dispute. It noted that historically, the differentiating factor had been the percentage of delta-9 THC. Consequently, as long as the THC concentration in a THCA product remains below 0.3%, it should be classified as hemp.

THCA States Legality

Specific measures have yet to be taken by states to prohibit THCA. However, it is essential to review your state’s hemp and cannabis laws, as the exact wording may vary. Generally, states tend to align with federal government policies, and any deviations typically favor THCA, as in the ninth circuit.

Lab Testing and Compliance

Lab testing is the only way to prove that your hemp flower is high in THCA and contains less than 0.3% THC. THCA Flower grown by VIIA Hemp Co and other quality-assured companies undergo rigorous lab testing and compliance standards. These tests verify that the product contains less than 0.3% THC, thus confirming its classification as hemp rather than marijuana.


THCA flower is legal in many areas, thanks to the 2018 Farm Bill that introduced the legalization of hemp-derived products. Explore the benefits of THCA flowers with confidence!
