Is THCa Legal in Arkansas? Guide to Buying and Possession Rules
Key Takeaways:
- Legal Definition: Arkansas law (Act 629 of 2023) bans most hemp products that can convert to Delta-9 THC, including THCa, even if under 0.3 percent Delta-9 by weight.
- Buying Tip: Only buy from licensed Arkansas hemp retailers that show total THC and THCa levels on a current COA.
- Compliance Risk: THCa itself is non-psychoactive, but Arkansas treats products that mimic or convert to Delta-9 THC as illegal.
THCa has drawn attention from consumers and regulators alike. In its raw form, it is non-intoxicating, but when heated, it converts into Delta-9 THC, the psychoactive compound in cannabis. This chemical shift has made THCa a focus of enforcement in Arkansas, where recent legislation bans hemp products that can convert into Delta-9 THC, including most THCa-rich items.
At Earthy Select, we provide hemp-derived products that meet all current state and federal rules. Each batch is lab tested, clearly labeled, and shipped with full documentation for compliance and transparency.
In this article, we’ll break down whether THCa is legal in Arkansas, in addition to restrictions, which products remain permitted, and what consumers should know before buying or possessing hemp-derived cannabinoids in the state.
What is THCa and Why Does It Matter in Arkansas?
THCa, or tetrahydrocannabinolic acid, is a naturally occurring compound in raw hemp and cannabis. It is non-intoxicating until heated, when it converts into Delta-9 THC through a process called decarboxylation.
In Arkansas, this conversion is what makes THCa legally sensitive. Under Act 629, regulators treat hemp products that can convert into Delta-9 THC as controlled substances, even if they test below 0.3 percent Delta-9 THC before activation. Compliance depends on total THC potential rather than raw THCa content alone.
For consumers and retailers, understanding that distinction is critical. A product that seems compliant on paper can become illegal once heated, mislabeled, or sold outside licensed hemp channels.
Is THCa Legal in Arkansas?
No. Under Act 629 (2023), Arkansas prohibits many hemp-derived intoxicating substances – including THCa when used or marketed as a psychoactive product.
Arkansas courts have ruled that the prohibition is valid and state law may be more stringent than federal rules.
If you are considering a THCa product in Arkansas, you must confirm the product is explicitly allowed under Arkansas law – not just meeting the federal hemp threshold of 0.3 % Delta-9 THC – because compliance under state law depends on product form, marketing, intended use, and whether it converts into Delta-9 THC.
Federal Law vs. State Law: The THCa Grey Area
The 2018 Farm Bill legalized hemp and its derivatives federally if they contain no more than 0.3 percent Delta-9 THC by dry weight. However, the DEA now interprets compliance using total THC, which includes the potential conversion of THCa into Delta-9 THC.
Arkansas law goes further. Under Act 629 (2023), the state bans hemp products that can convert into or mimic Delta-9 THC, effectively closing the federal grey area for THCa. Products rich in THCa are treated as controlled substances regardless of pre-heating lab results.
Because Arkansas enforces total-THC standards, labeling and Certificates of Analysis showing only Delta-9 values are no longer enough to ensure compliance. Consumers should verify that any hemp product sold in-state is licensed under Arkansas’s hemp program and clearly meets the total-THC requirement.
Understanding Arkansas THCa Regulations
Arkansas regulates hemp under Act 629 (2023), which prohibits hemp-derived products that can convert into or mimic Delta-9 THC. While the law does not list THCa by name, it includes all cannabinoids with intoxicating potential within its definition of controlled hemp derivatives. This means THCa-rich flower and concentrates are treated as illegal if they exceed total-THC limits or are marketed for psychoactive use.
Unlike the state’s medical marijuana program, which allows only registered patients to access Delta-9 THC products, general consumers cannot legally buy or possess THCa items that fall under the ban. Compliance now depends on total-THC calculations, proper licensing, and approved distribution channels.
For broader context on how other states define and enforce hemp-derived cannabinoid laws, see our state-level THCa guide.
Products that look or smell like high-THC cannabis without clear labeling or valid Certificates of Analysis risk being seized as marijuana, so verified sourcing is critical.
Legal THCa Products in AR: What Can You Actually Buy?
Arkansas residents cannot legally buy or possess most THCa products under Act 629 (2023). The law bans hemp-derived items that can convert into or mimic Delta-9 THC, including THCa flower, pre-rolls, and concentrates. These products are treated as controlled substances, even if they contain less than 0.3 percent Delta-9 THC before heating.
The only hemp products currently permitted in Arkansas are non-intoxicating formulations that stay within total-THC compliance, such as CBD oils or topicals made from approved hemp sources. Every legal product must have a Certificate of Analysis showing total THC below 0.3 percent and meet the state’s labeling and licensing requirements.
Retailers cannot legally sell THCa-rich items in Arkansas, and possession of such products may lead to enforcement. For consumers comparing legality across states, see our state-level THCa guide for a full overview of where THCa products remain available
Buying THCa in Arkansas: What to Know
Buying THCa products in Arkansas is no longer legal under Act 629 (2023), which bans hemp-derived cannabinoids that can convert into or mimic Delta-9 THC. This includes THCa-rich flower, pre-rolls, and concentrates, regardless of their Delta-9 THC levels before heating.
Consumers should avoid purchasing THCa products in-state or online for shipment into Arkansas. Only non-intoxicating hemp items, such as CBD products that meet total-THC limits below 0.3 percent, remain lawful.
You must still be 21 or older to purchase hemp products, but online sellers offering THCa for Arkansas delivery are operating outside state law. Enforcement has increased, and mislabeled products risk seizure or citation.
To stay compliant, buy only clearly labeled, lab-tested CBD or other non-intoxicating hemp formulations, and always keep the Certificate of Analysis as proof of legality. For a broader comparison of hemp regulations, visit our state-level THCa guide.
Be aware that laws are continually evolving. If you’re comparing THCa with other cannabinoids, it’s helpful to read about Delta-8 legality in Arkansas, since enforcement trends often overlap.
Can You Travel With THCa in Arkansas?
No. Traveling with THCa products in Arkansas is not legal under Act 629 (2023). The state classifies hemp-derived cannabinoids that can convert into or mimic Delta-9 THC as controlled substances, which includes THCa flower, pre-rolls, and concentrates.
If you are transporting hemp-derived products such as CBD oils or other non-intoxicating items that meet total-THC limits of 0.3 percent or less, keep them sealed in their original packaging with a Certificate of Analysis available to verify compliance.
Consuming or carrying THCa products in public, while driving, or at airports may result in enforcement since law enforcement cannot easily distinguish THCa from marijuana. Flying with any high-THCa hemp product is strongly discouraged and may violate both TSA and state restrictions.

Tips for Staying Compliant as a Resident
Arkansas law under Act 629 (2023) bans most hemp-derived products that can convert into Delta-9 THC, including THCa-rich flower, pre-rolls, and concentrates. Residents can still use non-intoxicating hemp products, such as CBD oils or topicals, as long as they meet total-THC requirements and are sold by licensed retailers. These tips can help you stay compliant and avoid enforcement issues.
Check Lab Results
Before purchasing any hemp-derived product, review the Certificate of Analysis to confirm total THC at or below 0.3 percent. Legitimate CBD brands provide current, batch-specific lab reports that clearly show compliance.
Keep Original Packaging
Keep products in their original labeled containers, which display cannabinoid content, hemp source, and compliance details. Unmarked or repackaged items can be mistaken for illegal marijuana.
Store Responsibly
Store hemp products in a sealed container at home or in another private location. Avoid transporting or using any THC-containing products in public or while driving.
Stay Informed
Arkansas enforcement continues to evolve. Follow updates from the Arkansas Department of Agriculture and reputable hemp retailers, and review our state-level THCa guide for information on where THCa products remain legal in other states.
Your THCa Guide for Residents in AR
If you live in Arkansas and are interested in hemp-derived products, the most important thing is to stay informed. Act 629 (2023) bans THCa-rich products that can convert into Delta-9 THC, meaning there is no longer a legal window for THCa use in the state.
Stick to non-intoxicating hemp products such as CBD formulations that meet total-THC limits and come with verified Certificates of Analysis. Always keep products in their original packaging, avoid public use, and confirm that lab reports list total THC at or below 0.3 percent. These steps ensure your hemp purchases remain lawful under Arkansas regulations.
