Residents of the Palmetto State want to know: Is THCa legal in South Carolina? Like all states dealing with cannabis products, South Carolina makes its own laws that differ from other state laws and federal laws. South Carolina has strict cannabis laws in place. It is one of the few states that has not legalized or decriminalized recreational or medical marijuana plants. However, it has come around to legalize low-THC hemp products.
So, where does THCa stand in all of this? Cannabis laws can get confusing. But it’s important to understand all aspects of legal hemp in South Carolina to ensure you don’t get in trouble when using it in the state. This article covers all South Carolina state and federal regulations on THCa. By the end, you’ll have a clear and confident understanding of the laws in the Palmetto State.
Understanding THCa
THCa is the non-euphoric precursor to THC, the primary psychoactive component of marijuana. This naturally occurring cannabinoid found in the cannabis plant contains a carboxyl group that blocks its ability to interact with the CB1 receptor of your endocannabinoid system or ECS. CB1 receptors, which are primarily located in your brain and central nervous system (CNS), are responsible for producing euphoric effects when interacting with certain cannabinoids. Therefore, it does not have any mind-altering abilities in its raw state.
THCa also interacts with the CB2 receptors of your peripheral nervous system (PNS) to provide wellness benefits. It can help to relieve physical discomfort and environmental stress on the body. THCa may also provide cognitive support.
When heated, THCa loses its carboxyl group and transforms into THC (Delta 9 THC, Delta 9, D9 THC, or D9). Without the carboxyl group, THC can bind tightly with the CB1 receptors in your brain to provide euphoric effects.
THCa’s dual nature leads to confusion in the legal landscape. The Farm Bill of 2018 established federal guidelines for products containing hemp-derived cannabinoids with a total THC content of 0.3% or less to have legal status under federal law. Many states follow these guidelines, allowing hemp-derived THCa products for consumer consumption.
However, THCa does have the potential to transform into high-content THC, which could potentially go beyond the legal limits. This puts THCa in a potential gray area in many states. So, what’s the legal status of hemp-derived THCa in South Carolina?
Legal Status of THCa in South Carolina
Good news: as of this writing, THCa is legal in South Carolina as long as products containing the cannabinoid are hemp-derived and do not exceed the federally legal THC limit of 0.3% at the point of sale. When it comes to cannabis, South Carolina law has many nuances. And like all cannabis laws, it’s always evolving. For the large part, South Carolina aligns with the federal Farm Bill.
The Farm Bill went into effect in 2018. It legalized hemp and products containing hemp-derived cannabinoids with a THC content of 0.3% or less. Many states align with the Farm Bill. However, some states have strict cannabis laws in place. Other states are lax and allow cannabis regardless of its origin or THC concentration.
South Carolina is also stricter on cannabis than other states because it does not legalize or decriminalize medical marijuana and offers no medical cannabis programs. Recreational cannabis is permitted, but only if it is non-euphoric, hemp-derived, and has a THC concentration of less than 0.3%. This paves the way for consumers to enjoy the benefits of THCa hemp flower.
However, the law does not explicitly address THCa, leaving it in a potential gray area. As a non-psychoactive precursor to THC, THCa itself is not intoxicating, but when heated, it converts into psychoactive THC. Like other states—such as Georgia, New York, and Pennsylvania—grappling with THCa regulations, South Carolina may introduce future amendments that could alter its legal status. For now, however, Palmetto State residents shouldn’t be worried about consuming legal, hemp-derived THCa products in the state.
Regulations and Restrictions
THCa’s ability to transform into Delta 9 THC presents a potential legal loophole. In the past, hemp-derived THCa was sold legally because it had a low THC content at the point of sale. This satisfied federal law and many state laws. However, people recognized its ability to convert into THC after decarboxylation (heating) and provide euphoric effects.
Many states began addressing the issue by ensuring the THCa sold and cultivated in their communities was low THC. However, challenges arise. For one, many states failed to specifically mention THCa in their cannabis laws, leaving it in a gray area. Furthermore, the preharvest testing could not detect THC content after decarboxylation occurred.
Fortunately, many reputable companies provide a solution by conducting lab testing. They send products to a third-party lab for testing, ensuring they meet compliance regulations. This process also ensures the product’s potency and purity.
To sum it up, if you want to purchase legal cannabis that offers optimal purity and potency, choose a reputable provider of THCa products.
Hemp-Derived Products and the Farm Bill
The Farm Bill’s passage recognized the benefits of industrial hemp. Once adopted, it made it easier to incorporate hemp into everyday products. It increased accessibility for people who used hemp products for recreational and medical purposes. More people understood how hemp could support their well-being, and the cannabis market began growing in leaps and bounds.
However, despite growing cannabis adoption, there is still confusion surrounding THCa. In 2024, U.S. House lawmakers sought to clear up some of the confusion under federal law by adopting an amendment that would close the THCa legal loophole. Based on the DEA’s interpretation, THCa is federally illegal if the total THC content (including potential conversion to Delta 9 THC after decarboxylation) exceeds 0.3% on a dry weight basis.
While the 2018 Farm Bill legalized hemp and its derivatives containing no more than 0.3% Delta 9 THC, the DEA clarified in 2024 that total THC calculations should take into account THCa, effectively closing the perceived “loophole” that some in the hemp industry relied upon. This means that high-THCa hemp flower, which can convert to psychoactive THC when heated, may be a controlled substance under federal law.
However, enforcement and interpretation can vary at the state level, so legality often depends on local regulations. Current law states that all cannabis products must be tested preharvest to ensure they contain a THC content of 0.3% or below.
However, this is not enforced for post-harvest products that have undergone decarboxylation. Therefore, according to the DEA, all cannabis laws that are currently enforced cover THCa. The only way that would change is if lawmakers introduced a law to test cannabis post-harvest. However, such a stipulation would be much more complicated to enforce.
Legal Implications of Selling and Possessing in South Carolina
Under South Carolina law, cannabis only has legal status if it is hemp-derived and has a THC content of 0.3% THC or less. So what happens if you sell or possess cannabis over the legal limit? Here are some THCa South Carolina laws to consider. These laws apply to marijuana, not hemp.
- Possession. Having up to one ounce (28 g) of marijuana is considered a misdemeanor. Possession is punishable by a $200 fine and up to 30 days in jail.
- Possession with Intent to Distribute. Individuals with more than one ounce of marijuana may be charged with possession with the intent to distribute. This crime is punishable by 5-10 years in prison and hefty fines.
- Cultivation. While hemp cultivation is legal under federal law (if it contains 0.3% THC or less), South Carolina law does not differentiate between hemp and marijuana when it comes to cultivation penalties. Someone found cultivating less than 100 plants of THCa flower in South Carolina can face five years in prison. This sentence increases to 25 years if they cultivate more than 100 THCa flower South Carolina plants.
Impact on Access to THCa
The strict cannabis laws in South Carolina may cause some vendors to take THCa off their shelves, and some consumers may not want to buy it. The potential gray areas make it difficult to navigate laws—and no one wants to get in trouble. If consumers are found with illegal cannabis, they could get arrested. Businesses could face fines and penalties and may even lose their license.
However, considering gray areas, consumers may still purchase THCa legally through online methods and some brick-and-mortar dispensaries, but they must be careful. Here are some things to consider.
- Purchase from a Brand That Uses Lab Testing. Lab testing provides transparency so you know exactly what’s in the cannabis you purchase. It ensures legality, purity, and potency. Lab test results are usually included on the brand’s website but may be ordered by request. All THCa products at Exhale Wellness are lab-tested for purity and potency.
- Buy from Trusted Brands. Reliable brands that have been in the industry for some time and are backed by positive customer reviews are more likely to sell legal, high-quality products.
Both consumers and vendors must also be accountable for understanding the law. After all, if you are caught with recreational marijuana in South Carolina, you can’t get excused by telling a law enforcement official you weren’t aware of the laws.
Consumers must research carefully to learn the legal status of the products they prefer. Vendors should also educate consumers through blog articles, knowledgeable budtenders, newsletters, and other materials.
