It is certainly possible to get arrested for having possession of a THC vape pen in the state of South Carolina. South Carolina law states that recreational marijuana is illegal, and possession of marijuana products containing more than 0.3% THC (tetrahydrocannabinol) may result in criminal charges. Because South Carolina has stricter marijuana laws than many other states, a THC vape pen can lead to arrest and may permanently stain your criminal record.
Questions like “is THC legal in SC” or “are weed pens illegal” come up frequently, especially as cannabis laws change across the country. If you or a loved one has been caught in possession of a THC vape, it is important to speak with an experienced criminal defense attorney who understands South Carolina drug laws and current enforcement trends.
What Is THC?
THC is marijuana’s primary psychoactive compound and has received increased attention in recent years. THC binds to receptors in the brain that affect pain, mood, memory, and coordination, which is why it produces a euphoric or “high” sensation.
Vaping THC typically involves inhaling THC vape oil or concentrated cannabis extracts using an electronic vaporizer. Since these concentrates are far more potent than traditional marijuana flower, law enforcement often treats vape cartridges as serious controlled-substance evidence, which is why people facing these allegations often seek guidance from an experienced drug lawyer.
In South Carolina, possession and use of THC remains illegal under most circumstances. Being found with a THC vaporizer, vape oil, or edible may lead to misdemeanor or felony charges depending on the amount involved, how the product is classified, and whether prosecutors allege intent to distribute.

Overview of South Carolina’s Marijuana and THC Laws
Possessing marijuana in South Carolina, regardless of where it was purchased, can result in criminal charges. This includes:
- Possession of marijuana or cannabis products
- Possession of drug paraphernalia, including vape devices
- Possession with intent to distribute (PWID)
- Trafficking or distribution of cannabis products
Under South Carolina law, marijuana is broadly defined to include:
- All parts of the cannabis plant
- Cannabis seeds
- Marijuana resin
- Extracts, concentrates, oils, and derivatives
- Any compound or preparation derived from marijuana
This broad definition is why THC vape pens, THC vape oil, and THC gummies are frequently treated the same as other marijuana products under state law.
Is Possession of a THC Vape Illegal in South Carolina?
Yes. It is illegal to possess cannabis in South Carolina in any form, including flower, edibles, tinctures, dabs, and vape liquids that contain more than 0.3% Delta-9 THC. This is why many people ask, “Are weed pens illegal?” and in most cases, the answer is yes.
South Carolina considers marijuana and high-THC concentrates to be Schedule I controlled substances. Possession of less than one ounce of marijuana or less than 10 grams of concentrate can result in a misdemeanor charge punishable by up to 30 days in jail and a $200 fine. Penalties increase significantly with larger quantities or prior offenses.
If you are accused of possessing a vape cartridge or small amount of cannabis, it’s important to understand what happens if you get caught with a small amount of marijuana in SC, since even minor quantities can still lead to criminal charges.

Distribution and Sale of THC Vape Products in South Carolina
The distribution and sale of THC vape products is prohibited under South Carolina law. Vape shop owners and individuals accused of selling or distributing THC products may face felony charges.
Possession of over one ounce of marijuana or more than 10 grams of concentrate may be charged as possession with intent to distribute or trafficking. Penalties can include mandatory minimum prison sentences, with exposure ranging from one year to decades, depending on quantity and prior convictions.
Selling THC products to a minor or within proximity to schools, playgrounds, or public parks can dramatically increase penalties and fines.

Delta-8, Delta-9, and Hemp-Derived THC in South Carolina
Many consumers ask, “Is Delta-8 legal in South Carolina?” or “Is Delta-9 legal in South Carolina?” While hemp-derived products were addressed under the 2018 Farm Bill, enforcement in South Carolina has become increasingly aggressive.
Delta-8 and certain Delta-9 products exist in a legal gray area, particularly when products are chemically converted or when lab testing reveals THC levels exceeding legal limits. Even products marketed as compliant may still result in criminal charges depending on testing methods and interpretation by law enforcement.
Because of this uncertainty, individuals and retailers should not assume that Delta-8, THC gummies, or vape products are automatically legal in South Carolina.
Recent Vape Shop Raids and THC Product Seizures Across South Carolina
In recent months, law enforcement agencies across South Carolina have conducted raids on vape shops, resulting in product seizures and criminal charges. These raids have targeted THC vape pens, THC vape oil, Delta-8 products, Delta-9 products, and THC gummies.
Charges often stem from laboratory testing that allegedly shows illegal THC concentrations. Touma Law Group has successfully defended vape shop owners and individuals in cases involving raids, seizures, and THC-related allegations by challenging search warrants, lab testing procedures, and improper classification of hemp products.

What Should I Do If I’ve Been Charged With Possession of a THC Vape in South Carolina?

An experienced criminal defense lawyer can:
- Review the legality of the search and seizure

- Challenge improper charges
- Seek dismissal, reduction, or alternative sentencing
Programs such as pretrial intervention may be available in some cases, but eligibility depends on the facts.

Frequently Asked Questions About THC Vape Pens in South Carolina
Is THC legal in South Carolina?
No. THC is illegal in South Carolina if it exceeds 0.3% delta-9 THC on a dry-weight basis. Recreational marijuana is not legal in the state, and possession of THC vape pens, THC vape oil, or other high-THC products can result in criminal charges.
Is delta-8 legal in South Carolina?
Delta-8 THC is currently legal in South Carolina if it is derived from hemp and contains less than 0.3% delta-9 THC. However, enforcement has become inconsistent, and delta-8 products are frequently seized during raids while testing is conducted.
This legal gray area has led to arrests and product seizures even when businesses believe they are operating lawfully.
Is delta-9 legal in South Carolina?
Delta-9 THC is only legal in South Carolina in very limited amounts when derived from hemp and kept below the 0.3% threshold. Any product exceeding that limit, including vape cartridges, gummies, or oils, is treated as illegal marijuana under state law.
Are THC gummies legal in South Carolina?
Generally, THC gummies are illegal in South Carolina if they contain more than 0.3% delta-9 THC. Even hemp-derived gummies may result in criminal charges if testing shows THC levels above the legal limit or if law enforcement disputes the product’s classification.
Why are vape shops being raided across South Carolina?
Law enforcement agencies across South Carolina have conducted vape shop raids and product seizures due to concerns about illegal THC content, mislabeling, and unverified lab testing. During these raids, officers often seize inventory, send products for testing, and pursue criminal charges against shop owners or employees.
