Cannabis laws can be confusing, especially when it comes to THCa vs. THC. Some people assume THCa is illegal because it’s connected to THC. Others think it’s a legal loophole. So, what’s the truth? Is THCa legal?
The answer isn’t simple. It depends on where you are and how you use it. At Sherlocks Glass & Dispensary, we believe in transparency. That’s why we provide clear information about THCa flower so you can make informed decisions about what’s right for you.
Let’s break it down.
THCa and the 2018 Farm Bill
Federal laws control what’s legal and what’s not in the United States. The 2018 Farm Bill changed everything for hemp and cannabis products. The government considered all cannabis-related products illegal before this law was passed. However, the Farm Bill removed hemp from the controlled substances list, making it legal as long as it contains less than 0.3% Delta-9 THC by dry weight. This law opened the door for a variety of cannabinoid products, including CBD, Delta-8, and THCa. The Farm Bill is also why you walk into a dispensary in North Carolina and try different strains like Lemon Cherry Gelato, Candy Gelato, and Tropicana Cherry!
Since THCa is not Delta-9 THC, many believe it falls within the legal hemp category. That’s why you shops selling THCa flower, vapes and concentrates in states where cannabis itself is restricted.
THCa vs. THC: Why It Matters for Legal Status
Understanding the difference between THCa and THC is key to knowing why THCa sits in a legal gray area. While THCa is federally legal, its legal status depends on how the law defines THC and how a state chooses to regulate it.
THC Only Appears After Heat Is Applied
THC is the psychoactive form of cannabis, and it only appears when you heat THCa through smoking, vaping, or cooking. This process converts the non-psychoactive THCa into active THC, creating the effects cannabis is known for.
This is where legal confusion begins. If THCa flower contains very little Delta-9 THC in its raw form, it meets legal requirements. But once it’s smoked or vaped, its THC levels increase. Some states see this as a loophole and regulate THCa as if it were already THC.
Some States Focus on the Final Product, Not the Raw Numbers
While federal law focuses on the chemical composition of raw cannabis, some states take a different approach. They regulate cannabis based on how it will be used instead of measuring how much Delta-9 THC is present.
This means some states have banned THCa flower entirely, arguing that its intended use—smoking or vaping—turns it into THC anyway. They see THCa products as just another way to access high-THC cannabis, even if it technically follows federal hemp laws.
Is THCa Legal in North Carolina?
Yes, THCa flower is legal in North Carolina. North Carolina follows the 2018 Farm Bill, meaning hemp-derived products with less than 0.3% Delta-9 THC by dry weight are legal. Since THCa isn’t Delta-9 THC until it’s heated, it meets that requirement.

In 2022, the North Carolina General Assembly removed hemp from the controlled substances list, making THCa flower legal in the state. However, that doesn’t mean the laws won’t change. Cannabis regulations are constantly evolving, and some lawmakers have pushed for stricter control over THCa products. You can legally buy and use THCa in North Carolina.
Can You Travel with THCa?
Traveling with THCa can be risky. Even if it’s legal in your state, airport security and law enforcement may not know the difference between THCa flower and traditional cannabis. If they test it and find it converts to THC when heated, you could run into problems—especially in states where cannabis is illegal.
If you’re flying or crossing state lines, leaving your THCa at home is best unless you’re 100% sure it’s legal at your destination.
Why Some States Allow THCa and Others Don’t
The way some states regulate THCa explains why it’s legal in some places and restricted in others. States that follow federal hemp guidelines allow THCa products, while others apply stricter regulations to prevent its sale.
This legal gray area has made THCa one of the most debated cannabis compounds in the industry. Some states view it as a legal hemp product, while others see it as THC in disguise. Before you buy or travel with THCa, it’s always best to check your local laws. Some places classify it based on how people use it. For example, some states measure the THC content in its raw form, while others decide legality based on what happens after heating.
What States Have Banned THCa?
Laws change all the time. Some US states have taken steps to ban or restrict THCa. These states argue that THCa is just another way to access THC, so they don’t allow it—regardless of whether it meets the 2018 Farm Bill’s hemp guidelines.
While laws vary, states that have banned or restricted THCa flower include:
- Idaho
- Nebraska
- Arkansas
- Oregon (some restrictions)
- California (some restrictions)
Always check your local laws before buying or traveling with THCa.
