How Many Types of THC Are There?

Key Takeaways:

• THC is a family of compounds with multiple types, like Delta-8, Delta-9, THCA, and THCP.
• While some THC variants are mild and federally compliant under the 2018 Farm Bill, others are far stronger and legally restricted in certain states.
• Knowing about the different forms of THC can help you choose the best one for your goals and tolerance level.

What comes to mind when you think of THC? It could be a nice euphoric buzz, a giggly feeling, those unmistakable munchies, or even something more therapeutic like stress relief or better sleep.

But did you know THC is actually a blanket term used to describe a wide variety of psychoactive cannabinoids? That’s right, there isn't just one form of THC. In fact, there are quite a few.

Different Types of THC Explained

THC, short for tetrahydrocannabinol, refers to a group of compounds that interact with CB1 and CB2 receptors in the body’s endocannabinoid system, which is the network responsible for regulating mood, perception, and appetite.

While Delta-9 THC is the most recognized form, scientists have identified several variants, each with unique chemical structures and effects.

1. Delta-9 THC

Delta-9 is the classic, full-bodied form of THC most people associate with marijuana. It produces euphoric, relaxing, and appetite-stimulating effects that can last 2-8 hours, depending on the dose and consumption method.

Because Delta-9 binds strongly to CB1 receptors, its effects are intense and long-lasting. Studies confirm that it plays a mood and perception-changing role using our dopamine signaling pathways.

However, some users experience anxiety or couch-lock at higher doses.

Delta-9 products are typically regulated in legal cannabis markets, though hemp-derived products are available within the 2018 Farm Bill limits.

2. Delta-8 THC

Delta-8 is about half as potent as Delta-9 and produces a smoother, clearer high. Many users call it “diet weed” because it offers relaxation and mild euphoria without overwhelming intensity.

Because it metabolizes differently in the liver, Delta-8 produces milder psychoactive effects. This makes it great for daytime use or creative focus, and it’s generally considered more balanced and approachable for beginners.

3. Delta-10 THC

Delta-10 has light, uplifting effects, which are much like sativa. Though research is still limited, studies say it interacts more weakly with CB1 receptors, promoting clarity and motivation rather than heavy sedation.

4. THCA (Tetrahydrocannabinolic Acid)

THCA is the raw, non-psychoactive precursor to THC. When heated through smoking, vaping, or decarboxylation, it converts into Delta-9 THC.

Since it’s non-intoxicating in its natural form, THCA is sometimes used solely for its anti-inflammatory and neuroprotective benefits. Thanks to the Farm Bill, hemp-derived THCA products are legal.

5. THCP (Tetrahydrocannabiphorol)

THCP is one of the most potent cannabinoids ever discovered, binding to CB1 receptors up to 33 times more effectively than Delta-9. Even small doses can cause powerful, long-lasting euphoria.

Due to its intensity, THCP is best suited for experienced users who prefer deep body relaxation and extended highs.

6. THCV (Tetrahydrocannabivarin)

THCV behaves differently from traditional THC compounds. At low doses, it can suppress appetite and increase energy, making it popular for active users. At higher doses, it becomes mildly psychoactive, producing a shorter, more stimulating high.

Early research also suggests that it may influence metabolism and blood sugar regulation.

7. THCO (Tetrahydrocannabinol Acetate)

THCO is a synthetic derivative of THC created by adding an acetyl group to the molecule. This modification allows it to cross the blood-brain barrier more efficiently, often resulting in a stronger, dreamlike high.

THCO is currently federally illegal in the United States.

8. Delta-11 THC

Delta-11 has a milder onset and longer duration compared to other THC variants. It’s known for gentle relaxation without anxiety or paranoia. Some users describe it as the perfect middle ground between Delta-8 and Delta-9. It’s known for gentle cerebral uplift and relaxation without intense body heaviness.

Which Type of THC Is Right for You?

Each of the forms of THC offers its own benefits and intensity level. See below for a quick summary of each type’s characteristics.

Always Choose Lab-Tested, Compliant THC

While THC might seem like one thing to most people, it’s actually a family of compounds that interacts differently with your mind and body. Knowing the different types of THC can help you make more informed and responsible choices. The important thing for consumers is to always research credible, lab-tested products and stay updated on changing state policies.

As cannabis science continues evolving, we’ll hopefully learn more about the therapeutic benefits of these THC variants.
