What is THC-B: Composition, Effect, Legality

Surely you've already explored the benefits of CBD and THC and want to discover new horizons? It's true that it's easy to get lost among all these molecules, but we're here to light your way! So, what's THC-B?

What is THC-B?

THCB, or Tetrahydrocannabutol, is a cannabinoid found in very small quantities in the hemp plant. Its chance discovery in 2019 by a group of Italian researchers while studying a variety of cannabis called FM2 sparked great interest in the field of medical cannabis research, overseen by the Italian government.

Like THC-P, THC-B is found in trace amounts in most cannabis flowers, in concentrations of less than 0.1%. This low presence makes its direct extraction for commercial purposes almost impossible. For this reason, it is considered a secondary cannabinoid and is classified as a semi-synthetic cannabinoid. Although it exists naturally, its synthesis in the laboratory is necessary to make it marketable.

Composition of THC-B

THC-B is a homologue of THC (delta-9-THC), a well-known psychoactive cannabinoid. The term "homolog" refers to chemical compounds similar in structure and properties.

This cannabinoid is distinguished from THC by its butyl side chain, unlike the pentyl side chain found in tetrahydrocannabinol. Although its chemical structure is similar to that of THC, THC-B has a shorter side chain, made up of four carbon atoms instead of five.

What's more, unlike THC, which is widely used in cannabis, THC-B is much rarer and harder to find on the market. THC-B synthesis does not simply involve adding extra carbon atoms to the delta-9-THC molecule. On the contrary, it involves using a synthetic substance as a precursor, already possessing the appropriate number of carbon atoms. This chemical process, known as "terpenylation", enables THC-B to be produced in the laboratory in a controlled and precise manner.

Effects of THC-B

THC-B has a stronger binding affinity with CB1 receptors than THC, suggesting different potential effects on the body. THC-B's unique structure, with its shorter side chain, suggests slightly milder psychoactive effects in theory.

Based on user testimonials, THC-B also seems to have an impact on perception and mood. It is reported to induce feelings of euphoria, boost energy and creativity, promote relaxation and relieve pain symptoms.

Legal status: is THC-B legal? 

For the time being, THC-B is not classified as a narcotic, like THC or HHC. This means that it is not currently banned for sale or consumption, nor is THC-P, another cannabinoid in the same family.

However, it's important to keep abreast of the ever-changing laws and regulations in your area regarding cannabinoids. 

Screening tests

Since THC-B has not yet been widely studied, it's difficult to determine whether its consumption will result in a failed drug test. However, it's important to note that, in general, the presence of any cannabinoid in your system can potentially trigger a positive result on these tests.

Remember that THC-B is a psychoactive cannabinoid, which means it can alter your perception. It is therefore imperative never to consume it before driving or performing any task requiring heightened alertness.


With its beneficial effects, THC-B opens new doors in the exploration of its benefits.. Explore the possibilities offered by THC-B to improve your daily life in a responsible way!
