THC-H is a cannabinoid of the Delta-9 category, which is a primary psychoactive compound of cannabis. It is responsible for creating a high effect when a person consumes marijuana. In this article, we will study its origin, potency compared to other cannabinoids, benefits, and effects. Read on to get insights on THC-H and make an informed decision.

Overview: What Is THC-H?

THC-H is a cannabinoid of cannabis found in 2020 by researchers in Italy. This cannabinoid is still under study hence, the complete effects are not known, but it is related to the THC category, so we can conclude some basic results. THC-H (Tetrahydrocannabihexol) is found in a strain of marijuana that is responsible for creating the ‘high’ effect.

Carbon Atoms

THC-H has a longer n-hexyl chain consisting of 6 carbon atoms, whereas THC has a pentyl chain consisting of 5 carbon atoms. This minor difference has a huge impact on the effect and potency of THC on the body and mind.

Natural Availability

Tetrahydrocannabihexol is found in a meager quantity in the FM2 strain of marijuana, which is available only in Italy. Its quantity is so low that it is impossible to produce it in bulk for medicinal, therapeutic, and other purposes. Hence, if you find a product labeled with THC-H, it is highly probable that it is not natural and prepared synthetically in the lab with chemical modifications.


As discussed above, THC-H has a longer carbon chain than THC, which makes it more potent. A minor yet significant variation in chemicals greatly impacts how THC-H affects the body. THC-H is highly effective in generating a feeling of being “high,” and it attaches to cannabinoid receptors in the brain even more efficiently than regular THC, with an approximately 10% better attachment rate.


  • THC-P has a longer side chain (7 carbon atoms), whereas THC-H has a bit smaller chain of 6 carbon atoms.
  • THC-H makes you feel high. THC-P also makes you feel high and has intense psychoactive effects, but these are more intense than THC-H.
  • THC-H binds with CB1 and CB2 receptors strongly, whereas THC-P binds even stronger than THC-H.

Legality Of THC-H

The hemp plant is a major source of psychoactive substances (phytocannabinoids), which was legalized by the Farm Bill 2018 in the USA. It is legal if the product contains 0.3% or less than this Delta-9 content. However, some states have passed their own laws to regularize the cannabis market. You need to be aware of the local laws and regulations before carrying, buying, or consuming THC.

Drug Detection Test: Is THC-H Detectable?

Standard drug tests typically target delta-9 THC but may detect THC-H due to its similarity. Detectability can vary based on factors such as the testing method and the amount consumed. As a new cannabinoid, THC-H may not be specifically targeted in some drug tests but may be included in future screenings.

Bottom Line

THC-H is a recently found cannabinoid known for its psychoactive effects because it is similar to Delta-9 THC. There is not much information about its effects, legality, and detection in drug tests, but one thing is certain: it is more potent than THC due to its longer carbon atom tail. People should wait for the concrete results to adapt this newly found cannabinoid into their routine.


How THC-H is different from THC?

THC has a 5-carbon atom pentyl chain, and THC-H has a 6-carbon atom hexyl chain. Due to this, THC-H is more potent than THC and has more intense psychoactive effects.

What is the legal status of THC-H?

The legal status specific to THC-H is not clear yet however, Delta-9 THC is legal to 0.3% according to the Farm Law 2018. However, this status may change based on the local rules and region.

In which strain of marijuana do researchers find THC-H?

Researchers found a meager presence of THC-H in the FM2 strain of marijuana.
