H4CBD is one of the newest exotic cannabinoids making news in the industry. Although scientists have known about H4 CBD (also known as H4-CBD, H4CBD, and THD) since the 1940s, this hydrogenated form of CBD only recently entered the mainstream spotlight. With anecdotal sources saying H4CBD is 100 times more effective than CBD and similar to THC, it’s no wonder this hemp-derived synthetic cannabinoid has everyone’s attention. 

This guide examines H4-CBD from every angle, explaining its effects and chemical structure, user reviews, comparison to CBD and THC, and commercial products.

What is H4CBD?

H4CBD or (Tetrahydrocannibidiol, H4-CBD, THD or hydrogenated CBD) is synthesized hydrogenated CBD. Manufacturers create H4 CBD by adding four hydrogen atoms to CBD molecules to convert some of the double bonds into single bonds. 

This process causes a chemical reaction that changes the active cannabinoid into a different, usually stronger one. As a result, H4CBD is a more potent than CBD.  It is important to note that H4CBD is a new compound. It is not "a form" of CBD.

H4-CBD Mechanism of Action

Most information regarding H4CBD is derived from a single study conducted in 2006. The research team found that this alternative cannabinoid has a significant affinity for CB1 endocannabinoid receptors in the brain, akin to THC. Some have suggested that this binding could explain the compound’s reported psychoactive effects.

Many H4CBD users describe the H4CBD cannabinoid experience as similar to a 2:1 CBD-to-THC product. CBD’s familiar non-intoxicating, therapeutic effects are still dominant. Still, there’s a slight sense of intoxication and mild euphoria similar to low doses of THC. 

H4CBD compared to CBD: 

H4CBD and conventional CBD share many similarities but are not the same molecule. CBD and H4CBD come from hemp, but H4CBD undergoes a synthetic chemical process to reach its final potent form. 

The 2006 study found that H4 CBD binds with the brain’s CB1 receptors with 100 times greater strength than regular CBD. 

H4 -CBD compared to Delta-9 THC: 

Although H4CBD might bind with CB1 receptors about 100 times stronger than CBD, this affinity level is nowhere near as high as Delta-9 tetrahydrocannabinol (THC). H4 CBD users and a 2017 research review echoed that H4 CBD feels similar to many minor cannabinoids and low-potency THC alternatives on the market.


H4CBD doesn’t elicit the same psychotropic effects as THC. But the H4-CBD cannabinoid is psychoactive compared to regular CBD. Overall, according to user feedback, it would be safe to say that H4CBD might offer something in the range of three times the potency of CBD. 

Molecular Structure

Cannabis scientists structurally alter CBD  to create H4 CBD by adding four hydrogen atoms to the head of the CBD molecule in a process called “hydrogenation.” The method used to make H4CBD is similar to making margarine from vegetable oil. As a result, H4CBD is technically a synthetic cannabinoid. 

Those familiar with HHC know that it is the hydrogenated form of THC. H4 CBD is made using the same process as HHC Only it starts with hemp-derived CBD. 

H4 CBD Legality

Many hemp-derived synthetic cannabinoids like H4 CBD exist in a legal gray area. Overall, CBD and other cannabinoids from hemp are federally legal under the 2018 Farm Bill, as long as the products contain no more than 0.3% Delta-9 THC by dry weight. 

However, some states have enacted laws restricting or banning hemp-derived cannabinoids such as Delta-8 THC due to their synthetic production methods and psychoactive properties. Some of these laws could affect hydrogenated cannabinoids such as H4 CBD.

H4 CBD Availability and Products

H4-CBD is one of the newest exotic cannabinoids in the hemp industry. CannaAid was the first to sell H4 CBD products, introducing lines of H4 CBD vapes and H4 CBD gummies. 

Still, H4 CBD is an up-and-coming cannabinoid gaining much attention from extractors. As the demand for H4CBD grows, more brands will develop more products. 

H4CBD products available online include:

  • Distillates
  • Vape cartridges
  • Tinctures
  • Oils
  • Concentrates
  • Gummies and edibles

The Bottom Line

CBD is a beneficial cannabinoid for those seeking relief from inflammation, anxiety, insomnia, and more. However, consumers with more chronic conditions might want something more powerful, albeit without THC’s intense effects. H4-CBD may be best for consumers who enjoy the effects of CBD but seek something slightly more robust, with just a hint of psychoactivity and euphoria. 

Consumers should only buy from trusted brands that offer full-panel lab-test results and a certificate of analysis (COA). ACS Laboratory is the most trusted cannabis and hemp testing laboratory in the US, providing cutting-edge testing capabilities to ensure safety and consistency.
