What is HHC?

Hexahydrocannabinol (HHC) is a hydrogenated form of tetrahydrocannabinol (THC), the primary psychoactive compound found in cannabis. HHC is produced through a process called hydrogenation, where hydrogen atoms are added to the THC molecule, altering its chemical structure and properties. 

This process can occur naturally in small amounts within the cannabis plant or be synthesized in a laboratory setting.

Legal Status and Regulation

It’s hard to determine the legal status of HHC because it depends on jurisdiction. In the United States, HHC derived from hemp that contains less than 0.3% delta-9 THC is federally legal under the 2018 Farm Bill. 

However, some states have imposed their own regulations or bans on HHC products. It's important for consumers and retailers to stay informed about the specific laws governing HHC in their region.

Different Forms of HHC Products

HHC is available in various forms, catering to different preferences and consumption methods. Some common HHC products include:

  • Vape carts. HHC vape cartridges are pre-filled with HHC oil and designed to be attached to standard vape pens or batteries. They offer a convenient, portable, and discreet way to inhale HHC vapor.
  • Tinctures. HHC tinctures are liquid extracts usually suspended in a carrier oil like MCT oil. They are taken orally, typically by placing a few drops under the tongue for sublingual absorption. Tinctures offer flexibility in dosing and can be mixed into food or drinks.
  • Edibles. HHC edibles include a wide range of products, including gummies, chocolates, brownies, cookies, and more. They offer a discreet and often delicious way to consume HHC, but the effects may take longer to kick in because of digestion. However, the duration of the effects is also longer than that of other methods.
  • Flower. The HHC flower consists of hemp buds that have been infused or sprayed with HHC distillate. It can be smoked or vaporized similarly to the traditional cannabis flower. This method is common among those who are used to smoking.

Will HHC Make You High?

The psychoactive effects of HHC are a topic of ongoing research and discussion. While there still aren’t a lot of scientific studies available on this topic, according to users, HHC can induce a range of effects, often described as a milder and more clear-headed high compared to traditional delta-9 THC.

According to these users, common effects include:

  • Euphoria - Feelings of happiness, well-being, and overall elevated mood.
  • Relaxation - A sense of calm and tranquility, often accompanied by muscle relaxation.
  • Altered perception - Changes in sensory perception, such as enhanced visual or auditory experiences.
  • Increased appetite - Commonly referred to as "the munchies," HHC may stimulate appetite and food cravings, just like THC.
  • Analgesia - According to some users, HHC has pain-relieving effects.

However, it's important to understand that there are a lot of different factors that can influence the intensity and duration of this compound, including:

  • Dosage - The amount of HHC a person consumes plays a crucial role in determining the strength of the effects. Higher doses generally lead to more pronounced psychoactive experiences.
  • Individual tolerance - Every person has different sensitivities to HHC, and those who have a higher tolerance need larger doses to experience the same effects.
  • Consumption method - The way HHC is consumed can influence its onset and duration of effects. Vaping or smoking may lead to a faster onset but shorter duration compared to edibles.
  • Product quality - The purity and quality of the HHC product can also influence its effects. Products from reputable brands are generally more likely to deliver consistent and predictable experiences.

Where is HHC Found?

HHC's availability is expanding rapidly. Not too long ago, you could only find it in specialty shops or online retailers. Now, you can find HHC products in the:

  • Vape shops - Many vape shops have embraced HHC and now sell a variety of vape cartridges, disposables, and e-liquids infused with the cannabinoid.
  • Gas stations and convenience stores - Surprisingly, HHC has found its way onto the shelves of many gas stations and convenience stores, often in the form of gummies, vapes, or pre-rolled joints.
  • Tobacco shops - Some tobacco shops have also started carrying HHC products.
  • Online Retailers - Of course, the internet remains a primary source for HHC, with countless online stores specializing in hemp-derived products offering a wide selection of HHC goods.

It's important to note that HHC's legal status varies by state and country, so if you’re thinking about buying and consuming any HHC products, you will first need to research the regulations in your area.

Is HHC a Form of THC?

HHC is closely related to THC, but it is not technically the same compound. HHC is a hydrogenated form of THC, which means that it has been chemically modified by adding hydrogen atoms to its structure. This alteration creates a distinct molecule with its own unique properties.

However, HHC and THC share a similar molecular structure and interact with the body's endocannabinoid system in comparable ways. This is why HHC is believed to produce effects similar to THC, including potential psychoactive and therapeutic properties.

CBD Products Containing HHC

While HHC is often marketed as a standalone product, it can also be found in some full-spectrum CBD products. These products contain a wide range of cannabinoids and other compounds found naturally in hemp, including trace amounts of HHC. However, the concentration of HHC in these products is typically much lower than in dedicated HHC products.

How Long Does HHC Last in Your System?

The duration that HHC stays detectable in your system can vary depending on several factors, including:

  • Frequency of use. The more often you use HHC, the longer it will take to clear from your system.
  • Dosage. Higher doses of HHC may take longer to metabolize and excrete compared to lower doses.
  • Individual metabolism. People metabolize substances at different rates, which can affect how long HHC stays in their bodies.
  • Body fat percentage. HHC is fat-soluble, so individuals with higher body fat percentages may store HHC for longer periods.

While there is limited research on the exact duration of HHC in the body, anecdotal evidence and estimates suggest that it may be detectable in urine for up to several weeks after last use. However, the window of detection may be shorter for blood or saliva tests.

It's important to consult with a healthcare professional or a qualified lab for specific information regarding HHC detection times.

Drug Testing Methods

There are a lot of different methods that can be used to detect the presence of drugs in the body, each with its own level of specificity and sensitivity. Common drug testing techniques include:

  • Urine tests - Urine tests are the most commonly used method for drug screening because they’re non-invasive and can also detect a wide range of substances. They analyze urine for the presence of drug metabolites, which are byproducts of the body's breakdown of drugs.
  • Blood tests - Blood tests are more invasive but offer a higher level of accuracy and can detect recent drug use. They measure the concentration of the parent drug or its metabolites in the bloodstream.
  • Saliva tests - Saliva tests are less invasive than blood tests and can detect recent drug use. They analyze saliva for the presence of the parent drug.
  • Hair tests - Hair tests offer the longest window of detection and can even reveal drug use over several months. They analyze hair follicles for the presence of drug metabolites.

Specificity and Sensitivity of Tests

The specificity of a drug test refers to its ability to accurately identify a specific substance, while sensitivity refers to its ability to detect even small amounts of the drug. Different testing methods have varying levels of specificity and sensitivity for HHC.

Standard urine tests that screen for THC may not specifically identify HHC, as they are designed to detect THC metabolites. However, more specialized tests that target specific HHC metabolites are becoming increasingly available.

Challenges in Detecting HHC

Detecting HHC presents unique challenges because it has started gaining popularity very recently, and there’s a clear lack of standardized testing procedures. Some standard drug tests may not differentiate between HHC and other THC isomers, leading to potential false positives. 

Additionally, the specific metabolites of HHC are still under investigation, which makes it very difficult to develop highly accurate and specific tests.

Factors Affecting HHC Detection

The detectability of HHC in drug tests is influenced by several different individual, behavioral, and methodological factors. 

Anyone who is looking to accurately interpret test results or just wants to make informed decisions about HHC use needs to understand all these factors.

So, let’s take a closer look.

Metabolism and Excretion Rates

The human body processes HHC through metabolism, primarily in the liver. The rate at which HHC is metabolized and excreted can vary significantly from person to person due to genetic differences, liver function, age, and overall health. 

People with faster metabolisms may clear HHC from their system more quickly, while those with slower metabolisms might retain detectable levels for longer periods.

Frequency and Duration of HHC Use

People who consume HHC regularly are more likely to have detectable levels of HHC metabolites in their system for extended periods compared to occasional users. The amount of HHC consumed in each session also plays a role, with higher doses generally taking longer to clear from the body.

Hydration and Exercise

Staying well-hydrated can help flush out metabolites through urine, potentially shortening the detection window. Additionally, regular exercise may increase metabolism and promote faster elimination of HHC from the body.

Influence of Testing Methodologies and Thresholds

Different drug tests vary in their sensitivity and cut-off thresholds for detecting HHC metabolites. More sensitive tests, such as gas chromatography-mass spectrometry (GC-MS), can detect lower concentrations of HHC metabolites and may extend the detection window compared to less sensitive tests like immunoassays. 

The specific cut-off thresholds used by labs can also vary, which would complicate the interpretation of test results even further.

Other Factors

In addition to the factors mentioned above, other variables can affect HHC detection, including:

  • Body fat percentage: HHC is fat-soluble, which means it can accumulate in body fat. People with higher body fat percentages may store HHC for longer periods, potentially leading to prolonged detection times.
  • Time of last use: The closer the drug test is to the last HHC use, the higher the likelihood of detection. The detection window gradually decreases as time passes since the last consumption.
  • Individual variations: Everyone has unique body chemistry, and individual variations in metabolism, excretion, and other factors can influence HHC detection times.


The question of whether HHC shows up on a drug test is complex and nuanced. While standard THC tests may not specifically identify HHC, specialized tests are emerging that can detect HHC metabolites. 

It's important to understand that a positive HHC test result doesn't necessarily equate to recent or heavy use. The interpretation of test results requires a nuanced understanding of the various factors at play. As HHC continues to gain popularity, further research and standardized testing procedures are needed to provide clearer answers and guidelines regarding its detection.
