- Hexahydrocannabinol (HHC) is a hydrogenated form of THC mostly made by chemically adding hydrogen to Delta-8 or Delta-9 THC, which changes its molecular structure.
- HHC tends to produce a milder, smoother experience than Delta-9 THC, often described as sitting between the calm of Delta-8 and the potency of Delta-9.
- Because HHC is newer and less studied, there’s still limited research on its safety or long-term effects; if using it, start with a low dose and proceed cautiously.
With more than 100 cannabinoids available, it’s normal to feel unsure about what fits your needs. Some people find Delta-8 to be underwhelming, while others find Delta-9 to be too potent. Luckily, there’s a middle ground option: HHC.
What is HHC?
HHC, short for hexahydrocannabinol, is one of the many compounds found in the cannabis plant. This naturally occurring cannabinoid interacts with the body’s endocannabinoid system (ECS), a network of receptors responsible for various functions, including learning, eating, and sleeping. This interaction produces both the familiar cannabis high and potential therapeutic effects.
While you’ll find many reports online stating the psychoactive properties are 70% to 80% as potent as Delta-9 THC, the compound most associated with marijuana, there aren’t any scientific findings that quantify its potency. Early research from the 1970s found that some HHC isomers produced THC-like responses in animals, but no potency was confirmed.
Anecdotally, however, users say it’s the perfect balance for those who want something stronger than Delta-8 but less overwhelming than Delta-9.
How is HHC Made?
Although HHC is naturally present in cannabis, the concentration is too low for practical extraction. That’s why companies rely on lab processes such as:
1. Hydrogenation of THC
This process adds hydrogen atoms to THC, stabilizing the molecule by replacing double bonds with single bonds. It requires a catalyst, such as palladium or platinum, and is conducted under high pressure.
Because HHC undergoes hydrogenation, which adds hydrogen atoms to its molecular structure, it's more stable and more resistant to heat and light degradation than THC.
2. Conversion from CBD
Another method is synthesizing HHC from CBD using hydrogenation or other specialized processes. This approach eliminates some legal restrictions tied to THC and allows for a more controlled production process.
3. Alternative Methods
Some companies experiment with terpene-based synthesis, using compounds like citronellal or L-carvone. However, these methods remain less reliable, so hydrogenation and CBD conversion remain the industry standard.
Will HHC Get You High?
Yes, HHC does produce a high. Most users describe it as more subtle than Delta-9 but stronger than Delta-8. You can generally expect effects such as:
- Elevated mood
- Altered perception
- Relaxation without heavy sedation
- Increased appetite
- Slowed reaction times
Many consider HHC’s high to be clear-headed and energizing, often compared to a Sativa-like buzz that can enhance creativity and focus. Indica-dominant HHC strains, on the other hand, may offer a more relaxing and euphoric experience.
How much HHC you take, and your method of consumption, also shape your experience:
- HHC vape pens or flower: Effects are generally felt within 5 minutes, lasting a few hours.
- HHC gummies: Typical onset in 30 to 60 minutes, but effects can last up to 6 hours.

Are There Any Side Effects of HHC?
HHC is generally considered safe, especially compared to Delta-9 THC. However, some users may experience mild side effects, including:
- Dry mouth or red eyes
- Dizziness
- Increased appetite
- Impaired motor skills
- Rare mood disturbances or anxiety
Because the scientific literature on HHC is still developing, most safety insights come from comparing it to other THC analogs. For example, hydrogenated cannabinoids suggest they may have similar pharmacological activity to THC, though this requires more research to be certain.
Potential Benefits of HHC
While research on HHC is still limited, early evidence and user reports suggest potential therapeutic uses such as:
- Pain relief
- Stress and anxiety reduction
- Sleep support
- Appetite stimulation
- Anti-inflammatory properties
- Neuroprotective effects
- Nausea prevention

If you're exploring cannabinoids and want something more balanced to try, HHC is a reasonable place to start.
FAQs
Is HHC Legal?
Yes. HHC is federally legal under the 2018 Farm Bill, provided it’s hemp-derived and contains less than 0.3% Delta-9 THC on a dry-weight basis. While legal at the federal level, laws are constantly evolving, so it’s best to stay informed about state-specific regulations.
Does HHC Show Up on a Drug Test?
Unfortunately, yes. HHC breaks down into metabolites similar to THC, which drug tests are designed to detect. Different factors impact how long HHC stays in your body like:
- Dosage
- Frequency
- Metabolism
- Body composition
For some, it may take a few days, while heavy users may need a month or longer before testing clean.
How Long Does an HHC High Last?
The duration of the high can last between a couple hours to almost 6 depending on your unique biology, how much HHC you’ve used, and the form you’ve consumed. Smoking or vaping HHC can produce an experience that generally lasts between 1-3 hours. Eating HHC often gives you a longer high of up to 6 hours.
