- Which Is Better — HHC or THC?
There are over 100 identified cannabinoids in the cannabis plant (1). You’re probably familiar with compounds like THC (tetrahydrocannabinol) and CBD (cannabidiol), but what about HHC (hexahydrocannabinol)?
While HHC is naturally occurring, it’s only in very small amounts. It’s so microscopic, in fact, that you couldn’t actually extract enough of it from a plant to feel anything. That’s why all of the HHC products on the market are made in a lab, which makes them semi-synthetic
In this HHC vs THC explainer, we’re walking through details like potency, legality, effects, and more.
What Is HHC?
Hexahydrocannabinol, or HHC, is a very trace cannabinoid in both hemp and marijuana plants (2). It’s technically a hydrogenated form of THC, which just means the molecule has extra hydrogen atoms.
How Is HHC Made?
HHC is found in minute amounts in cannabis plants, so manufacturers don’t extract it directly. To make HHC in usable amounts, they convert hemp-derived CBD into a cannabinoid that’s similar to THC. Then, manufacturers use a catalyst to add hydrogen molecules. This is the hydrogenation process that ultimately produces HHC.
Hydrogenation also makes the new compound more heat-, light-, and oxygen-resistant. Those things degrade THC and other cannabinoids, which is why HHC products usually have a longer shelf life.
Is HHC a Natural or Synthetic Cannabinoid?
HHC is actually both natural and semi-synthetic. It does occur in very small amounts in cannabis plants, particularly as other cannabinoids age over time. But it’s not present in sufficient quantities for extraction.
That’s why the HHC in any product on the market is made in a lab. It’s described as semi-synthetic because it starts with a natural compound—hemp-derived CBD—before being chemically converted.
Does HHC Get You High Like THC?
Yes, HHC is intoxicating, just like THC. It can produce similar effects, like euphoria, relaxation, altered sensory perceptions, an appetite boost, and even mild pain relief. But it produces milder psychoactive effects, and most people report that HHC has a more functional experience. That’s dose-dependent, of course.
What Is THC?
THC is short for tetrahydrocannabinol. It’s probably the most famous cannabinoid of them all. As the primary psychoactive compound in the cannabis plant, THC is what we’re talking about when we reference getting “high.”
THC interacts with receptors in the body’s endocannabinoid system (specifically CB1 receptors in the brain). This system regulates mood, appetite, memory, sleep, pain response, and more. By binding well with these receptors, THC creates those euphoric sensations.
Like HHC, THC is naturally occurring in cannabis, but in much higher concentrations.
Types of THC: Delta-9, Delta-8, and Beyond
There are different types of THC. They have a similar chemical structure with minor differences in the arrangement of their atoms. Those differences affect how well each type binds to receptors in the body's endocannabinoid system, which is why effects can vary widely.
- Delta-9 THC is the primary, traditional type. It’s found in low amounts in hemp plants and much higher concentrations in marijuana. It’s very intoxicating, with potent psychoactive effects.
- Delta-8 THC is only present in small amounts. Like HHC, Delta-8 THC in commercial products is usually made with hemp-derived CBD. It creates milder euphoric effects than Delta-9.
- Other THC compounds, like Delta-10 or THCP, occur in low concentrations or are produced in a lab. Effects vary in intensity and duration.
THC’s Role in Cannabis Effects
When we think about effects from cannabis, we’re usually thinking about the pronounced psychoactive effects of THC. It’s the main compound responsible for intoxication in cannabis.
The classic “high” is characterized by euphoria, altered perceptions, increased appetite (the “munchies”), relief of tension, and relaxation.
In higher doses and depending on individual sensitivity, THC can also trigger anxiety, paranoia, panic attacks, impairment, a rapid heartbeat, and short-term memory issues.
THC Products: Edibles, Vapes, Tinctures
THC products are diverse and come in forms for inhalation, ingestion, sublingual use, or topical application. The consumption method affects the overall experience, especially potency and duration.
- Inhaled THC typically kicks in within minutes and lasts a few hours.
- Ingested THC, like gummies or drinks, is usually noticeable within 30 minutes to 2 hours. THC beverages made with nanoemulsion technology are often noticeable in 15 to 30 minutes. Effects from traditional edibles tend to be long-lasting, between 6 and 8 hours, and noticeably more potent. That’s because of how ingested THC is metabolized in the liver.
- Tinctures and sublingual THC have a fairly rapid onset, usually 15 to 45 minutes, and often last 4 to 6 hours.
- Keep in mind that exact timelines are personal.
Key Differences Between HHC and THC
HHC is a hydrogenated form of THC, which means it has extra hydrogen atoms (with commercial HHC products, that’s a chemical process that occurs in a lab).
Both cannabinoids bind to the same main receptors in the endocannabinoid system, but the minor structural difference alters the strength of that binding and the overall experience. THC is known for its pronounced psychoactive effects, while HHC tends to deliver a milder psychoactive experience.
Potency Comparison: Is HHC Stronger Than THC?
No, HHC isn’t usually as strong as THC. For some people, that’s actually part of its appeal. While effects are noticeably intoxicating, they aren’t often as intense as THC.
Think of HHC intensity as somewhere between Delta-8 and Delta-9.
Psychoactive Effects: How Do They Feel?
Psychoactive effects from cannabis are often described as euphoric, mood-boosting, and relaxing. Altered perceptions are also common.
With THC, these effects can also be impairing and may trigger anxiety in high doses. Psychoactive effects from HHC tend to be clearer and not as mentally overwhelming.
Remember that cannabis effects vary depending on things like dosage, consumption habits, metabolism, and personal sensitivity levels.
How Long Do HHC and THC Last?
The duration of effects from HHC and THC has a lot to do with how you consume them. Inhaled forms reach peak levels and fade more quickly, within a few hours, while ingested forms last significantly longer (6 to 8 hours).
Some people report that HHC appears to taper more gradually than THC, but current research suggests that effects are largely comparable (3). Any differences in duration are probably more due to dose, consumption method, and individual metabolism than to the molecule itself.
Chemical Structure and Stability
Hydrogenation is the key differentiator between HHC and THC. More hydrogen atoms in HHC make this compound more resilient, so it’s not as likely to degrade under exposure to light, heat, and oxygen.
Still, it’s best practice to store hemp-derived products properly to maintain their quality and potency.
HHC vs THC: Safety & Side Effects
Since HHC and THC bind to the same cannabinoid receptors, they seem to have similar safety profiles. But remember that HHC isn’t nearly as well researched as HHC, so we really don’t have long-term data.
Is HHC Safer Than THC?
There’s no research that confirms HHC is safer than THC. But because its effects can be milder, some people think it’s lower risk. It’s still a bad idea to do anything that requires a clear mind, like driving or making big decisions.
Reported Side Effects of Each
Both HHC and THC interact with CB1 receptors in the brain, which means their effects are pretty comparable.
Aside from psychoactive effects like euphoria, tension relief, and relaxation, you’ll probably also notice reddened eyes and a dry mouth. Negative effects, which are more likely in higher doses, can include a faster heart rate, dizziness, anxiety, paranoia, and digestive discomfort.
These uncomfortable reactions are more likely with stronger doses of both THC and HHC. Remember that individual tolerance varies as well.
Can You Overdose on HHC or THC?
Based on what we know about these cannabinoids, a fatal overdose is seriously unlikely. Cannabinoids just don’t affect breathing the way opioids can.
Still, you can definitely take too much HHC or THC and experience very unpleasant and overwhelming effects. Symptoms like paranoia, panic attacks, nausea, vomiting, sweating, confusion, and a racing heart will fade as the body metabolizes these compounds.
To minimize the chance of a bad experience, always start with a low dose and allow plenty of time for effects to kick in. Remember that edibles have a longer onset window, so plan accordingly.
Legal Status of HHC vs THC
Cannabinoid legality in the U.S. isn’t very straightforward. Under the 2018 Farm Bill, the federal government legally defines hemp as cannabis that contains less than 0.3% THC by dry weight (4). It’s treated very differently from marijuana. But individual states also get their own say.
Is HHC Legal in the US?
To the federal government, HHC is a hemp-derived cannabinoid. It can be sold as long as it meets the 0.3% THC threshold.
But just because something is federally compliant doesn’t mean it’s legal in every state. So-called “intoxicating hemp” products are banned or restricted in some states.
Federal vs State Laws on THC
While the federal government restricts cannabinoids derived from marijuana, that’s not the case in every state. Those with legal medical or recreational cannabis markets allow licensed dispensaries to sell products made with delta-9 THC from marijuana.
To be federally compliant, products must be derived from hemp and contain no more than 0.3% THC by dry weight.
Hemp-Derived Cannabinoids and Loopholes
The 2018 Farm Bill legalized hemp, along with its extracts, cannabinoids, and derivatives. But by setting limits on Delta-9 THC alone, it left a gray area for other intoxicating compounds. That’s why manufacturers can make products containing Delta-8 THC, HHC, and other compounds without violating federal law.
Many states have taken steps to close this loophole, so double-check what’s permitted where you live before trying to purchase intoxicating hemp products.
HHC vs THC: Drug Tests & Detection
HHC and THC are quite similar from a chemical perspective. They’re also processed by the body in similar ways, which is a big deal when it comes to drug testing.
Will HHC Show Up on a Drug Test?
HHC can absolutely show up on a drug test. Many drug tests screen for THC metabolites, which are produced as the body processes THC. Similar metabolites are created when HHC is metabolized, and most tests aren’t sophisticated enough to differentiate.
The safest bet? Assume that HHC is just like THC when it comes to drug testing risk.
How Long Does HHC Stay in Your System Compared to THC?
We don’t have a lot of long-term research about HHC, but it appears that HHC is pretty comparable to THC when it comes to its effects in the body. That is to say, the details matter. The precise timeframe for detectable HHC is largely dependent on dose, frequency of use, metabolism, body composition, and the type of test you take.
Occasional consumers may test positive for a few days, while regular users may test positive for a few weeks.
With saliva tests, positive results are possible up to 3 days after your last consumption.
To be safe, assume that HHC won’t clear your system any faster than THC.
Which Is Better — HHC or THC?
One cannabinoid isn’t necessarily better than the other. Deciding between the two really comes down to the experience you want.
THC delivers more intense psychoactive effects, while HHC tends to offer a mellower, more functional experience.
Use Cases: Relaxation, Sleep, Focus, or Fun
If the goal is to relax and unwind, both HHC and THC can do the trick. But THC often creates a heavier experience. HHC is generally described as clearer.
Sedation is a common side effect of THC in high doses, which might be better if you need help drifting off. If you just need to relax before bed, you may prefer HHC. Just know it isn’t known to induce sleep.
Since HHC effects aren’t as intense, some people consider them a good daytime option. Often, HHC lacks the mental fog that can accompany THC.
For recreational purposes, THC is reliably euphoric and mood boosting. But again, choosing between the two is largely a personal preference.
Choosing Based on Tolerance and Experience
Tolerance level has a big influence on how much cannabinoids affect you. If you’re new to cannabis, you might be drawn to HHC because its psychoactive effects are usually milder. More seasoned cannabis consumers may prefer THC for its stronger effects.
For new users, especially, the key is starting with a low dose, regardless of which cannabinoid you choose, and allowing effects to unfold before taking more.
Product Availability and Price Differences
You may be able to find both hemp-derived THC and HHC products locally, but it depends on your state’s laws. Both may also be available online, but shipping restrictions can apply in some states.
Since testing, labeling, and quality standards can vary from one brand to another, third-party lab testing is really important.
