The cannabis world is evolving fast, and if you’ve been keeping up with the latest trends (like we do here at Red Eye Monkey), you’ve probably heard the buzz around HHC—short for hexahydrocannabinol. It’s often hyped up as a legal, mellow alternative to THC, promising a similar head change without the legal baggage.
You’ll find HHC in everything from vapes to resins, even infused buds that aim to replicate the traditional THC experience. But does it really deliver? And more importantly—how does it actually stack up against THC?
We’ve done the digging, testing, and comparing so you don’t have to. Here’s the lowdown on the most important differences between THC and HHC.
At a molecular level, THC and HHC are close cousins, but not identical twins.
THC, or Delta-9-tetrahydrocannabinol, is the powerhouse compound responsible for the iconic high associated with cannabis. It’s natural, potent, and well-studied. This is the stuff you’re used to if you’ve ever smoked a classic joint or hit a strong edible.
HHC, on the other hand, is a lab-altered derivative. It starts out as THC or CBD and goes through a hydrogenation process—basically, hydrogen atoms are added under heat and pressure, resulting in a more stable molecule. The result? A cannabinoid with a similar vibe to THC, but typically less intense.
So while they share some structural traits, their effects and legal status tell a different story.
Both THC and HHC interact with the endocannabinoid system, locking into CB1 receptors in the brain—the same receptors responsible for everything from mood and memory to appetite and pain perception.
Because of its structure, THC tends to hit harder, bringing on stronger cerebral effects like euphoria, time distortion, and that signature “stoned” feeling. HHC, in comparison, delivers a smoother, subtler ride. The high tends to creep in slower and linger longer, likely due to its enhanced molecular stability and how the body metabolizes it.
From our experience, HHC gives off a more “clear-headed” high. It’s chill, but don’t expect fireworks.
If you’re chasing potency, THC still takes the crown.
Its strong binding to CB1 receptors translates to a more intense psychoactive effect. HHC is more middle-of-the-road—not weak, but not quite as gripping.
But here’s the tricky part: HHC isn’t a one-size-fits-all molecule. The hydrogenation process creates two different types of HHC molecules—one with stronger psychoactive effects, and one much milder. Most products are a mixed bag, and with the current lack of regulation, it’s a gamble which one you’re getting.
We’ve tested multiple HHC products and noticed big swings in potency—even at similar dosages. So if you’re trying it for the first time, start low and go slow.
Anecdotally, and from our own trials, HHC tends to stick around a bit longer than THC. It might not hit as hard up front, but it has some staying power.
That said, everyone’s endocannabinoid system is different. The duration of effects can vary based on how you consume it, your body chemistry, tolerance, and even what you ate that day. But if you’re looking for something that carries a gentle buzz into the evening, HHC may surprise you.
THC is straight from the plant. It’s produced naturally in cannabis trichomes and can be extracted directly from high-THC flower. You’ll find it in traditional buds, oils, and concentrates.
HHC, however, doesn’t exist in significant amounts in the plant. Instead, it’s made by converting THC or CBD in a lab using hydrogenation. That’s right—HHC is essentially synthetic, even if it’s derived from natural cannabinoids.
Making HHC from CBD is a two-step process: first converting CBD to a THC-like compound, and then hydrogenating it into HHC. It’s a bit of a chemical juggling act, and the end product depends heavily on the quality and control of the process.
That lack of consistency is something we’ve noticed in testing. Not all HHC is created equal, and quality control is hit-or-miss right now.
THC has a long list of studied benefits—from pain relief and nausea suppression to appetite stimulation and sleep support. It’s a go-to in the medical cannabis community, and there’s plenty of research backing up its therapeutic effects.
HHC? Not so much. It’s still new to the scene, and there’s very little research confirming its health benefits. It likely works similarly to THC, but any claims about medical use are purely speculative at this point.
So if you’re seeking relief from chronic pain or insomnia, THC is the better-tested option. But remember: quality and source matter more than the cannabinoid alone.
Let’s get real—not all products are safe, especially when it comes to unregulated cannabinoids like HHC.
We’ve come across HHC products with wildly different compositions, and even a few that were suspiciously potent—suggesting they might contain traces of THC despite labeling. On the other hand, poorly made THC products (especially those with super high concentrations) can be too intense or even cause anxiety.
Both HHC and THC can cause:
And in higher doses or for sensitive users, THC especially can lead to paranoia or anxiety.
We’ve also seen reports of HHC-infused edibles causing hospital visits, especially among children who accidentally consumed them. That’s a big concern—especially since labeling isn’t always accurate.
From our perspective, THC has a better safety profile, simply because we understand it better. But regardless of which cannabinoid you choose, only use products that are third-party tested and transparent about their contents.
Now let’s talk legality—because that’s one of the main reasons HHC exploded in popularity in the first place.
Across Europe, HHC operates in a legal gray zone, but things are changing fast. While it was initially sold as a “legal high” alternative to THC, multiple countries have started clamping down on it due to health and safety concerns.
In early 2023, the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) flagged HHC as a substance of concern. Most countries responded by adding it to their controlled substance lists—including Austria, France, Italy, Germany and others.
If you’re in Slovenia, you should know that HHC is now banned.
As of mid-2023, Slovenia classified HHC as a controlled psychoactive substance, making its sale, distribution, and possession illegal. This came after rising reports of unregulated HHC products flooding the market and safety concerns, particularly around edibles that looked like candy or snacks.
So while you might still find websites or vendors trying to sell HHC in Slovenia, it’s important to know: it’s no longer in a legal gray area—it’s straight-up banned.
This crackdown is part of a broader trend in Europe, where governments are acting quickly to regulate synthetic cannabinoids that haven’t gone through proper safety evaluations.
If you’re shopping for alternative cannabinoids in the EU, always check your local laws, because what’s legal today may not be tomorrow. Stick to reliable, tested THC or CBD products when you’re in regulated markets, and be wary of anything labeled “HHC” in places where it’s banned.

What Exactly Is CBD? CBD (short for cannabidiol) is a naturally occurring compound found in the hemp plant. It’s often mentioned alongside THC, but they’re very different. While THC is known for its psychoactive effects (aka the high), CBD doesn’t mess with your head — it’s non-intoxicating and more about balance than buzz. People turn […]
We’ve been exploring the world of CBD for a while now, and one of the most common questions we get is: how long does it actually take for CBD to kick in? Whether you’re taking it for chill, clarity, or a bit of both, timing matters — and we’ve broken it all down from real […]
When it comes to cannabis concentrates, the choices can feel overwhelming. At Red Eye Monkey, we’ve been through the trial and error so you don’t have to. Two heavy hitters in the concentrate game are live resin and distillate, each offering a different kind of experience. After putting both to the test, here’s what we’ve […]
