I finally tried THA! And I’m impressed. Some products are about getting high. Others are about getting quiet. This does both quite nicely.

If you’re someone whose brain runs at approximately 1,000 thoughts per minute (hi, hello, welcome to my personal nightmare), you know the feeling. The day ends, the lights dim, and instead of relaxing, your brain decides it’s the perfect time to replay every conversation you’ve had since 2007.
That’s exactly why Gravity by Knockout caught my attention. In this Knockout Gravity THA H4CBH review, I wanted to see whether this nighttime blend actually delivers on its promise: a clear head, a heavy body high, and the kind of relaxation that lets your brain finally slow down.
And…yeah. For the first time in a while, my thoughts slowed down from 1,000 running tabs to just one—and that one thought was simply: “Wow, this movie is ridiculous.”
(For the record, the movie was Bullet Train. If you’ve seen it, you know exactly what I mean. If you haven’t—trust me, it’s gloriously chaotic and somehow even better if you’ve read the book.)
And Gravity turned out to be the perfect companion for that cozy kind of night.

Knockout Gravity THA H4CBH Review: First Impressions
Right from the first inhale, the thing that struck me most was how smooth the liquid is. It’s easy to smoke with a gentle, clean inhale with a subtle flavor profile.
Knockout describes the terpene blend as Deep Berry, and that’s pretty accurate—but don’t expect candy sweetness. The berry note is light and layered under a woody, natural taste that reminds me much more of the real thing than overly artificial flavoring.
It’s one of my favorite terpene profiles I’ve tried from Knockout so far because it balances sweetness with authenticity.
The Effects: A Two-Stage Experience
Knockout describes Gravity as a two-stage process, and it really is.
Stage One: Head High Clarity
Within seconds of the first puff, I noticed a warm sensation spreading through my chest. This stood out immediately because it was different from the usual behind the eyes sensation that typically comes on first. Not overwhelming, just that comfortable “ahhh” feeling that signals the beginning of relaxation.
Soon after, a light buzz appeared behind the eyes (there it is!). The brain was still alert, but softened. Fuzzy in a happy, comfortable way. And this is where Gravity really shined for me. Instead of amplifying thoughts (something certain cannabinoids can absolutely do), it did the opposite.
My mind quieted down. No racing thoughts. No mental pinball machine. Just one simple stream of consciousness. Which made ending the day and watching a movie feel weirdly immersive in the best way.
Stage Two: The Body High
After about 30–40 minutes, the second stage started to take over. And that was also when the product name Gravity suddenly made perfect sense.
Your body begins to melt into whatever surface you’re sitting on. Sofa. Bed. Chair. Doesn’t matter. Everything becomes extremely comfortable, and your eyelids may begin to operate at approximately half-mast.
Hot tip: If someone sees you looking suspiciously relaxed: Blame allergies. Works every time.
Hotter tip: Save this for when you’re home relaxing and totally comfortable. Not when you have to be out and about blaming allergies at all.
The Munchies Situation
At around the 90-minute mark, something else arrived, the munchies! And not the polite kind. More like “feral raccoon rummaging through the kitchen” level hunger. So plan snacks accordingly.
Trust me on this one.
Duration
The main experience lasted around three hours before transitioning into a very comfortable sleep. But what impressed me most was the next morning. No brain fog. No grogginess. Just a lingering body relaxation and a very clear head. That’s something I always appreciate in a nighttime product.
What’s Inside Gravity?
Gravity is built around a combination of cannabinoids designed to create a balanced evening experience.
THA – contributes to the uplifting head effects that start the experience.
H4CBH – responsible for the heavier body relaxation that follows.
CBD / CBG / CRD – supportive cannabinoids that help keep the overall experience smooth and grounded.
The result is a blend that begins with mental clarity before gradually settling into deep physical relaxation.
Who This Product Is Best For
Gravity feels tailor-made for people who want to decompress at the end of the day.
It’s especially good if you:
• Have a busy brain that struggles to shut off
• Enjoy movie nights or music sessions
• Prefer body relaxation without mental chaos
• Want something clearly designed for evening use
If you’re more of a daytime, energetic experience person, Knockout has other options like RAZOR or THA Real that lean more toward the sativa side (though I haven’t tried them yet!).
But for indica lovers? Gravity is a treat.
The Price / Where to Buy
It’s not the cheapest at ¥16,000, so like I said, this is for those really cozy nights. And for something that I think hits even better than therapy and a massage, I’d say it’s worth it.

You might also find it at select CBD/Altnoid stores like CBD Hills in Tokyo and Cannabis Club in Osaka.
Final Thoughts
I review a lot of Knockout products, and I’ll admit I hand out plenty of high scores, but Gravity genuinely stood out. It did something simple and rare: it helped my brain slow down.
For anyone who ends their day feeling mentally overloaded, that quiet moment where everything finally softens is incredibly valuable. Gravity delivered exactly that.
A clear mind. A deeply relaxed body. And one extremely enjoyable movie night. That’s a pretty perfect evening.
