THCV vs THC is a difference of two carbon atoms in the other direction from THCP. THCV, tetrahydrocannabivarin, has a three-carbon side chain where THC has five. It’s a natural cannabinoid that most strains make only in small amounts, and sources describe it as far less intoxicating than THC at ordinary doses. In vapes it’s sold as a ratio with THC, not on its own, and the three we list test between 60.6% and 73.9% THC.
How the two molecules differ
A 2025 review in the medical literature describes THCV as having a ring structure similar to THC’s, with a chain of three carbons where THC has five. Cornbread Hemp makes the same point. CannaMD calls it a naturally occurring analog of THC. The chain is the part of the molecule that grips the CB1 receptor, which is why changing its length changes the effect: a longer chain, as in THCP, binds tighter, and a shorter one behaves differently again.
| THCV | THC | |
|---|---|---|
| Side chain | 3 carbons | 5 carbons |
| In the plant | A minor cannabinoid, at trace levels in most strains | The main cannabinoid |
| Intoxicating? | Much less; at high doses it can produce THC-like effects (Neurogan) | Yes |
| How it’s sold in vapes | As a ratio with THC | As the main ingredient |
What can honestly be said about effects
Less than the marketing suggests. Sellers describe THCV as lighter and more energizing than THC. Healthline is the useful counterweight: THCV is mainly found in cannabis products alongside THC, and once it’s isolated and put into things, it isn’t clear what it does. We don’t make health claims for it, and you should be wary of anyone who does.
The three THCV vapes we list
| Listing | Brand | Size | Tested THC | Price |
|---|---|---|---|---|
| Turn Up, 4:1:1 THC:THCV:CBG, Disposable, 2g | MFused | 2 g | 60.6% | $32.50 |
| THCV Lemon Sunrise Rev Cartridge 1g | Lume Cannabis Co. | 1 g | 63.7% | $9 |
| Wild Berry 5:1 THCV Botanical Terpene Disposable Pen | In House | 0.5 g | 73.9% | $26.25 |
These are state-market cannabis vapes, not hemp products, and all three publish a batch result. MFused’s Turn Up is a 2 g disposable with a 4:1:1 ratio of THC to THCV to CBG. Lume Cannabis Co.’s THCV Lemon Sunrise is a 1 g cart at $9. In House’s Wild Berry is a half-gram pen at a 5:1 ratio.
Notice the THC figures. They’re well below the site median of 85.6%, and that’s the design working, not a weak batch. In a ratio product, THCV and the other cannabinoids take up room in the oil that would otherwise be THC. If you’re choosing between a THCV vape and a standard one, you’re choosing a lower THC dose per puff along with whatever THCV adds.
Which to choose
A standard THC vape if you want the familiar product with the most choice: 1,389 listings here. A THCV ratio vape if you want less THC per puff and are curious about the cannabinoid, knowing the evidence for its effects is thin. For adults 21 and over. Both are part of Weed Pen’s full vape range.
THCV questions
Can THCV still get you high?
On its own it’s described as much less intoxicating than THC, though Neurogan notes high doses can produce THC-like effects. THCV vapes also contain THC, which does.
Is THCV stronger than THC?
No. It’s the less intoxicating of the two. THCP, with a longer side chain, is the one described as stronger.
What is the difference between THCV and THC?
The side chain: three carbons in THCV, five in THC. That changes how the molecule interacts with the CB1 receptor.
Why do THCV vapes test lower in THC?
They’re ratio products. THCV and other cannabinoids such as CBG make up part of the oil, so the THC share is lower: 60.6% to 73.9% on the three we list.
Is THCV natural?
Yes. CannaMD describes it as a naturally occurring analog of THC, found in small amounts in cannabis.
