Jack Herer was the strain behind half the cannabis cup wins of the early 2000s, and this 1-gram disposable from United Strains of America puts that legacy in your pocket. Pressed as solventless live rosin and lab-tested at 89.65% THCa with 17.30% CBD, it leads with crisp citrus and pine on the inhale, then surfaces a soft diesel undertone on the exhale.
The effects open with the clear-headed lift this strain made its name on: focused energy, easy creative flow, and a positive mood that holds steady through the afternoon. The 17.30% CBD smooths the experience without dulling the head buzz, which keeps the high productive rather than scattered. If you're trying to get things done or carry a good conversation, this is a natural fit.
The device runs on a single button. Press the button 5 times to turn it on or off, then press and hold while inhaling to draw. The rosin inside is solventless, pressed from fresh-frozen flower with only heat and weight, so there's no distillate and no added flavoring at any stage. A USB-C port keeps the battery firing through the last of the gram.
What is THCa, and Will This Jack Herer THCa Vape Get You High?
THCa is the raw form of THC that cannabis produces before any heat touches it, and on its own it won't get you high. The change happens when you take a pull: the coil heats the rosin and converts the THCa into active THC on the spot, so the high lands immediately. The CBD in the formula runs alongside that high without canceling it, which is part of why this vape feels focused and calm instead of racy.

Frequently Asked Questions
How Do I Use My Jack Herer Live Rosin THCa Vape?
Press the button 5 times to turn the device on or off. Press and hold the button while inhaling to use. A short two to three second draw is enough to start, and it's worth waiting a few minutes before going again, especially at this potency level.
What Does the CBD Do in This Vape?
The 17.3% CBD runs in the background of the high rather than blocking it. CBD tends to take the edge off sativas that push a little too hard, which is why Jack Herer in this format reads as clear-headed and focused instead of jittery. The lift is still very much there, just smoother.
Why Does Jack Herer Have Such a Loyal Following?
It's one of the few sativas that reliably delivers energy without the anxiety. The terpene mix here, terpineol alongside myrcene and pinene, creates a head feel that's alert and creative but grounded. Live rosin preserves that profile fully, so you get the strain's true character rather than a flavored approximation.
How Many Draws Does a 1G Device Hold?
Expect somewhere between 200 and 300 pulls from a gram of rosin, depending on how long each draw runs. For a moderate user taking a few hits per session, that works out to roughly 60 to 100 sessions before the device runs out.
Is This Vape Reusable?
No, it's disposable. The battery recharges through the USB-C port, but only so the device keeps firing until the rosin is finished. Once the gram is used up, the vape has done its job and should be discarded properly.
Is It Legal, and Can You Ship It to My State?
In most cases, yes. The vape qualifies as a hemp product under the 2018 Farm Bill because it contains less than 0.3% delta-9 THC, making it legal federally. State laws are where things get uneven, since a small group of states have written specific rules covering THCa vapes, so a quick check on your state's stance before ordering is the safest move. Everything ships in plain, unmarked packaging.
