If you want to vape THC-O without the hassles of tank devices or even cartridges, disposable pens are perfect. Designed with maximum convenience in mind, disposables allow you to seamlessly enjoy the hard-hitting effects of THC-O.
Recreational users are going wild for THC-O products, which may be triple the strength of regular cannabis. But with THC-O still so new and so much varying information flying around, the substance is often misunderstood.
I’ll cover all you need to know about THC-O in this review, starting with my top five THC-O disposable vape pens of 2022!
Top 5 Begin Here
1. Best Selling THC-O Disposable

ELYXR LA – THC-O Disposable (1000mg)
ELYXR LA stocks several THC-O and other psychoactive hemp-based products, but these THC-O disposables are a stand-out in their collection. Infused with premium, intense THC-O oil and plant-derived terpenes, these pens get you stoned in the tastiest way possible.
Expect more potent and long-lasting effects from ELYXR LA’s THC-O disposables than their delta-8 and delta-10 offerings. The pens have a stylish, cylindrical design with the ELYXR logo printed on the front.

Binoid – THC-O Rechargeable Disposable Vape
An ever-present in my THC-O product reviews, Binoid comes in third place with these rechargeable disposable vapes. The 92% THC-O distillate brings out the best of the cannabinoid’s super-potent effects, while the 8% terpenes provide complementing flavor.
These hemp-based pens offer an efficient and convenient THC-O experience. The sleek black-cased device fits nicely in the hand and generates smooth, clean vapor.
The built-in vape battery comes fully charged, although it’s handy that you can recharge if required. While there’s no specific lab report for this product, the THC-O used by Binoid has passed the Food & Environment Safety Analytical Lab’s third-party checks.
Strains: Blue Zkittlez (Indica – Tranquil), Do Si Dos (Indica – Smoothe), Maui Wowie (Sativa – Adventure), White Runtz (Hybrid – Inspire)

3Chi – THC-O Disposable Vape
You’re guaranteed a high-quality THC-O experience when vaping a 3Chi disposable. A leader in the hemp-based legal high market, 3Chi uses CCELL disposable devices for pure vapor and smooth hits, and they never add cutting agents.
These THC-O Disposables contain 95% THC-O extract and 5% cannabis-derived terpenes, ensuring authentic flavor and effects. The broad-spectrum THC-O oil does not have any detectable THC, as confirmed by the third-party lab report from Avazyme.
3Chi does warn that THC-O e-liquids can be harshness on the throat, although this isn’t a problem specific to them. Get the most out of these disposables by taking short puffs rather than long hits.
Strains: Blue Dream (CDT), Melonatta (CDT)
4. Runner Up

Delta Extrax – Premium THC-O Disposable
Delta Extrax (aka Delta Effex) has come up with four punchy 2-gram THC-O disposables, with a pair of hybrids and indicas in their selection. These THC-O pens contain hefty amounts of THC-O and delta-8 distillate – the latter produces an energizing effect.
The enriched THC-O e-liquid also consists of plant-derived terpenes, taken from world-famous strains like Grape Ape and Girl Scout Cookies. Delta Extrax does not use cutting agents or dilutants.
These single-use, rechargeable pens have a 280mAh battery and a USB-C charging port, although Delta Extrax doesn’t include a charger. Start with one or two puffs and increase your dose as needed. Third-party tested with less than 0.3% THC.
Strains: Berry Gelato (Indica), Grape Ape (Indica), Double Bubble OG (Hybrid), GSC (Hybrid)
5. Runner Up

Denex Hemp Co – THC-O Disposable Vape
These THC-O Disposable Vapes from Denex Hemp Co have roughly 85% (850mg) THC-O extract and 5% (50mg) natural terpenes. While that makes them a little less potent than some THC-O disposables featured here, they are still solid pens.
Denex has an all-natural philosophy, shunning pesticides and herbicides during hemp cultivation and refusing to add cutting or thinning agents to their vape juice. These 1ml pens have a pure mix of hemp-derived cannabinoids and terpenes.
You can recharge Denex’s THC-O Disposables using a micro-USB-B charger, but you’ll need to buy one separately. Unfortunately, Denex has not yet supplied a relevant third-party lab report for these disposables, despite their other products having them.
Strains: Tangie (Sativa), Blueberry AK (Indica), Granddaddy Purple (Indica)
What are THC O Disposable Vape Pens?
THC-O disposables are single-use vape pens loaded with e-liquid rich in THC-O distillate extract. These one-piece devices make vaping THC-O even easier than cartridges, as the battery comes pre-installed and fully charged.
The efficiency and simplicity offered by disposables come at a slightly higher price tag, but it’s a small cost to pay. If you want to keep your THC-O levels topped up while on the move and don’t have the desire or patience for maintenance, disposables have your back.
High-quality THC-O disposables should have as few ingredients as possible. THC-O distillate and cannabis-derived terpenes are all you need in 1 or 2ml vape pens. Steer clear of companies that use cutting agents or dilutants, such as PG, VG, and MCT oil.
THC-O disposable vape pens come in multiple varieties, with many taking the names of renowned marijuana strains. All disposables fit into one of three categories: sativas, indicas, and hybrids. We’ll discuss each product type in more depth later.
What is THC O?

THC-O (THC acetate ester) is an intoxicating cannabinoid with three times the psychoactive potency of typical THC. In the expanding market for hemp-based recreational drugs, THC-O has emerged as the cannabinoid of choice for many hardcore, veteran users.
Like traditional THC cannabinoids, THC-O makes you stoned by connecting with the endocannabinoid system’s (ECS) CB1 receptor. However, it appears that THC-O has a higher binding affinity than THC and that it stays effective at the receptor for longer.
THC-O has a mysterious and somewhat dark history, being initially used as an incapacitating agent during the Edgewood Arsenal experiments. That said, we also know the CIA unsuccessfully trialed THC as a truth serum during Project MKUltra!
But since those clandestine days, THC-O has re-appeared as an exciting and legal recreational substance. Notably, unlike many hemp-based highs available right now, THC-O is not naturally occurring – it’s created by synthesizing THC or delta-8 extract.
How to use THC O disposable vape pens
There’s a fine line between a euphoric, psychedelic-like THC-O high and a bad trip riddled with anxiety and paranoia. THC-O’s intensely intoxicating properties leave little margin for error, so you must use disposable vape pens cautiously and responsibly.
In contrast to other cannabinoids, even vaporized THC-O has a delayed onset of effects. While waiting for your high to kick in, resist the temptation to top up your dose too quickly – you might regret it later!
Most brands advocate taking one or two puffs and then waiting for 30 minutes. That’s sensible advice for first-timers, although seasoned users may feel comfortable taking a few extra draws.
But whatever dose you decide on, hold off for at least half an hour before consuming more. Staggering your doses allows you to indulge in THC-O without going overboard. If you’re in for a long session, top-up every 30 to 60 minutes.
On occasions, the psychoactive effects of THC-O may be more than you anticipated – it’s easy to underestimate the intensity of vaping. Thankfully, you can manage the adverse consequences of too much THC-O with some humble, non-intoxicating CBD.
THC-O and CBD couldn’t be more different, hence why the latter helps neutralize the effects of the former. As with THC, the CBD cannabinoids temper THC-O’s psychoactive properties by reducing activity at CB1 receptors as an antagonist.
Get the most benefit from CBD by smoking a joint, vaping a cartridge, or taking a tincture. When you require instant relief from a bad trip, these fast-acting products serve you much better than edibles, syrups, and capsules.
The legal status of THC O tinctures

THC-O tinctures are federally legal in the United States as hemp-derived products, but they must have less than 0.3% THC. The cannabinoid became legal in 2018 after the Farm Bill was written into law. However, not everybody accepts that THC-O should be legal.
Critics argue that THC-O is technically an analog of THC and therefore prohibited under the Federal Analog Act, which became effective in 1986. But there’s a small yet crucial difference between regular THC-O and the THC-O found in hemp-based products.
While delta-9-THC-O is indeed a THC analog, delta-8-THC-O is not. And it’s the latter that we see in hemp-derived THC-O tinctures. Since delta-8 is a legal substance under the Farm Bill, there’s no way that an analog of delta-8 could be covered by the Federal Analog Act.
THC O vs. other cannabinoids
THC-O vs. delta-9: Delta-9 refers to THC in a legal, hemp-derived form. These products induce a classic cannabis high, which I’d recommend over THC-O for those new to the psychoactive experience. But if you want explosive highs, THC-O beats delta-9 hands down.
THC-O vs. delta-8: The energizing and fatigue-busting properties of delta-8 make it an ideal hemp-based high during the day. However, with effects even milder than THC, it won’t give you the intense psychoactive trip that THC-O can.
THC-O vs. HHC: Renowned for its sedating and intoxicating qualities, HHC is a perfect cannabinoid to relax with at the end of the day. But like delta-8, it’s also less potent than THC, so falls short of THC-O if you’re looking for mind-blowing highs.
What to Look for When Buying THC O Disposable Vape Pens
Most THC-O disposable vape pens are similar, although there are some differences to be aware of. These tips should help you find suitable and authentic THC-O pens.
Third-party certificates of analysis (COA)

Third-party testing should be your first consideration when shopping for THC-O disposables. Independent product verification gives you guarantees on the potency of the e-liquid used, whether it’s legal, and if it contains any harmful impurities.
Companies typically publish COAs on the product page or as part of a list of lab reports on a separate page. Make sure the analysis matches up with the THC-O disposable you’re considering, and check the date, too – the best brands update their COAs every few months.
Terpenes
Sativas: THC-O pens made with sativa terpenes initiate a more energizing, cerebral, and uplifting high than other pens. Because of the stimulating effects, I prefer using these strains in the mornings or early afternoons.
Indicas: Quite the opposite, indica THC-O pens drop you into a relaxing high, soothing your muscles and dissolving any mental stress. These strains are perfect for chilling out in the evenings or for helping you sleep.
Hybrids: Enjoy a blend of indica and sativa effects with a hybrid THC-O disposable. The balance of stimulation and sedation makes these strains perfect at any hour of the day.
How to Store Your THC O Disposable Vape Pens

Store THC-O disposable pens in a lukewarm and dark place, such as a cupboard or drawer. Do not expose your disposables to direct sunlight and keep them away from children.
How Long do THC O Disposable Vape Pens Last?
THC-O disposables can make you high for up to six hours, which is twice as long as other cannabinoids. Regular THC-O users may find the effects wear off sooner due to tolerance.
Purchasing THC O Disposable Vape Pens Online vs. Shops Near Me

If you are ready to make your first THC-O disposable purchase, I recommend shopping at specialist stores and shunning the likes of headshops and gas stations. The safest and most convenient place to buy THC-O products is online.
With the hemp market unregulated, it makes sense to stick with experienced vendors who can easily sniff out scammers. When buying from a trusted online store that prioritizes third-party testing, you know you’re getting top-shelf THC-O.
