THC-O Vape Carts

Want to try out THC-O? For those willing to take a walk on the wild side, this is the perfect vape cartridge for you. Although there’s a lot of buzz around THC-O, it’s not a cannabinoid to be taken lightly. Being referred to as ‘Delta 8 on steroids’, we believe THC-O by itself, is too strong and might give users a bad experience (rapid heart rate, chest pain, etc). Our team has tested various profiles and this is the formulation we recommend for an enjoyable experience.  As THC-O packs quite the punch, we recommend you start low and slow with this one.  For the more adventurous, we also have THC-O + Delta-10 Carts or THC-O+Delta-8 Carts.

  • Ingredients: THC-O distillate, natural terpenes
  • Average THC-O: ~850mg
  • Average minor cannabinoids & terpenes: ~100mg
  • no VG, PG, PEG, Vitamin E, MCT, or any other cutting agent

One and done

Gets to where I want to be. Asleep fast in bed.

A lot of hype, I prefer the delta 8 for the rush of high, thc-o will not give.

A lot of hype, but it feels good. Its a lot like being high the hour after smoking a joint. I prefer the delta 8 for the rush of high- the thc-o will not give the same rush.

Thc-O acetate

Good stuff! Sometimes the Deltas need a little boost...add the O. Denex has great prices, fast shipping and is my go-to online source.

Pretty fire

Very strong, smooth carts. High lasts a pretty long time but takes a bit to come on. One of my carts was leaking though and kind of fell apart but i put it into another one so it was fine. Other than that these were pretty good.

Love these carts. THCO is my new favorite.

Our customer safety and experience are of the utmost importance to us. And so, for the best possible performance and taste, our THC-O vape cartridge features high-quality:

  • glass housing
  • ceramic core
  • ceramic mouthpiece
  • 510 thread batteries compatible cartridges
  • Battery voltage/capacity: 2.5V to 3.5V

Note: Some batteries have a warm-up function for optimal performance, typically activated with two clicks.

Full Content: 1.1 mL

The top of the vape cartridge is supposed to have air. When the cartridge is made, the oil is poured onto the top of the glass tank and quickly capped to prevent leakage. This can be as much as 20% of the total amount. This makes the cartridges look partially empty while actually containing an unlimited amount of product.

Due to its high purity and concentration, this product can be harsh to those that are not used to vaping concentrated products.  We recommend taking a short and easy puff (1 second) to enjoy a smoother experience.

This product can be intoxicating to some people. DO NOT DRIVE OR OPERATE ANY MACHINERY WHILE USING THIS PRODUCT. 

What is THC-O Acetate (aka Delta-8 THC-O-A) and its effects?

THC-O Acetate is a new hemp-derived cannabinoid that takes Delta-8 THC and makes it more bio-available through a process called acetylation (Aspirin uses the same process). This new derivative can be considered to be much more potent than Delta-8 and can last longer. We recommend starting with a small amount first.

  • THC-O has uplifting & pleasant effects.

  • THC-O gives you a smoother experience without the harshness.

  • THC-O has up to 5 times stronger than delta-8 but might take longer to feel.

  • THC-O has less viscous which is just perfect for vaping... no more clogging!!

More research is required to scientifically prove the medicinal and therapeutic effects of THC-O. Most of the information on this compound's benefits is mostly anecdotal. Some THC-O users report that it helps with:

  • pain relief

  • lessen stress

  • increase appetite

  • Others use it for its sleep-inducing properties, despite its potency.

Troubleshooting THC-O Vape Cartridge Issues

  • If your vape battery has a warm-up function, use it. Usually, only two clicks are required.

  • To avoid leaking or clogging, keep it away from extreme heat or cold.

  • Warm up the cartridge with a hair dryer before flipping it upside down.

  • Gently blow into the mouthpiece or use a small and pointy object like a sewing needle or safety pin to easily get into the mouthpiece holes in the hopes that the clog is near the top.

If it does leak, try the following:

  • Do not keep the activated button pressed for too long. Do a short, easy puff.

  • Reduce the voltage of the battery or increase the ohm. This can make things go more smoothly.

  • When you're done, put the cartridge back upright.

Will THC-O make you fail a drug test?

We lack sufficient data to make a definitive statement, but THC-O may appear on many drug tests looking for Delta-9 THC substances. You should bypass using this product if you need to undergo a drug test, as THC-O will almost certainly cause you to fail one.
