How We Selected THC Carts For This Review

You should always ensure the quality of every product and its value for money before buying it. Whether you are a seasoned vapor or a novice, you need to assess brands for their efficacy, given that there are so many bogus brands in the market.

Only high-quality brands offer you a blissful vaping experience. Eventually, we will tell you how to pick the right one in our buying guide. But before that, let us tell you how we finalized our list.

Here are the factors we considered:

  • The results of several polls and surveys about the popular vape carts on the market
  • Production strategies of the brands while producing pure Delta-8 THC, like farming and extracting processes as well as their manufacturing and packaging.
  • The customer service offered by the brand
  • Feedback by genuine consumers on social media forums such as Reddit and Facebook.
  • Our own experience after trying the most popular options

We were extra cautious while finalizing our list to ensure that we recommended only the best ones. We also made sure that we did not miss any detail about the brands and their products, so you know what to expect as a buyer.

After meticulous research, we have narrowed it down to these finest five brands that met all our criteria and are sure to offer you an excellent vaping experience. Let us discuss them in detail.

Things To Consider While Buying THC Oil Cartridges:

Delta-8 THC is an isomer of Delta-9 THC. It resembles its cousin in many respects, including its effects, structure, and reaction to numerous other chemicals. However, it has fewer and milder side effects than the latter. So much so, its intensity of euphoria is much weaker, making it a safer option than Delta-9 THC.

Like most other cannabinoids, the quickest way to experience the effects of Delta-8 THC is by vaping, and nothing’s better than THC cartridges that can be disposed of after.

Vaping offers the most potent and almost instant effects. Moreover, vaping is certainly preferred over smoking, as the latter involves the direct burning of plant material and the emission of harmful gases.

There are tons of brands selling D-8 THC products in the hemp market. If you are considering giving D-8 THC cartridges a try, you may want to know how best to judge a product – and its brand – so that you don’t end up with a lousy product. It may not only be less potent but, in the worst-case scenario, be detrimental to your health.

So, here are some of the factors you should consider before placing your order:..


Quality is the most important factor when it comes to D-8 THC products. You must opt for brands that use the best strains of US-grown hemp to extract their D-8 THC. These products should be obtained using a safe and eco-friendly extraction method like the CO2 technique. The best way to assess the quality of a product is by checking the lab reports for purity, efficacy, safety, and potency.


You must ensure that the products you are procuring are clean, safe, and potent. The THC vape juice should be sourced only from all-natural, organic, and non-GMO hemp plants grown without any pesticides or chemicals. You must check that the vape juice contains only Delta-8, without additives, sweeteners, cutting agents, or high levels of Delta-9 THC.


You must opt for a brand that makes THC oil from naturally derived extracts, terpenes, and botanical extracts. At the same time, you must ensure that the brand does not use any synthetic additives, flavors, or chemicals. Also, check for product labels to see if there are no unwanted cannabinoids or allergens.

Lab Testing

Third-party labs thoroughly assess products for their quality, safety, and potency. The brands that get their products tested by these labs and display their results online are certainly more trustworthy than the brands that refrain from doing so.

Brand Reputation

With several companies claiming to sell high-quality hemp products, you should always choose to buy products from reputable ones, given that so many fake brands dominate the market. Brand reputation is directly reflected in customer reviews and ratings. So, ensure that you check them before placing your order.


The color of your THC vape oil matters a lot. Ideally, your THC oil should be clear yellow or light pinkish, which indicates good quality. You must avoid brownish or greenish oil, too. These colors suggest the presence of contaminants. Also, don’t opt for dark or opaque oil.


The carts that we have recommended are compatible with 510-threaded batteries.


D-8 THC carts are available in several sizes, potencies, and a wide range of flavors. You can choose your vape cart depending on your preferences.


You will find D-8 THC cartridges contain different forms of D-8 THC, as listed below. You can opt for the type depending on your preference for pure oil or the one with preferred fillers.

Distillate: This contains the most refined and potent form of cannabis oil, extracted from hemp flowers with the help of alcohol.

C02 oil: A concentrate extracted using the CO2 extraction technique

Live resin: THC extract, rich in terpenes, with intense flavors and aromas

Cut oil: An extract containing additives/carrier bases, like polyethylene glycol (PEG), medium-chain triglycerides (MCT), propylene glycol (PG), or vegetable glycerin (VG).

Terpene-infused vape oils: An extract that is blended with terpenes for additional flavors and effects.


Lastly, do take note of the prices. Cheap products should raise a red flag. Extracting pure Delta-8 THC is not an easy task. It is present in trace quantities in cannabis plants. So, it must be converted from CBD for commercial viability.

That being said, an expensive product doesn’t always assure quality. So, you must do overall research of the brands you’re planning to buy from and get a general idea about the range of prices of THC carts in the market and then opt for the best one.

Buying Guide For Beginners: How To Use THC Vape Cartridges?

Delta-8 THC carts are pretty easy to use, but these guidelines will help you understand how to operate a cartridge better, especially if you are a novice.

  • Make sure that your battery is fully charged before attaching it to the cartridge.
  • With some vaping devices, you’d have to press the “Fire” or “Power” button to produce the vapor, while others are draw-activated.
  • Start from the lowest setting of the device’s voltage at first. You can adjust it according to your requirements.
  • Always begin with short one-to-two-second puffs to gauge the product’s potency and familiarize your body with the effects. 
  • You can always increase the voltage gradually to get a stronger hit.
  • Once you sense a change in flavor, you should move over to the new cartridge.

Precautions While Using THC Vape Carts

Delta-8 carts tend to be slightly more harsh on your throat than CBD. But their benefits far surpass their downsides.

Nevertheless, you should consult a health practitioner before trying D-8 THC for any medical condition or even otherwise, as it could interfere with other medications and supplements.

Do not use these carts if you are pregnant or below 21 (18 in some states).

Also, remember not to drive or operate any machinery if you have just used D-8 THC. It could hamper your motor skills and judgment to a certain extent.

A high is high – no matter how weak. People react differently to cannabinoids.

THC Cartridges FAQs

Q: How long does a single THC vape cartridge last?

A: This depends on the frequency of usage. Generally, a 250mg cartridge may last for about 60 puffs, while a 500mg cart can give you around 120 draws. However, these numbers are just an estimation. The thickness of the oil also determines the duration for which a vape cart lasts. Thicker oil tends to last longer. Besides, individual lung capacity and draw length also affect the consumption rate.

Q: Can you refill THC oil into a prefilled cartridge? If so, is it safe?

  1. Yes. You can remove the lid and refill the cart with fresh oil a couple of times – but better be cautious. It’s actually advisable not to tamper with most prefilled cartridges. It is better to consult an industry expert and ensure if the ingredients are safe for removal and then try it.

Q: Will I fail a drug test after using D-8 THC carts?

  1. Yes, it’s entirely possible you’d fail a drug test just after consuming Delta-8 or if you’re a regular consumer. Even if the effects of D-8 THC are milder or weaker than Delta-9, the D-8 THC metabolites resemble those of D-9 THC. These THC metabolites can show up on the drug test results, making you test positive for THC.

Q: Do THC vape cartridges and edibles have the same effect?

  1. Delta-8 THC vapes and edibles hit your body differently. Vape carts are the ultimate way to experience the effects of D-8 THC and ensure a quicker onset of effects. However, these effects wear off relatively faster than edibles. We suggest that you start with one to two gummies, or even three for a stronger body high if you are an experienced Delta-8 user. But remember that edibles take more time to take effect compared to vapes.

Q: When is it advisable to take Delta-8 THC, daytime or nighttime?

  1. When taken at lower doses, D-8 THC may increase your focus, enhance your mood, and fuel creativity during the day. Higher doses of Delta-8 may assist with calmness, relaxation, and better sleep.

Q. Why prefer a prefilled THC cartridge?

  1. Prefilled THC carts offer you several benefits. First, they help with dosing. Concentrates are very strong, and you should be mindful of the quantity you are taking. With carts, you don’t need to worry about that, as these devices have a timer that prevents you from consuming THC in excess amounts.

Second, they are incredibly portable and can be easily slipped into a pocket or a backpack.

Third, they offer a potent, safe, and discreet way of enjoying THC, along with getting you instant effects.

Final Thoughts: What Is the Best THC Cartridge?

Delta-8 THC offers you many health benefits besides providing a gentle euphoria. These carts can help you enjoy a discreet cannabis experience without the smoke, odor, or any side effects.

Several companies claim to offer high-quality prefilled THC oil cartridges, although not all of them are up to the mark regarding the quality and effectiveness of their products. Once you find a brand you can trust, you can enjoy cannabis in every positive way possible.

Delta-8 THC carts are available in all types of delicious and mouth-watering flavors. They can offer you calmness and relaxation. However, you must consider the legal status of D-8 in your state of residence and, definitely, consult your doctor before using any cannabis product for a medical condition – or even otherwise.

In this article, we have discussed some of the best-quality, lab-tested THC vape carts. 

However, we would strongly recommend you to either go for Exhale or Budpop. Since they are 100% organic and all-natural with no artificial flavors or colors. Even if you choose to buy some other product, you must bear our warnings and guidance in mind. They will keep you safe and healthy.
