THC Carts: How We Made Our Selection

As a potential buyer, whether you are a seasoned vaper or a newbie, you must take stock of the brands and their products in the market to be in a position to better gauge their effects and efficacy.

It can be a bit tricky at first. But you’ll eventually get there.

You’ll find a brand you can trust. And then, you have nothing to worry about! You can go ahead and blissfully puff away.

We will, of course, tell you all about that in our buying guide. We will also tell you which brands can be trusted as the Best Prefilled THC Cartridges in the current market.

But before that, we will tell you what we did to find our top finalists.

So, shall we…?

We conducted surveys and polls to find out the best and the most popular options in the market. We also asked the participants about their expectations from a brand.

Our experts conducted detailed research on the different practices utilized in creating these masterpieces – right from their farming and extraction processes to their manufacturing and packaging.

We then tried out some of the best options – just to be absolutely sure!

Yes… that’s right. We took every effort to make sure we’ve not missed anything important about the brands or their products – so that you know what to expect as a buyer and a user.

Buying Guidelines For Prefilled THC Vape Carts

With THC carts’ overwhelming popularity in both the online and offline markets, finding a good quality THC oil cartridge has become even more difficult. So, how would you go about picking one for yourself?

Here’s how…


The oil must be derived from organic, GMO-free, and pesticide-free hemp plants. The brand website should provide all that information.

Purity & Quality

Make sure the products you’re buying are safe, pure, and potent. Some brands sell carts with other ingredients. But those ingredients should add to the experience and efficacy, not jeopardize your health. Beware of brands that pack their products with cutting agents, synthetic additives, sweeteners, or artificial chemical flavors.

Method of Extraction

We opt for hemp products that are obtained by safe and eco-friendly extraction methods. They ensure the quality, safety, and potency of the products.


The color of the THC oil matters quite a bit as well. The liquid shouldn’t be opaque or dark in color. Brownish or greenish hues suggest the presence of contaminants. You should look for a clear yellow or light pinkish color in your THC oils.


The THC oil brands we chose are made from natural products with cannabis terpenes and botanical extracts, which don’t contain any synthetic additives or flavors. A customer must check the product label to ensure the product doesn’t contain any cannabinoids or terpenes that shouldn’t be there. For that, they need to do more research on vaping products.

Lab Testing

Brands that submit their products for third-party testing ensure to put only the most potent, pure, and safe products up for sale. Third-party lab reports on a hemp brand website make for an easy selection of products.

Brand Reputation

With so many companies claiming to sell “high-quality” cannabis products, it’s safest to buy from only reputable ones. Check the customer reviews online and make an informed decision.


While buying delta-8 carts, look for options in sizes, potencies, and flavors. Choose what fits your purpose and preferences best – and you’re all set!


Finally, take note of the prices. When it comes to cannabis products, an expensive product doesn’t always make it better. But too cheap a product also raises a red flag. You must get an overall idea about the prices of THC carts in the market before you place your order.

Things To Know About Using Prefilled THC Vape Cartridges

Before you use a THC vape cart, you must be aware of the different types of THC carts available in the market, so you’d know what to expect from a product.

Different Types of THC Carts

Distillate: A highly refined and potent form of cannabis oil, produced from particularly the flowers and extracted using ethanol.

CO2 oil: A concentrated cannabis oil derived by CO2 extraction

Live resin: A terpene-rich extract with pungent flavors or aromas.

Cut oil: An extract with additives or supplement thinning agents, like polyethylene glycol (PEG), vegetable glycerin (VG), medium-chain triglycerides (MCT), or propylene glycol (PG). Oils that don’t contain these agents are called uncut oils.

Terpene-infused: A cannabis extract infused with terpenes to improve flavors and effects.

How To Use THC Prefilled Carts For Best Results?

  • Charge your battery and attach your cartridge to the battery.
  • Press the fire button (as per the product guide on the product) to activate.
  • Start with the lowest setting of the device’s voltage; adjust as per requirement
  • Start with short (1 – 2 seconds) puffs to familiarize your body with the effects.
  • Up the voltage to get a stronger hit, if you’d like.
  • When you sense a change in the flavor, it’s time to move over to a new cartridge.

A Fair Warning: People who’ve used D-8 carts claim that the effects are a bit harsher on the throat and lungs compared to regular THC cartridges. Nevertheless, D-8 works better for your health.

Don’t forget to consult a medical practitioner before you use D-8 THC for medical purposes.

Frequently Asked Questions About THC Cartridges

Q: How long does a single THC cartridge last?

A: This depends on how often you use the cartridge. Usually, a 250mg cartridge can last for around 60 puffs and a 500mg can give you about 120 puffs. But this is just an estimate. The longevity of a cartridge also depends on the thickness of the oil. If the oil is thick, it will last longer.

Q: Can you remove THC oil from its prefilled cartridge? If so, would that be safe?

Yes. The oil can be removed and refilled a couple of times. But it is best to be cautious. It is not safe to tamper with most prefilled cartridges. Remove it only if you’re absolutely sure about the ingredients being safe for removal. It would be wise to consult an industry expert before trying it.

Q: Can I fail a drug test if I use D-8 THC carts?

Yes. Quite possibly. The effects may be subdued or controlled, but the THC metabolites will show up in the first round of test results, which would usually be all your employer needs to see.
