Best Delta-8 Carts[Reviews]: Can’t Get Any Better!

#1. Diamond CBD’s Delta-8 Vape Oil Carts – 900 mg

Diamond CBD’s 10X and Chill Plus Delta-8 product lines are probably the best THC vape cartridges there are in the market.

They are amazing in almost every way. They come in a wide variety of flavors, contain pure and concentrated delta-8 THC, and are made from hemp extracts organically sourced from right here in the US.

Apart from delta-8 THC, the 10X carts contain a wonderful blend of hemp-derived terpenes and herbal extracts that only go to add to their therapeutic value and flavor. As for the Chill Plus range of carts, they come in exactly the same flavors and contain as much CBD as delta-8 THC, i.e., 900mg.

Extracted from different variants of Indica and Sativa strains, these cartridges contain a blissful mix of 11 amazing flavors, thanks to the brand’s famous concoctions of different cannabis strains.

Each of these variants – Guava, Grape Ape, Strawberry Lemonade, Apple Fritter, Mango Kush, Banana Kush, Lemon Squeeze, Tangie OG, Sour Diesel, Pineapple Express, Blue Dream – contain varying combinations of THC, natural hemp-derived terpenes, and other botanical extracts.

These products are all organically sourced, CO2-extracted, and lab-tested, and contain no synthetic additives, except hemp-derived plant nutrients.

All of these products contain less than 0.3% delta-9 THC, making them both legal and safe. These carts pack the right amount of high to get you floating in the clouds, but not too much to make you experience the nasty side effects to generally associate with THC.

  2. Ensures value for money for the customers
  3. Third-party lab tested; results available on the product page
  4. 11 flavors available in both lines of vape carts, i.e., Chill Plus and 10X Delta-8 Vape Carts
  5. Organic and eco-friendly brand


  1. Not all products are made with full-spectrum extracts

Diamond CBD has drawn a whole lot of positive reviews from users in general. Users not only enjoyed shopping with them but also loved the products. They loved their taste, the natural high they gave, and how calm and relaxed they felt after using these carts.

Most customers said that they felt it was almost like smoking weed without any of its side effects.

Except for the typical issues with the compound, like short-duration effects and building tolerance to the compound (which are common among all D-8 products), customers were generally happy with Diamon CBD’s D-8 carts.


The brand hosts a blog, which is frequently updated, to explain everything a user needs to know about the industry.

It is easy to get in touch with their customer support team via email or over a phone call.

You can easily return an unopened product for a replacement or refund within 30 days of purchase. However, exchanges are only applicable to defective or damaged products.

The Best Part: The brand’s core team comprises a big team of doctors, chemists, and scientists, who are continually striving to develop some of the finest, purest, and most refined products in the hemp market.

#2. 3Chi’s Delta-8 THC Vape Cartridges

One of the pioneering brands to introduce delta-8 products in the cannabis market, 3Chi is an all-American brand, founded by a biochemist with over 15 years’ experience in different hemp-based formulations.

Since 2019, when it developed the best method of extracting pure delta-8 THC from hemp, the brand has been making and selling America’s first legal THC-based products.

The brand aims at creating high-quality cannabinoid products to promote human health and wellness. Its products are manufactured from lab-tested extracts that are pure and highly concentrated.

Each of the brand’s vape carts are housed in a CCELL glass-body with a ceramic core. Available in 2 sizes, i.e., 1ml and 0.5ml, they contain over 95% pure delta-8 THC extracts. While the 1ml variant contains 950mg THC, the 0.5ml version has 475mg THC.

Apart from THC, the only other ingredient these carts contain are botanical/cannabis-derived terpenes (50mg/25mg). You won’t find any VG, PG, PEG, MCT, or even Vitamin E in these products.

With this product, what you see is what you get. Period.

Each of these cartridges contains cannabis extracts of varying proportions of Sativa and Indica hybrids. The brand offers 25 variations in strains (and flavors), 13 of which contain cannabis-derived terpenes. As for the remaining 12 options, the terpenes are obtained from other natural botanical sources.

Containing less than 0.3% delta-9 THC, these products are safe, effective, and promote a variety of positive moods.

Having garnered over 1,000 positive reviews, this brand has always succeeded in keeping its consumers satisfied and happy.


  1. High-quality, well-researched products with natural cannabis-derived extracts
  2. 95% pure, concentrated, and highly potent THC vape carts available, with nothing more than natural terpenes
  3. A good high with no side effects
  4. Lab-test results available on the brand website


  1. Currently, there is no way to call or send an email to the company. Only a contact form is available for customers to reach out to the company to address non-shipping-related issues or for shipping-related queries on orders that are older than 28 days.
  2. Effects are a little too harsh on the throat. Puffs need to be not more than a second long.
  3. The effects seem to wear off sooner than the Diamond CBD products.


Customers loved the uplifting experience of 3Chi’s delta-8 carts.

They were pretty much satisfied with the brand’s shipping and return policies. Given the number of happy customers, the CONS we just mentioned would seem mundane and useless.

As for the flavors/aroma of these carts, customers seemed the most satisfied with this brand.

Users also seemed to enjoy the potent effects and quick action these carts have had on their anxiety and pain.

Even the retailers and wholesalers are happy with their business with this brand.


The brand’s policies regarding its returns, refunds, and exchanges aren’t very clear. There is also no way of contacting the customer support team directly over the phone or email. You can only leave a ticket on their contact us form.

Nevertheless, the customers are generally satisfied with their products’ performance. So, they’re not much to complain about.

#3. Boston Hempire’s Delta-8 High Life Vape Cartridges – 920mg

Yet another all-American brand, Boston Hempire uses only the best Colorado-grown hemp in all its products.

Boston Hempire’s “High Life” line of vape carts is complete with 920mg of high-quality hemp-derived delta-8 THC.

Like our other finalists, each of this brand’s 1-gram D-8 vape carts offers only pure, over 92% concentrated THC extracted from Sativa strains. They are all organically sourced, third-party lab-tested, safe, and potent products. Like the other brands in this list, Boston Hempire can boast of keeping D-9 THC in its carts within legal limits (0.3%).

The cartridge, which has a thread size of 510, offers a smooth taste, leaving users feeling calm and relaxed.

The product line comes in 6 variants – Gorilla Glue, Blue Dream, AK Therapy (AK47), Jack Herer, Mango, and Blue Ice. While the first three are gelato-flavored and the Jack Herer holds on to the signature tones of its namesake strain (also known as the ‘Emperor of Hemp’), the Mango and Blue Ice options bear their obvious fruit- and mint-flavored aroma.

Since this product is highly concentrated – even more than MCT oil carts – the brand recommends using the lowest heat setting for this product.

Boston Hempire is a well-loved brand with thousands of positive reviews pouring in every single day.


  1. 100% organic products
  2. Fast shipping; free shipping for orders worth above $99
  3. Safe, lab-tested, and potent products


  1. No returns of vape carts are entertained by the company
  2. Its information resources aren’t adequate for most consumers to get a good understanding of the brand, its core team, and its practices.
  3. Only 6 variants in flavors
  4. Not many choices in strains used


Interestingly, Boston Hempire is among the few cannabis brands that have succeeded in garnering more support for the development and manufacturing of delta-8 carts.

The taste and the effects of these products were so good that many weed users have switched to this safer option, as it provides the same buzz, but without its side effects, and with flavors that made them fall in love with D-8.

A lot of customers also appreciated the reasonable prices of these products, besides their quality and quantity.

The different effects of each of the products were also another attraction of this brand’s D-8 carts.

Except for the harshness of the puffs, which you may feel if you take a very long puff, users were generally satisfied with their immediate experience as well with their long-lasting effects.

Some customers also wished they added more Indica strains to their D-8 cartridge offering.

Customers were generally satisfied with the company’s customer service and responsiveness.


Although the brand welcomes customers to reach out to them over the phone, its customer support team isn’t the most efficient. Besides, some of its policies aren’t the most customer-friendly.

Buying Guidelines For Delta-8 THC Vape Carts

Delta-8 THC is a little-known analog and a derivative of Delta-9 THC that shares the same health benefits as its stronger and more unreliable sister. But its downsides are fewer and not as long-lasting as the latter.

Although D-8 carts are a tad bit harsher on your throat than D-9 THC carts, their upsides far surpass their downsides.

Like any other cannabinoid, inhaling Delta-8 renders the fastest and the most potent impact. Whether you need fast relief from pain and inflammation or just want to get a bit high after a long and tiresome day, vaping is always the best option (smoking not so much as it involves burning the plant material).

So, if you’re considering vaping delta-8 THC cartridges, you may want to know how best to judge a product before you buy than to regret it later on – or worse harm your health.

So, here are some aspects of the product and brand that you must look into before you place your order:

Quality: There are various ways of determining the quality of delta-8 products. However, the market is still quite unregulated for customers to gain much insight into the brands. The best we can do is check their lab reports to confirm their efficacy, safety, and potency – the three cornerstones of quality in this industry.

Purity: If you’re looking for delta-8 THC, that’s what you should get! Brands that have confidence in their products make sure to retain only delta-8 in their products, and nothing else. Some brands do sell products that also contain certain amounts of CBD and other cannabinoids. While they could be a good thing, in terms of the much-hyped entourage effect, it could even defeat the original purpose of consuming delta-8. But you should always avoid brands that include additives, sweeteners, and carrier bases.

Color: The liquid shouldn’t be dark reddish, brown, green, or purple in color, as that would suggest the lack of diligent filtration and distillation to remove the contaminants after the isomerization of D-8 THC from CBD or its extraction. Also, avoid a product if you find the liquid opaque and not clear and transparent. Only buy cartridges that contain a clear yellow, almost champagne-colored, or light pinkish liquid.

Lab testing: Brands that submit their extracts or products to be tested by third-party labs are obviously more reliable. Independent labs can verify their claims in an unbiased way, simplifying your selection process.

Ingredients: Always check the ingredients to ensure they don’t include any cannabinoids with very low potencies or out-of-place cannabinoids. For instance, acidic precursors of cannabinoids, varinolic or Varin cannabinoids, or p-cymene terpene (a byproduct of isomerization), could remain in the liquid contaminating the end-product and posing health risks.

Brand Reputation: It is always safest to buy from reputable brands with higher customer reviews. This is particularly true in this industry that is flooded by rampant dubious activities. The fact is that there are very few good brands to choose from when it comes to delta-8 carts. So, make sure to buy only from reputed brands.

Options/Variants: Sizes, potencies, and flavors are three parameters of any delta-8 cart that you can choose from as per your needs and liking. Most brands offer a wide variety to satisfy customers in every way they can. This way, you, as consumers, get to select the concentration that best suits your required dosage and you can enjoy the experience with your favorite flavor.

Pricing: This is yet another factor that would give you an idea of whether you’re being duped or are getting authentic, quality products. Extracting Delta-8 THC is difficult owing to its low content in natural cannabis. It’s no wonder it’s so pricey. However, be careful of brands trying to rip you off! Do thorough market research before you place your order.

D-8 carts are usually harsher on your throat and lungs than regular THC cartridges. However, when it comes to health benefits and side effects, D-8 is certainly better on all counts.

That’s why it’s best to take it slow with each puff with these carts and let the body adjust to its effects gradually. In the long-run, it is always safer and better for your health to use D-8 carts than THC carts – which are mostly illegal and allowed only in some states of America, except in cases of severe health issues and only under a doctor’s supervision.

Delta-8 THC: FAQs

Q: How to store delta-8 cartridges? Do I need to refrigerate them?

A: For the cartridges to retain their purity, the brand recommends you store them at room temperature and away from direct sunlight.

These products are best kept in a cool, dark place, where they can’t get exposed to heat or sunlight, as either could degrade the product’s potency. There is, however, no need to refrigerate it. In fact, the normal temperature is the best for cannabinoids to retain their potency.

Just make sure to place them in an upright position to prevent any leakage.

Q: How will I know if delta-8 THC is allowed in my state of residence?

A: Delta-8 THC is federally legal in the US. You can get products delivered anywhere in America as long as you do not reside in the states of Alaska, Arizona, Arkansas, Colorado, Delaware, Idaho, Iowa, Mississippi, Montana, Rhode Island, Utah.

Q: Can Delta-8 cart make me high?

A: Yes, it can and it should. However, it is a nice high – not enough to get you stoned. But, of course, you must take within limitations. Too much of anything is bad for health!

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

A: Yes. It is THC, after all. Even though its effects are far more subdued and controlled, you will fail a drug test.

You must understand that the instruments used in these drug tests aren’t as finely tuned as our bodies to understand the difference between the two. It cannot differentiate between different analogs of THC, although they can differentiate between CBD and THC. No matter what kind of THC you have consumed – delta-8 THC, 11-Hydroxy THC, or delta-9 THC – it will be the same for these drug tests.

Q: Is D-8 THC legal?

A: Currently, there is no federal scheduling against delta-8.

Owing to some specific state laws, however, it’s legally out-of-bounds for people of certain states, such as Alaska, Arizona, Arkansas, Colorado, Delaware, Idaho, Iowa, Mississippi, Montana, Rhode Island, and Utah.

Technically, natural, hemp-derived D-8 THC is legal. However, it’s not easy to extract large volumes of this compound from natural sources as only trace amounts of this compound are available in cannabis plants. Most brands produce Delta-8 products by synthetically converting CBD into delta-8 THC. Products made in this process falls under the illicit category, as per the DEA.

Q: Are there any specific strains that are high in D-8 THC?

A: Not really. The amount of delta-8 in any live cannabis plant is almost negligible, and most dried ones contain lower than 1% of this compound. To obtain this cannabinoid, manufacturers carefully extract it from the plants using numerous chemical processes.
