Best Delta-8 Cartridge Review: Top 5

  • Diamond CBD
  • 3Chi
  • Boston Hempire
  • Extract Labs
  • Delta Effex

1. Diamond CBD

This CBD brand has branched out into the delta-8 field, and it extracts its cannabinoids from hemp. The Diamond CBD delta-8 cartridge contains an impressive 900mg of delta-8 AND 900mg of CBD. This product is part of the brand’s ‘Chill Plus’ range. It comes in various flavors, including Sour Diesel, Banana Kush, and Pineapple Express.


Diamond CBD uses supercritical CO2 extraction, and there are no artificial flavors or preservatives in these cartridges. With 1ml of liquid in total, you receive a reasonable degree of potency. Using it is as easy as attaching it to a 510-compatible battery. Diamond CBD only sells this product to customers aged 21+.

2. 3Chi

The 3Chi delta-8 cartridge range features two options: 500mg or 1,000mg extract in 0.5ml and 1ml of oil respectively. The brand claims that each one contains 95% delta-8-THC oil. This means you get 475mg of it in the smaller cartridge and 950mg in the larger one. There are also 5% cannabis-derived terpenes per cartridge.


3Chi is proud that it doesn’t use cutting agents such as VG, PG, or PEG. Instead, it relies on terpenes to make the oil easy to use. The cartridges have ceramic coils and are made from glass. 3Chi has even more flavors than Diamond CBD, including Blue Dream, Gelato, and Jack Herer.

3. Boston Hempire

As you can probably guess, each Boston Hempire delta-8 cartridge contains cannabinoids from hemp. What’s reassuring is that the hemp is cultivated in Colorado. Each 1 gram cartridge contains 920mg of delta-8, which equates to 92%. It also contains 4.76% CBN, but no CBD, CBDa, CBG, CBC, or delta-9-THC.


It doesn’t offer as many options as others on the list, but the Gorilla Glue, Mango, and AK-47 flavors are excellent. All of its products are organic and lab-tested. One major downside is that the company doesn’t seem to allow any returns.

4. Extract Labs

Extract Labs is yet another CBD company that has made the transition into delta-8. A combat veteran named Craig Henderson founded the company in 2016, and it is one of the most reputable around. He created it in his garage and grew it into a relatively large organization in Colorado.


The Extract Labs delta-8 cartridge contains distillate and terpenes extracted from cannabis using CO2. The oil doesn’t contain traditional fillers like MCT or thinning agents. The Extract Tanks contain 500mg of delta-8-THC, CBG, and CBD. They are compatible with 510-threaded batteries.

The main downside is the lack of flavors. You can only choose from Ogre Berry, Sour Ghost, and El Jefe at present. Nonetheless, with no unwanted ingredients, Extract Labs offers a pure and high-quality product. You can also purchase delta-8 distillate in bulk.

5. Delta Effex

This brand sells delta-8 and delta-10 products. It has featured in major publications and is developing a reputation for excellence. The Delta Effex delta-8 cartridge range comes in six flavors, including Cali Orange Kush, Strawberry Cough, and Grand Daddy Purp. This brand is different from others on the list because it was created specifically to sell products like delta-8.


It offers the lowest delta-8 concentration on the list at 70% in some products but provides a smooth vaping experience. However, it does sell other D-8 vape cartridges with up to 92% of the cannabinoid. While Delta Effex doesn’t have as many flavors, it sells a greater range of delta-8 products than most brands.

What Is a Delta-8 Cartridge?

A delta-8-cartridge is pre-filled with oil that contains a high percentage of the cannabinoid. Manufacturers use sophisticated equipment to extract delta-8-THC from the marijuana plant. It is a painstaking process since most cannabis strains contain less than 1% of delta-8. In contrast, modern-day strains often have over 20% delta-9-THC, the better-known version of tetrahydrocannabinol.


These cartridges are extremely concentrated products designed for vaping. Those who use delta-8 vaping products say that it is a relatively harsh cannabinoid. Therefore, it is advisable to take small puffs, or else you risk experiencing a coughing fit.

How Does Delta-8 THC Make You Feel?

Delta-8 is similar in structure to delta-9-THC but with some significant differences. Most notably, delta-8 is about half as potent as its more famous cousin. Consequently, the delta-8-THC experience is said to be a lot more clear-headed, chilled out, and manageable.

Essentially, while both cannabinoids will make you high, delta-8 is much more subtle. This makes it a great option for those who haven’t tried traditional marijuana. It’s only mildly intoxicating, so in some cases, you may not even feel the high. It depends on how much of the cannabinoid you consume.

Moreover, one of the biggest advantages of delta-8 over delta-9-THC is that it isn’t likely to cause anxiety or paranoia, both of which are potential side effects linked to delta-9. Instead, you can expect a sublime sense of relaxation in the body and mind.

What Are the Benefits of a Delta-8 Cartridge?

One of the main delta-8 cartridge benefits is the fact you receive distillate oil formulated with the cannabinoid. Remember, there is relatively little delta-8-THC in cannabis flower. There are also several other pros:

  • Vaporization offers a faster absorption rate than tinctures and gummies infused with delta-8. You also benefit from a higher bioavailability rate than almost any other form of consumption.
  • Vaping is less harsh on the lungs than smoking. Therefore, it would make sense to get a delta-8 vape cartridge even if there was plenty of the cannabinoid in cannabis flower.
  • The rapid growth of the industry has led to a significant increase in the number of available flavors.
  • Each vape cartridge contains a pre-filled amount of oil and a clearly outlined delta-8 level. Therefore, it is possible to calculate how much of the cannabinoid is in each puff.
  • One of the most obvious benefits of a delta-8 cartridge is its convenience. You can take it out and enjoy a quick vape anywhere you go. However, please remember that delta-8-THC from cannabis is subject to the same legal restrictions as delta-9-THC.

Also, the delta-8-THC cannabinoid is linked with a similar array of possible therapeutic benefitsa as delta-9-THC. For instance, a study published in 2004 found that delta-8 was effective at increasing appetite in mice.

As delta-8 doesn’t bind to the CB1 receptor as tightly as delta-9, it is about half as potent. Despite less intense effects, it is seemingly more effective than delta-9 for a wide range of functions.

The lower level of intoxication also reduces the risk of adverse effects such as paranoia and anxiety.

How Much Delta-8-THC Should I Consume?

As with any cannabinoid, finding the ideal dose of delta-8 THC to consume is challenging. Every person is unique and responds differently to certain cannabinoids, depending on a number of factors. Some of these include metabolism, body chemistry, weight, and cannabinoid concentration.

The amount you inhale, the rate at which you puff, and the temperature can all have an impact on how much you ingest.

Plus, vaping adds an extra layer of confusion because it’s difficult to tell exactly how much of the cannabinoid you are consuming. Although you have reasonable control over each “hit,” it’s not easy to determine how many milligrams are in each puff. Additionally, the amount you inhale, the rate at which you puff, and the temperature can all have an impact on how much you ingest.

The best way to find your perfect dosage is by experimenting. We recommend starting slow and increasing your intake gradually, as and when required. For instance, start with just one or two deep inhales, and wait at least 30 minutes before consuming any more. You can carry on this process until you experience the desired effects.

Remember, the more you consume, the more intense the effects will be, and the longer they will last.

Is There a Risk of Building a Tolerance to Delta-8?

Unfortunately, one of the drawbacks of delta-8 is that you run the risk of building a tolerance more quickly than with cannabis and other cannabinoids. This means that you will reach the point where effects are lessened – and you need to consume more of the cannabinoid to get the same results – sooner.

According to anecdotal reports, if you consume the cannabinoid regularly for four weeks, you may need to increase your dosage to experience the same effects.

Fortunately, there is a way to prevent this outcome, and it involves taking tolerance breaks. This is exactly what it sounds like – a break from delta-8 use in an effort to lower your overall tolerance. For instance, you can abstain from using the cannabinoid once every two or three weeks.

Alternatively, use the cannabinoid in moderation. So, have a few puffs once every other day or only when you really need it, like after a long stressful day.

What Are the Side Effects of Delta-8?

Research on delta-8-THC is still in its infancy. Therefore, there isn’t much clinical evidence regarding the safety of the cannabinoid. However, anecdotal reports suggest that delta-8 has a high safety profile. Moreover, the cannabinoid has not been linked to any severe or life-threatening side effects.

However, there are a few potential side effects that you should be aware of when consuming delta-8. These include but are not limited to mild drowsiness, fatigue, dry mouth, dry eyes, irritability, and dizziness. Also, although it doesn’t pose the same risk as delta-9-THC when it comes to inducing anxiety or paranoia, both of these scenarios are possible if you overindulge in the cannabinoid.

It’s also important to note that other ingredients used in certain delta-8 cartridges may be harmful to your health. Therefore, it’s important to check ingredient lists to see exactly what you’re putting into your body.

Additionally, always be sure to check Certificates of Analysis (CoA). These are third-party lab reports that confirm products are free of herbicides, pesticides, heavy metals, and other potentially harmful ingredients. Some companies may use chemical fertilizers when growing their hemp, and this could affect the end product. If brands don’t publish CoA’s for customers to view, steer clear.

How to Choose the Best Delta-8 Cartridge?

There is no difference in the criteria between choosing the best delta-8 cartridge or any delta-9 or CBD oil cartridge. Here are some things to consider:

Plant Source

Look for brands that get their delta-8 from licensed marijuana or hemp farms. Ideally, the plants are grown in the United States or Canada, although several EU countries cultivate high-quality cannabis and hemp plants. Please don’t take any risks by choosing a company that fails to provide details of where they source their material. Some brands extract delta-8 from hemp. At the time of writing, that is technically federally legal due to the 2018 Farm Bill.


Whether it is CBD, delta-8-THC, or delta-9-THC, try to avoid brands that use solvents to extract plant compounds. CO2 extraction is ideal as it doesn’t involve the use of solvents.

Third-Party Lab Reports

The delta-8 vape cartridge industry is relatively new, and regulation is far from watertight. Therefore, you should only buy products from brands that can provide certificates of analysis for their vape oil. Cartridges without lab testing could be full of contaminants such as residual solvents or vitamin E acetate.


Lab reports and a list of ingredients also tell you whether there are things you don’t want in your body in these products. High-quality delta-8 cartridges don’t tend to have thinning agents such as VG or PG. They also don’t contain insecticides, pesticides, or heavy metals.

Is Delta-8 THC Legal?

Delta-8 THC is currently stuck in a somewhat legal gray area. There is no federal scheduling against the cannabinoid, which means that it is technically legal.

The 2018 Farm Bill classified hemp and hemp-derived products as federally legal as long as the THC level does not exceed 0.3%. Therefore, delta-8 that is sourced from hemp, is considered to be legal. However, if it’s sourced from high-THC marijuana or if the delta-8 cartridge you purchase contains more than 0.3% delta-9-THC, it will be classified as illegal.

Many companies produce delta-8 products by synthetically converting CBD into delta-8 THC. This method is federally legal.

It’s not easy to extract delta-8-THC in large volumes from natural sources because it is only available in cannabis plants in small quantities. Therefore, many companies produce delta-8 products by synthetically converting CBD into delta-8 THC. This method is federally legal.

That said, certain states have explicitly banned the sale of delta-8-THC, thus making it illegal in these parts of the country. They include Alaska, Arizona, Arkansas, Colorado, Delaware, Idaho, Iowa, Montana, and Utah.

Bottom Line on the Best Delta-8 Cartridge

Looking for the best delta-8 cartridge involves a lot of research, which is why we have done much of it for you. In a fledgling industry, we feel that the above five brands are among the best D-8 providers around.

When looking for a delta-8-THC cart, make sure you buy from a reputable source. In general, the cannabinoid comes from the hemp plant, but some brands may extract it from marijuana – which would make the product illegal. Above all, please ensure the cartridge comes with third-party lab reports.

Remember, every person is different and is, therefore, likely to have a unique experience with delta-8-THC. But if you buy a high-quality product from a trusted brand, like one of the five we’ve mentioned here, you’re almost guaranteed a pleasant experience with the best possible outcome.
