Creators of the Hollyweed CBD brand built it around a singular vision of wellness in its entirety. This includes physical, spiritual, intellectual, emotional, and social health.

HollyweedCBD takes delta-8 as more than just another commodity to sell and instead integrates as part of a healthy lifestyle. You can easily see this in all their CBD and delta-8 products, especially in their THC cartridges.

#4. DiamondCBD: Popular Brand For Thc Oil Cartridges


DiamondCBD started as one of the pioneers in the CBD industry. It was founded by a team of doctors, scientists, and researchers with extensive experience. The brand goal was definite from the start – to research and develop innovative CBD hemp extract. DiamondCBD also wanted to increase accessibility to these products. So when delta-8 popped up as a milder substitute for the more “rocky” delta-9, it swung into action.

Using hemp naturally grown in the United States, DiamondCBD started offering novel Delta-8 products. These include edibles like gummies, capsules, oils, and THC cartridges. Staying true to their vision of making hemp products more accessible, DiamondCBD now partners with many other quality brands.

All DiamondCBD collections and affiliated brands share the same qualities – high-quality delta-8. Delta-8 occurs naturally only in low quantities in hemp plants, so CBD is extracted first then isomerized to delta-8. DiamondCBD was one of the first companies to come up with a more innovative approach to this production.

How We Chose These Products

In creating our list of the best THC cartridges, we had a lot of options to select from. Many of them had some very outstanding claims as to the effectiveness of their products. So we had to make a list of criteria we used to create a standard to evaluate the products. Here’s what we looked at:

Delta-9 Content

While delta-9 sounds similar to delta-8, both are entirely different compounds. Delta-9 is a cannabinoid that mainly comes from marijuana. When present in a relatively small amount (0.3%-0.9%), delta-9 can increase the effectiveness of other cannabinoids.

However, the problem with delta-9 (and Marijuana generally) is the high level of psychoactivity. There are also other health and medical complications associated with this compound.

As a result, the legally acceptable limit for delta-9 is 0.3%. At this concentration, it can boost medical benefits without causing attendant harm. Therefore, in creating our top products, we identified brands that used within-limits levels of Delta-9 in producing their THC cartridges.

Hemp Source

We decided to go with only those THC products whose hemp source was from the United States. Since quality assessment of imported and foreign hemp is not always concrete. This may increase the level of toxic impurities present in the plant.

Also, with hemp products grown on farms in the United States, on-site tests are possible to determine the THC content. Researchers also optimize other factors such as soil type, planting, and harvesting techniques to get the best plants. This may not be verifiable for imported hemp.

FDA Guidelines

Many people would swear by the therapeutic powers of CBD and delta-8. However, research is still underway to truly determine the health benefits and probable side effects that might come with these compounds.

Therefore, we stuck with brands complying with the FDA and other legal regulations regarding cannabis and cannabis products in choosing products for this list. These include disclaimers as implied health benefits and age verification.

The FDA has not officially approved delta-8 THC as a drug yet. So, in creating this list, we selected products that were transparent with their claims and complied with all health and legal requirements.

Resources Available

Delta-8 products are still relatively new. There are still a lot of questions and speculations surrounding its use. Quality resources concerning how to use and maximize the benefits of THC cartridges are thus beneficial to beginners. It is also easier when the brand of your choice has detailed steps and resources regarding how to use the cartridges. Therefore, we selected only products with helpful resources and materials on their websites.

Having quality resources also demonstrates the expertise of a brand about THC products. Since we wanted only the top products, this was an essential part of our selection process.

Important Factors to Keep in Mind When Buying Delta-8 THC Cartridges

Choosing a THC cartridge can be overwhelming for a beginner. With all the variety of flavors available out there, you might find it all confusing. So we created a buying guide to help you navigate this process better.

Legal Status in Your State

The legal status of delta-8 THC products is a little bit controversial. However, here’s the breakdown. We can broadly classify cannabis into two types; hemp and marijuana. While hemp is legal in all the states of the US, Marijuana is illegal and a prohibited substance.

This is mainly due to its high delta-9 THC content. Delta-9 THC is responsible for the intense “high” that comes with smoking or vaping. Also, it is addictive and may cause health issues. Hemp also contains delta-9 but in relatively lower amounts. Generally, delta-8 extracted from hemp is considered legal, while any marijuana extracts are deemed illegal. Additionally, delta-8 produced through synthetic means are classified as unlawful.

However, extraction of delta-8 directly from hemp is not economical. Therefore many companies use CBD, which is legal to produce delta-8. While this process is technically legal, some states frown at it. Hence, it is essential to check out your state’s regulations on delta-8 products before ordering one.

Ingredients Used in the Cartridge

A THC cartridge is only as good as the ingredients in it. Ideally, the two significant constituents of THC cartridges are delta-8 oil and terpenes. The quality of the delta-8 oil depends on the CBD it is extracted from. This ultimately brings us back to the quality of the hemp used; organic, whole plant hemp contains richer and high-grade CBD.

So it is vital to check the origin of the hemp used in the production process. Usually, hemp sourced from farms in the United States is often subjected to quality assessment tests while still on the field. Therefore, they are of a higher grade.

Botanical-derived terpenes may taste and smell better than cannabis, but cannabis-derived terpenes and live resin contain a lot more beneficial cannabinoids.

Manufacturing Safety

Delta-8 extraction is a.complex process that requires a lot of professional expertise and advanced equipment. You should be wary of brands that advocate their delta-8 products are “home-made.” The extraction process can generate a lot of chemical impurities, so it requires competent hands.

The brands you want to buy from should adhere to Good Manufacturing Practices and use premium extraction methods. This includes critical, supercritical CO2, and other similar methods. The more transparent a brand’s manufacturing process, the more you can rely on it. You should also look for brands that test their raw materials before production.

Cartridge Potency

The ideal delta-8 THC cartridges should have a potency that is midway between that of CBD and delta-9.

CBD products are known for their therapeutic effect, while delta-9 is more known for the intense “high” feeling it produces. A potent delta-8 cartridge possesses some therapeutic effect and creates a smooth feeling of being high. Thus, making it an excellent way to relax without the harmful effects of delta-9.

The cartridges should ideally contain 95% delta-8 oil, 5% terpenes, and a delta-9 THC concentration of not greater than 0.3%. Any amount of delta-9 THC greater than 0.3% is illegal and may have adverse effects.

Many THC cartridges usually contain up to 90mg of delta-8 in one ml of oil. While this might not necessarily be the same for all brands, be sure to check out the composition of your THC cartridge.

Third-party Lab Testing

Third-party testing is probably the most important criteria to pay attention to in purchasing a delta-8 product. Third parties laboratories help to evaluate and assess the claims of hemp products. Allowing third-party testing also means a brand is being transparent with the process of its products.

It would also be best to check for the test results of the THC cartridges you want to buy on its website. You can also ask the dispensary unit if you’re purchasing from a physical store. Products that have undergone proper lab testing will usually have certificates of analysis (COA). Lab test results and COAs are significant in avoiding scams and fraudulent delta-8 products.

Brand Reputation

When it comes to delta-8 products, reputation is everything. You are better off buying from a well-established brand or at least a brand with some credits in the cannabis market. With the spontaneous increase in the number of brands offering delta-8 products, this is important.

Use customer reviews websites like Yelp and Trustpilot to check out reviews and customer feedback. You should also check for a physical address. While many brands offer their products online, a good number still have a physical office you can walk into or at least their contact information. A brand with no contact address or contact information is more likely to be a sham. If you are ever in doubt about the company’s integrity, be sure to conduct online research before ordering a product.

Cartridge Material

The last thing you want is a cartridge that leaks into or contaminates your delta-8 oil. Standard cartridges have ceramic, titanium, or quartz containers. These materials do not react with the oil or leak into it, thereby providing the perfect insulation from the external environment. They can also withstand cold and heat. However, storing the cartridges at room temperature is still wise to keep them safe from harsh cold or heat. Ceramic cartridges are generally regarded as the best because they produce the smoothest vaping experience.

If a poor material is used to construct a THC cartridge, metals and other impurities can leak into the oil. This can cause a change in taste and psychoactivity. It can also lead to poisoning depending on the severity of the contamination.

Frequently Asked Questions

Q1. What is a THC cartridge?

THC cartridges are small glass tanks that serve the purpose of holding THC oil. They often come prefilled and are disposable. THC cartridges typically work by connecting to the vaporizer (a small device that helps heat the oil in the cartridge).

Once the oil is heated, you can use the mouthpiece and enjoy your favorite strain of THC. There is also no smoke or lingering odor, so you can use it discreetly without attracting unwanted attention.

Q2. How long do THC cartridges last?

Most THC cartridges come with an expiry date, usually 12 months from the production date. If you are buying from a physical store, you can quickly check the expiry date on the pack. However, if you’re ordering online, your best option is to buy from a reputable brand. Such a brand will deliver only recently produced THC cartridges. Regardless of the “official” expiry date, there are several factors that can either make your THC cartridges last longer or reduce their shelf life. They include exposure to sunlight, air, and heat. Thankfully, expired thc oil cartridge is not poisonous, but you are better off sticking with unexpired ones.

Q3. How to refill THC cartridges?

Refilling your THC cartridge is straightforward. The process involves using either a syringe or an eyedropper. You can either make the oil you want to use for supplying or buy a prefilled syringe. The first step involves removing the mouthpiece, after which you can up the cartridge using your syringe.

If you cannot remove the mouthpiece, it means your vape pen does not have a refillable cartridge. You will either need to buy a disposable vape or go for one with refillable cartridges. After filling up your cartridge using the syringe, replace the mouthpiece and make sure it fits properly.

Q4. Are THC cartridges interchangeable?

Yes. THC cartridges can be designed for a specific vape battery. But in most cases, they are easily interchangeable, as long as the spare uses the same connection (510-threadings are the most popular types of relationship).

However, if you cannot exchange your vape pen cartridge, it means your vape pen does not support your spare. Check at your local dispensary for a replacement or a new vape pen.


THC cartridges are a much better way to enjoy the benefits that come with delta-8 than smoking. However, with the sheer number of products available in the market today, it is easy to get overwhelmed and make the wrong choices. A low-quality THC cartridge will scam you off of your money, and not to mention the health issues it might bring about.
