The man behind the brand is Craig Henderson. He is a combat veteran who served in Iraq and developed an interest in discovering what cannabis could do for medicinal purposes after he came back home from his tour. 

Initial research indicated that the plant was promising, but the psychoactive component of hemp had to be removed- this is how he discovered CBD. He saw how well the CBD with his community of veterans and decided it was time for him to begin making things all people could enjoy. 

It started the same way many small businesses do- in the garage. He extracted hemp into oil form, and after much effort, Extract Labs came to fruition. Now the company is booming, with 50 employees, two buildings for production purposes, and growth like you couldn’t believe. 

The Delta 8 cartridges sold by the brand are pure and safe. They are a great way to get started vaping CBD. These extract tanks utilize only terpenes and CO2 extracted distillate.

The limited but good flavor selection was also a selling point for the clientele. They noted the Sour Ghost had a peppery pine flavor to it, and the long draws could be a bit on the harsh side, but other than that, the price was right, and the feeling was great, too.

Things to Consider When Buying THC Carts:

Delta 8 THC is not a very-well-known analog and a derivative of Delta 9. It has many of the same benefits as Delta 9. The downsides are lesser, and it doesn’t last as long as Delta-9. 

Although Delta 8 carts are harsher on the throat compared to Delta 9 THC carts, the pros really outweigh the cons. 

As with any other cannabinoid, inhaling Delta-8 offers you the most potent and fast impact. Whether you are using it for quick pain relief or for inflammation, or just desire to get high after a long day, vaping is a good option compared to smoking, which requires you to burn plant material.

Thus, if you are considering vaping Delta-8 carts, you should know the best way to judge a product before purchasing it. You can also Check this Review to know which one can work the best for you so you don’t hurt yourself or end up regretting your decision later on. 

To help with this, we’ve rounded up the most important aspects of most products and brands you should look into before you spend any of your hard-earned money. 

  • Quality

There are a few different ways you can determine the quality of your delta-8 goods. However, the market is still a bit unregulated, leaving customers without a method of determining what’s good and what’s to be avoided. 

The best we can currently do is review lab reports to ensure these blends are safe, potent, and effective, which are three tenets of quality in the cannabis field. 

  • Purity

If you want Delta 8 THC, that’s what you should be getting when you buy it! Brands that are confident in their products are sure to keep only Delta-8 in their products and no other additives or synthetics. Some brands sell things that contain certain CBD amounts and other cannabinoids. 

This is a good thing thanks to the entourage effect, but it could defeat your purpose of buying Delta- 8 in the first place. It might be great for some, but not what others want, so buy according to your needs. But do always avoid brands that feature carrier bases and additives/sweeteners. 

  • Color

The liquid inside shouldn’t be green, brown, purple, or dark red. This would mean that inadequate filtration and distillation practices were used to remove the contaminants following the isomerization of Delta 8 THC from its extraction or CBD. 

Be sure you avoid any products if the liquid is opaque but not transparent or clear. You should only purchase cartridges that are champagne-colored, clear yellow, or light pink liquid. 

  • Lab Tests

Brands that submit their products or extracts to be tested via third-party labs are more reliable. Independent labs are able to fact-check claims in an impartial way, which makes your buying process a lot easier. 

  • Ingredients

Make sure you go over the ingredients to make sure they don’t contain cannabinoids with low potency or cannabinoids that simply don’t belong there. For example, Varin cannabinoids or vitriolic cannabinoids, p-cymene terpene (isomerization byproduct) could stay in the liquid, which contaminates the final product and poses a health risk to you.

  • Brand History

It is best to buy from reputable brands that have high customer reviews. This is true in the cannabis industry, where it is saturated with people claiming their product can do wonders for your health and well-being. There are only a few good delta-8 brands out there, especially when it comes to vape cartridges.  

Make sure you only purchase from good brands with a solid reputation and be sure to ask them any question you have before buying. Remember, a good brand will be happy to answer any queries you have with confidence. 

  • Variants and Options

Potencies, sizes, and flavors are three criteria of most delta-8 cartridges that you are able to pick from according to your own needs and wants. Many brands offer an extensive selection to cater to many different customers. 

This way, you can enjoy the concentration that suits your needs the best and enjoy the experience with a taste that’s right up your alley. (Our team, for instance, loves the fruity flavors!)

  • Prices

This is a significant factor that could show you right away whether you’re being sold down the river or buying authentic and real delta-8 THC. It is very hard to extract Delta-8 since the content of it is very low in natural cannabis. 

As a result, it’s very expensive. But pay attention to brands trying to rip customers off. Make sure you research the company first by reading about their extraction methods as well as customer reviews. Remember, cannabis is hot right now, and there are swindlers out there trying to make a quick buck!

Delta 8 carts are harder on our lungs and throats compared to regular THC carts. But when it comes to the supposed health benefits and the side effects, delta-8 is more favorable. 

This is why you should go slow with each puff and allow your body time to adjust to the effects gradually. In the long term, it will be better to use Delta 8 compared to THC, especially since the latter is illegal in many areas of the US except when a medical clearance is granted. Remember that Delta 8 has all the good parts of cannabis, but none of the stuff people don’t enjoy, like paranoia and anxiety.

FAQs About THC Cartridges: 

Q1. Are THC Carts Legal?

There is currently zero federal scheduling when it comes to Delta 8. However, thanks to some very specific state laws, it is actually illegal for folks living in certain states. For example, citizens of Colorado, Alaska, Arizona, Idaho, Mississippi, Rhode Island, Utah, Montana, Iowa, Arkansas, and Delaware are not permitted to buy or use this derivative. 

Technically speaking, natural hemp delta-8 THC is legal. That being said, it is not easy to get large amounts of this compound from hemp or other natural sources because only trace amounts of the components are available in cannabis plants. The vast majority of brands create Delta-8 products by converting CBD into Delta-8 THC. Products crafted under this process are illicit, according to the DEA.

Q.2 Are THC Carts Safe?

The answer is yes. This is THC, at the end of the day. Even though this THC’s effects are controlled and subtle, you are very likely to fail your drug test. 

The thing to understand is that the mechanisms used in drug tests are not fine-tuned as our bodies are when it comes to understanding the difference between Delta-8 and regular THC. 

The drug test your employer or organization uses cannot tell the differences in the two analogs of THC, but they are able to tell the difference between CBD and THC. Regardless of the THC you’ve taken, whether it is 11-hydroxy THC, Delta 9, Delta 8, or anything else, it is all going to come back the same on drug tests.

Q3. What Do THC Carts Feel Like?

Delta-8 THC vape cartridge can undoubtedly make you feel high, but users report that it is a much more pleasant high as compared to smoking cannabis via traditional methods such as using bongs or bowls or rolling them using rolling papers. 

It’s high that could help some users feel more relaxed, at ease, and happy. Some even state they felt a sense of clarity and focus. However, you must take this seriously and use only the recommended amount, and NEVER drive or operate heavy machinery while using it. As with anything, moderation is key. 

Q4.Are THC Carts safe?

Delta 8 THC is federally legal in America. You may have products delivered anywhere so long as you do not reside in Utah, Rhode Island, Montana, Mississippi, Iowa, Idaho, Delaware, Colorado, Arkansas, Arizona, or Alaska. 

Many companies will list where they ship on their website, so if yours is not on there, chances are it’s not legal in your state. You should also check with local laws and regulations to be 100% certain you are within the confines of the law. 

Q5.How do I Store my THC Vape Cartridges?

We all want our carts to remain pure and safe, so most brands recommend you store them away from direct sunlight and at room temp. Keep them in a cool dark place, where no heat or sunlight can degrade the potency of the product. You do not need to refrigerate the cartridges, either. 

Regular temperatures that are not too hot or too cold are great for helping cannabinoids retain potency. Just be sure you leave them in an upright position, so you don’t experience leakage. You could even place them into a plastic zip bag if you were concerned about that.

Q6. Any Particular Strains That Are Higher in THC Content?

Not in particular. The amount of delta-8 found in a live cannabis plant is negligible at best, and dried plants have less than a percent of this particular component. To extract this particular cannabinoid, producers extract it carefully from the plants using many chemical processes. 

The best, in our opinion, is the CO2 method, in which carbon dioxide is used to extract cannabinoids and other good compounds of the hemp from the picked plants. Three chambers are used. In the first, CO2, which is usually a gas, is converted to a liquid by increasing pressure and lowering temperature. Then the pressure and temp are increased until the liquid hits the “supercritical” point. 

Once it is in this state, it is pumped into the second chamber where the hemp is held. It passes through the hemp, thus separating oil from the plant. The CO2 and oil then go to the third chamber where CO2 and the oil separate, the CO2 evaporating. What’s leftover is the oil extract for use in the great products you see for sale here.

In Conclusion: Which THC Cart is Worth Your Money?

Hundreds of Vendors are selling Delta-8 THC Carts everywhere you turn nowadays. With black markets being a real and dangerous threat, you should be very careful about where you get your Delta 8 THC, but don’t worry about that. 

We’ve rounded up three to pick from, these three brands Diamond CBD, 3Chi, and Extract Lab Delta 8 THC vape Carts are effective and safe and will help you to feel more relaxed and happy. They also care about doing right by their customers. They ensure customers are happy and satisfied with each purchase. 

It is best to buy from reputed brands that have positive customer reviews. However, you should always consult your Doctor Before taking any of it, and then choose and see which brand works the best for you!
