1. iDELTA8: The Best Delta-8 THC Cartridges Overall


  • Large selection of great delta-8 vapes as well as rarer formulas
  • Several great options for hemp-legal cannabis strains
  • Lab results are available and easy to find
  • Fantastic customer service and fair prices

Our top choice for the best delta-8 vape option was actually an easy one: iDELTA8. iDELTA8 has built upon their successes and developed a huge lineup of delta-8 vapes as well as other hard-to-find vape formula options, including a plethora of highly sought-after cannabinoids like HHC and delta 10 as well as strain-specific tinctures, topicals, and capsules. These options are not simple quick money grabs like some vape companies do (some just slap in a new cannabinoid and market it as a whole new product); rather, these are fully fleshed-out offerings in their own right.

As for the brand itself, iDELTA8 hit the ground running when they launched and have continued to blow away the competition in the delta-8 space ever since. iDELTA8 has shown both the drive to directly assist and inform customers through blogs and an outstanding service team, as well as a dedication to using only premium organic hemp plants.

What People are Saying About iDELTA8 

Perhaps the most universal response from people who try the iDELTA8 vapes is surprise. People are surprised at just how potent and effective delta 8 can be. For many, this compound is thought of as simply “weed lite” but the iDELTA8 formulas help these items transcend and take on a character all their own. In fact, many customers claim to have been converted from regular cannabis delta-9 THC to delta 8 after only a few puffs of the powerful Diamond Formula Vapes they have on offer.

It is rare to find potent, pure, and effective delta 8 in an easy to use vape form, so for many this was something they didn’t even know they desired. This is how iDELTA8 has made such a splash in the industry; turning expectations of what delta 8 can be right on its head. 

All that said, people also appreciate the top-notch customer service, reliable delivery, and consistent taste and potency these items provide. The only complaint we have seen are customers annoyed that the products only ship on business days.

What Types of Vape Cartridges Does iDELTA8 Carry?

A major selling point of iDELTA8 is their vast selection which spans several different types of hemp-derived cannabinoids. However, the items that really put them on the map are the lineup of delta-8 THC vape options in Silver, Gold and Diamond formulas, each a different ratio of CBD and delta-8 vape juice, allowing you to slowly grow into delta 8 use.

Here is a basic rundown of their essential delta-8 THC vape options.

  • iDELTA8 Premium Silver: The blend is two parts CBD to one part delta 8 and it is suggested that all who are new to delta-8 vape cartridges start here. This is the entry level delta-8 THC vape and was designed to give first-time users, or those who want a large portion of CBD, to get a nice mellowing effect. CBD interacts and tones down delta 8 in unique ways and this blend ensures you will receive all of the expected wellness benefits along with a very toned down, but deep and relaxing body-high.
  • iDELTA8 Premium Gold: The next step up in delta-8 THC strength is the iDELTA8 Premium Gold option. This is a 50/50 blend of CBD and delta-8 THC, and while it still offers a very relaxing and mellow high, it is noticeably more potent than the silver option. Many will stick to the Gold level, especially if they are seeking a much more calming and relaxing CBD-style experience with a good D8 kick.
  • iDELTA8 Premium Diamond: The Diamond formula is the pure delta-8 THC option and provides the purest and most potent D8 THC effects. 
  • iDELTA8 Premium Obsidian Vape Cartridge: The Obsidian Vape Cartridges are a combination of CBD, delta-8 THC, delta-10 THC, CBN, and THC-P, all in one cartridge. These are all unique cannabinoids that offer a blend of wellness and psychotropic relaxation.
  • Disposable Delta-8 Vape Pens: There is also a huge selection of disposable vape options made with various strains of pure delta-8 to choose from.

iDELTA8 offers a good variety of lab-tested hemp cannabis-derived terpenes. This means you have plenty of strains to choose from for your delta-8 vape cartridges. For example, the premium vape cartridges allow you to choose between Blackberry Kush, Blue Dream, Pineapple Express, Northern Lights, and many more. 

Final Notes on iDELTA8

iDELTA8 offers perhaps the largest and most unique selection of delta-8 vape cartridges on the planet. If you have ever wanted to experiment or test out this cannabinoid, their Silver, Gold, and Diamond experience is perfect, and if you are looking to get a simple pure blast of D8, then you have more than enough high-quality and rare strains to choose from. 

On top of the great choices, it’s important to remember that iDELTA8 also consistently offers high-quality and well-built vape carts, and everything they do is backed by a fantastic customer service support team. When you put all of these pieces together, it is easy to see why iDELTA8 is our choice for the current best delta-8 vape cartridges. 

All of the vape cartridges from iDELTA8 either fit 510 threaded cartridges or are disposable vape cartridges.

Secret Nature is known for offering artisanal CBD hemp flowers and oils, and their team has over two decades of experience working with, growing, and cultivating amazing hemp plants.

Secret Nature now offers a large selection of premier hemp-derived delta-8 THC products, including capsules, pre-rolls, and carts, and all of these items are created with the same care and quality that their CBD has become so well known for. 

What Types of Vape Cartridges Does Secret Nature Carry?

Secret Nature has two different options when it comes to the type of delta-8 vape carts they carry. They have the standard Super 8 delta-8 vape carts that fit the standard 510 batteries. These delta-8 vape carts are incredibly high quality and are made with live resin cannabis terpenes, so the taste, smell, and feel remain very natural and potent. There are also the disposable and rechargeable live resin vape pens which are much the same, but with a disposable pen body.

Both of these types of vape pens are available in a number of strains including OG Kush, Wedding Cake, and several others.

What are People Saying About Secret Nature? 

The words you hear most coming from Secret Nature customers are “smooth” and “relaxing” with many talking about these vapes as the perfect after work wind down treat. People also really appreciate the responsive customer service. The only complaint you will really find are those not used to live resin who do not like the need to preheat the pens before usage.

Final Takeaways on Secret Nature Products

These are fantastic products that are developed through a carefully managed manufacturing process that removes harmful carrier ingredients while still allowing you all the benefits of the hemp plants. They offer excellent customer service and you can always rely on the quality of the oil itself to be outstanding.

Just like their CBD, the delta-8 from Diamond is GMO-free, lab-tested, organically grown, and contains no added synthetics.

It seems the general consensus from those who have tried the product are very favorable, especially when it comes to the strength and flavor. The only recurring complaint you will find is that the occasional cartridge will malfunction. In our offices, however, we have not seen any evidence that the vape cartridges they use are any different from many other brands.

What Should I Look for When Buying Delta-8 THC Carts?

When you are looking for the best delta-8 vape carts there are a number of factors you will likely want to consider. The first rule is that you want to make sure that you are getting your delta-8 vape carts from reputable brands. 

But why is searching out reputable brands so important? The truth is that the cannabis industry is still very young and the regulations and certifications that protect other types of products simply are not in place to keep companies that CBD and delta-8 products in line. Instead, it is up to the consumer to ensure they are seeking out brands that are honest and transparent about what is in their products. This is also why choosing a brand that offers third-party lab testing is so important. All of the brands on this list, and many other top cannabis companies, all make a point of having their lab tests open and available for viewing by all consumers. 

You should also take the time to seek out reviews and opinions from consumers similar to yourself. A lot of different people take delta 8 and they often do so for very different reasons from one another. You want to seek out like minded-communities that will give you reviews of products from a situation that is similar to yours. For example, one who is taking delta-8 products recreationally may want something different out of their delta-8 vape carts than someone who is taking it to help take the edge off of draining medical treatments. 

One last little detail you should look for is whether or not they are proud to mention where the hemp they use is sourced from. Some companies put great effort into sourcing premium Colorado hemp, which in turn makes the best delta-8 vape carts. Other brands will not mention anything about the hemp plants used in their products. While not all the D8 you buy needs to come from Colorado, the better brands will generally have some story or detail to tell you about the hemp they use and why they have chosen those plants.

So, to recap, a good delta-8 cart comes from companies that:

  • Have a reputable name and a proven record
  • Offers 3rd party lab testing
  • Has many positive reviews from customers like you
  • Puts care and love into the sourcing of quality hemp

What is Delta-8 THC? Is Delta 8 Different from Delta 9?

Delta-8 THC is one of many cannabinoids found in the cannabis plant, and has only recently been isolated and sold as its own product. Delta-8 THC is very similar to the cannabinoid delta-9 tetrahydrocannabinol (delta-9 THC), which is the molecule known for giving marijuana the psychotropic effects known as a “high”. Much like delta 9, delta 8 provides the user with feelings of euphoria, happiness, pain relief, and more. However, unlike delta 9 which is derived from marijuana, delta-8 is sourced from hemp-derived CBD so it is a federally legal product (something marijuana derivatives are not).

Both D8 and D9 affect the body by binding to receptors within the endocannabinoid system. By binding with these receptors, these natural chemicals cause the feelings of euphoria and sense of intoxication. All of this overlap is due to the fact that these compounds are incredibly similar in their chemical structure. The real differences between D8 and D9 is in the different placement of their double bonds. Within the chain of carbon atoms these molecules contain, delta 8 has the double bond on its eighth carbon. Delta-9, on the other hand, has it on the ninth.

Long-time cannabis users, when asked to compare the effects of delta 8 and delta 9, will typically say that the effects of D8 were a little weaker, but felt smoother and caused fewer feelings of paranoia or stress. This is why many people undergoing medical procedures, like chemotherapy, will often prefer delta 8 over delta 9. 

To isolate delta 8 in large enough amounts typically requires a large amount of hemp-sourced CBD. Then through a process referred to as isomerization, the CBD is chemically converted to delta 8.

How are Delta-8 THC Vapes Different from CBD Vapes?

Both delta 8 and CBD are derived from CBD-rich hemp. As with delta-9 THC, CBD is a cannabinoid like delta-8 THC, however CBD does not cause any of the “high” feelings associated with the THC compounds. Instead, CBD is used to promote everyday wellness and to regulate the body’s systems. There is a large amount of evidence that taking CBD along with delta 8 can make both compounds much more potent than they would be alone.

As far as the vape carts themselves, these are exactly the same, only the internal cannabinoids they utilize are different. 

Are There Benefits to Taking Delta 8?

While delta 8 is often referred to as “weed light” for the mild yet potent high it offers, its effects may actually go much deeper. At its surface, delta 8 is great for that euphoric feeling and for unwinding after a busy day – it can also help to regulate your appetite and keep you eating at normal time. 

There have been thousands of anecdotal stories of delta 8 being used to help alleviate all sorts of other issues. Pain relief for chronic conditions is perhaps the most commonly stated one, with many using D8 and other cannabinoid products to help avoid needing to use prescription medications like painkillers that can be highly addictive. However, this will not work for everyone and you must always consult a doctor before adjusting your wellness routine.

The reason that D8 can have such a profound effect on both the body and the mind lies in an internal system we all have called the endocannabinoid system (ECS). We are still learning about the ECS, but what we do know is that the ECS runs throughout the body and contains receptors that help to regulate hormone production. Delta 8 interacts with the body by binding to CB1 and CB2 receptors, which in turn, can lead to a large series of benefits.

Are There Side Effects to Delta-8 THC?

There is a general list of adverse effects that people have felt taking delta-8 THC. In some cases this may be due to a faulty product, or the user was allergic to a carrier oil (like MCT oil) that may have been mixed with the delta 8 to improve absorption. In other cases some may not have known how many puffs of their D8 vape to take and then experience a very powerful high which made them uncomfortable. Each person reacts differently, which is why you need to start very small and slowly work your way up to a full dose of D8.

Some common side effects may include: hallucinations, anxiety, dizziness, confusion, and loss of consciousness.

Will Delta 8 Show Up on a Drug Test?

While delta-9 THC is the most common cannabinoid in marijuana cannabis plants, and what the drug tests are normally looking for, most drug test kits cannot distinguish isomers so it will read all various THC (delta 8, delta 9, delta 10, etc.) as the same. This means that although delta 8 may be derived from hemp, there is a chance it can cause a positive for marijuana usage.

Is Vaping Delta-8 THC Legal?

This is a complex question due to the layered legal system in the United States. The 2018 Farm Bill legalized hemp-derived products throughout the United States, however, in the following years some states have realized that this doesn’t consider newer products like delta 8 that can still get you high. Roughly a dozen states currently have taken steps to ban delta 8 from being sold in the state. This is why some places do not ship to Arizona for example.

Always check the local laws for the state, county and township where you plan to consume delta-8 products.
