Here are our picks for the cleanest and strongest delta-8 THC cartridges from the most reputable brands on the market now. Although you can find more potent cartridges at lower price tags in retail stores and gas stations, the quality is often questionable. That’s why we’ve vetted over 100 delta-8 brands to recommend only the most credible and cleanest options. So here are our picks:Our Pick Price D8 Potency Binoid $29.99 990mg 3Chi $29.99 960mg Harbor City Hemp $35 930mg Delta Extrax $29.99 900mg D8.co $29.99 840mg MoonWlkr $39.99 800mg
Available for $29.99 from Binoid
Binoid, a brand with a name that makes them sound more like a robot and less like a hemp company, is currently making the strongest delta-8 cartridge that you can get online.
Their Guava strain sits at an impressive 99% delta-8 THC mark. Guava is a fruit used often in the making of jellies, which fits because a cartridge this strong will have your brain and body feeling like a spreadable condiment. It’s also shocking that a brand like this, that pulls off a potency like that, charges only $29.99 a cartridge. Sometimes you don’t need to be a billionaire to go to the moon, you just need some Binoid.
Available for $29.99 from 3Chi
Often considered one of the most popular delta-8 brands, 3Chi is here to challenge the throne as one the strongest delta-8 cartridges currently available. Though they offer nearly 50 different strains of cartridges, a robust selection to say the least, we’ll focus here on their Cali-O strain.
Lab results show this cartridge tests at a whopping 96% delta-8 THC while also coming back clean from toxins, heavy metals, and pesticides. To get that potency and that quality in a cartridge is truly rare. This is one of those one-puff-at-a-time type deals; take it slow, let it hit you, then have some fun. And at $29.99 even your wallet will be smiling as much as your goofy stoned face.
Available for $35 from Harbor City Hemp
Harbor City Hemp, a Florida based brand with a catchy name and a punchy product, finds themselves as an intriguing contender in the fight for the strongest delta-8 cartridge.
Offering both CO₂ extracted and steam distilled cartridges, 16 different strains, and comprehensive lab reports to accompany their products, this is one of those companies that you can feel safe purchasing from. But strength is why you’re here, not strains or paperwork. And strength is something these guys have. Their most potent distillate came back with a 93% delta-8 THC concentration; which means you’re going to be 100% stoned after giving them a try.
Available for $29.99 from Delta Extrax
Delta Extrax is offering a small line of delta-8 THC vape cartridges sitting in the 90-91% range. This is a company with mixed reviews, some people love what they make and some people say to yield caution. As previously stated; this is a potency list, so the fact that they test at 90% is why they’re on here.
Outside of that, their testing doesn’t include reports on pesticides, toxins, or heavy metals. Hence the yielding caution. There are six strains to choose from, they’re relatively inexpensive, and enough people have said they’ve enjoyed the effects. They could be worth testing, but for my money I’m choosing one of the above brands instead.
Available for $29.99 from D8.co
D8.co is one of the hardest brands to write about because they named themselves after the damn product. Every article about them quickly turns into an Abbott and Costello sketch. Quirky name choice aside, this is one of the most surprising and effective delta-8 cartridges being offered.
Though lab results show D8.co testing at 84% Delta-8 THC, I’ve sampled this cartridge on numerous occasions and each time it holds its own, if not exceeds, the higher potency options. Don’t let the numbers fool you, this is a smooth and sweetly strong option. Few cartridges have relaxed me as much as their carts. These carts cost only $29.99, are chock full of cleanly tested ingredients, and will supply you with a deeply euphoric experience.
Available for $39.99 from MoonWlkr
MoonWlkr has easily become one of the most recognizable names in delta-8 – continually pump out superb products with noticeable effects and that starts to happen. Their delta-8 cartridges are no different. The selection is small but the quality is noteworthy. Seven pages of clean lab results accompany each cartridge.
There’s no guessing with MoonWlkr, you know exactly what you’re getting. This is the type of vape where the effects will be quick, they start at the head and disperse evenly throughout the body. The one downside? At $39.99, for an 800mg cartridge, this is a very pricey product considering the same quality of product is available for cheaper.
Max Potency doesn’t necessarily mean this is reserved for those with the strongest tolerances.
I’ve found that some of the cleanest products on the market, free of toxins and pesticides, have the highest delta-8 concentrations. It makes sense because with more delta-8 put into a product, the less cutting agents are needed. So when that high percentage of delta-8 THC pops on a lab result you know there’s a smaller chance of tainted ingredients. And with cartridges, you can take one puff and put them down.
So these are products anyone, even beginners, can experiment with. You choose how much you want, when you want it.
The most potent delta-8 cartridge we could find online came in at 99% (990mg) delta-8 THC oil from Binoid. There’s a handful of others that sit in the 90% range, and it’s not rare to see credible brands coming in with 80% (800mg) concentration.
Numbers can sometimes just be numbers though. Cannabis is such a unique experience for so many. There are some 80% cartridges that have hit me harder than 95% cartridges.
What you want to ultimately look for is a clean product that’s been tested, then start sampling these and find which suits you best. Anything above 80% should, if legit, be able to produce notable effects.
If you’re looking for the strongest delta-8 THC vape cartridge, Binoid is leading the class with the highest grade of a 99% delta-8 THC oil vape. But with countless companies currently churning out clean, safe, and effective cartridges, this list will provide you with a wide range of choices to explore.
Vaping delta-8 is one of the best ways to not go overboard and take it puff by puff as the day goes on. With all these brands you have the choice to take a few puffs and move about freely, or hunker down, rip a plethora of pulls and melt into your favorite couch. That’s the beauty of a cartridge. You’re the conductor of your own high. And as the conductor, we’ve given you quite a few options to steer, so hopefully this list helps you find your best high.
