THC Oil Pen Vape Cartridge Tests: Pesticides and Strength

THC Oil Vape Pen Cartridge Test Database

The following data and information shows the test results of brands of prefilled vape pen cartridges also known as oil pens. Pesticides are a constant issue in these cartridges and strength is often incorrectly claimed. These tests are both for pesticides and residual solvents. Please note that the results are those taken at the date listed on the test. Testing is becoming mandatory in more states so in the future many of these same vapes may be clean or already be clean now.

Much thanks to DatDude4510 on Instagram for allowing us to use his test results and starting awareness about this. We are including other test results as they become available. Cartridges results will be in alphabetical order by brand name. The FAIL indicates a fail on pesticides. Strength was also tested, but that can vary slightly test to test, so we did not put a FAIL if only strength was off. The cartridges tested are from California. A full list of cartridges that tested clean from this list is listed at the bottom of this page. We have recently partnered with cannabis lab consultants Digamma Consulting to provide more tests and should have these results up soon.

Recent Updates: 10/11/2018 Heavy Hitters coming up dirty again.

Alpine Vapor has been in the game a long time, we expected better. See our full Alpine Vapor review.

Bloom Vape (Bloom Brands) Pesticides Test – PASS Currently, Previous FAIL 

Bloom came out with a new test published on the back of their cartridge. Passed for pesticides. See below.

bloom brands pesticides and strength test
Coming in clean, yay!

It is good to see things are turning around for Bloom Brands, but we do keep a record of previous tests, as shown below.

bloom pesticides
Bloom is riding dirty.

Glad they came through clean recently.The oil came up dirty for pesticides in this test on 12/20/2017. At least it is pretty strong. Bloom Brands is not to be confused with Bloom Farms below, which tested clean.

Bloom Farms Vape Pesticides Test – PASS

Bloom farms test on 12/05/2017 came up clean. See below.

bloom farms another pesticides test
Bloom Farms vape is clean.

Brass Knuckles Pesticides Test – PASS Currently, Previous FAIL

Brass Knuckles has had their vape oil tested two times since and have passed. SC Labs is being sued in the Brass Knuckles lawsuit. Currently Brass Knuckles has switched testing providers and that information is shown below. There are other tests as well, but they passed too, so we are showing one for simplicity.

Current Passing Test

Previous Failing Test

Previous test was a fail.


Brass Knuckles vapes have been exposed for pesticides before, but now it is passing which is great! They taste good and deliver good strength. Check out our Brass Knuckles review for more info.

California Dab Company Pesticides and Residual Solvents Test – FAIL

California Dab Company’s Cannabis Infused Vape Cartridge – Sour Apple will do good with its 67.5% strength. Unfortunately, we all have to be wary specially if we still have to know whether the company is licensed or not.

california dab company sour apple cannabis infused vape cartridge
California Dab Company – Sour Apple Cannabis Infused Vape Cartridge

Below test result shows 67.5% THC content.

california dab company cannabis infused vape cartridge sour apple
In terms of strength, 67.5% is considered okay.

Tested positive to contain 7 CAT 1&2 pesticide, would you still sesh on it?

california dab company cannabis infused vape cartridge
Test result shows pesticide contents.

Dank Vapes Pesticides and Strength Test – FAIL

Dank Vapes pesticides result is finally out however it should be stated that there aren’t any pictures to show the actual item. Only direct lab results are shown below.

dank vapes pesticides psi labs
Dank tested positive in at least 5 types of pesticides. Bad news for Dank lovers out there.

Dank Vapes stregth test is shown below.

dank vapes strength test 70%
Dank Vapes strength test result is 70%.

The results shown above came from PSI Labs thru Permafrostlabs. Although it should be noted that no pictures of the actual items tested were shown. There’s a big chance they tested a fake Dank cartridge as they are made available everywhere. It’s really hard for us to verify this test yet.

Dank Vapes Pesticides and Strength Test – PASS

So I went straight ahead to PSI Labs and here’s the result from their website. Also, shoutout to Zack for pointing this out.

Below is a screenshot from PSI’s page showing Dank Vapes’ King Louie test result. Results showed 65.15% total THC.

Below shows the indication of a pesticide free concentrate.

Test results showed no foreign materials, pests, mold or fungus for Dank Vapes.


Delta 9 Pesticides and Residual Solvents Test – FAIL

Delta 9’s vape cartridges came in pretty strong at 76.5%. However, they failed for 5 different pesticides. Below is a picture of what a Delta 9 vape cartridge looks like.

Cartridges from Delta 9 may be riding dirty.

Below is the strength and residual solvents test. Delta 9 passed the residual solvents test.

delta 9 strength and residual solvents test
Delta 9 THC cartridges have pretty good strength.

Pesticides are shown below for Delta 9 in the test results.

delta 9 pesticides test
Failing for 5 pesticides is not a good look for Delta 9.

DynaPuff Pesticides Test – FAIL

DynaPuff came in dirty for a wide range of pesticided in their test. See below.

dynapuff pesticides test
DynaPuff tests dirty for pesticides.

The strength test for DynaPuff was very surprising. It came in super weak with a 16% cannabinoid profile.

dynapuff strength test
DynaPuff is one of the weakest vape carts out there.

Exotic Carts Pesticides Test – FAIL, Additional Result FAIL

Exotic Carts testing result is out. One of the most popular vape cartridges right now and widely pirated. Tested positive for 13 pesticides under Category 1&2. A cartridge with this much contaminants, would you still try it?

exotic carts
Has widespread availability but you might want to avoid this brand as much as possible.

Here’s the pesticides test results of Exotic Carts. As datdude41510 mentioned, a THC profile wouldn’t matter for a stuff that pops out at least 13 different pesticides and fungicides.

exotic carts contaminated
Exotic Carts is highly contaminated as shown in this result.
exotic cart black market street cart
As expected of a black market/street cart, it tested positive of pesticides.

FlavRx Pesticides Test – FAIL

FlavRx came out with weak and dirty cartridges. Comes in at less than 60% THC. No extra charge for the pesticides. Should be noted that FlavRx also has cartridges in Nevada, and there if it tests dirty they don’t sell. So might still be safe to vape in NV.

Flight Farms Pesticides Test – Pass

Datdute41510 tested this and came out clean. When actual test shot is available we will post it as well.

flight farms pesticides test
Flight Farms came back clean and strong.

At 81% cannabinoids, Flight Farms came in strong and clean.

Heavy Hitters Pesticides Test  – FAIL

Heavy Hitters came in fairly strong at 71% THC. Pesticides not looking good though. Test is of the Girl Scout Cookies strain vape cart.

heavy hitters pesticides test
At least Heavy Hitters has some strength.

Another disappointment as HH is pretty strong and seemed like a good value. See our in depth Heavy Hitters review for more info.

Adding to this another product from Heavy Hitters was tested, it is the Sky Walker OG and the bad news is, the pesticide test failed. Although it has a good amount of THC on it Heavy Hitters should make it safe as well. You may check the results below.

Sky Walker OG

Below is the disappointing result of the most recent pesticides and solvents test. Heavy Hitters fails again.


Hitone Pesticides Test – FAIL

Hitone is a brand out of the L.A. area.

hitone pesticides test
Hitone is riding dirty folks.

Besides failing the pesticides test, the oil is not super weak at 63% THC.

Himalaya Pesticides Test – Pass

Himalaya has a wide variety of cartridges from different strains, to name a few they are the Strawberry Cough and Super Silver Haze from the Sativa strain. Below you will see the THC and Pesticide tests of the two featured cartridges.

Strawberry Cough
Super Silver Haze

You can check the test for your self to prove that the cartridges are made safe and has enough strength.

HoneyVape Pesticides Test – Pass

Still looking for the original test and will add when available.

HoneyVape pesticides test
HoneyVape consistently comes up clean.

Ignite Sunset Sherbet Cartridge Pesticides Test – PASS

Ignite Cannabis Co. makes cartridges, nugs and pre rolls. Their Sunset Sherbet vape cart has been tested and came out clean of pesticides. However, we are unable to show its cannabinoid profile and residual solvent results.

ignite cannabis cartridge
Ignite Cannabis Co. – Sunset Sherbet Cartridge

The test results below show Ignite’s Sunset Sherbet is totally clean from pesticides.

ignite sunset sherbet vape cart
Ignite’s Sunset Sherbet vape cart is pesticides free.

Interstate 710 Pesticides Test – PASS

One of the few to pass! THC not super strong, but I would take clean over strong any day.

interstate 710 pesticide test
Test reveals this vape cart’s oil is free from pesticides.

This brand might not be available everywhere, but they do come up clean.

Jetty Extracts Pesticides Test – PASS

Jetty Extracts comes away with some clean stuff that also is strong.

jetty extracts pesticides test
Jetty comes in clean and strong.

The THC content was advertised at 3% higher. However, this is a small enough variation within reason. Would like to try Jetty oil in a Stiiizy style setup.

Kurvana Vape Pesticides Test – PASS

kurvana pesticides test
Clean and pretty strong.

Kurvana came through pretty strong and totally clean. This test was of the Blueberry strain vape cart. See our full Kurvana vape review. Should be noted that’s a review of the original Kurvana. Newer versions are supposed to be better.

LA Kush Pesticides Test – Previous PASS, Recently FAIL

LA Kush comes from the same makers of Flight Farms. Good strength at 79% and it passed clean for pesticides on the original test. New tests now show it coming up dirty.

LA Kush pesticides test
LA Kush makes clean and strong vape carts.

Below is the new test results for strength pesticides for LA Kush. It came out pretty weak for THC content, but it did pass for solvents.

LA Kush strength and residual solvents test
These cartridges are pretty weak at 48.5% THC.

Below is the pesticides test for LA Kush. This time it failed.

LA Kush pesticides test
Failing for pesticides, LA Kush goes to the dirty column.

Unfortunately, LA Kush went from a previous pass to a fail.

Mario Carts Strawberry Pie Pesticides Test – FAIL

A new product is added here and it is the Mario Carts Strawberry Pie. But sadly the pesticides test failed. And for the THC content we will consider it as low at nearly 70%. To check it yourself here are the results below.

Looks simple… Mario Carts!

Here is the result on the pesticides test.

How sad for Mario….

THC content…well a bit low for the strength.

I thought Mario is Strong but look a bit weak…

Well let see if Mario Carts will improve their cartridges.

Moxie Pesticides Test – FAIL

This was surprising. Moxie is known for making exceptional quality extracts. Turns out they have pesticides in them, as Moxie failed the pesticides test. This is a California cart Luckily, we used a Nevada cartridge in our Moxie cartridge review. In NV they do batch testing, so Moxie is probably still safe over there.

Strength test for Moxie came out good with a 77% cannabinoid profile. Still would not hit it if its dirty though. They also should update their cartridge style.

moxie vape cartridge strength test
Strength is good for Moxie.

OCPharms Pesticide Test – FAIL

OCPharms fails for five pesticides and it’s strength is a joke. Not that much more THC than regular weed.

OCPharms pesticides test
I’ll take datdude41510’s word for it.






We could not locate the actual test for this item. However, due to datdude41510’shigh credibility in this area, we will take his word for it.

Plug and Play Vape Pesticide Test – Pass

Plug and Play Fire OG

Plug and Play Vape pods had a good amount of THC at nearly 79%. You may want to check out our Plug and Play vape review. Below is the strength test.

THC strength was pretty good on the Plug and Play.

The second page shows that the Plug and Play OG is safe.

A clean result is nice to find.

Potters Cannabis Co Pesticide Test – PASS

Potters Cannabis Co recently changed their formula to a stronger THC percentage. 80.3% is good! We will be updating our Potters cartridge review soon. The first page is the strength test.

potters cartridge strength test
Coming in strong.

The second page of the report shows the results of the pesticides test. Potters is clean.

potters cartridge pesticides test
Clean across the baord.

The last page is the lab certifying the tests.

potters cartridge COA
Signed and approved, Potters cartridges are clean

Potters Cannabis Co comes through strong and clean.

Rove Vape Pesticide Test – PASS

In our Rove cart review we found some strong, thick oil. Well turns out it really is strong and it is free from pesticides.

rove vape pesticies test
Rove comes in clean and strong.

The few, the proud, the clean. Rove is delivering quality and decent strength at 70% THC. In Addition to this a test was made with Rove Featured Farms and it is not a surprise that it is strong and safe.

ROVE featured farms

Below are the Pesticide test result.

Pesticide Test…SAFE!

And here is the THC content test…

Look how strong it is…

Select Oil Pesticides Test- PASS

Select oil pestixides test
Select Oil comes out clean.

See our Select Oil vape review. The Select Elite cartridge was used in this test and it came out clean. Strength was decent too.

In addition to this, another product from Select Elite cartridge has taken the test and passed, it is the Select Elite Island Sweet Skunk. Below you will see the results of the test for pesticides and thc content of this said cartridge.

Select Elite Island Sweet Skunk

The test for pesticides came out that it is safe to use.

Pesticides test…Pass!

And for the THC content… You will not regret it, it has a very good amount in it.

At 86% THC content, you will love this…

Sure thing that the Select Elite cartridges are doing good.

space vape test result
These cartridges came to be strong, having a high THC level percentage.

Space Vape Test – PASS

space vape cartridge
Space Vape

As shown below. Space Vape came out at with a positive test. Passing with 91% THC as well as being pesticide free.

space vape test results
These cartridges came out to be very strong and potent.

Stiiizy Pesticides Test – Previous PASS, Now FAIL For Benzene

The latest Stiiizy test failed for Benzene, which is a solvent. See the below results.

That’s pretty disappointing. Stiiizy seemed like a really good product.

stiiizy strength test
Stiiizy did not come out super strong. Maybe its strength is in the vape tech.

This vape might be more about its delivery system than the strength of its oil, but it does hit stronger than anything else we have tried as far as prefilled THC carts go.

stiiizy pesticides test
Clean as a whistle. Sure does taste clean.

Stiiizy does pretty well and out of the box hits very strong. See our full Stiiizy review for more information.

Suicide Girls Pesticides Test – FAIL

Suicide girls peticides test
Suicide Girls are getting dirty on pesticides.

Pretty strong at 70% THC, but it does not make up for the pesticides in it.

Supreme Hybrid Pesticides Test – FAIL

Supreme brand may sound interesting but for its cartridge the Supreme Hybrid there is a different story. A test was conducted and the result is not good for the safety of the consumers. Below you can see the test results.

Check this out this is the Pesticides test.


For the THC content, let’s say that it needs some improvements.


Let us hope that Supreme will improve its cartridge.

THClear Vape Pesticides Test – FAIL

THClear pesticides test
Not out of the clear on pesticides.

Strength is OK, pesticides are not OK.

The Clear Pesticides and Residual Solvents Test – PASS

The Clear with their Classic Variety in Golden Goat flavor cleared on any pesticides. Only problem is it might not be strong enough to a regular user with sub 50% Total Cannabinoids. Check out the product below.

the clear classic golden goat
The Clear Classic – Golden Goat flavor

Below is the strength and residual solvents test. The Clear with 48.9% total.

the clear classic golden goat
The Clear with sub 50% total.

The Clear cleared on pesticides. See results below.

the clear pesticides test
The Clear came out clean of pesticides.

The Clear came out clean without any trace of Category 1 & 2 pesticides but might be too weak for regular users. I’d say to each his own as some want to last the whole day vaping while some choose to puff with instant big hits.

Treebase Klear Pesticides Test – FAIL

treebase pesticides test
Pretty dirty but strength OK.

Strength not too bad at 62% THC. Dirty on the pesticides.

VVS Vape Pen Pesticides Test – FAIL

vvs vape pens pesticides test
Sad results on pesticides but it is strong.

VVS does come in with some really strong THC. The delivery system of its dispoable battery is what made it seem so weak in our VVS vape pen review. 83% THC is the highest on this list.

WVapes Pesticides Test – FAIL

wvapes strength test
Decent strength.

Strength is decent for WVapes. Below is the pesticides test.

wvapes pesticides test
Riding dirty on four items.

Being pesticide free is more important than being strong, but dirty is dirty.

Meet The Clean Team

The following cartridges came out clean in alphabetical order:

Bloom Farms, Brass Knuckles, Flight Farms, HoneyVape,  Interstate 710, Jetty Extracts, Kurvana, Potter’s Cannabis Co., Select Oil and Rove.

Cartridges that were clean and then later tested dirty:

LA Kush, Stiiizy

These are California cartridges that were tested. States with strict testing laws may not have these same issues.These tests are from random cartridges by the above brands and it does not mean all their cartridges are dirty or all the above are clean. If you have any additional testing data you would like to submit, please email it to community@dabconnection.com.


  1. Could you possibly test exotic carts? They’re very controversial where I live and also the brand Aliens Rx, I think they make Brass Knuckles, I believe, which passed but I would like to be certain

          • You cannot buy these in a corner store in nyc yes exotic and Mario carts have chemicals in them as most do that we take in people who live in stated where it is not legal take the chance everyday with it because that’s all we can get so if it is advertised as 80-85% and your getting 70% it’s ok to them I was one of them so when you find out that Mario or exotics are what they are go choose something else o you can’t because it’s illegAl get my point it failed for pesticides but your shampoo has pesticides and ingredients that go in jet fuel but your hair isn’t falling out is it? Cough drops have pesticides in them but you don’t see your throat closing do you? Point I’m making is you hit it without knowing these results right?

        • bro hes talking about the packages. china makes copy packaging for everythign and sells it in bulk, ESP exotic. So yes they can be filled with anything lol. just check ebay or amazon and type exotic vape packages or similar variables/bulk in it. Exotic is the most commonly seen one but i even see fake brass knuckles packages on there. But simply put anyone can do it and that is why people have actually gotten exotic carts that smacked and then straight hot dog water. But if i had to throw out a number id say most of them have pesticides and very rarely over 70% THC

        • dylan clark https://www.ebay.com/i/113391752072?chn=ps look at that. Thats just exotic u can find almost every brand if u look and dif versions/better versions etc etc. Stay away from them man haha its honestly poison it took me a couple brands before i found that “real cartridge”. For me its these carts calls “Dabout” idk if its the real ones or fakes i just know the oil is the most potent and best tasting ive had. Found them in chicago this month.

  2. Could you test – Venom Extracts

    Seem like pretty good carts I’d like to know what the deal is with them…

    Thank you and keep up the good work!!!

    • Yes please test pv, they’re by far the most popular cart in my area of Michigan rn, would love to see what they turn out to be

  3. Can you test Madre? I love their cartidges and they say they’re organic. Would like to know if that’s true. Thank you for your time!

  4. Please do DANK VAPES
    Preferable blue dream, I’m vaping this right now it says organic but I want to know for a face that there isn’t any pesticides.

  5. can you try testing sky high cartridges they seem to be very popular in my area but i just don’t trust them due to not being able to find any testing results from them.

  6. Thank you DabConnection, datdude41510, & everyone else who is keeping this going!

    But back to what I was saying..

    Read the reviews before you write a duplicate one. The carts you’re asking for have already been asked by your fellow Charon so please for the sake of Ganja, can ya read the reviews first?

    Stiiizy has all of their lab test downloadable on their official site, btw.

    Dank Vapes should almost be done being tested & then they said they’ll proceed with what they want shortly after.

    Get out your instant minds. Things take time. Patience is a virtue. Smoke & be happy. Enjoy your day & your weed lol

    With all that being said, may you test the Palmas Cannabis Oil, please?

  7. First, thanks for all this work!

    Unfortunately, none of the carts I have access to have been tested here. Can you please test the following?

    TKO Extracts (I know this has been mentioned a lot already)
    UFO Extracts
    Arctic Labs
    Esco Extracts (named after Pablo Escobar lol, pretty absurd)
    Cali Exotics
    Alternative Pharms (not sure why they would want to conjure up associations with pharmaceuticals, but they seem pretty good)
    Black Market ____ (forgot last word in the name…labs, extracts, etc, they are all pretty similar haha. the 1g carts come in black tubes)


  8. THANK YOU!!!!
    Rove carts are better than stizzys – now i see why.

    Still gotta try those honeyvapes – waiting to see how the Pure carts come out.

    • Stiiizy seems to be all over the place. Their older cartridges are much better than the new ones. Another thing you will notice is it’s the hardware getting Stiiizy the harder hit. I would check out our refill Stiiizy guide and try another oil in there. More likely than not it will be stronger.

      Just got a new pod yesterday and it is terribly weak. I am really disappointed as are the other reviewers, since Stiiizy was awesome before.

  9. I have King Carts cartridges in Gelato, Siur Diesel, Girl Scout Cookies & Grape, however I can’t find ANYTHING about them. Could they be fakes? How mamy different ones are out there & why is there no info. Kinda scary!

  10. So do dankvapes have pesticides or no? I know it’s a packaging company and not a concentrate company, which most likely means the dark web vendors buy the packaging and fill them up with these pesties and other shit like terpenes to make it taste like the flavor / strain on the packaging, and sell them in bulk… how come there’s one dank test of king louie that failed and another one of king louie that passed and they’re both same THC%? Lol… give more info on danks please / run more tests

    • We are just posting all info that comes out as unfortunately there is nothing official for them. If you are in a legal state our advice would be stick to brands that are registered and meet testing requirements. Airo Pro and Select Oil are good options available in most legal states.

  11. What about Kingpen and Dank Vapes. I found the Kingpen is packaged very securely and is also very descriptive. Also what about cannasseurs club carts …..Thanks

      • I should just clarify none of the above tests are yet from us. We have two labs that soon should be publishing tests, but for now these are compiled from around the internet. In the future well be posting new ones and will continue to compile ones that are out there. Thanks to DatDude41510 on IG for providing most of them.

  12. Please test Colorado Cannabis Co cartridges, you can use the cannasaver coupon to get them for $14 a cartridge from Pure Marijuana Dispensary in Denver and I want to make sure I am not inhaling pesticides!

  13. Would you guys kindly be able to test ClearChronic carts please?

    On a side note, for those of you who are aware, how harmful are most of these fails? Pretty broad question, I know. But for example, since most people seem to discuss Dank on here, say I smoke one Dank cartridge a week that failed the test. Would this usually make someone sick to their stomach, loss of appetite, etc? Or god forbid put you at an extremely high risk of cancer? It appears for a lot of these companies that are failing, they are still below the amounts tested on rats across many studies that cause serious harm.

    TLDR; Are many of these carts capable of spiraling your health at a rapid pace from intaking about 1g per week?

  14. On Monday I had my first seizure of my life. My fiance thinks it’s from my cartridge. Sunday after work I fell asleep on the couch. I woke up around midnight and didn’t feel well. I threw up. My fiance came to bed with me to take care of me. He got up around 7am. I’m still sleeping. He said around 9am he heard a weird sound coming from upstairs. He goes to check it out and it’s me having a seizure. My eyes rolled back, foaming at the mouth, and having convolutions. He couldn’t get me to come to so he called 911. I was in the hospital about 36 hours. My brain scan came back normal as well as the EKG of my heart. I’m not prescribed to anything nor was I on any type of recreational drug besides thc. This is the first time I have ever had a seizure. And I’m definitely scared and worried. My fiance thinks I got a fake cartridge. And he doesn’t/didn’t smoke my cartridge. Has anything similar happened to anyone else??

    *I posted this same thing on a different article hoping to find some type of information.

  15. Can you test new mario carts very clear now and very strong the ones i have been smoking have been great for me and mine have a print and a mario cart logo inside of the wax and the packaging is rainbow im guessing as a way as to try and authenticate i just want to know so im not smoking my self to death or something.

What do you think?
