In case you've been living under a rock, all the rage over on ECR is the recent post by Russ from Click Bang about Vaporshark undertaking a massive endeavor of having every single juice from every manufacturer they carry tested for DA/AP. Some of the results are bad, very bad. A few of the juices are well over 1000 ppm. To make matters worse, some of these juices with high amounts are touted by the manufacturer as being DA/AP free.
So what's a DIY'er to do? How can we be sure that our favorite DA/AP free recipes really are free of these compounds? How do we know the flavor houses aren't jerking us around? Short answer, without lab testing we don't.
So, I was wondering if any of the rich members of this subreddit would take it upon themselves to send off some of the more popular recipes here to a lab to be tested. For science.
I haven't had the time to form a cogent write-up on the topic, so here are some bullet points:
-
Mustard Milk – the simple 2-flavor version – uses TFA Vanilla Bean Ice Cream, and thus contains AP. Amount details in the thread. My "nana cream homage" contains acetoin and/or acetyl propionyl from LA Banana Cream, but they do not disclose the concentration. Avoid these recipes if you don't want those molecules.
-
My retail line specifically avoids all known potentially dangerous molecules.
-
Enthalpy Labs is very unreliable. They charge $150 per sample, per chemical in question. Testing for the "3 bad chemicals" diacetyl, acetoin and acetyl propionyl would cost ~~$350~~ $450 (thanks /u/iamgr3m for pointing out my dumb mistake) per flavor. A rigorous study would include testing of each nicotine level as well. VaporShark's results note that only one sample of an undisclosed nicotine strength was tested.
-
Enthalpy claims test results can differ depending on which technician runs the test. Several vendors have sent samples from the same bottle labeled as different juices and received wildly different results.
-
Enthalpy labs is headed by one of the founders of AEMSA. There is a conflict of interest there.
-
Basically, be cautious trusting Enthalpy results as any sort of scientifically rigorous testing facility. The molecules in question are certainly concerns, but grain-of-salt as to the amounts claimed by these tests.
-
Flavorings aren't the only potential problem. Nicotine base can contain diacetyl depending on how it was produced. One method of nicotine extraction from tobacco leaves uses yeast, and diacetyl can be produced as a by-product.
-
Current testing of the un-vaporized liquid may not be a valid test. Atomizer heat affects the presence of these molecules, and I know of no current testing lab that samples the actual aerosol we inhale.
If it's $150 per chemical wouldn't it be $450 to test for all 3?
A few bullet points in response:
-
As for samples from the same bottle producing different results, how do we know it isn't a problem with the distribution of the flavor molecules in the bottle itself? In other words inconsistent mixing? Remember NN's claim about "hot spots" in their VG nic? The NudeNicotine guy (sorry forget his name) reads this sub and is a chemist, so perhaps he could chime in here about what could possibly be going on with the differing results (malice or incompetence?).
-
I would like to see Enthalpy's official response to the "differing" results claims. I would like to hear Gene Gillman himself (owner) chime in on what he thinks happened. Right now, I have only seen rumors from people like VaporChef making these claims with no real evidence that such an event occurred.
-
VaporChef sent off his liquids to another lab (not affiliated with AEMSA) and claims he got differing results from them too. Are they also in on the conspiracy?
-
If there was a conspiracy between AEMSA and Gillman to extort money from vendors (by threatening DA/AP witch hunts), why are some of the non-AEMSA vendors having their liquids test negative for DA/AP? Why are these vendors exempt from the extortion scheme?
-
I admit that if it is true that Gillman is a board member of AEMSA, then it is a conflict of interest.
-
Agree about nicotine testing. However, no one is saying that all DA/AP in liquids was added intentionally by unscrupulous vendors. I've heard interviews with Dr. Gillman and he believes some of the DA/AP is accidental (he goes into detail about the chain of custody and how flavor molecules are made. It's even possible that the flavoring manufacturers themselves aren't even aware of everything in their concentrates since they also source their raw materials from elsewhere).
-
Also agree that aerosol studies are more revealing than liquid analysis (which is limited in its usefulness).
Ultimately and unfortunately, we are probably going to have to rely on the FDA and expensive million dollar studies from universities before we get to the bottom of this. Independent labs (whether accurate or not) will always be under a veil of suspicion and accused of ulterior motives.
I should first be clear that I don't believe there's a conspiracy or extortion racket going on. I've only heard rumors, hearsay and speculation regarding the specifics of Enthalpy's political motivations. What I'm talking about here is their scientific reliability. I question their testing methods not simply because someone else has suspicion. A lab willing to certify a test result based on one sample and one test, claiming that the technician performing the test can affect the results, is not a lab I choose to trust. There are other labs (Ceutical Labs, Avomeen, GlobalLab Solutions) offering e-liquid testing now that may provide more accurate and reproducible results. The point is that purely on the available evidence, you can't trust Enthalpy regardless of what angle they're playing politically – they're bad at science.
> claiming that the technician performing the test can affect the results, is not a lab I choose to trust.
Exactly. This is either the result of poorly trained technicians or inadequate equipment. If you cannot run repeatable test, then your results are NOT reliable.
This is certainly above my pay grade, but doesn't anyone find it interesting that the house juice all came back clean? I'm not trying to wear a tinfoil hat, but considering Enthalpy's reputation amongst some major vendors and all of VS's house juice coming back clean, I can't quite invest a whole lot of faith into these results.
That's an interesting thought. Do you happen to know if they changed up recipe's anytime recently? They could have tested theirs first, fixed them up, then did the big test knowing they would come out looking good.
I have absolutely no information outside of being skeptical about the results and the lab performing the tests.

They'd be incredibly stupid to tamper with their own results: All it would take would be one person testing even just one of their in-house juices independently and contradict them to kick up a major shitstorm.
No doubt. I'm not accusing VS of anything. I think they're a decent company. I question the results and the lab that performed them.

I've always been skeptical of these studies. A couple of months ago a company opened called The Clean Vape, or something along those lines, touting lab tested juices. My first thought was that these people could have easily given VG with a fraction of the flavoring to the lab thus lowering the test results. Same deal here. The company doing the tests could easily "water down" their own juices to produce favorable results.
The bottom line is that there is less of these chemicals in the vape than in cigarettes. Good enough for me.
At this point it's going to come down to a personal choice. There very well may be a very real danger to vaping DA/AP. The results, in my opinion, are convoluted at best. If someone chooses to avoid these things then they have every right to do so. The problem is we're putting a lot of faith into a lab with a reportedly shady history being run by people tied to an organization with an equally shady history.
I'm actually in the works of trying to do this. I really want to see the levels my recipes are at. I'll only be doing my recipes, the ones I posted and the ones I currently sell. But I'm sure we can have some sort of estimate of where a certain recipe will fall within the levels. I also want to test a certain recipe for Cinnamaldehyde as this is a known toxin. This is A VERY BIG ISSUE FOR ME and I will address this more in a video to come. Testing is expensive, especially through fucking enthalpy labs, so I'm in the works of figuring out the logistics.
Also for those who aren't too familiar with the issue, those numbers that were found are extremely high and should not be taken lightly. /u/JustSayNoToDiacetyl did an amazing right up in the comment section as to why those numbers really matter. Russ had a show with Dr. Farsalino's and Dr. F stated one of the members he was speaking to said in the future it will not be called "popcorn" but rather "vaper's lung" and those numbers are a good reason to state that. I'll get back to you guys soon about the progress. It's expensive, so it'll take time.
yea this is scary. the amount of it in some of those juices is extremely high. it actually made me put my favorite flavor away which im pretty sure has some in it. only going to be vaping fruity flavors for a while sadly though im not sure all those are even safe. ill definitely be waiting for your results i feel like all flavors should have already been tested and we should have specifics at this point in the industry. vaping has been huge for few years now
Unfortunately the e-liquid vendors are saying the flavoring companies are lying, and the flavoring companies are saying the e-liquid vendors are lying. The real issue is that DA/AP just make certain flavors taste so much better, and there isn't too many options otherwise. I'm sure this issue will sort itself out, if people stop buying those juices.
> only going to be vaping fruity flavors for a while sadly though im not sure all those are even safe
Probably "safer" but for example Granny Smith Apple from TFA is no good if you want to avoid it all

I'm amazed there is so much concern about chemical additives by a group of people who burn liquids and inhale them. In 10 years from now we'll be looking back at how bad VG/PG inhalation is, let alone the additives. Let's not kid ourselves, this shit is not healthy or natural in any way.
Remember, they used to give cigarettes to pregnant women and thought that was fine.
Just sayin...
That's why I only smoked Winstons, it's the brand more doctor's recommend!
There are seriously so many chemicals in our flavors. If one of them is the magic cancer bullet it is just as likely to be one we're not even considering right now. How many different molecules go into Strawberry (Ripe) alone? If we're fucked, my money is on that one. I try to personally use DX and V2 versions when they are available, but I stopped worrying too much after it was pointed out that there is 100x more diacety in cigarette smoke.
> How many different molecules go into Strawberry (Ripe) alone?
-
Propylene Glycol 57-55-6 >= 10%

That many =P
The difference is we know DA/AP are bad, and in some rare cases, requires a lung transplant. And this is true even for people exposed just for a few months. So, we aren't talking about a lifetime of exposure here. We are talking about people in their 20's and 30's coming down with this disease. It's scary shit.
Am I saying that vaping a custard will give you popcorn lung in a few months time? No. There's no evidence of that. But we do know flavoring/popcorn/coffee/bakery workers have contracted it after a few months of exposure (some of whom were non-smokers).
There's still a lot of questions. Is the exposure from vaping the same as it is in a factory setting with airborne DA? Does powdered or liquid form make a difference? Does the heating of our atomizers make a difference or somehow break down the DA? (I haven't seen any aerosol studies that looked for DA/AP, most of them have only looked at aldehydes and metals, etc.). There's a lot of unknowns.
My only point is we should eliminate the known harmful chemicals before we start talking about the unknowns. PG/VG have been around a long, long time and used for all sorts of purposes. There have even been numerous inhalation studies on both of them showing no harmful effects (at least at acute doses -- chronic exposure might be different).
So for some reason Massdrop comes to mind. Massdrop is a site that does group buys. They also let the community suggest certain products. Prices go down as more people commit to the buy. I don't know if they'd take on a group buy like this, but something similar can be set up by us.
Essentially I see the best way to act on this is to have group buy lab testing.
It could go three ways.
-
Bulk orders for multiple flavorings simulataneously, with one extra sample purchased and sent to testing.
-
Bulk order for testing in which the community votes on which flavors to test and they split the bill.
-
People suggest flavorings and commit to paying if x number of people want that flavor tested too. Get enough people who want that, and split the costs between those interested.
While this is a sensible, and very likely solution, may I take the worst case scenario, as ask you about it? What happens if we choose number one, and it turns out there is DA/AP in worrying amounts?
Number two seems like the least likely to have this drawback, but also, less likely to be the best idea.
Number three is the idea that is so focused it might work, because people could very well have a stake in it.
I agree number three would be the way to go. If its a custom site, it could also be built to keep a searchable database of the results of each test, and the date of those tests.
