Another Study on Flavored Vaping Products the FDA Can Ignore
Evidence continues to accumulate that non-tobacco-flavored vaping products can help reduce or discourage smoking.
The Food and Drug Administration has been particularly resistant to approving the sale of vaping products that are not flavored like cigarettes. The vast majority of the vaping products approved to date have been tobacco flavored. A small handful, approved more recently, have been menthol flavored. The thousands of marketing applications for products with other flavors have been denied. Thus, there are no FDA-permitted vaping products on the market that provide consumers with a flavor different from that provided by cigarettes.
There is a growing body of evidence that restrictions on non-tobacco-flavored vaping products can increase smoking rates, including among youth. There is also growing evidence that non-tobacco-flavored vaping products may help smokers cut back on cigarette consumption or quit. Yet the FDA has shown little interest in this research, maintaining what appears to be a de facto ban on alternative vaping flavors.
A new peer-reviewed study in Addictive Behaviors provides additional evidence of that the availability of alternative flavors can help smokers reduce or cease their cigarette consumption. In this study, smokers were given vaping products with a choice of flavors with the aim of identifying "the impact of e-cigarette flavoring choice on e-cigarette uptake and changes in cigarette smoking." And what did it find?
Compared to participants who exclusively received the tobacco flavor, participants who received any other flavor combination had greater e-cigarette uptake at the end of product provision (74 % vs. 55 %), were more likely to reduce cigarette smoking by at least 50 % at the end of product provision (34 % vs. 14 %) and at the final 6-month follow up (29 % vs. 5 %), and numerically, but not statistically, more likely to be abstinent from cigarettes at the end of product provision (11 % vs. 5 %) and the final 6-month follow-up (14 % vs. 5 %).
From the paper:
Although only a small percentage of participants exclusively selected tobacco flavored e-cigarettes, the convergence of findings across multiple outcomes in this study suggest that non-tobacco flavors may be more appealing than tobacco flavors, and may better promote uptake and reduce cigarette smoking among adults who smoke. The FDA is currently issuing PMTA [premarket tobacco product application] decisions for individual e-cigarette products, and thus far, these decisions have included many MDOs [marketing denial orders] for non-tobacco flavors based on a lack of evidence that these flavors provide a benefit to adult smokers above and beyond the benefit provided by tobacco flavors. The data presented in this secondary analysis suggest that non-tobacco flavors may indeed provide a benefit to adults beyond the benefit provided by tobacco flavors, insofar as non-tobacco flavors better promote switching away from combustible cigarettes.
While this study is limited, it provides yet more evidence that the FDA's myopic approach to vaping product flavors may be undermining efforts to further reduce smoking and its associated public health consequences. It is also further evidence that the FDA's current approach to evaluating vaping product applications, and requiring those seeking approval of non-tobacco-flavored products to demonstrate that such products provide added benefits to public health as compared to tobacco-flavored products, is quite arbitrary. (And that this approach has been adopted without any sort of notice-and-comment process in which the FDA would have to defend this policy choice is just icing on the cake.)

I wonder how fast they would play switcheroo if that tobacco settlement and all its sweet sweet continuing revenue stream were to vanish.
There is a flaw in the research -- how many neither smoked NOR vaped at the end?
The concern is that vaping is also addictive and people who would neither smoke nor vape tobacco are going to get addicted to candy flavored vapes.
About 10 years ago, there was a large vaping company that suddenly ran ads bragging how they had pulled their product from 96,000 "normal" stores. Simultaneously they put up big window signs in the remaining stores (7-11, hey, you are not "normal"!) with all kinds of warnings and so on.
This seemed odd. Was this a company "being responsible"? Or perhaps pretending to be as prophylactic to avoid regulation?
Or maybe it was tobacco setting up social cachet in an attempt to pull ruinous legislation down on vaping. "Hey, here's a functional model for vaping companies!"
Let's go see!
Yep, 50% owned by a tobacco company.
When the orange "Truth" advertising people jumped from ciggys to anti-vaping a little too quickly, I knew it was all over.
For a while there one of my (commercial supported) streaming services became basically unusable, there were so many "Truth" ads running on it. Bloody long ones, too.
The amount of money that organization was given to attack vaping was just insane.
What made it particularly annoying was knowing that the money was from the tobacco companies, to combat a market threat that was actually saving lives.
The fruit-flavored e-cigs is simple market substitution.
Think of this as akin to an alcohol market. You've got beer, wine, and hard alcohol on it. Start marketing a fruit-flavored malt beverage, and that will attract some of the beer, wine, and/or hard alcohol users over to the fruit flavored malt beverage, "lowering" the level of hard alcohol consumers. But, that is not the FDA's primary concern.
The FDA's primary concern is how the fruit-flavored e-cigs attract new, underage smokers. And that the fruit-flavored e-cigs do, overwhelmingly.
"Among youth who currently used e-cigarettes, 26.3% reported using e-cigarettes daily. The vast majority of youth who currently used e-cigarettes used flavored products (87.6%), with fruit (62.8%), candy (33.3%) and mint (25.1%) being the top three most commonly used flavors."

That's what's driving the FDA here. It's akin to having a fruit-flavored alcohol beverage marketed towards children.
Sure, but you have to take the difference in pharmacology seriously.
Alcohol is seriously toxic. We just happen to have biochemical pathways for dealing with it, because it's fairly common, and we have a long history of using it. (Groups without that long history have serious alcoholism problems, though.)
But even so, the lethal dose of alcohol is not terribly far from the recreational dose, you can accidentally drink enough to kill yourself before you get too drunk to continue drinking, if you're careless enough.
So, being worried about alcohol and children is rational, even if we take it too far.
Nicotine? Once you adjust for dosage and route of administration, it's almost indistinguishable from caffeine. The only reason we haven't treated it the same is that the plants that produce caffeine are otherwise fairly normal plants, while tobacco is a wildly toxic plant that would be unhealthy to consume even if it didn't have any nicotine in it.
But vaping separates the nicotine from the tobacco, and really isn't any more of a health threat than drinking caffeinated sodas.
There's also a bait-and-switch going on. Tobbacco is bad because of carcinogens. Nicotine is not, but it is addictive.
In a way that's happened many times elsewhere, the evil cachet switches to something else, even though it doesn't have it. The memes store an echo memory that something was bad, for some forgotten reason, and people continue thinking it bad.
Vaccines "were bad" because of mercury, which "caused autism". It didn't, but they removed it anyway. Autism didn't change. And vaccines maintained a nebulous "dangerous" cachet that continues to this day.
Not trying to start a vacccine argument, just know that process is well underway as described.
Sorry Brett,
Nicotine and Caffeine are not even in the same ballpark.
Let's start with lethal dose. The LD50 (dose at which you kill 50% of the populatoin) for Nicotine is 0.5 to 1 mg/kg (oral). The LD50 for caffeine is 100 to 200 mg/kg (oral).
Nicotine is FAR worse in terms of addictive potential and withdrawal than caffeine. It has a host of cardiovascular effects
For more, see this.
https://pmc.ncbi.nlm.nih.gov/articles/PMC4363846/
"Nicotine is one of the most toxic of all poisons and has a rapid onset of action. Apart from local actions, the target organs are the peripheral and central nervous systems. In severe poisoning, there are tremors, prostration, cyanosis, dypnoea, convulsion, progression to collapse and coma. Even death may occur from paralysis of respiratory muscles and/or central respiratory failure with a LD50 in adults of around 30-60 mg of nicotine. In children the LD50 is around 10 mg"
"Once you adjust for dosage and route of administration..."
The relevant question isn't the lethal dose, it's the ratio between the effective and lethal doses. The therapeutic index.
That's about 2 for alcohol, and 8 for nicotine. Maybe 20 for caffeine.
And of course administration by the lungs is highly addictive: Operant conditioning, the basis of the psychological component of addiction, is much more efficient when the reward is immediate rather than delayed.
So I stand by what I said: Taking into account dose and method of administration, nicotine is much more comparable to caffeine than alcohol.
Sorry Brett,
By that logic, you can take Fentanyl and Codeine and basically say "well, they're the same thing". Hell, you can probably take Fentanyl and Ibuprofin and say "well, they're more comparable than alcohol".
You DO understand that, according to your theory that it's the LD 50 that matters, not the therapeutic index, that caffeine, with an LD 50 of 150-200mg/kg, should be about 75 times more deadly than alcohol, with an LD 50 of 10-15g/kg, right?
Does that actually accord with real life experience?
No, of course it doesn't. Toxic effects from alcohol are vastly more common than from caffeine, because while they're both distributed at appropriate concentrations for recreational use, that puts alcohol much closer to the lethal dose.
So, why so many deaths from fentanyl, which has an enormous therapeutic index of 400, and thus in theory could be very safe?
BECAUSE IT'S FREAKING ILLEGAL. Hell, it being illegal is the only reason it became popular: It's so powerful that it's easy to smuggle, if it's not diluted to safe to handle concentrations.
You'd think somebody reading a blog at a libertarian site would understand that.
Two quick points:
1) We have fruit flavored alcohol. Look at the vodka shelf in your local liquor store. We also have crazy-named and various flavored malt and beer products. We don't restrict the ability of adults to consumer them.
2) That CDC data point tells us nothing about whether the existence of fruit flavors on the market increases youth consumption of vaping products. What we do know, however, is that restrictions on vaping products cause some proportion of youth to switch to cigarettes. There is now ample empirical research on this point (much of which I have blogged about).
1a) The example was meant to describe how you get a consumption shift by introducing a new product.
1b) Sales of alcohol marketed to children are not allowed by the FDA/FTC
2a) There is certainly a marketing of "fruit flavored" e-cigs to children going on For example, take a look at the following "One Mad Hit Juice Box,"
https://www.fda.gov/news-events/press-announcements/fda-ftc-take-action-against-companies-misleading-kids-e-liquids-resemble-childrens-juice-boxes
Tell me that isn't marketing to kids....
1) " That CDC data point tells us nothing about whether the existence of fruit flavors on the market increases youth consumption of vaping products"
Correlation certainly plays a role
When 90% of youths who are smoking e-cigs are using the fruit flavors, but less than 5% of OVERALL E-cig sales are the fruit flavors.
https://www.cdcfoundation.org/pr/2024/Monitoring-E-Cigarette-Trends-in-the-United-States-Report
Here is your link for % of overall sales of E-Cigs by flavor.
During the overall study period of August 2019 to April 2022, overall unit share of tobacco concept flavor e-cigarettes was 93.28 %, fruity flavored was 4.38 %, mint flavored was 0.23 %, menthol flavored was 1.48 %, and other flavors was 0.63 %
https://www.cdcfoundation.org/pr/2024/Monitoring-E-Cigarette-Trends-in-the-United-States-Report
If OVERALL sales for E-cigs are on the order of ~95% tobacco flavor....but 90% of YOUTHS are doing the "fruity flavors"...and with marketing like seen above.
It's pretty clear the fruit flavors are meant for kids.
No, that's speculation. The only thing that is clear is that kids prefer fruit flavored vapes.
Where are you getting that fruit/candy flavors are only 5% overall? The first paragraph of your link says the opposite:
Data released today in a report from the CDC Foundation and Truth Initiative reveal a 47 percent increase in e-cigarette unit sales at U.S. retail outlets* from 2019 through 2023, with flavor categories like fruit, candy, mint, menthol and desserts accounting for more than 80 percent of those sales.
1) Apologies, I linked twice, when I meant to link to a second article. That is below. Alternatively, copying and pasting the text into google would reveal the correct article.
https://www.sciencedirect.com/science/article/pii/S2211335523003972
2) Don't confuse an INCREASE in sales with the overall sales volume. As an example...
a) Company sells 10,000 units of product X in 2023. Of product X, 95% is version alpha, 5% is product beta (9500 alpha, 500 beta)
b) Company increases product X sales by 1,000 in 2024. Of those new 1,000 sales 80% are version beta, 20 percent are version alpha. (800 beta, 200 alpha). Thus, as seen 80% of the NEW SALES are product beta.
c. However, total sales volume in 2024 is 11,000 units of product. 9700 alpha, 1300 beta. (88% alpha, 12% beta). Alpha still dominates.
This link is old data, from 2019-2022, the market is very different now. Your first link does not say 80% of the *increase* was fruit/candy flavors, it says 80% of sales. This one makes it more clear that it is referring to 80% of all sales
https://truthinitiative.org/research-resources/emerging-tobacco-products/sales-flavored-e-cigarettes-continue-rise-state
You can even see for yourself, walk into any vape shop and have a look at their selection. At this point I'd say its 50/50 whether they stock any tobacco flavored vapes at all. I'm honestly surprised its as low as 80%
But the FDA banned caffeinated alcoholic beverages, e.g four locos.
https://en.wikipedia.org/wiki/Ban_on_caffeinated_alcoholic_drinks_in_the_United_States
Telling us what youths who use e-cigarettes do tells us nothing about whether e-cigarettes cause youths to start smoking.
Those studies exist as well.
Youths who use e-cigs are seven times more likely to use normal cigarettes one year later when compared to those who did not use an e-cig.
https://www.sciencedirect.com/science/article/abs/pii/S0306460320307231?dgcid=author
Now you might argue that...well, that's just correlation, not causation. But remember, people who smoke cigarettes are 15 - 30 times more likely to get lung cancer than those who don't smoke. Can you absolutely GUARANTEE that those who smoke will get lung cancer? No. But....enough correlation in one place starts to make a good case....
Industry wants to give us choices; the government wants to take away all choices.

The article points out that non-tobacco-flavored vaping products could help smokers quit or reduce smoking, yet the FDA continues to block these options. A new study adds to the growing evidence that flavored vaping is more effective than tobacco-flavored options, but the FDA’s restrictive policies and lack of transparency seem to work against public health goals. It’s time for a rethink.
