The citations are in the paper. (I would have thought that you would have read the paper carefully before criticizing it.) You can read it for free at evidence.nejm.org/doi/full/10....

Garner's statement that I believe "most smokers who take up vaping remain dual users" shows that he never bothered to carefully read our paper. We state, based on most recent data at the time, that 39.1% of US and 66.7% of Swedish vapers are dual users.

I have had a kind respectful back-and-forth with @profglantz on BSKY. I can't speak for him...

...but I believe his argument for e-cigarette harm is based on (a) his belief that most smokers who take up vaping remain dual users and (b) evidence that dual use is more harmful than exclusive smoking.

Every ecig paper I saw at the TOPS lectures I attended made the (often unstated) assumption that they reduce harm. Also, I applied to present our NEJM-E paper and you said "no" because I was retired. I think you & your committee are afraid of data that questioned your assumptions.

I wish I could claim ownership of TOPS, but it isn't mine. I'm one of five on the Executive Board; everybody has equal say. We prioritize high-quality research and our program shows good balance across a variety of dimensions. We are happy to consider any work submitted by a qualifying researcher.

Even activist anti vapers like Emeritus Professor Simon Chapman AO admit vaping is much less harmful than combustible cigarettes. Why can’t @profglantz.com admit what has been acknowledged by reputable researchers again & again? @chancethegardener.bsky.social

Actually, these calculations apply at the level of individual smokers, not the population. Population estimates would have to include all the kids addicted to nicotine with ecigs, which would make the picture even worse.

That's just not correct. Look at ipa-world.org/page.php?id=.... I also offered to present our meta-analysis of ecigs and actual disease (based on 107 studies profglantz.com/2024/02/27/e...) to your TOPS seminar, but you didn't want to hear it. Happy to got through it with you privately.

While there is some substitution, the RCTs show that for every switcher there are 2-4 dual users. Dual use is more dangerous than just smoking.

If I changed the labels on this graph to "sales of electric cars" (GREEN LINE) vs. "sales of combustion engine cars" (RED LINE), no one would question what is happening.

Old school tobacco control experts refuse to admit even the remote possibility that product substitution is happening.

E-cigarettes increase harm to smokers, so should not be promoted as a harm reduction strategy (in 10 slides)
The tobacco industry has used claims of reduced harm to sell its products since the 1950s with its efforts to promote “safe cigarettes.” “Harm reduction” claims have been central to marketing of e-cigarettes since they were commercialized in 2003. The tobacco industry and its allies continue to use claims of reduced harm to argue against applying strong tobacco control policies to e-cigarettes and other noncombusted tobacco products.

Raising the cost of a pack of cigarettes, whether because of taxes or price hikes, has long been associated with lower consumption. The new paper Differential Responsiveness to Cigarette Prices by U.S. Adults Who Do and Do Not Use Cannabis by Tingting Yao and her UCSF colleagues shows that cigarette smokers who currently use cannabis are twice as likely to reduce the number of cigarettes they smoked per day than cigarette smokers who do not currently use cannabis.

She probably is not familiar with the latest science. Things are accumulating very quickly. Her blog post nida.nih.gov/about-nida/n... does NOT discuss the meta-analyses of e-cig association with disease. (Reposted with key correction.)

The oligarchy wants full control of what we watch and read.
A tweet from Robert Reich states: “The richest man on earth owns X. The second richest man on earth is about to acquire TikTok and his family could soon own both Paramount and Warner Bros. The third richest man owns Facebook, Instagram, and WhatsApp. The fourth richest man owns The Washington Post. See the problem here?”

Ecig enthusiasts acting more and more like tobacco and global warming deniers
Reflecting on the problems with the paper E-Cigarettes in Historical Context—Innovation, Risk, and Regulation by Michael Pesko, Jamie Hartmann-Boyce, Rachel Fung and Neal Benowitz reminded me that, as the evidence continues to pile up that e-cigarettes increase harm for both adults and youth, e-cigarette enthusiasts are moving beyond legitimate scientific differences of opinion and acting more like the tobacco industry or global warming deniers, including systematically ignoring or disqualifying inconvenient evidence.

No. The 2018 NASEM report was an excellent summary of the evidence 7 years ago when it was published, but it is now badly out of date. Almost all the evidence linking ecigs to disease showing the quote you cite is wrong was published after 2018. See profglantz.com/2025/10/21/n... for more details.

New Pesko et al paper supporting e-cigs ignores current science
Several people have asked me what I thought of the just-published paper E-Cigarettes in Historical Context—Innovation, Risk, and Regulation by Michael Pesko, Jamie Hartmann-Boyce, Rachel Fung and Neal Benowitz. Like other similar papers published by some of these people, the Pesko paper relies on the 7 year old 2018 National Academies of Science, Engineering and Medicine report to conclude that ecigs are much safer than cigarettes.

Reducing death is a good goal, but ecigs don't accomplish it. New IPA report concludes, “In contrast to early hopes and assumptions, e-cigarettes are not an effective harm reduction strategy for adults and pose a serious risk to nicotine-naive youth.” ipa-world.org/page.php?id=...
