This is certainly a good thing for the multinational tobacco companies that invented ecigs in the 1990s (pubmed.ncbi.nlm.nih.gov/27852893/). Not so good for the people who are addicted to them (publications.aap.org/pediatrics/a...).

The question is: "De e-cigs actually reduce harm?" The answer is NO even if you only consider adults. Why? They don't help people quit in the real word and instead promote dual use, which is more dangerous than smoking.

I'm still waiting for you to engage the actual evidence as it exists today.

Did you actually carefully read the statement and the references? What are the specific errors? It seems to me that you selectively quote (mostly old) things that support your predetermined position and ignore or discount the more recent evidence that does not support your position.

I see that, but I don't believe an IPA statement is oracular omniscient truth. Seven years in tobacco control have taught me to question everything.

At a minimum, we must both admit that well-meaning experts now disagree. And I KNOW how ironic that is: Claiming "experts disagree..."

The issue is not supporting harm reduction as an abstract idea, but whether e-cigs reduce harm. The new IPA statement concludes, "e-cigarettes are not an effective harm reduction strategy for adults and pose a serious risk to nicotine-naïve youth." Details at publications.aap.org/pediatrics/a...

International Pediatric Association publishes position paper concluding that “e-cigarettes are not an effective harm reduction strategy for adults and pose a serious risk to nicotine naïve youth”

On October 10, 2025, the International Pediatric Association (IPA) published a landmark position paper, “E-Cigarettes and the Nicotine Epidemic: Statement From the International Pediatric Association,” in Pediatrics, the international peer-reviewed journal published by the American Academy of Pediatrics. The paper concluded, “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.”

This argument is a distraction. As of Oct 2023 there were 11 epi studies of ecigs and heart disease (not counting the retracted paper) that show a statistically significant increase in risk (OR 1.24; 95% CI 1.05-1.46). And lots of clinical and biology studies on why. profglantz.com/2023/05/05/t...

Yes, a campaign by ecig advocates did succeed in getting one of my papers retracted. For details on that in the context of ongoing industry efforts to attack my work and counter science generally, see the oral history UC published on me: digicoll.lib.berkeley.edu/record/267781 (PDF pages 248-268).

This comment ignores the fact that studies that follow the same kids forward in time (longitudinal studies) consistently find a gateway effect. See profglantz.com/2025/08/26/t... If ecigs were just substituting for cigs, youth ecigs would not have increased way more than smoking dropped.

FDA has scheduled a virtual meeting of its Tobacco Products Scientific Advisory Committee (TPSAC) meeting for October 7, 2025, to discuss the modified risk tobacco product (MRTP) renewal applications submitted by Philip Morris Products S.A. for several IQOS heated tobacco products that is happening despite the government shutdown. (Participants can attend via a live webcast.) This meeting is required by law if FDA is to move forward on allowing Philip Morris to continue to make reduced exposure claims about IQOS.

Archived copy of Tobaccoscam website and ads on smokefree hospitality is available

In 2002 I developed an educational campaign called Tobacco Scam designed to counter tobacco industry propaganda directed at restaurants and to expose the industry’s cooptation of the state and national restaurant associations. It was called “Tobacco Scam” because it highlighted how the tobacco companies were scamming restaurants and bars into opposing smokefree laws based on bogus claims that such laws were bad for business and convincing them to install expensive ventilation systems that did not actually eliminate secondhand smoke.

Inhaled cannabis associated with increased risk of asthma and COPD independent of tobacco smoking

Answering the question of whether inhaling cannabis increases the risks of asthma and chronic obstructive pulmonary disease (COPD) has been complicated by the fact that in the past almost all cannabis smokers also smoked tobacco, so it was difficult to determine whether the observed associations between smoking cannabis and these diseases was really due to their tobacco use (confounding…

Archival copies of Smokefree Movies and Smokefree Media websites are available

I ran the Smokefree Movies campaign from 2001 through my retirement from UCSF in 2020. This education/advocacy campaign put pressure on the motion picture industry to stop promoting tobacco to young audiences through specific policy changes. We advocated for these policies though paid advertising in the trade and general press and the Smokefree Movies website. We website also used data collected by Breathe California to report which films did and did not have smoking every week and who was responsible for the smoking.

You have ignored the information in the papers I sent you about WHO is vaping and that ecigs expanded the epidemic.

Until you stop just repeating your (incomplete) arguments and engage those details it is not worth continuing this conversation.

There are 3 ways to portray these changes:

DISHONEST: Smoking dropped, BUT vaping increased
ACCURATE: Smoking dropped in association with
increased vaping
PLAUSIBLE: Smoking dropped BECAUSE vaping increased

The 1st denies product substitution is plausible.

This is a great example of cherry picking data to give a misleading picture. Few kids are daily e-cig users or smokers. Setting a daily use standard radically understates the level of addiction. As ecigs have got more addictive, however, days used has increased. pubmed.ncbi.nlm.nih.gov/36342713/

By whom, specifically?

Yes, gateway and common liability are separate things. Lots of evidence gateway is real and common liability cannot explain all youth initiation. The papers I cited (separately) go into detail on both issues.
