"To have the best chance of widely replacing cigarettes, a safer alternative needs to match, or preferably surpass, that pleasure. Most people greatly prefer sweet or fruity vapes to their tobacco-flavored or flavorless counterparts." By Kiran Sidhu: filtermag.org/flavored-vapes…

Wow, thanks to you all, I'm #11 on Substack's list of Rising in Science! open.substack.com/pub/ariellesel…

My thoughts on this week's study that made the media with "a third of UK teenage vapers will go on to smoke": arielleselyaphd.substack.com/p/will-third-o…

"This study would have really benefited from preregistration because the results are a Rorschach test that can be interpreted in opposite ways to support either gateway or common liability."

There is so much wrong with this study. Arielle provides a succinct overview of the main points here:

New interview 👇 with Clearing the Air on my eye-opening moment into tobacco harm reduction, my experience in academia, and why I left. Thanks Peter Beckett !

🔎 Outstanding interview w the intrepid Arielle Selya -- describing how rigorous, accurate scientific research on vaping is systematically smothered. clearingtheair.eu/en/post/voices…

"...the comprehensive incl. of SES factors in our models eliminated sign. neg effects of early tobacco/nic use [...] which suggests an overstated neg impact of early tobacco/nicotine use on cognitive and brain measures when SES is not fully addressed." degruyterbrill.com/document/doi/1…

"...concentrations of inhaled HPHCs [harmful and potentially harmful constituents] using heated tobacco products or e-cigarettes are reduced up to 91–98%, respectively; therefore, for those who cannot quit, these could provide a less harmful alternative." mdpi.com/1660-4601/22/7…

"Among adults [aged 40+] who smoked with chronic disease [...] 27 % did not plan to ever quit. Between 2021 and 2022/23, 16 % used e-cigarettes, 14 % used NRT, 8 % used bupropion or varenicline, 3 % used nicotine pouches." sciencedirect.com/science/articl…

Martin C Arielle Selya Clearing the Air In Australia, we dont have new smokers who have never smoked but tried vaping. Instead, we have former smokers who quit smoking by using vapes. However, when the government restricted their option to vape, these individuals returned to smoking.

Martin C Arielle Selya Clearing the Air Thank you Arielle. Your article is worth reading.

One of the things I enjoy most about running Clearing the Air is the great interviews I get to do with people who have so much to teach me. Particularly enjoyed this one with Arielle Selya, who tells us how the #vaping gateway theory isn't supported by the data.

Part 8 of Roberto Sussman 's incredibly informative Substack posts on e-cigarette aerosol: "secondhand" or environmental aerosol. The key points for me (hope I understood them correctly): robertosussman.substack.com/p/a-full-guide…

Arielle Selya The text in the last paragraph should read "vaping or smoking machines can't be used to test exhaled e-cigarette aerosol because they cannot reproduce interactions of inhaled aerosol in human respiratory tracts"

Arielle Selya Key message: inhaled aerosol undergoes physical changes in humid environment in respiratory tracts, 90% of the aerosol is retained, exhaled aerosol is diluted & goes from this environment to a cold/dry one. This explains their difference.
