Dual cigarette and e-cig use increases human risk of lung cancer 40 times

As summarized in an earlier blog post, exposure to e-cigarette aerosol accelerates tumore growth and spread (metastasis) among established cancers. This effect is distinct from actually causing the cancer (i.e., carcinogenesis). Indeed, propylene glycol and vegetable glycerine (PG/VG), the primary solvents in e-liquid and which have been assumed to be inert are major causes ofContinue reading “Dual cigarette and e-cig use increases human risk of lung cancer 40 times”

E-cig advocates publish results showing e-cig users have more respiratory symptoms than nonsmokers

E-cigarette advocate Riccardo Polosa, along with pro-harm reduction colleagues from around the world, recently published Respiratory symptoms among e-cigarette users without an established smoking history in the VERITAS cohort. Their paper presents strong evidence that sole e-cigarette users (i.e., people who are not also smoking cigarettes) are significantly more likely to experience respiratory symptoms thanContinue reading “E-cig advocates publish results showing e-cig users have more respiratory symptoms than nonsmokers”

FDA & NIH must support research to increase tobacco cessation reach and engagement to address populations disproportionately harmed by Big Tobacco

My colleagues and I submitted this public commento to FDA and NIH regarding their priorities for tobacco cessatio research. The Regulations.gov tracking number is m3p-2qiq-zm6w. A PDF version is available here. While it was not publicly available when we were preparing this comment, a lot of the suggestions overlap or complement the recently-released Surgeon GeneralContinue reading “FDA & NIH must support research to increase tobacco cessation reach and engagement to address populations disproportionately harmed by Big Tobacco”

New Surgeon General Report highlights how tobacco industry promotes health disparities, supports menthol and flavor bans and highlights cannabis crossover

Surgeon General Vivek Murthy just released a new Surgeon Genera Report, “Eliminating Tobacco-Related Disease and Death: Addressing Disparities—A Report of the Surgeon General” (Press release). Surgeon General Reports, which, like this one, often take years to complete, represent the broad (if cautious) consensus on a scientific topic. Hundreds of people are involved in drafting, reviewing,Continue reading “New Surgeon General Report highlights how tobacco industry promotes health disparities, supports menthol and flavor bans and highlights cannabis crossover”

Secondhand cannabis and tobacco smoke both increase cancer risk

The pro-cannabis advocacy group California NORML recently reported that it had successfully kept an exemption for cannabis use in the smokefree multiunit housing provision of the draft ordinance that the Oakland City Council approved on first reading on November 12, 2024.  Their posting includes two inaccurate statements dismissing the cancer risks of secondhand cannabis andContinue reading “Secondhand cannabis and tobacco smoke both increase cancer risk”

Oakland City Council should advance law making bar patios smoke-free and make multi-unit housing tobacco and cannabis smoke-free at November 12 hearing

On November 12, the Oakland City Council will hold a public hearing on a proposed Oakland Smoke-Free Bar Patios and Smoke-Free Multi-Unit Housing Ordinance introduced by Councilperson Dan Kalb.  The ordinance as proposed would close a loophole that allows smoking on outdoor bar patios and also make multi-unit housing tobacco smoke-free.  Unfortunately, the current draft ordinanceContinue reading “Oakland City Council should advance law making bar patios smoke-free and make multi-unit housing tobacco and cannabis smoke-free at November 12 hearing”

Canadian health groups should press for rejection of proposed provincial tobacco litigation settlement

On October 17, 2024, the proposed terms for settlement of longstanding provincial litigation against the tobacco industry were made public. It is probably the worst settlement of tobacco litigation anywhere in the world to date. All it does is provides one-time money for the provinces to reimburse them for some of the medical costs incurredContinue reading “Canadian health groups should press for rejection of proposed provincial tobacco litigation settlement”

The RCP got this right: Promotion of tobacco harm reduction is playing right into the tobacco industry’s hands

I previously published three detailed critiques of the 2024 UK Royal College of Physicians report E-cigarettes and Harm Reduction: An Evidence Review for being an incomplete and selective review of the literature in three areas — underestimating the magnitude of disease risk caused by e-cigarettes, ignoring the large body of real world evidence that e-cigarettesContinue reading “The RCP got this right: Promotion of tobacco harm reduction is playing right into the tobacco industry’s hands”

Smokers who use e-cigs as for smoking cessation are more likely to end up dual users than to “switch completely” or stop smoking and vaping

E-cigarette enthusiasts, including the FDA and the NHS and others in England, and some in New Zealand and Canadian governments continue to promote “switching completely” from cigarettes to e-cigarettes as a form of harm reduction. I just found another paper that shows that the reality is that adult smokers who use e-cigarettes as a smokingContinue reading “Smokers who use e-cigs as for smoking cessation are more likely to end up dual users than to “switch completely” or stop smoking and vaping”

Longtime tobacco control leader Neil Collishaw dies

I was saddened to hear that Neil Collishaw succumbed to small cell bladder cancer on October 10, 2024. Neil shared the news of his diagnosis friends and colleagues in early 2023, but continued contributing good ideas and feedback to tobacco control activities until near the end. For most of his career Neil epitomized the soft-spokenContinue reading “Longtime tobacco control leader Neil Collishaw dies”
