New studies for UK, Netherlands and Flanders and US confirm gateway effects of e-cigs to combusted tobacco products

Three new studies add to the already overwhelming case that e-cigarettes are a gateway to combusted product use; two of these studies also show that combusted tobacco use predicts later e-cigarette use among youth. These studies are benefit from the fact that the data were collected relatively recently, which is important because e-cigarette technology isContinue reading “New studies for UK, Netherlands and Flanders and US confirm gateway effects of e-cigs to combusted tobacco products”

More details on how menthol helps Big Tobacco keep kids hooked

US Preventive Services Task Force finds evidence on e-cigs as a medicine for quitting “insufficient”

I have written several times about the differences between e-cigarettes as a consumer product and as a cessation medicine. pointing out that population observational studies are relevant for e-cigarettes as a consumer product and randomized clinical trials (RCTs) are relevant for e-cigarettes as a smoking cessation therapy. Now the US Preventive Services Task Force, aContinue reading “US Preventive Services Task Force finds evidence on e-cigs as a medicine for quitting “insufficient””

Youth e-cig use triples likelihood of daily cig smoking

The evidence that e-cigarettes are a gateway for smoking is strong and consistent. Now John Pierce and his colleagues have made that connection even stronger by showing that e-cigarette use strongly predicts daily cigarette smoking. (Previous studies measured current cigarette smoking, meaning in the past 30 days.) Their paper, “Use of E-cigarettes and Other TobaccoContinue reading “Youth e-cig use triples likelihood of daily cig smoking”
