Research from The Johns Hopkins University on vape ingredients published in October 2021 reveals thousands of chemical ingredients in vape products, most of which are not yet identified. Among those the team could identify were several potentially harmful substances, including caffeine, three chemicals never previously found in e-cigarettes, a pesticide and two flavorings linked with possible toxic effects and respiratory irritation. A 2021 study found that daily e-cigarette usage among tobacco smokers can increase the likelihood of quitting smoking by eightfold. Researchers assessed data from the 2014–2019 Population Assessment of Tobacco and Health study, focusing on smokers who were not planning to quit smoking at the start of the period.
We have previously found different results when using male versus female mice in our inhalant exposure experiments, and typically run one sex followed by the other (to prevent inter-mixing during the 3-times daily exposures). We have added further discussion regarding this limitation into the discussion. We do plan on running JUUL exposures in male mice, but these will be limited to Tobacco and Menthol flavors since these are currently the only ones available on the market.
Bugged by vaping
Gilbert said in 2013 that today’s electric cigarettes follow the basic design set forth in his original patent. In one of the few studies identified, a 2015 survey of 316 pregnant women in a Maryland clinic found that the majority had heard of e-cigarettes, 13% had used them, and 0.6% were current daily users. These findings are of concern because the dose of nicotine delivered by e-cigarettes can be as high or higher than that delivered by traditional cigarettes. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank.
No research is available to provide details on the efficacy of vaping for quitting smoking during pregnancy. There is robust evidence that vaping is not effective for quitting smoking among adolescents. In view of the shortage of evidence, vaping is not recommend for cancer patients, although for all patients vaping is likely less dangerous than smoking cigarettes. The effectiveness of vaping for quitting smoking among vulnerable groups is uncertain. Most young e-cigarette users have never smoked, but there is a substantial minority who both vape and smoke.
In Canada, e-cigarettes had an estimated value of 140 million CAD in 2015. A 2014 audit of retailers in four Canadian cities found that 94% of grocery stores, convenience stores, and tobacconist shops which sold e-cigarettes sold nicotine-free varieties only, while all vape shops stocked at least one nicotine-containing product. The number of e-cigarettes sold increased every year from 2003 to 2014. As of January 2018, the growth in usage in the UK has slowed down since 2013. น้ำยาบุหรี่ไฟฟ้า pod -cigarette sales could exceed traditional cigarette sales by 2023.
