E-cigarettes most likely to affect young adults and adolescents with respiratory symptoms
E-cigarettes popularly called "e-cigs," "vapes," "e-hookahs," "vape pens," and "electronic nicotine delivery systems (ENDS) are widely in use globally. While these devices may help few people quit smoking, there is growing evidence that e-cigarettes can pose serious health risks, especially to people who do not smoke traditional cigarettes.
Electronic cigarette aerosol are reported to contain volatile aldehydes, including flavourings and oxidant metals with known pulmonary toxicity. To evaluate the associations of e-cigarette use in young adults and adolescents with symptoms of wheeze, bronchitic symptoms and shortness of breath (SOB) researchers conducted a prospective study and revealed that E-cigarette use in young adults caused high incidence of respiratory symptoms, which was independent of combustible cannabis and cigarette exposures. The study findings are published in journal BMJ Thorax.
The researchers conducted high school-based survey on tobacco products and respiratory symptoms in 2014, conducted as part of the Southern California Children's Health Study. A total of 2,097 participants completed the initial survey in 2014, with 1,609 supplying follow-up information in 2015, then 1,502 participants in 2017, and 1,637 in 2018. Mixed-effects logistic regression models evaluated associations of e-cigarette use with respiratory symptoms.
