Passive smoking is harmful, no need to remind you. But what about the passivity induced by the use of the e-cigarette?
On January 10, the magazine BMJ Thorax relayed the conclusions of a study conducted over many years (from 2014 to 2019) by researchers at the University of Southern California in Los Angeles.
At the start, a fairly simple observation: “Little is currently known about the health effects of nicotine exposure from vaping”.
A cohort of high school students
To better study the effects of vpassive potting, 2,097 high school students had to provide information on their respiratory health, exposure to electronic cigarette but also to tobacco and cannabis smoke in the context of research baptized “Southern California Children Health Study”.
Results? The prevalence of exposure to these vapors increased on average from 11.7% to 15.6% during this period. The researchers further detail: “The prevalence of wheezing, bronchial lesions and shortness of breath decreased from 12.3% to 14.9%, 19.4% to 26% and 16.5% to 18.1% respectively. , during the study period”.
A call for another regulation
For the researchers, therefore, young adults who had been exposed to the vapors of cigarette electronics were more likely to develop respiratory problems than participants who had never been exposed.
They conclude, remaining cautious: “If this is a causal link, reducing exposure to e-cigarette vapor in the home would reduce the occurrence of respiratory symptoms and provide a compelling rationale for regulating the use of e-cigarettes. e-cigarettes in public places”. The link of cause and effect should, according to them, be demonstrated in subsequent work.
