More Americans consider e-cigarettes harmful, says the study



The researchers examined data from the Tobacco Products and Risk Perceptions Survey, which was administered by the Georgia State University Tobacco Center of Regulatory Science, and the Health Information National Trends Survey, which was administered by the National Cancer Institute. Both are nationally representative surveys conducted annually by US adults.

When the results of both surveys were combined, the percentage of people who felt that e-cigarettes were less harmful than traditional cigarettes dropped from 2012 to 35 percent in 2017. The number of people using e-cigarettes At this time, the percentage of those who considered harmful to e-cigarettes was more harmful remained low in JAMA at less than 1
0%, according to the published results.

The findings "highlight the urgent need to communicate the risks of e-cigarettes to the public", the authors express concern that e-cigarettes are more harmful to cigarettes than a cigarette, but less willing to to make the transition from one to the other.

Electronic cigarettes work by heating a pure liquid called e-juice – consisting of aromas, propylene glycol, glycerin and often nicotine – until it evaporates. The resulting steam is much less offensive to both smokers and non-smokers.

The National Academy of Science, Engineering and Medicine concluded in 2017 that "e-cigarettes pose a lesser risk to an individual than flammable tobacco products."

The use of e-cigarettes with increased risk of heart attack, stroke Stanton A. Glantz, a professor at the University of California, San Francisco Center for Tobacco's Control Research and Education, said in an editorial, chronic obstructive pulmonary disease and other respiratory illnesses, at a rate similar in some cases to conventional cigarettes. which was published alongside the study by JAMA.

The vision of those who call Glantz "e-cigarette optimists" is that smokers switch completely from cigarettes to e-cigarettes. Cigarettes, he said. However, contrary to their hopes, about two-thirds of adult e-cigarette users continue to use both.

"The risks of using e-cigarettes are in addition to the risks of flammable cigarettes," he added. This means that people who use both have a higher risk of heart and lung disease than those who smoke only normal cigarettes.

As the long-term effects of the use of e-cigarettes continue to be understood, the change in public risk perception can benefit above all a group of people: adolescents and young adults.

Adolescents who have a negative attitude to e-cigarettes use them less frequently, which is important for limiting their use in this group, according to Glantz.

"In terms of overall public health impact, this explosion of youth exceeds any harm reduction that adults experience when switching from cigarettes to e-cigarettes."
