TUESDAY, May 15, 2018 (HealthDay News) – Many people are trying e-cigarettes, but not everyone is staying with them, a new poll finds.
E-cigarettes containing nicotine have been marketed as a way to help tobacco smokers quit smoking and as an alternative to cigarettes. Although the number of US adults they tried between 2014 and 2016 rose sharply, researchers said they found out.
"The decline in current use, but the increase in those who have tried e-cigarettes, might suggest this. Some people are trying to stop using e-cigarettes," said lead researcher. Wei Bao. He is assistant professor of epidemiology at the University of Iowa.
However, it might be too early to draw data on e-cigarette trends from just three years, he added.
"E-cigarette consumption among US adults is changing over time," said Bao. "To understand the health effects of changes in the use of e-cigarettes requires continuous monitoring."
To gauge the changes, Bao and his colleagues used data from the US National Health Interview Survey from 201
Bao's team collected data on more than 100,000 men and women after their use of E-cigarettes, also called "steaming", were asked.
The number of people testing e-cigarettes rose by nearly 13 percent in 2014, 14 percent in 2015 and 15 percent in 2016, the researchers found.
But over the same period, the number of those who still consume e-cigarettes fell by 3.7 percent in 2014, by 3.5 percent in 2015, and by 3.2 percent in 2016.
The decline was significant in adults over the age of 65. Women, whites, low-earners and those who smoked normal cigarettes showed the results.
However, the use of e-cigarettes has increased among former smokers and adults who have never smoked, Bao said.
Greg Conley, president of the American Vaping Association, believes the findings provide evidence that e-cigarettes help people quit smoking.
"This study should give great rest to those who have used shabby science." He said.
According to Conley, more than 2.6 million ex-smokers are vaping.
"This is equivalent to hundreds of millions of packs of cigarettes that are not smoked each year, which would be even higher, but for the relentless Campai" misleading the public about steam products, "Conley said.
A specialist who researched e-cigarettes did not agree.
"It is good that the use of e-cigarettes is gradually waning," said Stanton Glantz, a professor of medicine at the University of California, San Francisco's tobacco control center , Research and Education
But, "The net effect that e-cigarettes have is supposed to keep people smoking cigarettes," said Glantz.
The increase in e-cigarette use among former smokers and those who have never smoked "It's just the widening of the tobacco epidemic," he said.
Glantz also asks if e-cigarettes help people quit smoking. " Most people make e-cigarettes harder to stop smoking, "he said.
Some people have used e-cigarettes and successfully given up tobacco. But among all adults who try to quit, using e-cigarettes makes it 20 percent less likely that they will stop compared to those who do not use them, Glantz said.
"So while they help promote smoking cessation, they actually make it harder to quit smoking," he said.
E-cigarettes are also popular with many young people, leading health experts fear that the devices could create a new generation of smokers.
The report was published on May 15 in the Journal of the American Medical Association .
