Roughly 10.8 million US adults use electronic cigarettes, and more than half of them are under 35 years old, according to a story at reuters.com citing the results of a study.
One in three e-cigarette users vape daily, researchers report in the Annals of Internal Medicine.
“Electronic cigarette use is also closely associated with other high-risk behaviors,” said senior study author Dr. Michael Blaha, director of clinical research for the Baltimore-based Johns Hopkins Ciccarone Center for the Prevention of Heart Disease.
“The most common pattern of use in the US is dual use, i.e. current use of both traditional cigarettes and electronic cigarettes.”
The study found that 20-somethings, smokers of traditional cigarettes, unemployed adults, and people who identify as lesbian, bisexual, gay, and transgender (LGBT) are more likely than other individuals to use e-cigarettes, the study also found.
“It is becoming clear that specific vulnerable groups are at highest risk of adopting electronic cigarettes,” Blaha said by email.
The Reuters story said that a limitation, however, was that all the data was self-reported and not verified by medical records.
And researchers didn’t know the type of e-cigarette devices people used or the liquids they vaped.
