Vaping habits may be dipping but non-smoking advocates urge action

More adults may be giving e-cigarettes a try, but fewer people are making it a habit, according to research published in Journal of the American Medical Association Tuesday.

Why it matters: E-cigarettes often contain the addictive ingredient nicotine and other substances that the Surgeon General says may be dangerous, particularly to young people. Non-smoking advocates say the prevalence drop is encouraging, but the government still needs to mandate further research and curb teenage usage.
