This study is the first to report changes in awareness and use of e-cigarettes between 2010 and 2011.
During 2010–2011, adults who have used e-cigarettes increased among both sexes, non-Hispanic Whites, those aged 45–54 years, those living in the South, and current and former smokers and current and former smokers. In both 2010 and 2011, e-cigarette use was significantly higher among current smokers compared to both former and never smokers. Awareness of e-cigarettes rose from about four in 10 adults in 2010 to six in 10 adults in 2011.
“E-cigarette use is growing rapidly,” said CDC Director Tom Frieden, MD, MPH. “There is still a lot we don’t know about these products, including whether they will decrease or increase use of traditional cigarettes.”
Although e-cigarettes appear to have far fewer of the toxins found in smoke compared to traditional cigarettes, the impact of e-cigarettes on long-term health must be studied. Research is needed to assess how e-cigarette marketing could impact initiation and use of traditional cigarettes, particularly among young people.
“If large numbers of adult smokers become users of both traditional cigarettes and e-cigarettes — rather than using e-cigarettes to quit cigarettes completely — the net public health effect could be quite negative,” said Tim McAfee, MD MPH, director of the Office on Smoking and Health at CDC.
