Exposure to the liquid nicotine solutions in electronic cigarettes (e-cigs) may be dangerous because they are highly concentrated. Little is known about the impact of exposure on public health. This study describes e-cig exposures reported to poison centers. ⋯ E-cig exposures reported to poison centers are increasing. Most of the patients are young children, and the exposures most frequently occur through ingestion. Reported exposures often do not have serious outcomes.

Electronic cigarette (e-cigarette) marketing has increased considerably since the product entered the US market in 2007, thereby warranting additional surveillance to monitor recent trends in population-level awareness and utilization. We assessed the prevalence, characteristics, and trends in e-cigarette awareness and use among nationally representative samples of US adults during 2010-2013. ⋯ Awareness and use of e-cigarettes increased considerably among US adults during 2010-2013. In 2013, more than one-third of current cigarette smokers reported having ever used e-cigarettes. Given the uncertain public health impact of e-cigarettes, continued surveillance of emerging use patterns is critical for public health planning.

Electronic cigarette (e-cigarette) use is increasing rapidly, and the impact on youth is unknown. We assessed associations between e-cigarette use and smoking intentions among US youth who had never smoked conventional cigarettes. ⋯ In 2013, more than a quarter million never-smoking youth used e-cigarettes. E-cigarette use is associated with increased intentions to smoke cigarettes, and enhanced prevention efforts for youth are important for all forms of tobacco, including e-cigarettes.
