U.S. middle and high school students tripled their use of electronic cigarettes during 2014. The rate of use jumped from 4.5% to 13.4% while cigarettes fell to 9.2%. This increase has sparked concerns that nicotine exposure at these young ages may cause lasting harm to brain development and promote a switch to conventional cigarettes. Hookah, a particularly harmful method of smoking, almost doubled in the same time period.
PositiveTip: Avoid all forms of tobacco at all ages for maximum safety.
