Based on Federal data released on Thursday and published in the CDC’s Morbidity and Mortality Weekly Report, use of e-cigarettes “tripled from 2013 to 2014” among US middle and high school students, reaching 13 percent and exceeding the percentage of those that smoke traditional cigarettes. According to the data, the number of young people using tobacco products in “some form” in 2014 rose for the first time in “years” to 4.6 million. David Muir of ABC World News (4/16, story 11, 0:15, Muir) referred to the rate increase as a “stunning number.”
