HCR Update from Mark Sanna: The case for regulating electronic cigarettes grew even stronger this month when the Centers for Disease Control and Prevention reported a notable increase in their use by high school and middle school students. A national survey found that the percentage of high school students who had ever smoked e-cigarettes jumped to 10% in 2012 from 4.7 percent in 2011; for middle school students (grades six to eight), the figure rose to 2.7% from 1.4%.
