电子烟真的安全吗？

近年来,电子香烟以"更健康,更便宜的传统香烟替代品"形象出现在公众面前,生产商称这种产品不燃烧,让旁人无需忍受难闻的气味.然而美国ABC新闻的一篇报道称,电子烟也会让你身边的人受到伤害. Electronic cigarettes are supposedly a safer alternative to conventional cigarettes. But they may actually pose a serious danger to others in your home — particularly children. The U.S. Centers for Disease Control and Prevention warned in report released recently that the number of phone calls to U.S. poison control centers related to e-cigarette use has increased from just one call per month on average in 2010 to nearly 200 calls per month in early 2014. Report author Dr. Kevin Chatham-Stephen, a pediatrician and an epidemiologist with the CDC said that though e-cigs comprise less than 2 percent of all tobacco-related sales, they now account for more than 40 percent of poison center calls. More than half of the calls involved children younger than 5 years old. alternative=选择 conventional=传统的 pediatrician=儿科医生 epidemiologist=流行病医生
