Teens Exposed to Secondhand Smoke

A new study by the CDC shows more than half of middle and high school students in the US are exposed to secondhand smoke. Researchers say the findings are alarming, because the exposure can impact their lung and cardiovascular health, and it is completely preventable. The study took data from a survey, in which many students said they had never used tobacco, but were exposed to smoke in restaurants, parks, at work and at home. Research shows children who are exposed to the secondhand smoke are at increased risk of asthma and lung infections. Researchers say there is some evidence that the exposure to nicotine primes their brains and makes them more likely to be addicted to nicotine in the future.
