Over one-third of U.S. kids are exposed to secondhand smoke  

New data from the CDC suggest that over a third of children between the ages of 3-17 are exposed to secondhand smoke from cigarettes. Here’s more from the report, which looked at blood levels of cotinine, a byproduct of nicotine:

• Overall findings: Between 2013-2016, some 35% of kids were exposed to secondhand smoke, but that varied by race. More than 60% of black children were exposed, compared to around a quarter of Hispanic youth. 
• By age and sex: More kids under the age of 11 were exposed to secondhand smoke than older children. Boys and girls were exposed at similar rates. 
• Other trends: More than half of children from families living below the federal poverty level were exposed to cigarette smoke. The same was true for nearly 81% of children who lived with two or more smokers at home.
