New Study Released On Secondhand Smoke

Posted: Updated:

ALANTA - Less people are breathing in secondhand smoke. A new study shows the number of people subjected to secondhand smoke has drastically declined since the early 1990's.

The Centers for Disease Control and Prevention say one reason is laws, like the State of Washington's, that ban smoking in public places.

Recent tests found 38 percent fewer non-smokers with signs of nicotine in their blood, compared to non-smokers in the late 80's and early 90's.
