Smoking Ban Improving Non-Smokers Health

Posted: Updated:

KENNEWICK, Wash. - In a random study of non-smokers working in restaurants and bars, researchers found levels of a byproduct of nicotine in study participants went down nearly 50 percent after smoking bans were implemented. 

Researchers took saliva samples from 2000 participants between 2003 and 2004 before and after the ban.  They found the number of cases in which they couldn't detect nicotine went up 20 percent after the ban.

The surgeon general says there's no risk-free level of second hand smoke exposure and the only way to stay safe is to continue to ban smoking indoors.
