Report: Secondhand smoke bad at any level
June 27, 2006There is no safe level of how much exposure a person has to secondhand tobacco smoke, the U.S. Surgeon General said in a report issued Tuesday.
In "The Health Consequences of Involuntary Exposure to Tobacco Smoke," Dr. Richard Carmona said even brief secondhand smoke exposure can cause immediate harm, including a 25 percent to 30 percent increase in risk of heart disease and a 20 percent to 30 percent increase in lung cancer risk in non-smoking adults.
The report said the findings are of major public health concern as nearly half of all non-smoking Americans are still regularly exposed to secondhand smoke.
However, Carmona noted progress in monitored levels of cotinine, a biological marker for secondhand smoke exposure, which have fallen in non-smokers by 70 percent since the late 1980s.
"Smoke-free indoor environments are proven, simple approaches that prevent exposure and harm," Carmona wrote.
