Anti-smoking groups frequently make the statement that Second Hand Smoke contains over 4000 chemicals. I have researched this argument using materials provided by the Boone County Coalition for Tobacco Concerns to the Columbia Boone County Board of Health.
Below is a page from the materials the BCCTC provided to the Board of Health regarding chemicals in second hand smoke. At first glance it looks pretty scary with all those chemical names and big numbers.
But what does it really mean? How can a decision maker determine from the page below what the health risks might be and whether those risks warrants implementation of a smoking ban?
There are a number of flaws with this document which makes it of little value as a basis for making a decision.
1. Amount (mg) values 1000 times larger than actual
2. Chemicals are listed with an Amount (mg) of "No Data"
3. There is no context for determining the health risk
4. Federal agency responsible for worker safety decided that Second Hand Smoke should not be regulated
The page above was included in the materials provided by the BCCTC to the Board of Health. The page was scanned and its reproduction on our site is allowed by Copyright Fair Use.
