I don't buy into second hand smoke...
You have GOT to be kidding me. Never seen those 2nd-hand smoke commercials? I can't believe I've encountered so many people who don't buy into second hand smoke, it's bewildering.
“Despite the much lower dose that nonsmokers receive compared to smokers, secondhand smoke can have effects nearly as significant as active smoking,” said study author Stanton A. Glantz, Ph.D., a professor of medicine at the University of California, San Francisco.
“Even a little secondhand smoke is dangerous. The effects on blood, blood vessels and heart rhythm occur quickly, often within minutes.”
said Joaquin Barnoya, M.D.

More than 4,000 chemicals have been identified in mainstream tobacco smoke; however, the actual number may be more than 100,000 (1). Of the chemicals identified in secondhand smoke, at least 60 are carcinogens (substances that cause cancer), such as formaldehyde. Six others are substances that interfere with normal cell development, such as nicotine and carbon monoxide
In
1993, the U.S. Environmental Protection Agency (EPA) determined that there is sufficient evidence that secondhand smoke causes cancer in humans and classified it as a Group A carcinogen (2, 6).
Approximately 3,000 lung cancer deaths occur each year among adult nonsmokers in the United States as a result of exposure to secondhand smoke
