In brief: Second hand smoke

Yes. The U.
S. Environmental protection agency, the U.S. National toxicology program, the U.S. Surgeon general, and the international agency for research on cancer have all classified secondhand smoke as a known human carcinogen (a cancer-causing agent).People who live in a big city for 10 or more years have a slightly higher risk of lung cancer. This is most likely to pollutants like car exhaust.
