second hand smoke
Secondhand smoke is the combination of smoke from the burning end of a tobacco product and the smoke breathed out by the user. Secondhand smoke contains more than 7,000 chemicals; hundreds are toxic, and about 70 can cause cancer. There is no risk-free level of secondhand smoke, and even brief exposure can cause immediate harm.
