The only way to fully protect people who don't smoke from SHS indoors is to prohibit all smoking in that indoor space or building. Separating those who smoke from those who don't, cleaning the air, and ventilating buildings cannot keep people who don't smoke from being exposed to SHS. Many US local and state governments, and even federal governments in some other countries, have decided that protecting the health of employees and others in public places is of the utmost importance and have passed clean indoor air laws.

For instance, some of the carcinogens that are known to cause lung cancer have been found in dust samples taken from the homes of people who smoke. Research has also shown that thirdhand smoke can damage human DNA in cell cultures and might increase lung cancer risk in lab animals.
Still, the compounds may be stirred up and inhaled with other house dust, and may also be accidentally taken in through the mouth.
Because of this, any risk the compounds pose is probably greater for babies and children who play on the floor and often put things in their mouths. As e-cigarettes and similar devices have become more popular in recent years, a growing concern is whether the aerosol of tiny particles exhaled by users, sometimes referred to as secondhand vapor , is harmful to other people who breathe it in.
Scientists are still learning about the health effects of being exposed to secondhand e-cigarette aerosol. However, the US Surgeon General has concluded that e-cigarette aerosol is not harmless.
