Not only does the person who vapes inhale harmful chemicals, but individuals close by in the same household are exposed as well. This is referred to as secondhand exposure. The chemicals can remain in the household for an extended period, even after the person has stopped vaping. Thirdhand exposure is also possible as the chemicals can remain on surfaces like walls, floors, carpets, curtains, and bedding.

Health problems have been identified. In one study, secondhand nicotine vape exposure was associated with increased risk of bronchitis and shortness of breath. Other research shows vaping increases air pollution in the home by increasing the number of fine particles in a room. These tiny particles are able to penetrate deep into the lungs causing not only respiratory ailments but other health issues.
