285 Copyright Goodheart-Willcox Co., Inc. Chapter 9 Tobacco and Vaping classroom or at school-sponsored events may face disciplinary actions and even suspension. In communities, young people can also face legal consequences for using tobacco products in public places, such as restaurants. Health Effects on Others People who use tobacco products are not the only ones at risk for negative health outcomes. Smoking and vaping both release substances into the air other people breathe. Secondhand smoke refers to the tobacco smoke released into the environment by people who smoke. People who regularly inhale secondhand smoke because they live or socialize with people who smoke have a greater risk of developing lung cancer or heart disease. Secondhand smoke is especially dangerous for children, as it can cause ear infections, asthma attacks, bronchitis, and pneumonia. Vaping devices release aerosol that others nearby can inhale. Aerosol inhaled involuntarily by others is called secondhand aerosol. Secondhand aerosol from vaping can contain harmful chemicals, such as diacetyl and heavy metals. If you socialize with a person who vapes, you are exposing yourself to similar health risks as if you were vaping. Thirdhand smoke and aerosol also affect people who are around others who use tobacco products. Thirdhand smoke refers to the particles and gases left over after a cigarette is extinguished. Similarly, the particles and gases left over from a vaping device are called thirdhand aerosol. The particles in thirdhand smoke and aerosol land and remain on virtually any surface in the area where someone has smoked or vaped (Figure 9.10).
