How do e-cigarettes affect the body?
E-cigarettes, which heat a liquid to create an aerosol that is inhaled, have negative effects on the respiratory and cardiovascular systems. The aerosol can contain harmful chemicals, worsen asthma symptoms, and increase the risk of respiratory infections. Nicotine in e-cigarettes can cause high blood pressure, heart disease, and stroke, as well as interfere with brain development in adolescents.
