Are e-cigarettes safe to use?
- E-cigarette aerosol is not harmless water vapor. In addition to nicotine, e-cigarette aerosol can contain heavy metals, ultrafine particulates that can be inhaled deep into the lungs, and cancer causing agents like acrolein.
- E-cigarette aerosols also contain propylene glycol or glycerin and flavorings. Some e-cigarette manufacturers claim that the use of these ingredients is safe because they meet the FDA definition of “generally recognized as safe” (GRAS). However, GRAS status applies to ingestion of these ingredients (i.e., in food), not inhalation. The health effects of inhaling these substances, including from an e-cigarette, are unknown.
- Inhaling e-cigarette aerosol directly from the device or from secondhand aerosol that is exhaled by users is potentially harmful to health. Therefore, adult nontobacco users should not use e-cigarettes or be exposed to secondhand aerosol from these products.
- E-cigarettes are not an FDA-approved smoking cessation aid. The US Preventive Services Task Force, a group of health experts that makes recommendations about preventive health care, has concluded that evidence is insufficient to recommend e-cigarettes for smoking cessation in adults, including pregnant women.
- E-cigarettes increase risk of nicotine poisoning through intentional or accidental ingestion of e-cigarette liquid, absorption of e-cigarette liquid through the skin, or inhalation of e-cigarette aerosol.
