• E-cigarettes, also known as electronic nicotine delivery systems (ENDS), are devices that emit an aerosol containing nicotine and/or other chemicals that is inhaled by users.  They include e‑cigarettes, e‑cigars, e-pipes, e-hookahs, and vape pens.
• E-cigarettes typically use a battery to heat a liquid solution called an e-liquid, while some e-cigarettes heat solid substances such as nicotine salts.  This produces an aerosol that can be inhaled without burning tobacco.

• E-liquids typically contain nicotine, which is on the Proposition 65 list.
• When some e-cigarettes are used, they can release other chemicals that are on the Proposition 65 list, such as cadmium and lead.

• During pregnancy, nicotine and other chemicals from e-cigarettes can pass from mother to baby.
