Vape juice or e-liquid is the liquid that is vaporized into an aerosol cloud. Vape juice most commonly contains three ingredients: propylene glycol and/or glycerin, chemicals for flavoring and nicotine.
99 percent of vape products sold in U.S. convenience stores contain nicotine, including popular products with teens. The amount of nicotine in brands like Juul, Puff Bar and Mojo can be equal to one whole pack of cigarettes.1 Some vape pods can also contain THC, the chemical in marijuana that makes the user feel “high.” Complicating the issue, vaping doesn’t give off the telltale smell of smoking marijuana or cigarettes.
