electronic nicotine delivery systems go by many names. The most common name is “e-cigarettes,” but others such as e-cigs, vapes, vape pens, mods and tanks are also common terms. Most recently, new products, such as JUUL, voopoo vape have created brand-centric terms for product use (“JUULing”). For this resource, the entire category will be referred to as “e-cigarettes.”
E-cigarettes are devices that operate by heating a liquid solution to a high enough temperature so that it produces an aerosol that is inhaled.
Solutions, sometimes called e-liquids, typically include nicotine, flavoring and a humectant, such as propylene glycol, to retain moisture and create an aerosol when heated.
Many of the flavorings and humectants used in e-liquids have been approved by the Food and Drug Administration for oral consumption, but not for inhalation, due to the lack of research regarding the safety of these compounds when inhaled.vaporesso vape
Some newer e-cigarettes on the market have nicotine salts in e-liquids — prompting questions about the use, purpose and safety of this novel form of nicotine. The makers of JUUL claim that their nicotine salt formulation increases the rate and amount of nicotine delivered into the blood, compared with other formulations.
While using an e-cigarette is often called “vaping,” the devices produce an aerosol, not a vapor. Unlike vapor, which is simply a substance in gas form, the aerosol from an e-cigarette can contain tiny chemical particles from both the liquid solution and the device (e.g., metals from the heating coil).u2022eney7485yyWEEEEDD
