This document discusses the safety of e-cigarettes and vaping. It outlines that while e-cigarettes were initially promoted as a safer alternative to smoking and a way to quit smoking by gradually decreasing nicotine levels, health organizations now caution against claiming they are safe. Some studies have found e-cigarette vapor contains dangerous substances like formaldehyde at higher levels than regular cigarettes. Concerns also exist around the chemicals in e-liquid flavorings, as researchers have found certain flavorings to contain chemicals above safe levels for inhalation. In the end, the document concludes that both e-cigarettes and regular cigarettes contain toxic elements, so there is no need to debate which is worse.
