Legacy E-Cigarette Fact Sheet
"E-cigarettes (a product category that includes disposable cigarette-like, e-hookah, vape pens, and refillable tank-like or personal vaporizers) are devices that heat a solution (nicotine and other additives) producing a vapor that is inhaled without combustion. E-cigarettes vary in quality, safety, size, and efficiency of nicotine delivery. Current scientific evidence indicates that e-cigarettes are likely less harmful to individual users than combustible cigarettes. Since they have been on the market for under 10 years, their long-term effects are unclear. The science regarding how these evolving products impact patterns of tobacco use and public health is still in the early stages, but growing. This fact sheet contains information about e-cigarettes as it is known as of the date at the bottom of the page, and will be updated regularly as the science base grows."
