Nicotine Without Smoke: Tobacco Harm Reduction

Resource Type: | Focus: , , | Tone: ,

Resource Notes:

This report is the most common source for claims from vaping advocates that vaping is “95% safer” or “95% Less Harmful” than smoking. The proper quote, which can be found on page 87 at the end of the chapter 5 summary: “Although it is not possible to precisely quantify the long-term health risks associated with e-cigarettes, the available data suggest that they are unlikely to exceed 5% of those associated with smoked tobacco products, and may well be substantially lower than this figure”.


The published statement as mentioned in the Notes column has received criticism from multiple sources since publication. However, to date it remains the only stated numerical representation of the comparative relative risk between vaping technology and combustion based delivery systems and has been restated, without correction or adjustment, by the RCP in publications every year since the release of this report.
