According to Cancer Research UK: “There is no good evidence that vaping causes cancer.
“Some potentially dangerous chemicals have been found in e-cigarettes but levels are usually low and generally far lower than in tobacco cigarettes. Exposure may be the same as people who use nicotine replacement therapy (NRT) such as patches or gum.”
The Office for Health Improvements and Disparities (formerly Public Health England) says vaping is ‘at least 95% less harmful than smoking’.
