Review of 400 published studies also says vaping is not risk-free and urges action to reduce teenage use
Vaping is substantially less harmful than smoking, according to a major review of nicotine products, but action is needed to tackle the sharp rise in e-cigarette use among children.
Researchers at King’s College London said smokers who switched to vaping would experience a “substantial reduction” in their exposure to toxic substances that cause cancer, lung and cardiovascular disease, but they strongly urged non-smokers not to take up either habit.
