Switch from smoking to vaping cuts health risks substantially, report finds

Review of 400 published studies stresses 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.
