The Office for Health Improvements and Disparities (formerly Public Health England) says smoking remains ‘the largest single risk factor and years of live lived in ill-health globally’ and is ‘a leading cause of health inequalities in England’.
Vaping, on the other hand, is 95% less harmful than smoking. The Centre for Economics and Business Research analysed data from 2019 and calculated that for that year alone the NHS saved £322m because of smokers switching to vaping.
