If you already have a health condition, stopping smoking still matters.

Smoking can make existing health problems worse and raise the risk of further illness. These pages focus on the connection between smoking and specific conditions, and where to find trusted help.

The current Wales burden: Public Health Wales estimates an average 3,845 smoking-attributable deaths and 17,195 smoking-attributable hospital admissions a year among adults aged 35+ in 2020–22. An estimated 10.7% of deaths in this age group were attributable to smoking. These are modelled attributable-burden estimates, not a cause recorded on every individual death certificate or hospital admission. Public Health Wales source ↗
