- Irrespective of the relationship between smoking and COVID-19, quitting smoking at any age is beneficial to health. There is no safe level of tobacco consumption.
- There is currently no direct evidence available examining the impacts of e-cigarette use on COVID-19 disease susceptibility and/or progression. However, there is increasing evidence that e-cigarette use poses a range of harms to the heart and lungs.
- Clinicians should use the opportunity to intervene with patients who are smokers or users of e-cigarettes and discuss options for quitting.
- Tobacco use was estimated to kill almost 21,000 Australians in 2015 and remains the leading cause of preventable death and disability in Australia.
- All Australian Governments are committed to reducing the prevalence of smoking and its associated health, social and economic costs, and the inequalities it causes.
- Up to two‑thirds of deaths in tobacco smokers can be attributed to smoking, and long term smokers die an average of 10 years earlier than non‑smokers.
