Health organisations call for stronger tobacco control as new study links smoking to higher risk of dying from COVID-19

Health organisations call for stronger tobacco control as new study links smoking to higher risk of dying from COVID-19

Dr Sharon Nyatsanza of the National Council Against Smoking (NCAS) says a respiratory pandemic is an opportune time for an increased focus on tobacco control, especially as new evidence shows a strong link between smoking and increased risks of severe COVID-19. According to UK Biobank research published in a leading respiratory journal, Thoraxsmoking increases the chances of developing severe COVID-19 symptoms by 80% and increases the risk of death by 511%, for smokers who smoke 20 or more cigarettes a day. 

The new study found that compared with those who had never smoked, current smokers were 80% more likely to be admitted to hospital. It found that heavy smoking significantly increased chances of dying from COVID-19 complications, by up to 511% for those who smoked 20 or more cigarettes a day – compared to non-smokers. The UK study drew on primary care records, COVID-19 test results, hospital admissions data and death certificates to look for associations between smoking and COVID-19 infection severity from January to August 2020 in over 400 000 participants of the UK Biobank. 

“This study strengthens the evidence base and establishes a causal link between smoking and serious COVID-19 complications,” says Dr Sharon Nyatsanza, Deputy Director of the National Council Against Smoking. “It also supports the Cooperative Governance and Traditional Affairs (Cogta) Minister’s case, who has since been granted leave to appeal the Western Cape Judgement over the temporary ban on tobacco sales. A key justification raised by government, was that tobacco use was linked to worse Covid-19 outcomes and that the ban was important in easing the burden on the health system.”

Nyatsanza highlights the importance of passing South Africa’s new Control of Tobacco Products and Electronic Delivery Systems Bill as soon as possible, particularly with reports from the South African Medical Research Council (SAMRC) indicating that the death toll from Covid-19 is up to three times more than reported, making South Africa one of the worst affected countries in the world.  “We need urgent action to pass this updated and comprehensive set of measures to better protect our nation’s health and reduce the burden of tobacco-related disease on our health system, now and beyond the pandemic.”

Nyatsanza says that encouraging people to quit smoking and reducing smoking prevalence should be high on the list of preventive steps, as it keeps people out of hospital.  “Smoking is related to the risk of getting severe Covid-19, as it is to a number of non-communicable diseases like cancers and cardiovascular disease. Now is the time to quit smoking.”
