Smoking (these data are preliminary)
13 studies covering 5,960 hospitalized COVID-19 patients: 6.5% recorded as smokers (average)
Peer-reviewed study of 50 hospitalized COVID-19 patients: 6% recorded as current smokers
We are still in the early days of the COVID-19 pandemic, and many questions remain. What is the relationship between smoking and risk of infection, hospitalization, or severe complications? Do smokers who switch to vaping nicotine face similar risks? And, finally, is the media reporting on these issues accurately?
The only certain answer to the first two questions is that it’s too early to say. We need more data. Ideally, a careful nicotine use history would be recorded for all patients with COVID-19 admitted to hospitals. Where feasible, these patients would be tested for nicotine use and for the products of combustion from cigarettes and bidis to verify self-reported histories.
As scientists love to say, “More research is needed.” There are knowns, known unknowns, and probably a lot of unknown unknowns. Current evidence on the relationship between COVID-19, smoking and nicotine vaping ranges from strong to none.
Long-term smokers are more likely to suffer from colds, influenza, and pneumonia than non-smokers. They are also more likely to develop ‘comorbidities’ like chronic obstructive pulmonary disease (COPD). However, at least in the United States, ‘only’ 13–15% of current smokers suffer from COPD. These individuals are more likely to suffer severe COVID-19 complications.
Based on the above table, there is currently no evidence that smokers who are diagnosed with COVID-19 are more likely to be hospitalized than non-smokers. But disease severity may differ. For example, one study of 1,099 COVID-19 patients in China found that 21% of smokers, and only 14% of non-smokers, developed complications. Unfortunately, there is no evidence yet on any potential links between COVID-19 and vaping. There is, however, intriguing evidence that most smokers who switch to nicotine vaping have fewer respiratory tract infections (colds and flus), coughs, and phlegm.
So far, there is no credible evidence that smokers or nicotine vapers are more likely to be infected with coronavirus. Nor is there evidence linking vaping to COVID-19 hospitalization or complications. Logically, there are three possibilities for nicotine vapers — vaping may increase, decrease, or have no effect on COVID-19 risk. All three possibilities should be studied during this pandemic.
Is the media reporting this accurately?
Here is a small, representative snapshot of relevant global news between April 8 and April 13, 2020:
The relationship between smoking and COVID-19 is complex, possibly counterintuitive, and rarely reported accurately in the press. With or without COVID-19, we must never forget that there is overwhelming evidence linking smoking to 7 million deaths every year from cancer, heart, and lung disease. There is an urgent need to develop and ensure access to safer and more effective smoking-cessation products and services.
* Average smoking rates for adults (male and female) in each country. In France, Germany, and the United States, gender differences in adult smoking are modest. Note, however, that in China at least 44.8% of men smoke, but only 2% of women.

Dr. Kgosi Letlape discussed some of the many reasons that global efforts to end smoking have stalled on @eNCA. Dr. Kgosi is a member of the International Commission to Reignite the #FightAgainstSmoking. For more about the Commission Report, click here: https://fightagainstsmoking.org/

In #Pakistan, more than 160,000 people die annually from tobacco-related illness. Lack of cessation aids are intensifying the use of combustible cigarettes in the country. For more on the health & economic consequences of #tobacco in Pakistan click here:
It is simply unacceptable that global consumption of #cigarettes is the same today as it was 30 years ago. The International Commission was created to consider new solutions for preventing deaths from tobacco use. #FightAgainstSmoking https://www.fightagainstsmoking.org/
Pieter Vorster believes that the tobacco transformation index is a useful tool for investors and will become more important in the future. #GTNF2021
As @thegtnf comes to a close, a panel on investment will continue the dialogue on the impact investors have on #tobacco companies. For more on the path ahead, explore the Tobacco Transformation Index: https://tobaccotransformationindex.org/
