The reason why is they have specific immunoglobulin to covid-19 since in their past having contracted common colds due to many strains of coronaviruses, they have crossreactivity so they become also immune to the covid-19.

SMOKERS CONTRACT COVID-19 SIGNIFICANTLY LESS AND MILDER!

MY HYPOTHESIS:
WHY SMOKERS CONTRACT COVID-19 SIGNIFICANTLY LESS AND MILDER?
Most probably, since smoking is chronic inflammatory process in nasal mucosa and also smokers most often smoke outside or by an open window they contract much more easily common cold and often their mucosa. Due to these multiple contractions of common colds, they have antibodies to both coronaviruses and rhinovirures which are the most etiologic viruses in common cold (coryza) cases. Due to cross reactivity of coronaviruses antibodies they are considerably immune or resistant to covid-19. These coronaviruses antibodies cause significant loss of smelling also. More common colds and less smoking simply means more immunity to covid-19.
Smokers at increased risk of COVID-19 infection, severe disease, and death.
It is well certain people may get a milder COVID-19, due to their robust immune system. However, you are misinformed that smokers get a milder COVID-19. In fact it is the opposite.
Smokers are at a higher risk to get COVID-19 and have a severe disease with increased mortality. Smokers are also more likely to spread the SARS-CoV-19 if they are infected.

Dear Sinan Ibaguner,
Is it proven fact that smokers are more affected by COVID-19 than non-smokers ?
I don't think so, though I don't have any data .
Thanks

The infection depends on the person’s immunity, as some have strong immunity and others have an imbalance in the immune system.
Will you please read also my discussion part down the the main questions and investigate one by one the 10 related websites I listed there before you reply. Thank you for your comments.
1. Many factors; pre-existing cross reactive antibodies, exposure to a smaller virus load, a more robust immune system (age, genetics, etc.)
2. Smokers do not have normal lungs and this virus can compromise lung function even further. In addition, and although controversial, smoking suppresses certain parts of the immune system.
It is a myth that smokers are protected against COVID-19.
