Tobacco accounts for more than 8 million deaths on a global level each year. Out of this figure, 7 million deaths are caused by direct use of tobacco and around 1.2 million deaths are the non smokers who are exposed to second hand smoke. The use of tobacco is a high risk factor for respiratory diseases.
A review of studies by public health experts convened by WHO in April 2020, found that smokers were more likely to get affected by Covid 19 rather than non smokers as it basically attacks the lungs and smokers find it difficult to fight against the virus. WHO is evaluating new research that examines the link between the use of tobacco, nicotine and Covid 19. It recommends that smokers take immediate steps to quit smoking.
