why is indoor smoking harmful and why is it banned in some of the countries
Indoor smoking is harmful because it leads to increase in passive smoking or second hand smoking. The tobacco smoke is heavier than air and instead of dispersing it forms a low lying smoke-cloud which is exposed to people who are present in the same environment as the smoker for inhalation.
That leads to many harmful effects and diseases, most of which are similar to the ones found with smokers such as lung cancer, asthma, bronchitis, stillbirths, infections, skin disorders, heart diseases, etc and hence it is banned in some of the countries.
