Thanks for your question on Health Care Magic.
I can understand your situation and problem.
Smoking in any form is harmful for the body.
Especially tobacco smoke is most dangerous.
It damages lung the most.
It causes constant irritation and inflammation in the lungs. It weakens lung defense and make it prone for infection.
So better to first quit smoking as soon as possible, it is not good habit.
Consult pulmonologist and get done
1. Clinical examination of respiratory system
2. Chest x ray
3. PFT (Pulmonary Function Test).
Chest x ray is needed to rule out
lung infection and
lung cancer.
PFT is needed to rule out
bronchitis.
So quit smoking, first diagnose yourself and then start appropriate treatment.
Hope I have solved your query.
Wish you good health. Thanks.
