In the last year 3 acquaintances of mine had heart attack of some sort. The doctor said that smoke was the main reason for all 3 of them.
I read most chainsmokers die of heart attack instead of lung cancer but i don’t understand why.

Nicotine causes your blood vessels to constrict which limits the amount of blood to your organs. The constant constriction causes blood vessels to stiffen and are less likely to return to normal size. This causes prolonged damage to organs, especially the heart and brain.
