Smoking the Number 1 Cause of Preventable Heart Disease and Death. Roughly 1 out of 5 Death from heart disease is directly due to smoking.

How smoking causes deposition fatty layers

The main mechanism remains that Smoking cause deposition fatty plaques in the interior of blood vessel a process called as atherosclerosis, though this is age related however is accelerated in smokers leading to early development of blockages that impede blood supply to the heart resulting in Angina or chest pain at the time of effort and the spectrum goes on to include Minor and Major/Fatal Heart Attacks or Myocardial Infarction

Increased risk of heart attacks and cigarettes smoked per day

Studies have shown that increased risk of heart attacks is also for people who smoke less than 5 cigarettes a day hence making any level of smoking unsafe.

Hence there is no safe level for smoking and cardiovascular disease.

What makes smoking so dangerous?

What makes smoking even more dangerous is that cigarettes are easily available, can be smoked anytime, anywhere, and are cheap. They have only a psychological dependence, smokers usually smoke when they are happy or sad or have nothing to do or something major to do which is purely a psychological dependence.

But when you think that even if you stop smoking today your risk of having a heart attack will be reduced only after 3 years and the risk of having lung cancer will be comparable to a non-smoker only after 10 years maybe you will feel more motivated.

Cigarette smoking is not just hazardous it can be fatal and there is no safe level to it so quit it as reducing numbers will not help!!
