Not only was lung damage and the close relationship to cancer appearing, smoking also ranks among the villains when it comes to cardiovascular health. Cigarettes are one of the biggest aggressors to the endothelium, that wall of cells that covers the blood vessels. This action interferes with the production of a protective substance known as nitric oxide and makes the arteries more vulnerable to fat accumulation. There is also an interference with the contraction and relaxation mechanism, which results in greater difficulty for the blood to circulate. For this reason, we can say that smoking cigarettes increases the chances of heart disease.
