Although we think of lung cancer as the disease of tobacco, the weed is associated with other cancers, with respiratory disease (such as emphysema), and with heart and circulation conditions (cardiovascular disease). Not only do the chemicals in tobacco smoke trigger mutations within cells that lead to cancer, and damage the lungs, but they also stiffen the walls of the blood vessels. That requires the heart to work harder, so smokers are more prone to coronary heart disease (CHD) and stroke. Stopping smoking is the best way of preventing heart disease.
