This increases the risk of having blood clots which will block the blood flow to your heart, brain, or even legs. Smoking can lead to heart disease or a stroke and also can lead to atherosclerosis
If you ask what atherosclerosis is, these are built-up fats, cholesterol, or any other substances in and on the artery walls which can build up plaque. When plaque is made this can cause arteries to narrow or blocking blood flow. The plaque can also burst and lead to a blood clot.
