Heart
Heart disease is not uncommon in smokers. Toxic substances in tobacco products can cause permanent damages to blood cells, blood vessels, as well as the heart. Over the long run, this can be a major risk factor for many health problems, including cerebrovascular disease, peripheral vascular disease, stroke, heart attack, or coronary heart disease. Both nicotine and carbon monoxide from smoke would put more pressure on your heart and force it to beat faster, which might cause blood blots. Many other components can build up gradually along the walls of blood vessels and affect blood flow to other body parts. [3]
