    Smokers are at a higher risk of heart attacks than non-smokers. When one smokes for a long time, the arteries thin out and supply insufficient oxygen to the heart. The thin blood vessels also get blocked by tar and carbon monoxide. When insufficiently oxygenated blood reaches the heart, a heart attack is likely to occur.
