    The risk is higher depending on how heavily one smokes. Passive smokers are no exception, but less likely to experience heart attack via tobacco. Smoking causes arteries/veins to constrict (tighten). If the person has too much cholesterol in his or her system, then the constriction caused by the nicotine can cause the blood vessels to stick together—inducing a heart attack. Also, the ingredients in nicotine are considered "uppers." They cause the heart to beat faster and work harder than necessary. Finally, the contamination smoking causes to the lungs makes the heart work more than it normally needs to. The smoke kills the oxygen capacity of RBC's (red blood cells). All of this undue stress can cause a heart attack over time.
