Carbon monoxide & nicotine: A dangerous duo
Carbon monoxide is a harmful gas you inhale when you smoke. Once in your lungs, it’s transferred to your bloodstream. Carbon monoxide decreases the amount of oxygen that is carried in the red blood cells. It also increases the amount of cholesterol that is deposited into the inner lining of the arteries which, over time, can cause the arteries to harden. This leads to heart disease, artery disease and possibly heart attack.
Nicotine is a dangerous and highly addictive chemical. It can cause an increase in blood pressure, heart rate, flow of blood to the heart and a narrowing of the arteries (vessels that carry blood). Nicotine may also contribute to the hardening of the arterial walls, which in turn, may lead to a heart attack. This chemical can stay in your body for six to eight hours depending on how often you smoke. Also, as with most addictive substances, there are some side effects of withdrawal.
Smokers aren’t the only ones affected by tobacco smoke. Secondhand smoke is a serious health hazard for nonsmokers, especially children. Cigarette smoke contains more than Nonsmokers who have high blood pressure or high blood cholesterol have an even greater risk of developing heart diseases when they’re exposed to secondhand smoke.
Environmental tobacco smoke causes about 46,000 heart disease deaths and 3,400 lung cancer deaths. Studies show that the risk of developing heart disease is about 25-30 percent higher among people exposed to environmental tobacco smoke at home or work. Secondhand smoke promotes illness, too. Children of smokers have many more respiratory infections than do children of nonsmokers. Nonsmoking women exposed to tobacco smoke are also more likely to have low-birthweight babies.
