Now medical researchers are discovering a truism: "alcohol and tobacco do not mix." These two substances, both dangerous to health, act synergistically, each making the other more powerful and thereby causing worse damage than either would do alone.
Because of this interaction, the person who both smokes and drinks heavily may be at a greater risk of becoming ill than one who drinks like a fish, but never smokes or who smokes like a chimney, but never drinks. To get an idea of how this synergism may work, consider what happens when a smoker lights up a cigarette. With each puff he inhales at least 4,000 different chemicals. These include toxic hydrogen-cyanide, carbon monoxide and nitrogen-dioxide gases, and four dozen compounds such as benzo pyrene and radioactive polonium 210. All are known as carcinogens. Most chemical vapors in tobacco smoke get deposited in the mouth, nose, throat and lungs
A. mixing effect
B. mixed function
C. combined result
D. cooperated effect
