Q.—How does tobacco injure digestion? A.—The saliva which is needed to soften the food is either spit out or poisoned with tobacco, and this weakens the action of the stomach. Q.—What other effect has tobacco upon the stomach? A.—It relaxes the lining of the stomach and bowels, often causing hemorrhage and other stomach and bowel affections. Q.—Does tobacco poison the blood? A.—Yes; and every other portion of the system. Q.—How do we know it poisons the blood? A.—Because when leeches are used to suck out an inveterate smoker's blood, they are instantly killed by it. Q.—What part of the body does tobacco effect the most? A.—The heart. It weakens its action and makes it irregular, so that it does not send a full supply of blood through the body, and the muscles become weak and flabby. Q.—Does tobacco cause heart disease? A.—Medical statistics show that about one out of every four tobacco users has palpitation or some trouble of the heart. Q.—What effect does it have on the nerves? A.—Those who use tobacco are more or less afflicted with sleeplessness, irritability of temper, and trembling of hands. Q.—What effect does tobacco have on the mind?
