The use of tobacco in the cigar or the pipe is less objectionable than in the cigarette for many reasons. It is the almost universal custom of those addicted to the cigarette to inhale the smoke, which is the exception with the pipe and cigar smoker. But nicotine is not the only poison generated in the cigarette even where tobacco is not combined with opium or other drugs used to contribute to its flavor and aroma; the combustion of tobacco with the rice paper in which it is rolled makes a compound which is neither tobacco smoke nor paper smoke, but an alkaloid known as acrolein, “the name of which is known to all scientists and the smell of which is known to everyone.” Another injurious product of cigarette combustion is carbonic oxide. These two products of the cigarette are far more virulent than tobacco smoke. They enter the blood through the mucous membranes of the mouth, throat, bronchial tubes, and lungs and act as powerful depressives on the heart. Cigarette poisoning manifests itself in lung and throat irritation, restlessness, nervousness, petulance, inability to concentrate thought, and depression of the nervous system. The effect is not only physical but moral. The keen sense of discrimination between right and wrong is blunted and the finer moral conceptions become obtused. The highest scholarship in our colleges and universities is attained by men who are non-smokers. The famous college athletes have a smaller proportion of smokers than those who have not achieved distinction in athletics. If these facts are true of college men approaching maturity, they will be still more apparent in younger boys. Unfortunately, there has been no scientific investigation along these lines among boys in our secondary schools. But the head of one of our leading preparatory schools is authority for the statement that tobacco is the bane of his school and that more boys break down in health and are sent home from its influence than from any other. A recognition of the evil results of cigarette smoking by minors is crystallized in the enactment of laws in more than a dozen states against selling cigarettes to minors, as well as making it an offense for adolescents under specified ages to smoke cigarettes on the streets. The records of juvenile and criminal courts disclose the fact that the cigarette fiends furnish 90 per cent. of their young criminals. Dr. George F. Butler of Chicago gives this testimony as to the moral weakening of the boy from the cigarette habit: “In my work some years ago at the Chicago police stations and later as county physician in the detention hospital I found that almost without exception the young criminal, dement or delinquent, was a cigarette fiend. I am forced to believe that this habit has largely to do with these mental and moral infirmities.”
