280 Physiology. 



that those accustomed to such irritating smoke do not 

 show these symptoms is merely another proof of what 

 the system can learn to endure when it is compelled to 

 bear what is at first repulsive to nearly every human 

 being. 



Cigarette Smoking. Bad as other forms of smoking 

 are, this is still worse. Many cigarette smokers actually 

 inhale the smoke into the lungs. Here is not only the 

 irritation on the delicate mucous membrane, but the close 

 relation of the air and blood gives opportunity for absorp- 

 tion of the poisonous vapors into the blood. Again, since 

 the cigarette is small, many of them are used, the smoker 

 using one after another. The system is saturated with 

 nicotine, and the effect is usually much worse than from 

 any other form of smoking. 



Just as beer, with its smaller amount of alcohol, often 

 has a more injurious effect than some of the other alcoholic 

 drinks containing much more alcohol, so cigarettes, though 

 small, are much more injurious t than cigars. Perhaps this 

 is because, being so small, many of them are used, and so 

 the total amount of tobacco used is greater. But whatever 

 the cause, there are many observers who testify to the 

 fearful effects of the cigarette. 



Effects of Cigarettes. One of the instructors in the 

 naval academy at Annapolis said he could pick out the 

 boys who used tobacco because they were not able to draw 

 a clean, straight line. 



" After making a study of several hundred boys, running 

 through a period of ten years, I found accompanied with 

 the use of the narcotic were certain disordered physical 

 functions, such as nervous affections and diseases of the 

 heart." H. H. Seerly, Prin. Iowa State Normal School.
