student with an ambition to succeed in life can afford to 

 handicap himself by such a dead weight as the tobacco- 

 habit. Tobacco, like all other narcotics, gets a strong hold 

 on the system that habitually uses it, and we have but to 

 ask any habitual tobacco-user, to find how almost impossi- 

 ble it is to give up the habit after it is once formed. 



Effect of Tobacco on the Nerves. Tobacco affects the 

 nerves which have control of the muscles, so the use of 

 tobacco often causes loss of muscular power, not unfre- 

 quently resulting in paralysis. Even if no unsteadiness is 

 noticeable, there is less strength than before, and the young 

 man who uses tobacco unfits himself for going on any 

 athletic contest. Trainers are almost unanimous in for- 

 bidding the use of tobacco in their crews and teams. 



Effect of Tobacco on the Senses. It is stated on good 

 authority that there is no poison that has a greater destroy- 

 ing power upon the sensory nerves than nicotine. 



Effect of Tobacco on Sight JMicotine causes the pupils 

 to dilate ; this often causes obscurity of vision. In many 

 cases where the eyesight was affected, there has been 

 restoration on quitting the use of tobacco. 



Effect of Tobacco on Growth. The bad effects of tobacco 

 on the body are most plain in the young. It retards growth 

 and development. The law recognizes this in forbidding 

 the sale of tobacco to the young. The use of tobacco is 

 forbidden in our military and naval academies. 



" Tobacco retards both physical and mental development 

 of boys and youth. This effect is so fully proved that all 

 intelligent writers agree in prohibiting the use of narcotics 

 until maturity of growth has been attained." N. S. Davis,
