being decomposed. All writers have agreed that 
chewing is the worst way that tobacco can be 
used. Dr. R. V. Dolbey says: (Northwest 
Medicine, 1909, V. 1 p. 99). 
“In chewing, quantities of watery extract of 
tobacco are swallowed and taken down with 
the food containing a large percentage of nico- 
tine and causing severe dyspepsia. While to- 
bacco juice solution in the laboratory kills in- 
testinal bacteria, excessive tobacco chewing 
does not have this effect on the human body 
owing to the fact that the gastric and pan- 
creatic juices act on it and alter it.” 
Dr. I. 8S. Gilfilian discusses the effects of to- 
bacco on the heart in the St. Paul Medical 
Journal, July, 1912, p. 838. He says that the 
important part whether organic changes in the 
cardio-vascular system may be produced by 
tobacco is still doubtful, and that it has never 
been shown that smokers suffer more from or- 
ganic heart disease than nonsmokers. 
General opinion is that smoking lessens the 
pulse rate and slightly increases the blood pres- 
sure, and that it is a cause of arterio-sclerosis. 
With regard to arterio-sclerosis, Dr. A. Lor- 
and of Carlsbad who is a world-wide authority 
on the effects of toxic substances on the blood, 
says in his book, Old Age Deferred (English 
translation, 1910, p. 367):
