that the smoker is not content simply to absorb the nicotine through the mucous membrane of the mouth; he draws it into the lungs. The very mildness of the smoke leads to inhalation. Hence, as the surface of the lungs is a hundred times greater than the surface of the mouth, and its lining much thinner, cigarette smoking is far more injurious than cigar smoking.
The poison accumulates in the bowl of a pipe; hence an old pipe
is very injurious. The irritation of tobacco smoke often sets up a
chronic dry catarrh
of the air passages;
rarely it causes cancer
of lips or tongue. Sir
Henry Thompson
says: "The only persons
who enjoy smoking
and find it tranquillizing
at times are
those who smoke in
great moderation.
Men who are rarely
seen without a cigar
between the lips, have
long ceased to enjoy
smoking. They are
confirmed in a habit,
and are merely miserable
when the cigar is
absent." They do not
smoke for pleasure,
but to escape misery
which wiser men
escape by avoiding
tobacco altogether.
