"Poison" is commonly defined as "any substance that when taken
into the system acts in an injurious manner, tending to cause death
or serious detriment to health." And different poisons are defined
as those which act differently upon the human organism. For example,
one class, such as nicotine in tobacco, is defined as that which acts as
a stimulant or an irritant; while another class, such as opium, acts with
a quieting, soothing influence. But the fact is that poison does not act
at all upon the human system, but the human system acts upon the
poison. In one class of poisons, such as opium, the reason why the
system does not arouse itself and try to cast off the poison, is that the
nerves become paralyzed so that it can not. And in the case of nicotine
in tobacco the nerves are not thus paralyzed, so that they try in every
way to cast off the poison. Let the human body represent the house,
and the sensitive nerves and the delicate blood vessels the sleeping
inmates of that house. Let the Foe Opium come to invade that house
and to destroy the inmates, for every poison is a deadly Foe. At the
first appearance of this subtle Foe terror is struck into the heart of the
inmates, so that they fall back helpless, paralyzed with fear. When
the Intruder Tobacco comes, he comes boisterously, rattling the
windows and jostling the furniture, so that the inmates of the house
set up a life-and-death conflict against him.

This is just what happens when tobacco is taken into the human system.
Every nerve cries out against it, and every effort is made to resist it.
You ask, Will one's body be healthier and live longer without tobacco
than with it? We answer, by asking, Will one's home be happier and
more prosperous without some deadly Foe continually invading it, or
with such a Foe? When the membranes and tissues of the body, with
their host of nerves and blood vessels, have to be fighting against some
