to
become less sensitive to the rights of others, this being evidenced by
smokers who do not hesitate to make rooms and public halls almost
unbearable to those unaccustomed to tobacco.

*Counts against Nicotine.*--The physiological objections to the use of
tobacco, as already stated (pages 56, 92, 326, 333, 336), are the
following:--

1. The use of tobacco before one reaches maturity stunts the growth. The
boy who uses it cannot develop into so strong and capable a man as he
would by leaving it alone.

2. Tobacco injures the heart.

3. Tobacco injures the air passages, especially when inhalation is
practiced.

4. Tobacco injures the nervous system and by this means interferes in a
general way with the bodily processes. For the same reason it interferes
with mental and moral development, the cigarette being a chief cause of
criminal tendencies in boys.

5. In some cases tobacco injures the vision.

6. The tobacco habit is expensive and is productive of no good results.

*Tobacco and the Rising Generation.*--The problem of limiting the use of
tobacco to the point where it would do slight harm, in comparison to what
it now does, would be solved if those under twenty years of age could be
kept from using it. But few would then acquire the habit, and those who
did would not be so seriously injured. In our own country it lies within
the province of the home and the school to bring about this result. The
fact that parents use tobacco is no reason why the boys should also
indulge. The decided difference in effects upon the young and upon the
mature makes this point very clear. Laws protecting boys from the evil
effects of tobacco, not only cigarettes, but other forms as well, are both
just and necessary.

*Social Custom and the Caffeine Habit.*--By suitable processes a white,
crystalline solid, easily soluble in water, can be separated from the
leaves of tea, and from the berry of the coffee plant. This is the drug
caffeine, the substance which gives to tea and coffee their stimulating
properties, but not their agreeable flavors. Less injurious, on the whole,
than either alcohol or tobacco, caffeine has come into general use in much
the same way as these substances. In a sense, however, caffeine is more
deceptive than either alcohol or nicotine, because the usual mode of
preparing tea and coffee gives them the appearance of real foods. The
housewife who would feel condemned in purchasing caffeine put up as a drug
