Unfortunately for the race, we have accustomed ourselves to partake of
beverages containing injurious, poisonous substances. Inasmuch as this
is the place to discuss the drugs contained in coffee and tea, I shall
take the liberty of dwelling upon other habit-forming substances in the
same chapter. They are all a part of the drug addictions of the race.
For scientific discussion of these various substances I refer you to
technical works. In this chapter will be found only a discussion of
their relation to people”s welfare, that is, to health and efficiency.
