"Every drug capable of producing an artificial exhilaration of spirits, a pleasure which is not the result of the natural play of the vital functions, is necessarily mischievous in its tendencies, and its use is intemperance, whether its name be alcohol, tobacco, opium, cocaine, coca, kola, hashish, Siberian mushroom, caffeine, betel-nuts, mate or any other of the score or more enslaving drugs known to pharmacology. As the result of the depression which follows the unnatural elevation of sensation resulting from the use of one of these drugs, the second application finds the subject on a little lower level than the first, so that an increased dose is necessary to produce the same intensity of pleasure or the same degree of artificial felicity as the first. The larger dose is followed by still greater depression which demands a still larger dose as its antidote, and thus there is started a series of ever-increasing doses, and ever-increasing baneful after-affects, which work the ultimate ruin of the drug victim. All drugs which enslave are alike in this regard, however much they may differ otherwise in their physiological effects. Alcohol is universally recognized as only one member of a large family of intoxicating drugs, each of which is capable of producing specific functional and organic mischief, besides the vital deterioration common to the use of so-called felicity-producing drugs. "Is it not evident, then, that in combating the use of alcohol we are attacking only one member of a numerous family of enemies to human life and happiness, every one of which must be exterminated before the evil of intemperance will be up-rooted?" Among the most popular drugs for self-prescription at the present time are the coal-tar products. Of these Dr. N. S. Davis has said:-- "Only a few years since, the profession were taught to regard the degree of pyrexia, or heat, as the chief element of danger in all the acute general diseases. Consequently, to control the pyrexia became the leading object of treatment; and whatever would do this promptly, and at the same time allay pain and promote rest, found favor at the bedside of the patient.
