What is commonly spoken of as the "American type," highly nervous, living under pressure, always going to the full limit, or beyond, is peculiarly liable to disorders that lead to the habitual use of drugs. We are all hypochondriacal by nature, prone to "take something" whenever we feel badly. Lack of opportunity alone, of knowledge of what to take and how to procure it, has saved many a person under severe physical or mental strain from recklessly resorting to drugs. Since the passage of the Pure Food and Drugs Act, which was intended to protect the public by requiring the express statement of any dangerous ingredients in a compound, the sale of preparations containing habit-forming drugs has preceptibly increased. It seems a just inference that the information given, instead of serving as a warning to the unwary, has been chiefly effective in pointing out a dangerous path to many who otherwise would not have known where to find it. Women, it should be said, though constitutionally more liable than men to feel the need of medicines, form the lesser portion of the drug-taking class. In the beginning their addiction is due almost exclusively to a physician's prescription, except in the under-world. The habitual users of drugs in the United States come from every grade of society. Professional men of the highest responsibility and repute, laborers wearying of the dullness in a mining-camp, literary men, clergymen, newspaper men, wire-tappers, shoplifters, vagrants, and outcasts--all are among the number. Strangely assorted as they are, they become yet more strangely alike under the influence of the common habit. Shoplifting is not confined to the professional thief; it is noticeable in many a drug-user who has had every moral and worldly advantage. The major part of the habit-forming drugs used in the United States is consumed by the under-world. It would be impossible to calculate the extent of their influence. Many a record of heinous crime tells of the stimulus of a drug. But when the school-children in some of our larger cities are found to be using cocaine, and able to buy it at will, the limit of tolerance has surely been reached.
