It must also be remembered that, like the doctor, the nurse is human, and neither iron-nerved nor iron-muscled. She is frequently under terrific strain, which makes her tend toward the use of stimulants of any kind. That which she can administer to herself by means of the hypodermic is closest to her hand, is easiest to take, and is least likely to be discovered. Again, too, it must be remembered that the nurse is as susceptible to pain as are the rest of us. Suffering, with the means of alleviation at her hand, and, like the doctor, ignorant of its true peril, what is more natural than that she herself should use the hypodermic for her own relief? Thus it comes about that probably a larger proportion of trained nurses than of doctors are habitual drug-users. This is not a statement which is critical of the profession, for if all mankind knew of drugs, had hypodermics, and knew how to use them, a very large proportion of the human race would resort to this quick and effective, if inevitably perilous, means of finding comfort when agony assailed them. The world does not, the world cannot, understand that while to the normal human being the worst that can come is pain, the worst pain is vastly less terrible than the horrors which at intervals inevitably afflict the habitual drug-user. Not one human being who has become a victim of a drug habit through its use for the alleviation of pain but will voluntarily cry after he has come to realization of the new affliction which possesses him, "save me from this drug habit, and I will cheerfully endure the pain which will ensue." The horror of pain is not so great as the horror of the drug habit. Another very serious reason for extreme caution on the part of the medical profession in regard to the use of habit-forming drugs is that the effect of such drugs upon a patient must almost certainly make accurate diagnosis of his case difficult or even impossible. A patient whose consciousness of pain is dulled or eliminated by the use of drugs cannot accurately describe to a physician the most important symptoms of his ailment. Without the assistance of such a description the physician is so handicapped that all the skill which he has acquired in practice and all the knowledge he has gained from study are apt to be of no avail. Indeed, in the case of habitual drug-users accurate diagnosis of any physical ailment is impossible until the effect of the drug has been so completely eliminated that not one vestige of it remains. CHAPTER V ALCOHOLICS I am not specially familiar with the statistics of insanity, but I am inclined to believe that an appreciable contribution to the total--indeed, one of its largest parts--has arisen from the improper diagnosis of drug and alcoholic cases, followed naturally by improper medical treatment. Lack of definite medical help in cases of chronic alcoholism is likely to bring about brain lesions, which eventually mean hopeless insanity.
