The habitual use of cocaine for example, may be regarded as an indulgence of appetite and the obtaining of sensation and artificial stimulation and not as based upon the demands of a specific physical addiction-disease mechanism. The therapeutics of its discontinuance are entirely different. Habitual indulgence in cocaine tends to result in mental and moral deterioration. In the addict of the so-called “underworld” it is the coincident use of cocaine with its manifestations of mental, moral and physical deterioration that has led to the wide and erroneous attributing of characteristics of this class of cocaine habituates to the average opiate addict. The habitual use of cocaine is an entirely different matter from the continued administration of opiate in the case of an opiate addict, and its manifestations should be completely dissociated from the clinical picture and problem of opiate addiction-disease. Some writers, especially those associated with municipal or state institutions of penology and correction, lay emphasis upon the case of the so-called “mixed addict.” The crimes of violence with which addiction has become associated in the popular mind are practically never connected with the action of opiate drug. They are, however, characteristic of the cocaine crazed individual. When they are performed by a so-called “mixed addict” they are the result of cocaine habituation rather than of opiate addiction. Such crimes of violence as are committed by the opium or morphine addict are well explained in the Report of the Treasury Investigation Committee in the following words, “There are many instances of cases where victims of this disease were among people of the highest qualities morally and intellectually, and of the greatest value to their communities, who, when driven by sudden deprivation of their drug, have been led to commit felony or violence to relieve their misery.” This erroneous grouping of so-called “habit forming drugs” is to some extent responsible for a misconception of opiates and of opiate use and opiate result to such an extent that, there is unfortunately manifested at times a lack of appreciation of the very important legitimate uses of these drugs. The paramount issue of legitimate narcotic medication is that of the opiates. Opiates form and must continue to form the most indispensable medication, emergency and otherwise, for shock, wounds and allied conditions. It may be safely stated that of all emergency medication, the opiates would be the last to be surrendered by the intelligent physician or surgeon. This is true of every day civil practice and its importance is increased tremendously under conditions of active warfare.
