NARCOTIC users are not confined to any one class of society. Physicians and nurses, because the drugs are so readily available to them, find the road to addiction particularly accessible. As a result, members of these two professions not infrequently yield to one rationalization or another and develop the narcotic habit. These professions, too, because of the very nature of their work, are responsible to some extent for the cultivation of addiction outside of their own ranks by the indiscriminate administration of drugs. The usual results of morphine addiction are a gradual disintegration of personality and character, with certain physical symptoms. The methods of treating drug addiction are (1) gradual withdrawal; (2) rapid withdrawl; and (3) complete withdrawal. Whatever the method the patient voluntarily submits to, it indicates that he still has considerable courage to even make an attempt to. give up such a crutch. The manifestations of abstinence are unbearable, and are well known by most addicts. Morphine addicts usually enter a hospital fortified with a huge dose of drug. Withdrawal symptoms generally appear in from twenty-four to forty-eight hours after the last dose. They consist -of pains in any or all parts of the body, especially abdominal pains, trembling, yawning, perspiring, nausea, vomiting, diarrhea, and often a weak irregular pulse. There is also a feeling of unrest and apprehensiveness. The patient is unable to sleep or take nourishment. The suffering is intense. In considering the general treatment, it is almost imperative that (1) the patient should be institutionalized; (2) all precautions are taken to make certain that the patient does not bring drugs into the hospital with him, -remembering that most drug addicts are confirmed liars; (3) nothing should be furnished to the patient except that which comes from within the hospital; (4) visitors should be excluded because sympathetic friends are often persuaded to bring in the drug; (5) a satisfactory elimination r6gime should be planned; (6) sedative tub baths should be used to allay discomfort and help to produce sleep; (7) specific treatment should be instituted for withdrawal manifestations. The insulin treatment has been used for withdrawal manifestations in morphine addiction in the Cincinnati General Hospital for three years. The rationale of the insulin treatment of the symptoms of morphine withdrawal is still conjectural for the most part. Manfred Sakel, the originator of this method of withdrawal, states that in morphinism there occurs a disarrangement of endocrine (especially adrenal) function which is ameliorated by insulin. Others feel that carbohydrate metabolism is directly altered in morphine addicts, that the habitual users of the drug become physiologically adjusted to this alteration, that the withdrawal of morphine disturbs the artificial metabolic equilibrium that has been attained by addicts, and that insulin somehow aids in a return to normal function. At best, these notions are
