My work has brought me to the conclusion that few physicians seem able accurately to classify their own patients. Even the specialist in psychology, who should be able to weigh all the details of men's mental and moral as well as physical being, seems likely to go astray when he considers a psychology that has been affected either by drink or drugs. Many physicians seem to be imbued with the idea that after a patient has once been through the process of treatment for a drug or drink habit he will be entirely made over; but the fact is that the elimination of drugs or drink from a degenerate will not eliminate degeneracy. Nothing, in fact, will eliminate it except stopping the breeding of degenerates. In my work I have found it necessary sometimes to seek advice from as many as half a dozen physical and psychological specialists in connection with one case. While instances have been very numerous in which several specialists have been really required for the welfare of the patient, the need had been so thoroughly concealed by the patient's drug habit that it was not apparent until the effect of the drugs was thoroughly eliminated. NECESSITY FOR CAREFUL PSYCHOLOGICAL STUDY In most instances expert treatment for the mental condition after drug or drink elimination is as essential as expert attention from the doctor of medicine, and if success is to be achieved, must be regarded as an entirely separate task. Habitual users of drugs or drink are literally human derelicts. The symptoms of their true condition are submerged, and to clear them of their concealed weaknesses it is necessary to lift them like a barnacle-ridden hulk into the dry-dock for investigation and repair. I regard as a preferred risk among the victims of the drug habits those who have acquired it through the administration of a narcotic by physicians in time of pain or illness. Such a case, if treated before too great a deterioration has taken place, may be considered almost certain of relief, provided no other ailment discloses itself.
