Drug addiction likewise decreases the industrial efficiency of its victims. Drug addicts among homeless men seldom are transient. Those who are transient are often cocaine users who are able to do without the drug for considerable periods of time. Not infrequently “coke heads” or “snow-birds” are found among the hobo workers. When on out-of-town jobs, they are prone to go to town occasionally to indulge in a cocaine spree much as a “booze-hoister” indulges in a liquor spree. When their money is gone they return to work and do not touch the “snow” for weeks or months. Users of heroin or morphine are not able to separate themselves from the source of supply for so long a time. Because of the secret nature of the practice, the extent of drug addiction among homeless men is unknown. Men who use drugs are loath to disclose the fact to anyone but drug users. The drug addict employs every scheme to keep his practice a secret whereas the drinking man strives to share his joy with others. The fear of being discovered drives many addicts from the circle of their family and friends and many of them drift into the homeless man areas where they enjoy the maximum seclusion. 17. The investigator was accosted by a beggar in the Loop. He was impressed by the fervor and the hurry with which the man begged him and was away. He followed the man for several blocks and watched him accost more than a hundred persons, all men. The only men from whom he failed to solicit were those accompanied by women. If two men were standing two or three yards apart he accosted each one individually. Only one or two men gave him anything. Most of them looked with suspicion at him, and not without reason, for although he was fairly well dressed he was very dirty and his clothes looked as if he had been sleeping out. He had a pallid, leaden complexion, and he had a ten days’ growth of beard. He had a wild, hunted expression and impressed the investigator as being a drug addict. He continued to follow the man and engaged him in conversation. He learned that he had just beat his way from Boston. He had ridden passenger trains all the way and had come in less than three days. His only difficulty was in Buffalo where he says that a policeman pulled him off the train and beat him. Why he left Boston he would not say. He denied being a “dope” then and it was not till three days later when he was seen in Grant Park that he admitted the fact. He came to Chicago because he knew more people here and was certain of getting morphine.
