I1 Narcotics in small amounts may be destroyed in the body. 2l Alcohol can not be considered as a nutritious food. 31 Alcohol—by oxidation may use up certain food 158 Anatomy, Physiology, and Hygiene. elements and thus be considered an indirect food. 41 In the hands of physicians it may be used as a medicine. 51 Alcohol can not escape the system except through secretion of skin, kidneys and lungs. 61 Thus it produces serious changes in the tissues, and hastens death. 71 Alcohol diminishes the power of endurance. 81 Alcohol is not a preventative of diseases. 91 No anesthetic should be used except by proper physicians. io1 Tobacco is a dangerous depressant. 111 Our alms-houses and penitentiaries are filled by victims of narcotism. I21 The use of narcotics in any sense is always expensive as well as injurious.
