The traditional rôle of alcohol is that of a stimulant. It has been supposed to stimulate digestion and assimilation; to stimulate the heart's action; to stimulate muscular activity and strength; to stimulate the mind. The new evidence seems to show that, in the final analysis, alcohol stimulates none of these activities; that its final effect is everywhere depressive and inhibitory (at any rate, as regards higher functions) rather than stimulative; that, in short, it is properly to be classed with the anesthetics and narcotics. The grounds for this view should be of interest to every user of alcohol; of interest, for that matter, to every citizen, considering that more than one thousand million gallons of alcoholic beverages are consumed in the United States each year. I should like to present the new evidence far more fully than space will permit. I shall attempt, however, to describe some of the more significant observations and experiments in sufficient detail to enable the reader to draw his own conclusions. To make room for this, I must deal with other portions of the testimony in a very summary manner. As regards digestion, for example, I must be content to note that the experiments show that alcohol does indeed stimulate the flow of digestive fluids, but that it also tends to interfere with their normal action; so that ordinarily one effect neutralizes the other. As regards the action on the heart, I shall merely state that the ultimate effect of alcohol is to depress, in large doses to paralyze, that organ. These, after all, are matters that concern the physician rather than the general reader. The effect of alcohol on muscular activity has a larger measure of popular interest; indeed, it is a question of the utmost practicality. The experiments show that alcohol does not increase the capacity to do muscular work, but distinctly decreases it. Doubtless this seems at variance with many a man's observation of himself; but the explanation is found in the fact that alcohol blurs the judgment. As Voit remarks, it gives, not strength, but, at most, the feeling of strength. A man may think he is working faster and better under the influence of alcohol than he would otherwise do; but rigidly conducted experiments do not confirm this opinion. "Both science and the experience of life," says Dr. John J. Abel, of Johns Hopkins University, "have exploded the pernicious theory that alcohol gives any persistent increase of muscular power. The disappearance of this universal error will greatly reduce the consumption of alcohol among laboring men. It is well understood by all who control large bodies of men engaged in physical labor, that alcohol and effective work are incompatible."
