Alcohol is classed here as a narcotic and not a stimulant, because we shall see later that alcohol is rather a paralyzer of functions, even when it seems to stimulate, than a producer of increased output from any organ. The time honored idea that alcohol is a stimulant and that, if used in moderation, it is a tonic, is so ingrained in the average mind that it is with the greatest difficulty that men can be made to realize that even in what seems moderate doses it may injure them. This is especially true as one sees men who all their lives have indulged moderately in alcoholic beverages from which seemingly no harm has resulted. The truth, perhaps, is best summed up by the old adage that what is one man's meat is another man's poison, and there is no question that the effects of alcohol in small or moderate doses is vastly different from its effects in large doses, or in long continued, excessive use. Different human beings react differently to similar amounts of alcohol, and conversely, identical amounts of alcohol will affect different individuals in different ways, even when it poisons all of them. For instance, if alcohol sets different processes in motion which bring about damage to the individual, we find that in some persons it has injured the heart and arteries, in others it has affected the liver or stomach, leaving the brain and nervous tissues free from damage, while in still others the body in general seems to be untouched and the brain and nervous tissues suffer the injuries. It is not uncommon to see a man who has partaken freely of alcoholic beverages all his life with neither he nor his friends conscious that his intellect has suffered or deteriorated thereby, to find suddenly that his circulatory and digestive systems are seriously and permanently damaged. On the other hand, many a drunkard has become a burden to his family and the community, with his personality deteriorated, his intellect rendered useless, while his circulation and digestion remain unimpaired, and he lives long years a nuisance and a burden to his environment.
