While much has been written on the effects of excessive smoking on the nervous system little has been said of the good effects of moderate smoking. Every smoker realizes that the soothing effects of tobacco on the nerves is perhaps its most valuable property. Clouston's opinion, already quoted (and none could be better), is that "tobacco exercises a soothing influence when the nervous system is in anyway irritable; it tends to calm and continuous thinking." Fullerton says, "It gives a composure and feeling of well-being which are beneficial to mind and body." Of these facts there can be no doubt because they are matters of common daily observation and experience. Most smokers find a solace and quieting influence from their evening smoke after the worries of a troublesome day which no other agent can give them. The effect produced may be partly psychological but that does not matter. Indeed the strenuousness of life in the age in which we live seems to demand such a help and nothing appears to supply the want so efficiently, so pleasantly, and with less harm, than a quiet smoke. It puts the smoker at peace with himself and at peace with others. Bush found in his investigations on the mental effects of tobacco on college students that there was a temporary loss of ten per cent in mental efficiency in certain faculties of the mind. This is probably true enough though his results are not quite conclusive. On the other hand many men find that they can think more clearly and more consecutively when helped by a smoke. Indeed they smoke when they have a knotty problem to solve. The point need not be argued; all smokers will agree with it. Judged from a psychological standpoint the effects of tobacco are entirely favorable. To the sleepless, the worried, to him who is troubled in mind or vexed in spirit, the pipe or cigar is a never-failing remedy to soothe and cheer. It is the feeling of betterment which it engenders and the spirit of good will which tobacco creates that are responsible for its universal use by men differing widely in grade and condition of life as well as in mental caliber; it reaches the common springs which move humanity; its qualities are those which have made the pipe a symbol of peace and a bond of fellowship and union between man and man from Pole to Pole. From a general summing up of the opinions which have been quoted the question might finally be asked, "Is tobacco on the whole harmful or beneficial to its users?" The answer seems to be this: "Tobacco to the extent used on the average has some slight injurious effects and some slight beneficial effects on the physical system. It is an excellent preservative agent against contagious and infectious disease. Mentally its effects are overwhelmingly beneficial." In every particular case a man must judge for himself, taking account of his individual idiosyncrasies and conditions whether the use of tobacco is beneficial to him or otherwise. REFERENCES
