The researches of Dr Richardson, F.R.S., are of immense value with regard to the action of tobacco upon the health. He is of opinion that there are no grounds for believing that smoking—of course, we infer, when indulged in with moderation—can produce organic change. Functional disturbances of the heart, brain, and vision, he tells us, may be traced to its excessive use. It is universally, however, admitted that tobacco, like alcohol—in minute doses—arrests oxidation of living tissues, thus checking their disintegration. Dr Richardson, for this reason, justly considers smoking highly injurious to the young, causing impairment of growth.

In the course of an important discussion which took place between Sir Ranald Martin, Mr Solly, Dr Ranking, and other scientific physicians, the following important results were arrived at respecting smoking: (1) That the habit is only prejudicial when carried to excess; (2) that tobacco is innocuous as compared with alcohol, and in no case worse than tea, and by the side of high living, contrasts most favourably. Whether smoking is or is not injurious to health depends principally upon the following conditions: (1) The kind of tobacco smoked; (2) the manner in which it is consumed; (3) the amount of tobacco smoked; and lastly, when it is indulged in. The great object is to obtain a tobacco which possesses the smallest percentage of nicotine. It was formerly believed that the best varieties of Havana and Turkish tobacco were the most innocuous. According, however, to the recent exhaustive researches of Dr George Harley, F.R.S., it appears that the more delicate the aroma of tobacco, the more poisonous it becomes. Dr Harley is also of opinion that ‘Caporal’ tobacco contains least nicotine, and is consequently to be preferred by those desirous of health. Pipes made of clay, and meerschaums—not foul—are, Dr Richardson considers, in a hygienic point of view, superior to cigars and cigarettes. Neither cigars nor cigarettes should ever be smoked near the end, as the nicotine then is discharged into the mouth in larger proportions. M. Melsens, a very distinguished chemist, is of opinion that a plug of cotton-wool saturated with a solution of strong citric or tannic acid should be inserted in the stem of the pipe, cigar, or cigarette holder. By this precaution, the smoke is effectually filtered, ere reaching the mouth, as the nicotine would then be seized by and combined with the acid. Those who object to this plan on account of its trouble, might with advantage place a small piece of plain cotton-wool in the stem of their pipe as a filtering agent. This should on each occasion be removed and replaced by a fresh one. A more convenient, and probably not less effective plug, is a bit of paper crumpled into a soft ball and placed in the bottom of the pipe. It acts as an absorbent of the objectionable juices which might otherwise find their way into the mouth, and can be changed, if the smoker chooses, every time he fills his pipe.

From a review of the scientific testimony and physiological facts bearing upon this subject, we may safely arrive at the following conclusions: (1) That smoking in excess is decidedly an injurious habit, frequently causing dyspepsia, and functional diseases of the heart, brain, and nervous system. (2) That smoking, even when in moderation, is pernicious in early life, also to certain constitutions, and in particular conditions of the body. (3) That in adult life and in ordinary health, no well-ascertained ill effects have been demonstrated as owing their causation to moderate smoking. (4) That the moderate use of tobacco is not only in many cases a harmless luxury, but occasionally, from its soothing and tranquillising influence, a useful adjunct. Smoking, even in the strictest moderation, with some persons of peculiar idiosyncrasies, acts as a poison, and should therefore be avoided, when feelings of discomfort are entailed by its use.

It is impossible to lay down any rule as to the amount of tobacco which may be consumed without a deleterious effect upon the health. What would be moderation to one is often excess to another, according to temperament, habit, and individual peculiarities. Each person ought to be able to judge for himself as to what is moderation. The best time for smoking is undoubtedly after a meal; and the most injurious, on an empty stomach.

In drawing this paper to a close, we cannot do better than by appending the following extract, taken from Mr Dawson’s valuable little work on longevity. On page sixty-nine of How to Prolong Life, when speaking of smoking, Mr Dawson observes: ‘All things taken into account, it is evident that tobacco in excess is certainly prejudicial to good health; in moderation, however, it may be indulged in with comparative impunity; but under any circumstances, it should be known that a man in health is much better without it. How much more so in the case of those who are weakly! Lastly, I desire to impress upon all smokers that moderation in this habit is of no small moment, the ill effects being proportioned to indulgence.’
