All unprejudiced authorities are agreed that the habitual use of tobacco acts injuriously upon the system, no matter in what form or manner it is used. It is stated that there is no nicotine in tobacco smoke, that is during the combustion the nicotine is changed chemically, but it is nevertheless true that there are more or less poisonous gaseous compounds in the smoke. Not only is the tobacco habit injurious to the system, but it is also nasty and filthy. The tobacco stench not only permeates the clothing, but also the entire system, the breath and the atmosphere about the users of tobacco. While all tobacco habits are filthy, there are degrees of filthiness. “Snuff dipping,” which is extensively practiced by men and women of the poorer classes of the south, is unquestionably the most filthy habit. A stick moistened with saliva is dipped into snuff tobacco and rubbed on gums, teeth and tongue. Next in filthiness is the old fashion of putting snuff into the nostrils; a habit which we are pleased to note is rapidly dying out. Next follows the chewing habit, which is very extensively practiced by laborers, with whom smoking is inconvenient or forbidden; as sailors. I remember an inveterate user of tobacco who smoked and chewed at the same time; he kept a quid in his mouth during his meals and took a big mouthful just before retiring. The breath of tobacco chewers is sickening, and the discolored teeth and tobacco stained mustache and beard is disgusting to behold, to say nothing of the filthy expectoration. Of the various forms of smoking the cigarette habit is the most disgusting and the most injurious. Cigarettes are extensively smoked by young boys, and those who continue on a large scale become physical and mental weaklings and criminals. Pipe smoking, as already indicated, dates back to remotest antiquity. Pipes with short stems are more injurious because more poisonous volatile substances are inhaled. The long stemmed pipes of German students are less injurious. In a short time the bowl of the pipe becomes saturated with tobacco oil and emits a horrible stench. Cigar smoking is usually considered less vulgar and less disgusting than smoking a pipe, but there is certainly nothing more disagreeable to the nostrils than the conglomerate stench from a poor cigar. The well diluted aroma from a good cigar is very pleasant at a distance.
