What grounded opium so strongly in China was its social side. The Chinese lacked social occupation, and it was not the custom of the country for a man to find it with his friends and family, though no people are more socially inclined. Smoking opium became their chief social activity; they gathered together in the one heated room of the house to gossip over their pipes. We smoke tobacco as the Chinese smoke opium, "for company" and in company. Thus one must provide strong reasons to make a man give it up. He will not do so because it costs him something; he expects to pay for his pleasures. When a man has actually gone to pieces, it is comparatively easy to convince him that he ought to give up what is hurting him; but the average man has not been excessive enough for that, and has never brought himself to the point of serious conscious injury. Even a physician cannot with any certainty tell the average moderate smoker whether tobacco is hurting him. Consequently, if one would make this man stop smoking, especially when he sees that leaving off has caused some people more apparent discomfort than all their smoking did, one's only chance is to make him change his mental attitude. I hope to assist in doing this by calling attention to the fact that tobacco not only prepares the way for physical diseases of all kinds, as any physician will tell you, but also, as long investigation has shown me, for alcoholism and for drug-taking. TOBACCO, ALCOHOL, AND OPIUM The relation of tobacco, especially in the form of cigarettes, and alcohol and opium is a very close one. For years I have been dealing with alcoholism and morphinism, have gone into their every phase and aspect, have kept careful and minute details of between six and seven thousand cases, and I have never seen a case, except occasionally with women, which did not have a history of excessive tobacco. It is true that my observations are restricted to cases which need medical help,--the neurotic temperaments,--but I am prepared to say that for the phlegmatic man, for the man temperamentally moderate, for the outdoor laborer, whose physical exercise tends to counteract the effect of the tobacco and the alcohol he uses--in short, for all men, tobacco is an unfavorable factor which predisposes to worse habits. A boy always starts smoking before he starts drinking. If he is disposed to drink, that disposition will be increased by smoking, because the action of tobacco makes it normal for him to feel the need of stimulation. He is likely to go to alcohol to soothe the muscular unrest, to blunt the irritation, he has received from tobacco. From alcohol he goes to morphine for the same reason. The nervous condition due to excessive drinking is allayed by morphine, just as the nervous condition due to excessive smoking is allayed by alcohol. Morphine is the legitimate consequence of alcohol, and alcohol is the legitimate consequence of tobacco. Cigarettes, drink, opium, is the logical and
