This easy accessibility of drugs in medicinal form is more dangerous than moralists care to admit. The reason why opium-smoking has been, up to the present, less prevalent in the United States than in China and some other countries is probably that the preparation of it and the machinery for taking it are not convenient. If opium-smoking had been generally countenanced in America, if the sale of the pure drug had been for generations permitted here, as it has been in China, if houses for its sale and preparation had been found everywhere, if its social aspects had been considered agreeable, if society had put the stamp of approval upon it, opium-smoking would be as prevalent here as it has been in China. Our human nature is essentially little different from that of the Chinese, but lack of opportunity is everywhere recognized as a great preservative of virtue. Due allowance being made for the difference of moral concepts, our standards of morality and honesty and virtue are certainly no higher than those of the Chinese. Thus, were the conditions the same in both cases, there is no reason to suppose that opium would not be smoked here as much as there; but fortunately it has not yet become thus easy, convenient, and agreeable, and consequently that particular phase of the evil has not yet reached overwhelming proportions. On the other hand, the alkaloids of opium administered hypodermically or as ingredients in many patent medicines _are_ thus convenient, and as a result this phase of the evil _has_ reached overwhelming proportions. Nor have we any cause for congratulation upon our particular form of the vice, for opium-smoking is vastly less vicious than morphine-taking. THE TRAFFIC IN OPIUM
