This is the doctrine of the true Church on the subject of opium: of which Church I acknowledge myself to be the only member--the alpha and omega; but then it is to be recollected that I speak from the ground of a large and profound personal experience, whereas most of the unscientific authors who have at all treated of opium, and even of those who have written expressly on the _materia medica_, make it evident from the horror they express of it that their experimental knowledge of its action is none at all. I will, however, candidly acknowledge that I have met with one person who bore evidence to its intoxicating power such as staggered my own incredulity; for he was a surgeon, and had himself taken opium largely. I happened to say to him, that his enemies (as I had heard) charged him with talking nonsense on politics, and that his friends apologized for him by suggesting that he was constantly in a state of intoxication from opium. Now the accusation, said I, is not _prima facie_, and of necessity an absurd one; but the defense _is_. To my surprise, however, he insisted that both his enemies and his friends were in the right. "I will maintain," said he, "that I _do_ talk nonsense; and secondly, I will maintain that I do not talk nonsense upon principle, or with any view to profit, but solely and simply," said he, "solely and simply--solely and simply," repeating it three times over, "because I am drunk with opium; and that daily." I confess, that the authority of a surgeon, and one who was reputed a good one, may seem a weighty one to my prejudice; but still I must plead my experience, which was greater than his greatest by seven thousand drops a day; and though it was not possible to suppose a medical man unacquainted with the characteristic symptoms of vinous intoxication, yet it struck me that he might proceed on a logical error of using the word intoxication with too great latitude, and extending it generically to all modes of nervous excitement, instead of restricting it as the expression for a specific sort of excitement connected with certain diagnostics. Some people have maintained, in my hearing, that they had been drunk upon green tea; and a medical student in London, for whose knowledge in his profession I have reason to feel great respect, assured me the other day that a patient in recovering from an illness had got drunk on a beefsteak.
