Having dwelt so much on this first and leading error in respect to opium, I shall notice very briefly a second and a third; which are, that the elevation of spirits produced by opium is necessarily followed by a proportionate depression, and that the natural and even immediate consequence of opium is torpor and stagnation, animal and mental. The first of these errors I shall content myself with simply denying; assuring my reader that for ten years, during which I took opium at intervals, the day succeeding to that on which I allowed myself this luxury was always a day of unusually good spirits.

With respect to the torpor supposed to follow, or rather (if we were to credit the numerous pictures of Turkish opium-eaters) to accompany the practice of opium-eating, I deny that also. Certainly, opium is classed under the head of narcotics, and some such effect it may produce in the end, but the primary effects of opium are always, and in the highest degree, to excite and stimulate the system. This first stage of its action always lasted with me, during my novitiate, for upward of eight hours, so that it must be the fault of the opium-eater himself if he does not so time his exhibition of the dose (to speak medically) as that the whole weight of its narcotic influence may descend upon his sleep.

Thus I have shown that opium does not, of necessity, produce inactivity or torpor. On the contrary it often led me into markets and theatres. Yet, in candor, I will admit that markets and theatres are not the appropriate haunts of the opium-eater when in the divinest state incident to his enjoyment. In that state crowds become an oppression to him; music, even, too sensual and gross. He naturally seeks solitude and silence as indispensable conditions of those trances, or profoundest reveries, which are the crown and consummation of what opium can do for human nature.
