Now, reader, assure yourself, meo periculo, that no quantity of opium ever did or could intoxicate. As to the tincture of opium (commonly called laudanum) that might certainly intoxicate if a man could bear to take enough of it; but why? Because it contains so much proof spirit, and not because it contains so much opium. But crude opium, I affirm peremptorily, is incapable of producing any state of body at all resembling that which is produced by alcohol, and not in degree only incapable, but even in kind: it is not in the quantity of its effects merely, but in the quality, that it differs altogether. The pleasure given by wine is always mounting and tending to a crisis, after which it declines; that from opium, when once generated, is stationary for eight or ten hours: the first, to borrow a technical distinction from medicine, is a case of acute—the second, the chronic pleasure; the one is a flame, the other a steady and equable glow. But the main distinction lies in this, that whereas wine disorders the mental faculties, opium, on the contrary (if taken in a proper manner), introduces amongst them the most exquisite order, legislation, and harmony. Wine robs a man of his self-possession; opium greatly invigorates it. Wine unsettles and clouds the judgement, and gives a preternatural brightness and a vivid exaltation to the contempts and the admirations, the loves and the hatreds of the drinker; opium, on the contrary, communicates serenity
and
equipoise to all the faculties, active or passive, and with respect to the temper and moral feelings in general it gives simply that sort of vital warmth which is approved by the judgment, and which would probably always accompany a bodily constitution of primeval or antediluvian health.
