As to opium, it is foul and accursed. God protect us from the punishment He inflicteth on the user. According to the explicit Text of the Most Holy Book, it is forbidden, and its use is utterly condemned. Reason showeth that smoking opium is a kind of insanity, and experience attesteth that the user is completely cut off from the human kingdom. May God protect all against the perpetration of an act so hideous as this, an act which layeth in ruins the very foundation of what it is to be human, and which causeth the user to be dispossessed for ever and ever. For opium fasteneth on the soul, so that the user’s conscience dieth, his mind is blotted away, his perceptions are eroded. It turneth the living into the dead. It quencheth the natural heat. No greater harm can be conceived than that which opium inflicteth. Fortunate are they who never even speak the name of it; then think how wretched is the user.
