Meaning: The quote "Nobody will laugh long who deals much with opium: its pleasures even are of a grave and solemn complexion" is from Thomas De Quincey, a British writer best known for his confessional work "Confessions of an English Opium-Eater." This quote reflects De Quincey's personal experience with opium and his belief that the use of the drug ultimately leads to a somber and serious disposition, rather than bringing joy and laughter.

Thomas De Quincey's "Confessions of an English Opium-Eater" is a seminal work in the genre of addiction literature, where the author recounts his struggles with opium addiction and the profound effects it had on his life. In this influential memoir, De Quincey explores the physical and psychological impact of opium use, as well as the complex and often contradictory emotions that accompany it.

The quote itself captures the paradoxical nature of opium's effects. While some may initially seek out the drug for its perceived pleasures, De Quincey suggests that prolonged exposure to opium ultimately leads to a more serious and contemplative state of mind.

By asserting that "Nobody will laugh long who deals much with opium," he seems to caution against the long-term consequences of opium use, suggesting that it can ultimately diminish one's capacity for joy and levity. This reflects the broader cultural and historical understanding of opium as a substance that can lead to addiction, withdrawal, and profound changes in personality and behavior.
