In literature, the term "intoxicant" is often employed as a metaphor to represent not just literal substances, but also the overwhelming force of emotion and passion. For instance, in Kate Chopin's work, the description of a character's fervor suggests that her excitement spreads through her like an intoxicant, infiltrating both her blood and brain [1]. This usage illustrates how authors use the word to evoke a sense of total immersion, where emotions become as potent and consuming as any physical vice.
