This article introduces Barbara Kingsolver's 2022 Pulitzer Prize-winning novel Demon Copperhead, focusing on the first-person illness narrative of protagonist Damon Fields and recounting a poor single-parent family teenager's experience with and struggle against opioid addiction. By distinguishing between the concepts of "disease" and "illness," and combining perspectives from medical humanities and cultural studies, it analyzes the economic, cultural, and institutional factors behind the American opioid crisis at individual, regional, and national levels, reflecting on disease stigma and class issues.

1　The Pain of the Individual

This section discusses the sociocultural context of the American opioid abuse crisis. Through Goffman's theory of stigma and Kristeva's concept of "abjection," it explains how drug addicts are constructed as "unclean" bodies subject to moral denigration. Taking Demon Copperhead as its object, it traces protagonist Damon's trajectory: from football star to addict through medical malpractice, to the drug-related deaths of his mother and girlfriend, revealing the structural poverty and family breakdown behind addiction. Damon's internalization of social prejudice and self-identification as "trash" exposes the constraints of Sontag's "illness metaphors" on patients. It examines the hostile environment constituted by school bullying and community indifference, noting how systemic discrimination creates a class predicament where "the weak become weaker." Through comparison with David Copperfield, it critiques the reality of American class rigidity: despite possessing virtue, Damon cannot escape a fated decline, and his open ending reflects the difficulty for marginalized groups to achieve the "American Dream," questioning the failure of individual will before structural violence.

2　The Predicament of the Region

This section discusses the dual dimensions of illness narrative as "symptomatic text" in Demon Copperhead: it presents both the "personal text" of drug addicts' bodily trauma and identity crisis, and the "social text" revealing the structural predicament behind large-scale addiction in Lee County. By tracing the economic transformation of the Appalachian region from tobacco cultivation decline, coal capital monopoly, to industrial structure simplification, it analyzes how government policy errors, widening urban-rural gaps, and lack of workers' rights led marginalized people into poverty and physical-psychological trauma. It notes that against the background of medical discourse's dehistoricization of disease, the novel examines OxyContin dependency within class poverty and social power structures through writing "living bodies," presenting the helplessness of poor people who treat painkillers as "God's gift" due to survival pressure. It also reveals the intergenerational transmission characteristics of drug addiction and the vicious cycle of health workforce shortage and economic decline it causes, critiquing the one-sided cognition that reduces addiction simply to individual moral failure.

3　The Tragedy of the System

This section explores Demon Copperhead's profound critique of the capitalist medical system, revealing the institutional tragedy under the symbiotic relationship between capital groups and medical institutions. Through depicting medical institution corruption in Lee County, the plight of ordinary patients facing long waits due to insufficient federal funding, and doctors' micro-power control over patients' bodies through professional information asymmetry, the novel demonstrates structural inequality in the healthcare system. Purdue Pharma packaged OxyContin as a "non-addictive wonder drug," aggressively marketing it through concealing side effects, bribing medical personnel, and offering Hawaiian vacation rewards, while government regulatory agencies, accepting political donations and lobbying, failed in their duties or even became accomplices, together forming a sinful chain linked by "addiction" and "desire." Damon's tragedy—from self-reliant youth to addict—is precisely a microcosm of this deformed system. Meanwhile, the novel also portrays figures like June who resist through refusing prescriptions and organizing petitions, suggesting the important role of resilience, empathy, and community in treating social disease. Kingsolver continues Dickens's tradition of critical realism, giving voice to marginalized groups through illness narrative, embodying literature's capacity to "entertain, touch, and promote change."

4　Conclusion

This section notes that illness mirrors social reality, exposes medical malpractices, and critiques the institutional roots of capitalism and drug addiction.
