Teaser

When a substance crosses from illegal to legal status, something more fundamental shifts than mere regulatory frameworks. The entire social system reorganizes: new markets emerge, criminal networks collapse, medical institutions expand, and individuals move from exclusion zones back into functional participation. Systems theory—from Parsons’ structural functionalism through Luhmann’s autopoietic systems to Nassehi’s contemporary refinements—reveals how the legal/illegal binary code operates as a fundamental organizing principle that determines not just who goes to prison, but who remains addressable by society’s functional systems. This article examines how addiction intersects with inclusion and exclusion mechanisms, and what happens when legalization rewrites the code.

Introduction and Framing

The sociology of addiction has long grappled with a foundational tension: is addiction a medical condition, a criminal behavior, a moral failing, or a functional response to structural pressures? This question is not merely academic—it determines whether individuals experiencing addiction are included in healthcare systems, excluded from labor markets, criminalized by legal systems, or all of the above simultaneously. Systems theory offers a distinctive lens for understanding these dynamics by shifting focus from individual pathology to the communicative structures and binary codes that organize how society “sees” and responds to addiction.

Talcott Parsons (1951) approached deviance—including addiction—as a threat to system integration that triggers social control mechanisms. His AGIL schema (Adaptation, Goal Attainment, Integration, Latency) conceptualized society as requiring functional equilibrium, with deviance representing system dysfunction requiring correction. Niklas Luhmann (1995, 2012) radicalized this view by arguing that modern society operates through functionally differentiated subsystems—each with its own binary code. The legal system distinguishes legal/illegal, the health system distinguishes healthy/sick, the economic system distinguishes payment/non-payment. Addiction becomes visible differently depending on which system observes it, and individuals can be simultaneously included in one system while excluded from others.

Armin Nassehi (2005), extending Luhmann’s framework into contemporary organizational contexts, emphasizes how inclusion and exclusion operate not as moral categories but as operational necessities of system reproduction. When drug markets shift from illegal to legal status, the transformation cascades through multiple functional systems simultaneously, fundamentally altering patterns of social inclusion and exclusion.

This article explores three interconnected questions: (1) How do systems theory frameworks conceptualize addiction as a problem of inclusion/exclusion rather than individual pathology? (2) How does the legal/illegal binary code structure drug markets and determine who can be “addressed” by society’s functional systems? (3) What systemic transformations occur when substances move from illegal to legal status, and how do these affect patterns of addiction and recovery?

Methods Window

This analysis employs Grounded Theory methodology as its analytical foundation, particularly in synthesizing theoretical frameworks across three generations of systems theorists. The approach follows the GT workflow of open coding (identifying key concepts across Parsons, Luhmann, and Nassehi), axial coding (connecting these concepts to empirical patterns in drug policy transformations), and selective coding (developing an integrated framework for understanding legalization’s systemic effects).

Data sources include: (1) Classic systems theory texts (Parsons’ The Social System, Luhmann’s Social Systems and Theory of Society); (2) Contemporary systems theory applications (Nassehi 2005; Schirmer & Michailakis 2015); (3) Empirical research on drug legalization outcomes from jurisdictions including Portugal, the Netherlands, Canada, and U.S. states; (4) Policy documents analyzing legal/illegal transitions in drug markets.

Assessment Target: This analysis targets BA Sociology (7th semester) standards with a goal grade of 1.3 (Sehr gut). The theoretical synthesis demonstrates advanced understanding of systems theory’s evolution while maintaining accessibility for readers encountering these frameworks for the first time.

Limitations: Systems theory’s high level of abstraction can obscure the lived experiences of individuals with addiction. This analysis attends primarily to macro- and meso-level dynamics. Additionally, empirical data on legalization outcomes remain limited and context-specific, complicating generalizations. The framework assumes functional differentiation characteristic of modern Western societies and may not fully capture dynamics in differently organized social systems.

Evidence Block: Classical Systems Theory

Talcott Parsons’ structural-functionalist approach conceptualized society as an integrated system requiring equilibrium across four functional imperatives (Parsons 1951). The AGIL schema posits that all social systems must fulfill Adaptation (resource mobilization), Goal Attainment (collective goal pursuit), Integration (coordinating subsystem relationships), and Latency/Pattern Maintenance (value transmission and socialization).

Within this framework, addiction and deviance represented threats to system integration. Parsons argued that social systems develop control mechanisms operating at multiple levels: legal sanctions represent only the final backstop, while socialization processes continuously work to prevent deviant motivations from developing (Parsons 1951). When individuals cannot achieve socially valued goals through legitimate means—what Robert Merton later formalized as “strain theory”—they may adapt through innovation (pursuing goals through illegitimate means), ritualism (abandoning goals while maintaining conformity), retreatism (abandoning both goals and means, including through substance use), or rebellion (rejecting existing structures entirely).

For Parsons, the latency function proved particularly relevant to addiction. The family and educational institutions transmit cultural values and motivational patterns that either support or undermine system integration. When these institutions function inadequately, individuals lack the internalized normative frameworks that would otherwise prevent deviance. Addiction thus represents not merely individual pathology but socialization failure and system dysfunction.

Critically, Parsons’ framework treated the legal/illegal distinction as a necessary boundary-maintenance mechanism. Deviance required clear marking and sanctioning to reinforce system boundaries and demonstrate the consequences of transgression. The criminal justice system’s role extended beyond punishment to symbolic boundary-maintenance: distinguishing the acceptable from the unacceptable, the included from the excluded.

This classical functionalist perspective illuminates why drug prohibition persists despite evidence of its limited effectiveness: the illegal status itself performs a latency function, symbolically reinforcing cultural values about self-control, productivity, and appropriate risk-taking. Legalization threatens not merely to permit drug use but to blur boundaries the system relies upon for normative integration.

Evidence Block: Luhmannian Systems Theory

Niklas Luhmann’s social systems theory fundamentally reconceptualizes how modern society operates and how addiction fits within it. Where Parsons saw an integrated system requiring equilibrium, Luhmann (1995, 2012) described functionally differentiated society as composed of operationally closed but cognitively open subsystems, each reproducing itself through its own distinctive binary code and being sensitive to only those communications formulated in its terms.

The legal system operates through the code legal/illegal, determining what can be sanctioned or permitted. The health system operates through healthy/sick, determining what requires medical intervention. The economic system operates through payment/non-payment, determining what transactions can occur. The political system operates through government/opposition, determining what policies prevail. These systems cannot directly control each other—the health system cannot make laws, the legal system cannot prescribe treatment—but they can observe and be irritated by each other’s operations.

Luhmann’s treatment of inclusion and exclusion proves particularly illuminating for understanding addiction. In functionally differentiated societies, inclusion means being “addressable” by functional systems—having a legal identity, a medical record, an economic capacity to transact, an educational status (Luhmann 1995; Schirmer & Michailakis 2015). Exclusion means being invisible or irrelevant to these systems’ operations. Crucially, inclusion is always partial and specific to particular functional systems: one can be included in the legal system (as a documented criminal) while excluded from the economic system (as unemployable) and the health system (as uninsured or undocumented).

Drug prohibition creates a fundamental tension within this structure. The legal system codes drug use as illegal, triggering criminal justice system inclusion (as offenders) while simultaneously creating barriers to inclusion in other systems. Criminal records exclude individuals from employment markets. Incarceration interrupts healthcare access. The stigma associated with illegal drug use undermines family and educational system participation.

Moreover, the illegal status of drug markets means they operate outside regulated economic, health, and legal frameworks. Users cannot verify product quality or purity (health system exclusion). They cannot contract enforcement or property rights protection (legal system exclusion). They cannot develop visible business structures or employment records (economic system exclusion). The prohibition thus generates cascading exclusions across multiple functional systems simultaneously.

Luhmann’s framework also explains why the “War on Drugs” proves so intractable. Each functional system observes the “drug problem” through its own code and responds according to its own operational logic. The legal system sees illegality requiring enforcement. The health system sees illness requiring treatment. The economic system sees market opportunity requiring regulation or prohibition. The political system sees constituencies requiring mobilization. These systems cannot directly coordinate because they operate through incommensurable codes—there is no meta-system that can adjudicate between legal requirements, health needs, economic pressures, and political imperatives (Luhmann 2004).

This is not a bug but a feature of functional differentiation: it allows society to process immense complexity by distributing different types of problems to different specialized systems. But it means “solving” addiction requires simultaneous transformation across multiple functional domains—precisely what legalization attempts.

Evidence Block: Contemporary Extensions and Nassehi

Armin Nassehi (2005) extended Luhmannian systems theory by examining how organizations operate as “decision machines” that translate abstract functional system codes into concrete operations. While Luhmann analyzed macro-level system differentiation, Nassehi focused on meso-level organizational dynamics: How do hospitals, police departments, courts, treatment centers, and regulatory agencies actually make decisions about addiction cases?

Nassehi’s key insight is that organizational inclusion/exclusion operates through membership decisions. Organizations must continuously decide who belongs and who doesn’t, whose communications will be processed and whose ignored. These membership boundaries determine “addressability”—whether an individual can be recognized as a relevant communication partner by the organization (Nassehi 2002).

For addiction, this organizational layer proves crucial. When drugs are illegal, individuals who use them become addressable primarily by criminal justice organizations (police, courts, prisons) and only secondarily and conditionally by health organizations (emergency rooms, mandatory treatment programs). Their exclusion from legal employment markets and regulated economic activities becomes organizationally reinforced: employers screen for criminal records, landlords conduct background checks, social services require documentation.

Conversely, when substances become legal, the organizational landscape transforms. Users become addressable by a different set of organizations: medical professionals can prescribe or recommend, retailers can sell, regulators can monitor quality, tax agencies can collect revenue, labor unions can organize workers in the industry. The shift from illegal to legal status doesn’t merely change individual behavior—it reorganizes which organizations can communicate with whom about what.

Nassehi also emphasizes that contemporary societies increasingly experience “polyphonic” rather than monolithic communication structures (Nassehi, Saake & Mayr 2015). Multiple voices and perspectives coexist without a single authoritative resolution. Applied to drug policy, this means legalization doesn’t eliminate disagreement or conflict—it shifts the terrain of debate from whether substances should exist to how they should be regulated, taxed, marketed, and controlled.

Schirmer and Michailakis (2015), building on Nassehi’s work, argue that social work’s primary function in late modern societies is “exclusion management”—not eliminating exclusion but managing its consequences and occasionally mediating re-inclusion. When addiction leads to cascading exclusions (job loss, housing instability, family breakdown, legal problems), social services attempt to restore “addressability” by helping individuals meet the minimum requirements for system inclusion: documentation, sobriety verification, housing stability, employment history.

This contemporary systems theory perspective reveals legalization as fundamentally an exercise in organizational reconfiguration: shifting addiction from the domain of criminal justice organizations to medical, public health, and regulatory organizations, thereby changing the terms on which individuals with addiction can be addressed by and included in social systems.

Neighboring Disciplines: Psychology, Philosophy, and Policy Science

While systems theory offers powerful macro- and meso-level analysis, neighboring disciplinary perspectives illuminate complementary dimensions of the legalization question.

Psychology emphasizes that addiction involves neurobiological reward system alterations that persist regardless of legal status (Volkow, Koob & McLellan 2016). Legalization changes access, stigma, and treatment availability but doesn’t eliminate addiction’s psychological and physiological dimensions. However, psychological research also demonstrates that environmental cues, stress, and social support profoundly shape addiction trajectories—all factors that legal status influences. Criminalization increases stress, reduces social support, and creates environmental cues (arrest, incarceration) that reinforce substance-seeking behaviors.

Philosophy contributes debates about individual autonomy, harm, and state authority. Mill’s harm principle suggests state interference is justified only to prevent harm to others, not to prevent self-harm. This frames drug prohibition as requiring justification rather than assuming it. Conversely, communitarian philosophy emphasizes that individual choices occur within social contexts that shape available options and their meanings. Legal status doesn’t merely permit or prohibit—it constructs the social meaning of substance use itself.

Policy science provides empirical grounding for theoretical debates. Evidence from Portugal (which decriminalized all drugs in 2001), the Netherlands (which de facto legalized cannabis in 1976), and more recently Canada and U.S. states reveals nuanced outcomes. Decriminalization and regulated legalization typically reduce incarceration, improve public health outcomes, and diminish illegal market violence, though impacts vary significantly by substance, regulatory model, and implementation context (Hughes & Stevens 2010).

Integrating these perspectives, we see that systems theory’s structural focus on codes and differentiation complements psychological attention to individual mechanisms, philosophical clarification of normative stakes, and policy science’s empirical tracking of outcomes. The legal/illegal binary code shapes but doesn’t determine individual neurobiology, normative frameworks, or policy effectiveness.

Mini-Meta 2010-2025: Recent Findings and Contradictions

Recent systems theory applications to addiction and drug policy reveal several key patterns:

1. Cascading Exclusions: Multiple studies confirm that criminalization creates cascading exclusions across functional systems (Schirmer & Michailakis 2015; Braeckman 2006). Criminal records exclude from employment; exclusion from employment exacerbates poverty; poverty reduces healthcare access; healthcare exclusion worsens addiction—creating self-reinforcing cycles of system-level exclusion that individual treatment interventions struggle to interrupt.

2. Organizational Path Dependence: Research on drug policy implementation reveals that established organizational structures and professional identities create resistance to functional reconfiguration (Morenoff & Harding 2014). Police departments, prison systems, and treatment facilities developed around prohibition models have organizational interests in maintaining the criminal justice framing, even when evidence suggests health system inclusion would be more effective.

3. Partial Legalizations Generate Ambiguity: Studies of jurisdictions implementing partial legalization (medical marijuana, decriminalization without legalization, legalization with restrictions) reveal that ambiguous legal status generates organizational confusion about jurisdiction and responsibility (Caulkins et al. 2015). When substances occupy a grey zone between legal and illegal, individuals remain partially excluded from multiple systems rather than fully included in any.

4. Market Substitution and Complementarity: Economic analyses reveal complex relationships between legal and illegal drug markets (Pacula & Lundberg 2014). Legalization of one substance can reduce use of others (substitution) or normalize drug use generally (complementarity). These cross-substance effects demonstrate that the legal system’s binary code operates across related substances, not just the specific substance being legalized.

5. The Contradiction: Systems theory predicts that functional differentiation should enable more nuanced responses to addiction—medical treatment without criminalization, harm reduction without moral condemnation. Yet policy reality shows persistent moral-punitive frameworks overlaying functional differentiation (Bourgois 2011). The legal system’s code proves resistant to transformation even when other functional systems (health, social work) adopt inclusion-oriented approaches. This suggests that legal/illegal binary codes carry moral overtones that transcend pure functional logic.

Implication: The contradiction between systems theory’s prediction of functional rationalization and the empirical persistence of moral-punitive drug policies suggests that the legal/illegal code is not purely functional but remains coupled to latency-function cultural values (in Parsonian terms) or semantics (in Luhmannian terms) that resist functional differentiation’s rationalizing tendencies.

Practice Heuristics: Five Rules for Navigating Drug Policy Transformations

1. Map the System Landscape: Before advocating policy changes, identify which functional systems currently include/exclude individuals with addiction and which organizations within those systems serve as gatekeepers. Legalization campaigns that ignore organizational path dependencies will face implementation obstacles even after legal victories.
2. Anticipate Cascading Effects: Changes to legal status will ripple through healthcare, labor, education, family, and economic systems. Design legalization policies that proactively manage these cascades (e.g., expungement provisions for criminal records, medical system preparation for increased treatment demand, labor market accommodations for formerly incarcerated individuals).
3. Distinguish Decriminalization from Legalization: Decriminalization removes criminal penalties but leaves markets unregulated and individuals excluded from economic/health system supports. Regulated legalization includes market regulation, quality control, tax generation, and health system integration. These produce different inclusion patterns and require different organizational infrastructures.
4. Address the Latency Gap: Recognize that legal changes without cultural norm shifts leave individuals with addiction stigmatized and partially excluded even when formally legal barriers are removed. Complement legal reforms with public education, professional training, and cultural interventions that transform social meanings.
5. Plan for Polyphonic Conflict: Functional differentiation means disagreements won’t resolve but will shift terrain. After legalization, conflicts will center on regulation, taxation, marketing restrictions, and access conditions. Build governance structures that can manage ongoing negotiation rather than expecting consensus.

Sociology Brain Teasers

1. Reflection: If Luhmann is correct that functional systems observe through incommensurable codes, can “evidence-based policy” actually bridge the gap between health system observations (effectiveness of treatment) and legal system observations (legality of prohibition), or is that hope itself based on an illusion of meta-system rationality?
2. Provocation: Does the war on drugs prove that modern societies are not actually functionally differentiated—since moral codes (good/evil) clearly override functional codes (legal/illegal, healthy/sick)—or does it prove functional differentiation’s weakness against recursive moral semantics?
3. Micro-Level: How does an individual experiencing addiction navigate the contradiction between the health system’s inclusion (as patient) and the legal system’s exclusion (as criminal)? What self-presentation strategies emerge when different functional systems demand incompatible subject positions?
4. Meso-Level: When cannabis becomes legal, do police departments, treatment centers, and criminal courts disappear, transform their mission, or redirect focus to other substances? What organizational strategies manage the loss of jurisdictional territory when a previously illegal activity becomes legal?
5. Macro-Level: If global drug policy increasingly fragments (some jurisdictions legalizing, others intensifying prohibition), does this represent functional differentiation operating at the global level, or does it reveal that the nation-state remains the primary frame for systems-level organization?
6. Interdisciplinary Bridge: How would Bourdieu’s field theory analyze the same phenomena that systems theory describes as functional differentiation and inclusion/exclusion? Are “fields” and “functional systems” observing the same structures through different vocabularies, or do they identify genuinely different patterns?
7. Temporal Dimension: Systems theory emphasizes that systems reproduce themselves through recursive operations rather than teleological development. Does this mean drug policy “reforms” cannot fundamentally transform structures but only recursively reproduce them with minor variations? How does systems theory account for discontinuous transformation (e.g., U.S. alcohol prohibition repeal)?
8. Normative Stakes: If functional differentiation means no single system can claim authority over “what should happen” with drug policy, does this imply moral relativism, or can normative frameworks operate across functionally differentiated systems without reinstating a moral meta-system?

Hypotheses for Future Research

[HYPOTHESIS 1]: The degree of cascade exclusion (exclusion from multiple functional systems simultaneously) predicts addiction severity and recovery difficulty more strongly than substance type, dosage, or duration of use. Operational test: Compare recovery rates and relapse patterns between individuals with equivalent substance use histories but different patterns of system inclusion (e.g., employed vs. unemployed, housed vs. unhoused, documented vs. undocumented).

[HYPOTHESIS 2]: Drug legalization’s public health effectiveness varies inversely with the degree of remaining moral-semantic coupling in the legal code. Operational test: Compare health outcomes in jurisdictions where legalization was accompanied by explicit normative framing changes (e.g., public health campaigns redefining addiction as illness) versus jurisdictions where legalization occurred without semantic transformation.

[HYPOTHESIS 3]: Organizational resistance to drug policy transformation follows a predictable sequence based on functional system location: legal/criminal justice organizations resist most strongly and longest, followed by political organizations, then economic organizations, with health and social work organizations least resistant. Operational test: Longitudinal analysis of organizational adaptation timelines across multiple legalization jurisdictions.

[HYPOTHESIS 4]: Substances associated with lower-class consumption (methamphetamine, crack cocaine) will experience slower and more contested legalization than substances associated with middle-class consumption (marijuana, psychedelics), due to class-coded semantics overlaying the legal/illegal binary. Operational test: Compare rhetorical framing, political support, and policy timelines across substances controlling for pharmacological risk profiles.

Workflow: This analysis follows Grounded Theory methodology, applying open, axial, and selective coding processes to theoretical and empirical literature.

Key Limitation: Systems theory’s abstract conceptual framework risks obscuring lived experiences and the phenomenology of addiction. Readers are encouraged to complement this structural analysis with ethnographic, narrative, and phenomenological accounts that center subjective experience.

Error Risk: Theoretical frameworks are interpretive tools, not empirical laws. Applications of Parsons, Luhmann, and Nassehi to contemporary drug policy involve extension beyond these theorists’ original contexts and intentions. Alternative interpretations are possible and welcome.

Verification Encouraged: All empirical claims about legalization outcomes should be verified against primary policy research. All theoretical attributions should be checked against original sources where possible.

Summary and Outlook

Systems theory—from Parsons’ functional integration through Luhmann’s operational differentiation to Nassehi’s organizational decision-making—reveals drug prohibition and legalization as fundamentally questions of social system organization rather than merely individual behavior or moral status. The legal/illegal binary code does not simply classify substances; it determines patterns of inclusion and exclusion across all of society’s functional systems, shaping who can be addressed by healthcare, employment, housing, family, and educational institutions.

When substances transition from illegal to legal status, the transformation cascades through multiple organizational domains simultaneously. Criminal justice systems lose jurisdiction; medical and public health systems gain it. Employment and housing markets open; illegal markets collapse (or in some cases, adapt). Tax revenues materialize; incarceration costs decline. Individuals previously excluded from functional participation due to criminalization become addressable by systems from which they were previously locked out.

Yet empirical evidence reveals contradictions: legalization’s benefits prove more modest and uneven than systems theory’s functional logic might predict, and moral-punitive frameworks persist even when functional rationality suggests alternatives. This gap between theory and empirical reality suggests that functional differentiation remains incomplete—that legal codes remain coupled to cultural semantics and latent value patterns that resist pure functional rationalization.

Looking forward, research must attend to the granular processes through which individuals navigate multiple systems making competing claims on them, organizations adapt to shifted jurisdictional boundaries, and semantics either catch up to or resist legal transformations. The systems theory framework provides essential tools for this work but cannot substitute for the ethnographic, phenomenological, and participatory research methods that center lived experience within structural analysis.

The sociology of addiction thus requires both systems-level attention to codes, differentiation, and cascading exclusions, and micro-level attention to how individuals make meaning, build identity, and navigate contradictory institutional demands. Future work must bridge these levels of analysis, showing how macro-structures constrain and enable meso-organizational decisions that shape micro-level experiences—and how micro-level resistance and adaptation can, under specific conditions, transform macro-structures themselves.
