Drugs, Alcohol and Crime

Drugs and alcohol are among the most contested topics in criminology. Substances have been consumed by people in all societies and at all times, whether for ritual, medical, or recreational purposes. What distinguishes modern societies is not the existence of substance use but the way it is classified, regulated, and criminalised. CriminologyThe scientific study of crime, criminal behavior, prevention, and societal reactions to deviance within and beyond the criminal justice system. studies drugs and alcohol because of their links to deviance, violence, organised crime, public health, and social control. Few areas illustrate more clearly how law, morality, and politics intersect.

Key Points

Historical and Sociological Perspectives

In early modern societies, alcohol, cannabis, and opium were widely used and often embedded in cultural or medical practices. The first comprehensive attempts to regulate drugs emerged in the nineteenth century, but they were motivated less by health concerns than by economic and political interests. The Opium Wars of 1839–1860 between Britain and China are emblematic: rather than protecting public health, imperial powers fought to secure profitable markets for the opium trade. Drug regulation was thus closely tied to colonialism, geopolitics, and economic competition.

By the early twentieth century, the prohibitionist framework became institutionalised through national laws and international treaties. The United States played a key role with the Harrison Narcotics Tax Act (1914) and later the “War on DrugsGovernment-led campaign aiming to reduce drug use and trade through criminalization and policing.,” which globalised punitive approaches. Alcohol prohibition in the U.S. during the 1920s demonstrated both the ambitions and contradictions of prohibitionist policy: while consumption initially declined, organised crime flourished, and alcohol quickly regained legality. Similar dynamics can be observed with other substances, where patterns of prohibition reflect political priorities, moral panics, and lobbying pressures more than scientific evidence of harm.

Sociological theories help explain these developments. Howard Becker’s labelling theory and Stanley Cohen’s concept of moral panics highlight how certain substances and their users are constructed as deviant “folk devils.” Critical criminologists stress that drug prohibition serves not only as crime control but also as social regulation, disproportionately affecting marginalised communities. Indigenous perspectives add another dimension, showing how traditional uses of coca, peyote, or ayahuasca were criminalised under colonial and global control regimes, raising questions of cultural rights and global inequalities.

Drug Use Worldwide: Prevalence and Trends

Global data on drug use are systematically collected and published by the United Nations Office on Drugs and CrimeActs or omissions that violate criminal laws and are punishable by the state. (UNODC) in its annual World Drug Report. According to the most recent figures,
around 292 million people worldwide (roughly 1 in 19 adults aged 15–64) used drugs at least once in 2023.
The majority of users consume cannabis, with an estimated 219 million users, making it by far the most prevalent illicit drug globally. Other major categories include opioids (about 60 million users, including heroin and synthetic opioids such as fentanyl), amphetamine-type stimulants (ATS) (30 million), cocaine (22 million), and ecstasy/MDMA (20 million).

Patterns vary by region. While cannabis dominates in North America and Europe, opioids account for the largest share of drug-related health harms worldwide, including the highest rates of dependency and overdose. Cocaine use continues to rise in parts of the Americas and Europe, while methamphetamine and other ATS are increasingly prevalent in Asia and Oceania. These trends highlight that global drug use is shaped not only by individual choices but also by economic, cultural, and political contexts.

Complementary insights are provided by the Global Drug Survey (GDS), which, although not representative, captures emerging trends and consumption patterns among self-selected users worldwide. The GDS often identifies new substances, practices, and harm-reduction strategies earlier than official statistics, making it a valuable addition to the global monitoring landscape.

Drugs, Alcohol, and Crime

The relationship between drugs, alcohol, and crime is multifaceted. On the most direct level, criminal law defines the possession, use, and sale of certain substances as offences. Beyond this, substance use is associated with a variety of crime types. Intoxication, especially through alcohol, is linked to violent offences ranging from domestic violence to street fights. Dependence on expensive illicit drugs, such as heroin or cocaine, can fuel property crimes, as individuals seek resources to finance their use. At a systemic level, the illicit drug trade sustains organised crime networks, fuels corruption, and shapes transnational flows of money and power. Even the legal drug markets, particularly alcohol and pharmaceuticals, are intertwined with crime through regulatory breaches, tax evasion, and corporate lobbying.

Theoretical Approaches

Explanations for the nexus between drugs, alcohol, and crime draw on multiple disciplinary traditions. Biological and psychopharmacological perspectives emphasise how substances alter brain chemistry, lowering inhibitions or increasing aggression. Psychological models explore addiction, impulse control, and cognitive distortions. Sociological theories, in contrast, situate drug-related crime within broader structures: Robert Merton’s strain theory explains how limited opportunities for success push individuals toward deviant adaptations, while subcultural theories describe how drug use can become part of collective identities and lifestyles. Labelling perspectives stress that the stigma of being marked a “drug user” can entrench deviance. Political economy and critical criminology highlight that prohibition creates illicit markets and justifies extensive policing, surveillance, and incarceration.

Another dimension is the medicalisation of drug use. Since the late twentieth century, addiction has increasingly been framed as a brain disease rather than a moral failing, shifting the focus toward treatment and public health. This shift coexists, however, with punitive policies, producing tensions between medical and criminal justice approaches.

GenderSocial and cultural roles, behaviors, and expectations linked to masculinity and femininity. also matters: women are often doubly stigmatised as users and as mothers, facing barriers to treatment and harsher social judgments. Intersectional approaches highlight how drug policy affects women, minorities, and the poor in specific and unequal ways.

Policy Approaches

Drug policy has oscillated between prohibitionist regimes and more liberal harm-reduction strategies. Prohibition, with its emphasis on criminal penalties, has produced unprecedented levels of imprisonment, particularly in the United States. The so-called War on Drugs since the 1970s led to soaring incarceration rates, disproportionately targeting minorities and the poor, while failing to eliminate drug markets.

In contrast, harm reduction reframes substance use as primarily a health issue. Examples include drug consumption rooms, substitution treatment, and needle exchange programmes. Portugal offers one of the most influential case studies: since 2001, the personal use of all drugs has been decriminalised. Instead of criminal penalties, individuals found with small amounts are referred to “dissuasion commissions” that provide counselling, treatment, or social support. Evaluations show reductions in drug-related deaths, lower HIV infection rates, and no significant rise in consumption. The Portuguese experience suggests that punitive approaches are not the only option, and that social and health policies can be more effective in reducing harm.

A more recent development is the psychedelic renaissance. Clinical trials on psilocybin, MDMA, and LSD suggest therapeutic potential for depression, PTSD, and addiction. These findings challenge prohibitionist paradigms and raise questions about how science, medicine, and policy interact in shaping drug control.

Contemporary Debates

Today’s debates on drugs, alcohol, and crime are shaped by conflicting evidence, moral values, and political interests. One key issue concerns the effectiveness of prohibition. Despite decades of “wars on drugs,” illicit markets remain resilient, while mass incarceration has deepened social inequalities. Critics argue that drug policy often reflects punitive populism rather than scientific evidence.

The work of David Nutt and colleagues (2010) has been influential in demonstrating this disconnect. Using a multi-criteria analysis, they showed that alcohol ranks among the most harmful substances overall—more damaging than many illegal drugs such as cannabis, ecstasy, or LSD. The persistence of alcohol’s legality, alongside the prohibition of less harmful substances, reveals how cultural traditions, political lobbying, and economic interests outweigh public health evidence in shaping policy.

Another important dimension is inequality in enforcement. Stop-and-search practices, racial profiling, and disproportionate sentencing demonstrate that drug laws are not applied equally. In the Global South, the “war on drugs” has contributed to violence, corruption, and the militarisation of policing, while consumption patterns in the Global North continue to drive demand. Global supply chains—from coca production in Latin America to meth labs in Southeast Asia—show how drug economies are deeply transnational, linking local communities to global markets.

At the same time, new cultural contexts highlight the ambivalence of drugs and alcohol. Substances are central to youth cultures, nightlife economies, and music scenes, often celebrated as sources of pleasure and identity but also stigmatised as gateways to crime. Alcohol in particular illustrates this duality: while socially accepted, it is associated with significant levels of violence and health harm.

Another recurrent argument in drug policy is the so-called “gateway drug” hypothesis, often associated with cannabis. According to this claim, cannabis use inevitably leads to the consumption of “harder” drugs such as heroin or cocaine. However, empirical research suggests that this argument is highly misleading. It is true that most heroin users have at some point used cannabis, but this does not imply causality. The overwhelming majority of cannabis users worldwide never progress to using heroin or other hard drugs. The gateway effect is therefore better understood as a statistical correlation shaped by social and market contexts, rather than as a pharmacological inevitability.

One striking paradox of contemporary drug policy is the exceptional status of psychoactive substances compared to other risky behaviours. In most areas of life, liberal democracies emphasise individual responsibility and allow citizens to make choices that affect their health, even when these choices may be harmful. People are free to consume fast food, sugar, or alcohol to excess, despite well-documented risks for public health systems. Drugs, however, are treated differently: their consumption becomes a matter of state control, surveillance, and criminalisation. This discrepancy raises fundamental questions about why drug use is singled out for prohibition, while other equally or more harmful behaviours remain largely regulated through information, taxation, or consumer protection rather than criminal law.

The current Fentanyl crisis in North America illustrates the unintended consequences of prohibitionist drug policies. Fentanyl and its analogues are extremely potent synthetic opioids, responsible for tens of thousands of overdose deaths each year. Yet this phenomenon is not an inevitable feature of drug use itself but largely a product of restrictive policies. Without the prohibition of opium and heroin, and without the supply shortages created by the global War on Drugs, there would be little incentive for illicit markets to shift towards such high-risk substances. Public health experts argue that if states provided regulated access to safer alternatives—such as diamorphine (medical heroin) for dependent users—the demand for fentanyl would diminish, and many deaths could be prevented. This example underlines how prohibition can exacerbate rather than solve the harms associated with drugs, creating dangerous black markets where profit rather than safety determines availability.

At the same time, the rise of digital drug markets—from darknet platforms to cryptocurrencies—has transformed distribution, posing new challenges for policing and regulation. These markets make drugs more accessible while undermining traditional enforcement strategies.

Finally, sociologists and criminologists debate the role of stigma in reintegration. Persistent labelling of drug users as criminals hinders recovery and reintegration, while reintegrative shaming approaches suggest that reducing stigma and supporting community acceptance can lower recidivism and promote public health.

Conclusion

Drugs and alcohol remain central to criminological inquiry because they link biological effects, social behaviour, political choices, and economic structures. They show how deviance is constructed, how laws are justified, and how punishment is distributed. Historical cases such as the Opium Wars, contemporary policy innovations like Portugal’s decriminalisation, and scientific critiques such as those of David Nutt all demonstrate that drug regulation is never neutral. It is a reflection of broader struggles over morality, markets, and state authority.

The challenge for criminology is to critically analyse these dynamics, separating moral panics from evidence-based policy, and to explore ways in which societies can respond to substance use that balance public health, justice, and human rights.
