This study examines the militarised approach of the Mexican government in its struggle against organised crime between 2001 and 2016, focusing on the deployment of the armed forces and the implementation of the so-called kingpin strategy. It argues that the removal of cartel leaders, rather than weakening criminal networks, produced fragmentation, diversification, and militarisation within Mexico’s underworld—a process defined here as zetafication. The thesis uses the rise and evolution of Los Zetas as a case study to analyse how a criminal organisation born from army deserters introduced military tactics, hierarchical discipline, and extreme violence into organised crime, transforming the conflict’s character and the state’s response. Drawing on government reports, interviews with Mexican military officers and civilians, and contemporary scholarship, the study situates this phenomenon within Mexico’s political, legal, and socio-economic context, including the influence of U.S. security policy. It concludes that the use of the military as a policing tool produces short-term tactical gains but undermines long-term state stability, erodes public trust, and perpetuates cycles of violence.

Prolonged mandatory immigration detention has become the norm, not the exception. We have arrived at this moment because immigration detention is supposedly exceptional, subject to different constitutional norms than other civil detention. When the Supreme Court first examined a facial due process challenge to mandatory immigration detention in its 2003 decision in Demore v. Kim, immigration detention exceptionalism caused the Court to uphold mandatory detention. Absent from the Court's analysis was an entire body of due process jurisprudence, most of which developed in the 1970s, which questioned the government's purposes behind civil detention and required significant procedural protections in order for the government to deprive a person of liberty. In the wake of Demore, courts considering as-applied challenges to prolonged mandatory detention formulated multi-factor tests as a method of interpreting the statute to avoid unconstitutional detention. These tests provided an important counterweight to immigration detention exceptionalism and predictability for litigants, but most of the factors are irrelevant to a federal district court in deciding whether prolonged detention without a bond hearing violates a detainee's due process rights. Courts have been taking out the scales to engage in due process balancing, but putting the wrong weights on the scales.

Courts are beginning to discard these multi-factor tests and instead applying the Supreme Court's 1976 Mathews v. Eldridge procedural due process test to decide whether prolonged mandatory immigration detention is unconstitutional. The Mathews balancing test, which considers the private interests at stake, the risk of erroneous deprivation, and the government's interests, has been welcomed in immigration law because it encourages courts to first focus on an individual noncitizen's liberty interest. Mathews thus counteracts immigration detention exceptionalism, which focuses exclusively on the government's interest and finds that removable detainees have no liberty interest whatsoever. The Second Circuit Court of Appeals is the first circuit court to shift its test, transitioning to Mathews balancing in 2024 to decide whether mandatory detention was unreasonably prolonged. As a cautionary note, an attempt at transitioning the balancing test led the Eighth Circuit Court of Appeals, in 2024, to reject all forms of balancing, embrace immigration detention exceptionalism, and hold that any length of mandatory detention is acceptable during removal proceedings. This Article argues that courts can make prolonged mandatory immigration detention exceptional by continuing the work of the Second Circuit in applying the Mathews procedural due process balancing test instead of the existing multi-factor tests.

This report presents Amnesty International’s findings from a research trip to southern Florida in September 2025, to document the human rights impacts of federal and state migration and asylum policies on mass detention and deportation, access to due process, and detention conditions since President Trump took office on 20 January 2025. In particular, it focuses on detention conditions at the Krome North Service Processing Center (Krome) and the Everglades Detention Facility, also known as “Alligator Alcatraz”.

This paper investigates the impact of the targeting of key players by law enforcement on the structure, communication strategies, and activities of a drug trafficking network. Data are extracted from judicial court documents. The unique nature of the investigation – which saw a key player being arrested mid-investigation but police monitoring continuing for another year – allows to compare the network before and after targeting. This paper combines a quantitative element where network statistics and exponential random graph models are used to describe and explain structural changes over time, and a qualitative element where the content of wiretapped conversations is analysed. After law enforcement targeting, network members favoured security over efficiency, although criminal collaboration continued after the arrest of the key player. This paper contributes to the growing literature on the efficiency-security trade-off in criminal networks, and discusses policy implications for repressive policies in illegal drug markets.

The internet has revolutionised retail sales, with online shopping a common practice globally. While convenient, offenders have also embraced the opportunity to target potential victims and their shopping carts. Online shopping fraud occurs when offenders represent themselves as legitimate online sellers to gain sales from unsuspecting victims, both by impersonating genuine retailers and creating fictional retailers with non-existent products. The current article explores the victimisation and near misses of consumers to online shopping fraud. Based on survey responses of 1011 Australians, the article examines the online shopping activities of individuals as well as any victimisation or near miss experiences. The results indicate a high level of victimisation and near misses across this sample. It further examines a range of impacts experienced by these consumers and considers the implications of these results for the retail sector and prevention practices into the future.

Most research on illicit financial flows (IFFs) has focused on illicit outflows from low-income countries and the role of non-state actors in generating IFFs. Less attention has been paid to processes through which IFFs enter formal value chains – in effect being legalised before leaving the country – or the crucial role of state institutions as gatekeepers. We develop a novel explanatory approach to account for the enabling role of state institutions in the legalisation of IFFs. Building on political settlement theory, we explain the performance of institutions in regulating IFFs as a function to maintain political power. Taking the case of Bolivia, we examine how legalising illicit value flows works in practice and analyse the motives and underlying conditions that lead state institutions to permit the formal export of gold shipments that have been illicitly sourced or transferred. We find that the legalisation of IFFs accommodates the interests of powerful cooperatives dominating the gold-mining sector, which are critical to maintaining the political settlement on which the incumbent government’s power is based. By maintaining a status quo of non-enforcement, legal ambiguity, and informality, gold-mining cooperatives reap higher benefits from resource extraction at the expense of domestic revenue mobilisation.

Background:Cannabis use has increased in the United States as legalization has spread. While Δ-9 THC remains the most-used federally illegal substance, use of other psychoactive hemp-derived products (Δ-8 THC, Δ-10 THC, HHC, THC-O) has grown. The current study investigated patterns of cannabis use and perceptions of harm and benefit of cannabis across states with differing cannabis laws.

Method

Participants (N=639) were adults endorsing past-90-day cannabis use who lived in one of 15 states selected based on cannabis laws (recreational use, medical use, illegal). Participants completed self-report questionnaires endorsing types of cannabis used, methods of consuming and acquiring cannabis, and ranking of potential harm and benefit of consumption methods.

Results

The majority (N=573; 89.7% of participants) endorsed past-30-day use of Δ-9 THC, regardless of legal status. There was significantly greater use of alternate cannabis forms in states where Δ-9 THC remains illegal (past-90-day: χ2(2)=16.78, p<.001; past-30-day: χ2(2)=9.50, p=.009). Individuals from states with legal recreational cannabis most frequently purchased cannabis legally (52.0%), but high levels of non-legal purchase existed regardless of legal status (47.5%). Participants reported primarily consuming Δ-9 THC through smoking (86.1%), CBD through ingestion (50.5%), and alternative cannabis types through vaping (43.8-57.7%). Average harm rankings were lower for smoking if it was the primary method of consumption.

Conclusions

Individuals purchased and consumed cannabis regardless of legal status and legal status was not significantly associated with harm or benefit rating, controlling for demographic and use data. Individuals appear more likely to purchase through legal means, if available.

Background

In 2020, the U.S. state of Oregon passed Measure 110 (M110), which aimed to address substance use disorder as a public health issue and reduce disparities in the criminal legal system by decriminalizing personal drug possession and increasing services. The impact of partial drug decriminalization on individuals under community supervision—whose release conditions often prohibit drug use and who M110 excluded—is understudied.

Methods

We used targeted sampling to recruit and survey people who use drugs (PWUD; N=468) in eight Oregon counties in 2023. We compared PWUD under community supervision to those who were not to assess opioid-related overdose, naloxone access, and law enforcement engagement.

Results

Compared to PWUD who were not under community supervision, those under supervision had higher prevalence of past year opioid-related overdose. There were no differences by naloxone access. Eighty-two percent (82%) of PWUD on community supervision were stopped by law enforcement in the past year. PWUD on community supervision were more likely than those not on community supervision to report in the past year being searched by law enforcement at least once (adjusted prevalence differences [APD]=0.33; 95% CI: 0.23, 0.43), spent time in jail at least once (APD=0.33; 95% CI: 0.23, 0.43), and to have concerns about getting into trouble if they called 911 for a drug-related health problem (APD=0.12; 95% CI: 0.00, 0.18).

Conclusion

Under M110, Oregon PWUD experienced more police engagement and overdoses. Findings have implications for less police presence at overdose scenes, greater access to naloxone and support services, and protections under future decriminalization laws.

Objective:

This report identifies the specific drugs most frequently involved in drug overdose deaths in the United States from 2017 through 2023.

Methods:

Data from the 2017–2023 National Vital Statistics System mortality files were linked to literal text data from death certificates. Drug overdose deaths were identified using the International Classification of Diseases, 10th Revision underlying cause-of-death codes X40–X44, X60–X64, X85, and Y10–Y14. Specific drugs were identified by searching three literal text fields of the death certificate: the causes of death from Part I, significant conditions contributing to death from Part II, and the description of how the injury occurred. Contextual information was used to determine drug involvement in the death. Descriptive statistics were calculated for the most frequently mentioned drugs involved in drug overdose deaths. Deaths involving multiple drugs were counted in all relevant drug categories.

Results:

Among drug overdose deaths with mention of at least one specific drug, the most frequently mentioned drugs during 2017–2023 included: fentanyl, heroin, oxycodone, morphine, methadone, hydrocodone, alprazolam, diphenhydramine, cocaine, methamphetamine, amphetamine, gabapentin, and xylazine. Fentanyl ranked first across all years and was the most common concomitant drug found with other top drugs, ranging from 99.0% of xylazine-involved drug overdose deaths to 48.3% of oxycodone-involved drug overdose deaths. Cocaine and methamphetamine were also frequent concomitant drugs. Trends in age-adjusted rates across the 2017 to 2023 period varied by drug, but notably the rate for heroin-involved deaths sharply declined, while the rate for fentanyl-involved deaths increased and then stabilized between 2022 and 2023. In 2023, the most frequently mentioned drugs in unintentional drug overdose deaths were fentanyl, methamphetamine, and cocaine, while the most frequently mentioned drugs for suicide-related drug overdoses were diphenhydramine, oxycodone, and bupropion.

Conclusions:

This report identifies patterns in the specific drugs most frequently involved in drug overdose deaths from 2017 through 2023.National Vital Statistics Reports; CDC National Center for Health Statistics; 2026.

Highlights

•

The province of British Columbia (Canada) temporarily implemented a decriminalization initiative for personal drug possession/use (2023–2024) in contexts of a toxic drug death crisis.

1. •

   The decriminalization initiative was a priori promoted as a “tool to end the overdose crisis” and widely expected to reduce adverse health outcomes from toxic drug use.

2. •

   Emerging evaluation data indicate that the drug decriminalization initiative was not associated with population-level changes in drug use-related mortality (e.g., overdose deaths) or morbidity (e.g., hospitalizations).

3. •

   Drug use decriminalization remains an essential step to align prohibition-based drug policy frameworks with public health and human rights principles, but must be approached realistically and designed sensibly.

4. •

   To tangibly address toxic drug use-related harms, expanded measures are required that are effectively capable of preventing and reducing PWUDs’ exposure to and use of toxic drugs

Using household survey data on expenditures and incomes, we construct an objective measure of corruption in the public sector for a broad spectrum of countries. Specifically, we focus on the consumption-income gap for public sector workers relative to private sector workers to gauge the extent of hidden income (bribes) in the government. After validating our data and documenting properties of the consumption-income gap, we compare our measure with popular corruption perception indices. We find that i) the relationship between our measure and the alternatives is nonlinear; ii) available indices appear to be only weakly (and sometimes “wrongly”) correlated with the consumption income gap at high frequencies; iii) the available indices appear to have a low weight on the relative consumption-income gap in the public sector.

Brazil may join a small but growing number of countries that have already criminalised sexual corruption through specific legal provisions. This legislative effort shows how naming, strategic framing, and cross-sector collaboration can bring invisible gendered abuses into legislative concern. It offers critical lessons on the importance of political sponsorship, data collection, and media visibility for addressing complex, underreported crimes.
