How drug trafficking started and expanded in Mexico.
The rise, evolution, and impact of major Mexican drug cartels.

1. Origin and Meaning of the Word “Cartel”

Meaning and Etymology

The word “cartel” comes from the Italian “cartello,” meaning “placard,” and the Latin “charta,” meaning “paper or document.” Historically, the term described formal agreements among competing businesses, mainly to control prices or manage production levels.

The first known use in English dates back to late 19th-century Europe, referring specifically to economic alliances. These early cartels helped companies stabilize markets and maximize profits by reducing competition.

Transition from Commerce to Criminality

In the early 20th century, “cartel” still meant business monopolies or alliances. But by the mid-to-late 20th century, the meaning shifted dramatically. The term became associated with organized crime groups engaged primarily in drug trafficking.

This shift started prominently with Colombian cocaine cartels in the 1970s and 1980s. The infamous Medellín and Cali cartels introduced violence, territorial control, and political influence to drug trafficking. Mexican criminal groups quickly followed this model, forming structured criminal enterprises known today as Mexican drug cartels.

Today, the term “cartel” rarely refers to legitimate business agreements. Instead, it is almost exclusively linked to criminal organizations known for drug smuggling, violence, corruption, and widespread economic and social impact.

2. Early History of Drug Trafficking in Mexico (Early 20th Century–1960s)

Opium and Marijuana Smuggling

The early history of drug trafficking in Mexico began during the Prohibition era (1920–1933) in the United States. As alcohol became illegal in the U.S., demand for illicit substances like alcohol, opium, and marijuana increased significantly.

During this period, Mexico became a primary supplier, fueling smuggling operations across the border. Initially, these trafficking groups were small-scale, family-run businesses rather than organized cartels. They operated independently, moving limited quantities of substances across the border through informal routes.

This era laid important groundwork for future trafficking operations by establishing the initial smuggling routes and basic distribution networks into the United States.

Foundations for Organized Crime

After World War II, drug trafficking from Mexico to the United States expanded rapidly. American demand for narcotics—particularly marijuana and heroin—increased dramatically. As a result, Mexican smugglers saw opportunities for greater profits and influence.

New criminal groups began forming around key geographic areas known today as cartel strongholds, such as Sinaloa, Chihuahua, and Durango. These regions offered ideal conditions for drug cultivation and provided safe passage into the U.S.

Another crucial factor during this period was corruption. Early drug traffickers started establishing informal arrangements with local authorities, securing protection and influence. This corruption laid the groundwork for the powerful, politically influential drug cartels seen in later decades.

3. The Rise of Modern Mexican Drug Cartels (1970s–1980s)

Guadalajara Cartel—The First Major Cartel

The modern era of Mexican drug cartels began with the emergence of the Guadalajara Cartel in the late 1970s. This cartel represented Mexico’s first highly structured drug-trafficking organization, marking a major shift in how criminal groups operated in the country.

The Guadalajara Cartel was led by influential figures such as Miguel Ángel Félix Gallardo, Rafael Caro Quintero, and Ernesto Fonseca Carrillo. Under their leadership, the cartel grew rapidly by connecting with Colombian cocaine producers. This partnership transformed Mexico into a key transit route for cocaine trafficking into the United States.

According to Interpol reports, the Guadalajara Cartel significantly expanded drug production, transportation routes, and distribution networks, setting a blueprint for modern cartel operations.

Impact of Guadalajara Cartel

The cartel quickly became a dominant force, controlling large-scale marijuana plantations and trafficking cocaine. By establishing organized trafficking routes through Tijuana, Juárez, and the Gulf region, the Guadalajara Cartel laid the groundwork for future cartels to follow (OECD, 2016).

The cartel’s growing power and corruption posed significant challenges for law enforcement, both domestically and internationally. One of the most notorious incidents illustrating their reach was the kidnapping, torture, and murder of U.S. Drug Enforcement Administration (DEA) agent Enrique “Kiki” Camarena in 1985. Camarena’s death sparked a major diplomatic and law enforcement response from the U.S. government, leading to intensified efforts to dismantle the cartel.

This event highlighted the extreme violence and boldness that defined Mexican cartels in the decades to follow. It also demonstrated the need for international cooperation in tackling drug trafficking (FATF, 2019).

4. Fragmentation and Growth of Major Cartels (1990s–2000s)

Breakdown of the Guadalajara Cartel

By the early 1990s, Mexican drug trafficking underwent major changes following the arrest of Guadalajara Cartel leaders, including Miguel Ángel Félix Gallardo in 1989. This event caused the cartel to split into smaller, independent groups, each seeking control over drug routes and territories.

From this fragmentation, several powerful cartels emerged, notably the Sinaloa Cartel, led by Joaquín “El Chapo” Guzmán, the Tijuana Cartel, also known as the Arellano Félix Organization, the Juárez Cartel, and the Gulf Cartel in northeastern Mexico.

According to academic studies, the breakdown of the Guadalajara Cartel set the stage for intensified competition and violence among emerging cartels, each striving for dominance over lucrative drug trafficking corridors (OECD, 2019).

Cartel Wars and Violence

Throughout the late 1990s and early 2000s, Mexico saw a significant escalation in violence due to cartel rivalries. Battles over strategic trafficking routes, especially along the U.S.-Mexico border, led to unprecedented levels of brutality and civilian casualties.

During this period, drug-related violence surged dramatically. According to Interpol, organized crime homicides in Mexico increased by over 60% between 2000 and 2009, reflecting the growing aggression and militarization of cartel operations.

This increase in violence coincided with deepening corruption. Drug cartels expanded their influence, infiltrating law enforcement, military ranks, and political institutions. This corruption severely weakened government efforts to combat drug trafficking and maintain public security (FATF, 2018).

5. Intensified Drug Wars and Government Response (2006–Present)

Militarized Drug War

In 2006, Mexican President Felipe Calderón declared an aggressive military-led “war on drugs,” significantly altering the government’s approach to cartels. Deploying over 45,000 troops nationwide, this strategy aimed at dismantling major criminal organizations and restoring public security.

However, rather than reducing violence, the policy dramatically intensified it. Between 2006 and 2022, drug-related violence resulted in more than 360,000 deaths and countless disappearances, according to data from Mexico’s National Institute of Statistics and Geography (INEGI).

This period saw the emergence of extremely violent groups, notably Los Zetas and the Jalisco New Generation Cartel (CJNG). Los Zetas, originally ex-military members, introduced unprecedented brutality, while CJNG quickly became one of Mexico’s largest and most aggressive cartels.

Effects of International Cooperation

Recognizing the severity of cartel violence, Mexico and the United States launched the Mérida Initiative in 2008. This partnership involved the U.S. providing financial support, training, and intelligence-sharing to strengthen Mexico’s security and judicial institutions (OECD, 2021).

The initiative has led to significant successes, such as the capture and extradition of high-profile cartel leaders like Joaquín “El Chapo” Guzmán in 2016. Interpol highlighted improved cooperation between Mexican and international law enforcement agencies as a critical outcome.

Despite these successes, the strategy also faced considerable criticism. According to reports by the Financial Action Task Force (FATF, 2020), violence persisted, cartels fragmented further, and corruption remained pervasive, complicating efforts to achieve lasting peace and security.

Thus, while international cooperation helped in some ways, it did not fully resolve Mexico’s cartel crisis, illustrating the complexity and deep-rooted nature of organized crime.

6. Evolution of Cartel Operations and Tactics

Adapting Trafficking Methods

Mexican drug cartels have consistently adapted their trafficking methods to avoid detection by authorities. Initially relying on basic smuggling methods such as hidden compartments in vehicles, they quickly evolved into more advanced techniques.

Today, cartels employ sophisticated methods such as tunnels beneath the U.S.-Mexico border, semi-submersible vessels, small aircraft, drones, and encrypted communication networks. According to Interpol (2022), the use of drones has increased dramatically, allowing cartels to deliver small quantities of high-value drugs, like fentanyl, across borders without detection.

The Organization for Economic Cooperation and Development (OECD, 2021) highlights how these technological adaptations have made cartel operations increasingly difficult to intercept, requiring advanced surveillance and international collaboration.

Shift to Synthetic Drugs

Over the past decade, cartels shifted significantly towards synthetic drug production, particularly methamphetamine and fentanyl. Unlike traditional plant-based drugs such as marijuana, cocaine, and heroin, synthetic drugs require fewer resources, are easier to conceal, and generate higher profits.

Data from the Financial Action Task Force (FATF, 2022) indicates fentanyl trafficking has surged, causing a public health crisis in the United States and Canada. Mexican cartels now dominate fentanyl supply chains, importing precursor chemicals primarily from Asia, then synthesizing and trafficking the finished product.

This shift poses significant challenges for law enforcement due to the complexity of chemical supply chains and the ease of manufacturing synthetic drugs. It demands greater international cooperation, chemical tracking, and enhanced regulatory oversight to mitigate the growing threat.

7. Economic and Social Impact of Mexican Drug Cartels

Violence and Human Cost

The most significant impact of Mexican drug cartels is the immense human suffering caused by widespread violence. Since the Mexican government launched its intensified war on drugs in 2006, cartel-related homicides have exceeded 360,000 deaths, according to Mexico’s National Institute of Statistics and Geography (INEGI, 2024).

Beyond homicides, cartel violence has displaced hundreds of thousands of people. Families fleeing cartel-controlled regions face poverty, insecurity, and limited access to basic services such as healthcare and education. According to studies by the OECD (2021), this mass displacement severely disrupts local economies and destabilizes communities.

Corruption and Governance Issues

Drug cartels significantly undermine Mexico’s governance through widespread corruption. According to a FATF report (2022), cartels routinely bribe and intimidate public officials, law enforcement, and even military personnel to ensure operational security. This corruption enables cartels to evade law enforcement and prosecution effectively.

Interpol (2023) emphasizes that cartel corruption weakens public trust in government institutions, creating a crisis of legitimacy. As a result, effective governance becomes increasingly difficult, as citizens lose confidence in authorities’ ability to protect them or deliver justice.

The resulting instability has significant implications for Mexico’s economic growth, discouraging investment, hindering economic development, and contributing to ongoing social inequalities.

8. Major Cartel Figures in History

Notable Leaders and Their Influence

Joaquín “El Chapo” Guzmán – Sinaloa Cartel

Joaquín “El Chapo” Guzmán became one of the most infamous cartel leaders globally. Leading the powerful Sinaloa Cartel, Guzmán significantly expanded drug trafficking operations, notably cocaine, heroin, and synthetic drugs. Known for daring prison escapes and ruthless violence, he symbolized cartel influence and corruption. His eventual extradition and sentencing to life imprisonment in the United States marked a landmark case against cartel leadership.

Osiel Cárdenas Guillén – Gulf Cartel

Osiel Cárdenas Guillén led the notorious Gulf Cartel, dramatically altering its structure and operational tactics. Guillén notably founded the paramilitary group Los Zetas, initially recruiting ex-special forces to act as cartel enforcers. His aggressive strategies sparked intense violence along the U.S.-Mexico border. Arrested in 2003 and extradited to the U.S. in 2007, Guillén’s imprisonment fragmented the cartel, causing violence to escalate further as rival factions fought for dominance.

Nemesio “El Mencho” Oseguera Cervantes – CJNG

Nemesio Oseguera Cervantes, known as “El Mencho,” leads the rapidly expanding and notoriously violent Jalisco New Generation Cartel (CJNG). Known for using extreme violence to secure territories, El Mencho turned CJNG into one of Mexico’s largest criminal threats today. According to Interpol (2023), the CJNG’s growth represents one of the most significant shifts in cartel dynamics over the past decade, expanding internationally and increasing synthetic drug production, particularly fentanyl and methamphetamine.

9. International Influence of Mexican Cartels

Global Networks and Partnerships

Mexican drug cartels have expanded well beyond national borders, establishing influential networks across the globe. According to Interpol (2023), Mexican cartels actively operate not only throughout North America but have also made significant inroads into Europe, Asia, and Australia.

The cartels primarily use these international networks to facilitate drug trafficking, money laundering, and weapons smuggling. Their extensive reach allows them to control distribution channels in key markets, making them influential players in global illicit drug economies.

Interactions with International Crime Syndicates

Mexican cartels frequently collaborate with other major international criminal groups. They maintain strong operational relationships with Colombian cocaine producers, exchanging cocaine shipments for cash, weapons, or precursor chemicals used in synthetic drug manufacturing.

In Europe, Mexican cartels partner with powerful criminal organizations such as the Italian Mafia, including the ‘Ndrangheta, to distribute drugs like cocaine and methamphetamine. According to Europol’s Serious and Organised Crime Threat Assessment (SOCTA, 2021), these partnerships have significantly increased the availability and use of illicit drugs across Europe.

Asian organized crime syndicates also cooperate with Mexican cartels, especially in supplying precursor chemicals crucial for manufacturing synthetic opioids like fentanyl. The FATF (2022) highlights the complexity of these global chemical supply chains, which makes controlling drug flows particularly challenging.

Through these strategic alliances, Mexican cartels continue to expand their global influence, representing an ongoing challenge for international law enforcement.

10. Future Trends and Challenges

Emerging Trends in Cartel Activities

Mexican drug cartels continually evolve, leveraging technology to strengthen their operations and evade law enforcement. One growing trend is their increased use of cryptocurrencies, encrypted communication apps, and advanced cybercrime techniques for money laundering and secure communication. According to the FATF (2022), cartels now frequently use Bitcoin and other virtual currencies to disguise financial transactions and move funds globally.

Another notable trend is the rising dominance of the Jalisco New Generation Cartel (CJNG), rapidly expanding its territorial influence. As reported by Interpol (2023), CJNG’s aggressive tactics and global networks position them as a significant future threat.

Furthermore, synthetic drugs like fentanyl continue to present enormous challenges. The production and trafficking of synthetic opioids have surged, leading to an escalating public health crisis, particularly in North America. The U.S. Drug Enforcement Administration (DEA) emphasizes the urgent need to address these powerful synthetic substances through international cooperation and tighter control over precursor chemicals.

Recommended Strategies for Combating Cartels

Effectively combating Mexican drug cartels requires comprehensive strategies rather than isolated enforcement measures. Key recommendations include:

Economic Development: Providing alternative employment opportunities in cartel-dominated regions to reduce local dependency on drug economies.
Anti-Corruption Initiatives: Strengthening transparency, judicial integrity, and law enforcement accountability to reduce cartel influence on public institutions, as recommended by the OECD (2021).
International Cooperation: Enhancing cross-border collaboration in intelligence-sharing, financial tracking, and joint law enforcement operations.
Demand Reduction: Addressing drug demand in consumer countries through education, prevention, and treatment programs, reducing the profitability and power of cartels.

Implementing these combined strategies could significantly weaken cartel operations and mitigate their long-term impact.
