At the UN drug commission in Vienna on 9 March 2026, Colombian President Gustavo Petro delivered a speech that sharply criticised prohibition and exposed the social roots of coca cultivation in Colombia. But the broader lesson from his intervention, and from Europe’s own policy debate, is not that blanket legalization is the answer. It is that drug policy must move beyond false choices: states need stronger prevention and education, serious investment in vulnerable communities, intelligence-led international cooperation, and sustained action to dismantle the criminal and financial networks that profit from addiction and violence.
Speaking during the opening day of the 69th session of the UN Commission on Narcotic Drugs in Vienna, Petro gave one of the most politically charged interventions of the day. His speech, published by the Colombian presidency, challenged decades of orthodoxy on the “war on drugs” while forcing delegates to confront a question that has haunted Latin America for years: what happens when prohibition punishes the poor, enriches organised crime and still fails to eliminate demand?
Petro began with cannabis, using it as an example of what he sees as a historical and moral contradiction. Referring to the contrast between the human cost of prohibition in producing countries and the legalisation or normalisation of cannabis in parts of the global north, he asked why so many Colombians had died around a substance that is now legally sold in major American cities. His answer was blunt: “Prohibition implies the creation of the mafia. And the creation of the mafia implies death and violence.”
That line will be widely quoted, and with reason. It captures the core of Petro’s critique. But it should not be read too simply. His speech did not amount to a complete legalization blueprint for every substance, nor did it offer a permissive approach to drugs in general. What it did was reject the idea that criminal bans alone can solve a phenomenon driven by social despair, global demand, organised crime and massive financial flows.
More than a choice between prohibition and legalization
That distinction matters. It is possible to accept Petro’s criticism of prohibition without concluding that blanket legalization is the obvious alternative. In fact, the stronger conclusion from Vienna is that neither formula, on its own, is sufficient.
Prohibition by itself has often fuelled black markets, corruption and violence, especially in fragile rural regions where poor farmers bear the costs and criminal organisations capture the profits. Yet legalization, by itself, would not automatically dismantle trafficking routes, criminal logistics, money laundering systems or the multinational distribution chains that today behave less like old cartels and more like transnational corporate crime structures. A legal market for one substance does not neutralise the networks that traffic others, nor does it solve addiction, predatory supply chains, synthetic drug threats or the public-health emergencies linked to abuse.
That is why the most credible reading of Petro’s intervention is not “legalize everything” but “stop pretending that repression alone works.” From there, the real policy question becomes more serious: how do states reduce demand, protect the vulnerable and destroy the criminal infrastructure of supply?
Petro’s social diagnosis of the drug economy
One of the most striking parts of Petro’s speech was his attempt to describe different drugs not only chemically, but sociologically. Cannabis, he argued, emerged in modern history as a substance associated with youth protest. Cocaine, by contrast, belonged to a different social order. “Cocaine is the drug of capital, no longer of protest,” he said. “It is necessary to increase the working day.” In another pointed phrase, he described it as “the drug of Wall Street.”
Whether one accepts that framing in full or not, the political purpose was clear. Petro was trying to redirect attention from the fields of Colombia to the societies that consume, finance and normalise the demand. In that sense, his speech was also a challenge to Europe. As the European Union Drugs Agency has warned, cocaine remains the second most commonly used illicit drug in Europe after cannabis, and its availability across the continent continues to rise.
Petro reserved even harsher language for fentanyl, which he called “a drug of death.” Here too, his point was not to relativise cocaine or cannabis, but to argue that the spread of different substances reflects deeper crises inside societies: loneliness, despair, pressure, competition and social fragmentation. It was a controversial analysis, but one that underscored a wider truth often missing from diplomatic statements: drug markets are not only a law-enforcement problem. They are also a mirror of social breakdown.
Colombia’s coca fields and the question of inequality
Where Petro was at his strongest was in linking coca cultivation to inequality and land exclusion. He argued that coca leaf in Colombia is cultivated not because peasant communities are naturally tied to the cocaine trade, but because generations of poor rural families were displaced from fertile land by violence and left with few viable alternatives. In one of the clearest lines of his address, he said coca cultivation persists because Colombia has not been able “to democratise land tenure and give poor peasants fertile land to produce food.”
That argument has major implications for policy. If coca cultivation is rooted in exclusion, then eradication without social reform becomes a revolving door. One plantation is destroyed, another appears. One family loses a crop, another enters the trade. The cycle repeats because the economic logic remains intact.
That is why Petro defended voluntary crop substitution so strongly. He said his government has already reached 42,000 hectares in voluntary substitution efforts and argued that this method is more durable than forced eradication because communities themselves participate in uprooting the crop. “Voluntary substitution means that the heart, the spirit, the desire of the peasant excluded for generations is on the side of this government,” he said, describing farmers physically pulling coca plants “out by the root.”
On this point, the speech deserves serious attention. States will not defeat illicit production in poor rural areas unless they provide real alternatives: roads, legal markets, schools, public services, land security, credit and the possibility that a child can build a future outside the narco-economy.
Prevention is not a slogan but a state investment
Still, substitution at the source is only one side of the equation. If demand remains strong, criminal markets adapt. That is where prevention becomes central. Petro’s speech pointed forcefully toward the failures of the old model, but Vienna also highlighted something else: prevention and education cannot remain secondary add-ons in drug policy. They have to become core state investments.
The European Union’s statement to the same session made that case in more institutional language. The EU called for an “evidence-based, integrated, balanced, multidisciplinary and human rights-centred approach” and explicitly prioritised “evidence-based prevention, early intervention, treatment, care, recovery, social reintegration” alongside stronger security action. That balance is important. Prevention is not moralising rhetoric. It is a practical strategy to reduce the number of future consumers and shrink the business base of organised crime.
For that reason, education matters far beyond school campaigns. It includes early prevention in families and communities, credible information for young people, support services in vulnerable neighbourhoods, mental-health resilience, and long-term public investment in places where criminal recruitment is easiest. Prevention lowers demand over time. Lower demand weakens the market. And a weaker market gives criminal organisations less room to grow.
Destroying the networks, not only seizing the product
Petro’s strongest operational message was not about legalization at all. It was about networks. He argued that modern drug mafias are no longer isolated cartels of the past but multinational structures involved not only in narcotics, but also in arms trafficking, human exploitation and wider forms of organised crime. In his words, today’s criminal structures are “multinational” and deeply embedded in global routes of money and luxury.
That led him to one of the speech’s most important conclusions: “The kingpins of kingpins are untouched.” He argued that they do not live in the producer regions of the south and that reaching them requires political will to follow the money into the international financial system and the world’s wealthy urban centres.
Here Petro’s argument intersects with a position that many European governments would recognise. The EU told the Vienna session that its strategy includes stronger information exchange, better forensic and investigative capacity, deeper operational cooperation with partner countries, disruption of trafficking routes and illicit financial flows, and action against criminal infiltration of ports and logistical hubs. That is the hard centre of any serious anti-cartel policy.
Put plainly, the objective cannot only be to destroy crops or intercept shipments. It must be to dismantle distribution networks, freeze assets, expose money laundering, seize logistics chains, prosecute high-level organisers and connect intelligence across borders quickly enough to keep pace with organised crime. The state must be smarter, faster and more coordinated than the networks it is trying to defeat.
The lesson from Vienna
Petro came to Vienna to say that the old prohibitive model has failed too many communities in Latin America. On that point, his speech was powerful and, in important respects, persuasive. But the most useful conclusion for Europe and the wider international debate is not that legalization should simply replace prohibition.
The real lesson is harder and more demanding. Drug policy must leave behind simplistic binaries. States should not rely on prohibition as a final answer when it has repeatedly generated black markets and violence. But they should also not imagine that legalization would dissolve the criminal architectures that now span continents, as they will even increase them.
A serious strategy has to work at every level at once: prevention and education to reduce demand; public-health support for those at risk; rural development and crop substitution to reduce production; intelligence-sharing and law-enforcement cooperation to dismantle cartels and trafficking routes; and financial investigations strong enough to reach the upper tiers of the criminal economy. That is where the real struggle lies.
As The European Times has already reported from the opening of CND69 in Vienna, this week’s debate is about more than drugs alone. It is about what kind of states still have the capacity to protect life, confront organised crime and invest in prevention before violence becomes business. Petro’s speech raised that challenge sharply. The answer now depends on whether governments are willing to move from slogans to strategy and prevention.
