Key Takeaways Significant gross income from illicit drug trafficking Between 2019 and 2022, the Balkan route – a major corridor for trafficking opiates and, more recently, methamphetamine – generated an estimated total annual illicit gross income ranging from US$13.9 to US$21.4 billion. Opiates accounted for about 90 per cent of this total, with methamphetamine representing a smaller but growing share. The aggregated value of these trafficking flows surpasses the gross domestic product (GDP) of several countries along the route, highlighting the significant economic impact of these illegal activities. The data and analysis do not cover the period following the drug ban in Afghanistan that was imposed in 2022 by the Taliban and its impact on drug consumption and trafficking patterns. Geographic distribution of trafficking routes The Balkan route remains a critical pathway for drug trafficking, stretching from Afghanistan through Iran (Islamic Republic of) and Türkiye, and splitting into three main branches, all leading into Europe. Alongside the opiate flow, methamphetamine trafficking is expanding, with manufacturing hotspots identified in Afghanistan, Eastern Europe (Bulgaria, Czechia and Slovakia), Southern Europe (Greece) and Western Europe (Germany and the Kingdom of the Netherlands). Opiates and methamphetamine trafficking is concentrated in key hubs Given their location at the start of the Balkan route, Iran (Islamic Republic of) and Türkiye are the main hotspots for trafficking both drugs. Trafficking through Iran (Islamic Republic of) plays a pivotal role in the opiate trade, accounting for over one-third of total gross income along the Balkan route related to opiates. Other key trafficking hotspots can be found in Belgium and the Netherlands (Kingdom of the). These countries are not only key stops for traffickers but also act as hotspots for distributing opiates and methamphetamine in smaller quantities. Illicit actors in some countries like the Netherlands (Kingdom of the) also contribute to methamphetamine manufacture the impact of proximity and trafficker adaptability on interception rates Interception rates of illegally traded opiates and methamphetamine along the Balkan route are highest in the proximity of production sources. Iran (Islamic Republic of) and Türkiye intercept the highest percentage of all opiates that cross their territories at 28.2 and 29.3 percent respectively. Traffickers' adaptability − through tactics such as breaking shipments into smaller quantities, altering routes and employing advanced concealment methods − continue to pose significant challenges to law enforcement, particularly further along the supply chain. High profit margins in the drug trade Trafficking of opiates and methamphetamine can yield substantial profits, with an estimated combined annual illicit net income ranging from US$10.9 to US$16.9 billion. These profits represent more than 70 per cent of the total illicit gross income acquired through the trafficking of these two substances after deducting intermediate expenditures, production and purchasing costs.The largest shares of illicit net income are generated at the retail level, where price markups are highest. However, individuals higher up in the supply chain may earn more per person, as fewer people share the profits at the international and wholesale levels. Illicit financial flows (IFFs) related to the management of drug trafficking profits are in the order of billions. IFFs are cross border flows of financial or nonfinancial assets that are illicit in origin, transfer or use. These flows represent the hidden movement of wealth that undermines economic stability and evades lawful oversight. Looking at IFFs generated through the trafficking of opiates and methamphetamine, it is estimated that between a quarter and half of the US$13.7 billion in illicit net income generated from drug trafficking along the Balkan route is illegally moved across borders, generating potential IFFs related to the management of drug trafficking profits of US$3.4 billion to US$6.9 billion annually. Link between money laundering and IFFs There is some evidence that income from drug trafficking is laundered both domestically and abroad through investments in real estate, luxury vehicles and other assets. Shell companies and informal systems like Hawala are frequently used to transfer and launder money, complicating efforts to trace the illicit proceeds. Key trafficking transit points not only facilitate drug movement but also serve as hubs for laundering and redistributing illicit financial resources. Contrary to common assumptions, traditional tax havens may play a minimal role in laundering drug trafficking proceeds. Instead, the limited available data suggests that countries like Luxembourg, the Netherlands (Kingdom of the) and Spain are potential hubs for drug-related IFFs generated along the Balkan route, alongside the United Arab Emirates.
