Officers of the Financial Administration stopped a shipment in Sežana on 28 April 2025 that had travelled from Thailand to the Netherlands by ship and then by lorry to Slovenia.[1] The shipment was declared as tea — nine pallets, or 140 cartons — imported by a Danish company for a Dutch recipient.[1][2] After a suspicious sample emerged among tested packets, criminal investigators isolated the suspect packet and the National Forensic Laboratory confirmed it was cannabis.[1][2] A further check uncovered 925 kilograms of cannabis packed in smaller parcels of around 300 grams each.[1][2]

Police valued the 925 kilograms at about 2,312,500 euros on the black market.[1] The findings went to the Koper district prosecutor’s office, which opened pre-trial proceedings, while investigators worked to identify the origin of the drugs and their intended recipient.[1] The shipment’s unusual route — from the Netherlands to a Slovenian customs warehouse and back toward the Netherlands — raised questions about whether the declared recipient was the real one or had been abused for smuggling.[2] No one had been charged when the case was presented on 15 May 2025.[2]
