Special units of the Maranhão public security forces destroyed more than 36,000 cannabis plants in the municipality of Centro do Guilherme, about 400 km from the state capital São Luís, on Wednesday 19 March 2025.[1] The teams located and destroyed two large cannabis plantations in the municipality and burned the seedlings on the spot.[2] Jovem Pan São Luís reported that the two plantations’ seedlings were incinerated after the cultivation areas were identified.[3]

The Maranhão Military Police said the 19 March action was the first day of an intensified drive against crime in municipalities of the Gurupi and Turi regions, which have illegal cannabis cultivation.[1] The destroyed plants were estimated by the authorities to be enough to produce three tonnes of cannabis.[1] On Thursday 20 March the teams were working in the neighbouring municipality of Centro Novo, a second stage of the same drive.[2] The Maranhão public security secretariat said further incursions would follow in the coming days to identify and break up criminal schemes.[2]

Lieutenant-colonel Onildo, commander of Special Missions of the Maranhão Military Police, said the eradication and incineration of the plants stopped the drugs reaching the streets and struck a blow against drug trafficking.[1] Besides the Air Tactical Centre (CTA), a military police aviation unit, the action involved the Maranhão Military Police’s special operations battalion (Bope), its riot battalion (BPChoque), the Rotam mobile tactical patrol unit and the canine unit.[1] The deployment falls under Operation Renoe (Rede Nacional de Operações Ostensivas Especializadas), an initiative of the National Public Security Secretariat (Senasp) of the Ministry of Justice and Public Security.[1]
