Maranhão security forces eradicated a cannabis plantation of about 22,200 plants in the rural area of Santa Helena, in the Baixada Maranhense, on Saturday 23 May 2026.[1] Officers found four areas used to grow the drug and incinerated the whole plantation on the spot.[1]

According to the police, destroying the plants prevented about 3.5 tonnes of the drug from reaching the illegal market.[1]

Part of the seized items was taken to the civilian police station, which will continue the investigation.[1] The state security secretariat said the operation was carried out by Air Tactical Centre (CTA) teams using the Águia 07 helicopter and operational vehicles, with military police from the 2nd Company, the Special Operations Group and the intelligence sector of the 10th Military Police Battalion of Santa Helena.[2]

The security forces estimated the destruction removed about 3.5 tonnes of the drug from the illegal market and cost the trafficking groups more than R$7 million.[2] The action was part of Operação Brasil Contra o Crime Organizado, in its Bioma/Amazônia axis, a national effort against drug trafficking, criminal factions and environmental crime in the Amazon region.[1]
