Norwegian police uncovered a large cannabis plantation on a remote farm in Indre Fosen, Trøndelag, after officers noticed the smell of cannabis during surveillance in autumn 2024.[1] Two Poles had bought the farm in the summer of 2020 without arousing suspicion, and prosecutors say the operation had run since at least 2021.[1] The search found 2,000 plants and about 130 kilograms of processed material.[1]

Eight Polish men were detained, most of them held in custody since November 2024.[1] Six were charged with drug production as part of an organised criminal group, each with a defined role from buying the farm to building and running the plantation.[1] One of the men is also accused of smuggling more than three million cigarettes and 20,000 litres of alcohol into Norway.[1] Two men deny wrongdoing and one admits partial guilt.[1]

One participant was sentenced in October 2025 to one year and six months in prison, and the remaining case was due before the District Court in Trøndelag in December.[1]
