North-east police officers reported 140 people to the procurator fiscal for drug offences in November.
Police have also said £9,000 of cash connected to the illegal supply of drugs was also recovered.
During the last two months’ officers have recovered more than a kilo of class A drugs.
Detective Chief Inspector Lorna Ferguson said: “The last few weeks has been a very busy period and has seen a huge amount of activity across the north-east from the police and our partners in targeting the illegal supply of drugs.
“During October and November, a multi-agency operation to tackle cuckooing drug dealing activity in Fraserburgh and Peterhead resulted in over 50 people being arrested after 34 drug warrants were executed with the operation focused on targeting the activities of predominantly England-based Organised Crime Groups (OCGs) who target members of the community by taking over their homes to sell drugs.
“As part of this operation, we identified a numbers of victims of cuckooing and they have been provided with support.
“Additionally, a number of those arrested have requested referral to substance misuse services and will be given the support they need to end the cycle of substance misuse.
“We will continue to focus our activity on working with our partners to address drug dealing and the associated issues that lead to drug abuse.
“Every piece of information we receive is useful and will be taken seriously.
“We are extremely grateful to the public for its support and continue to urge anyone with concerns or information about the supply of controlled drugs to contact us on 101 or Crimestoppers anonymously on 0800 555 111.”
