Police Scotland carried out 40 drug raids, seizing more than £7,000 in cash last month.
Officers in the north-east have also recovered 5.4kg of cannabis, 800 grams of crack cocaine and more than 400 grams of heroin throughout May.
A total of 100 people were also reported to the Procurator Fiscal for drug-related offences.
DCI Lorna Ferguson urged people to come forward with information about drugs.
She said: “It’s the public who can help us break the chain between drug use and crime so if you’re concerned about dealing in your area, no matter how insignificant you think your information is, we want to know.”
