Four people have been arrested after drugs warrants in Amble.
Officers targeted three addresses at Newburgh Street, Ivy Street and Bede Street, on Monday in an intelligence-led operation.
Quantities of cannabis and amphetamine were seized during the searches under the Misuse of Drugs Act.
Two teenagers, aged 17 and 16, were arrested on suspicion of possession of cannabis. Both have been bailed to attend a youth surgery.
A 42-year-old woman received a simple caution after being arrested on suspicion of possessing amphetamine with intent to supply.
A 29-year-old man arrested for possession of cannabis was also handed a simple caution.
The activity has been supported by Northumbria Police and Crime Commissioner Vera Baird who has reducing crime as one of the priorities in her Police and Crime Plan.
She said: “Illegal drug taking and supply can bring misery to neighbourhoods.
“Any initiative that ensures officers are targeting those involved in this activity with the aim of bringing an end to the harm they cause in Northumberland neighbourhoods and beyond is welcomed.
“Anyone who does suspect any illegal drug activity in their area should contact police so officers can take action.”
Amble Neighbourhood Sergeant, Neville Wharrier, said: “These warrants were all about disrupting those involved in illegal drugs. We have seized an amount of drugs and made arrests.
“We hope this sends out a clear message that we will always act on information received to make our community safe from the harm that drugs cause.
“We rely on help from the community to provide us with information about illegal drug use and supply. Anyone concerned about drugs where they live is asked to contact us.”
