On Tuesday, 70 officers visited 695 addresses and made seven arrests after seizing more than £18,000 worth of drugs and £2,000 of cash.
Chief Constable Vanessa Jardine said: "Today shows that we will not tolerate criminal behaviour in our communities. We are here today to say there is no place for it and we will come and take action.
"We want the community to know that we do listen to them and that we will act on the information they tell us.
"There is no place in our communities here in the North East for those who want to partake in criminal activity."
Anyone who is aware of any form of criminal activity is encouraged to contact police and report it.
