Police have seized cocaine and heroin with an estimated street value of £500,000.
Officers with a warrant raided a property in East Main Avenue in the Mastrick area of Aberdeen at 12.10pm on Saturday.
Two men, aged 27 and 31, and a 29-year-old woman were arrested and charged and are due to appear at Aberdeen Sheriff Court later.
Detective Inspector Robin Sim said: “Drug misuse brings nothing but misery to our communities and I want to reassure the people of Aberdeen that we will continue to use every tool and tactic at our disposal to remove these illegal substances from our streets.
“Our work often relies on the support of the public, so, if you have any information or concerns about drug misuse, do not hesitate to contact Police Scotland on 101 or report this anonymously via Crimestoppers on 0800 555 111.”
