Four people have been arrested and £170,000 worth of cannabis and cocaine seized in separate police raids.
A search of a house in Underwood Road in Newmains, North Lanarkshire, found cocaine with an estimated street value of £80,000 and cannabis worth about £75,000.
Two men, aged 30 and 34, and a 30-year-old woman were arrested in connection with the find.
They remain in custody and are due to appear at Hamilton Sherriff Court on Friday.
Earlier in the day, cannabis worth £15,000 was discovered in a house in Glendale Avenue, Airdrie, also North Lanarkshire.
A four-figure sum of cash was also found in the raid at about 12.30pm and a 42-year-old man was arrested, Strathclyde Police said.
