Six people were arrested when police carried out two separate warrants on the same property in Buxton.
The first warrant was executed at the property, in Fairfield Road, at 6.30am on Friday, May 3.
Five people were arrested on suspicion of possessing controlled substances with intent to supply.
Officers also seized a number of suspected drugs and paraphernalia from the scene.
The five who were arrested – a 28–year–old woman and four men aged 21, 31, 35 and 40, all from the Buxton area – have been bailed pending further enquiries.
At 8am on Friday, May 10, a second warrant was executed at the premises.
As a result, a 42–year–old man from the Buxton area was arrested on suspicion of theft from a motor vehicle.
Officers found items in the property that were suspected to have been stolen from a car that had been parked in North Road, Buxton, the previous day.
The man has subsequently been bailed pending further enquiries.
Inspector Colin Ingley, who is in charge of policing in Buxton, said: “We have carried out several warrants in the area recently as part of our efforts to keep the community of Buxton safe.
“We rely on information from members of the public so if you want to speak to an officer, report suspicious activity or crime, please call us.”
