Police are urging people in Cromford to report drugs offences following a week-long crackdown.
Officers carried out extra patrols in the village last week to help gather information on the problem.
PCSO Karl Millward said: “Our focus on drugs issues doesn’t end with this operation and we need people to come forward and help us tackle it further.
“If you suspect someone of being involved in activity surrounding drugs, whether it’s dealing, production or abuse, please call. It could make a huge difference to your community.” Phone PCSO Millward on 101.
