Cracking down on cannabis farms

— STRONG, sickly cannabis smell or overwhelming use of air fresheners.

— WINDOWS constantly covered and blacked-out.

— A STREAM of different late-night visitors.

— STRONG, constant light during the day and night.

— HIGH levels of heat coming through the walls of a neighbouring property.

— CONDENSATION in the windows.

— A CONSTANT low buzzing noise from extractor systems.

— CABLES, plastic sheeting and compost bags dumped by bins, in garden or the street.

Cannabis cultivation not only feeds a multimillion-pound black market in an increasingly potent and dangerous drug but it is a key driver in modern slavery.
