Marijuana-scented scratch cards are to be posted to Nottinghamshire households in a bid to detect illegal cannabis farms.

Crimestoppers said the cards were being posted to 13 areas in England, and would help people to recognise the smell of cannabis in order to report it.

Nottinghamshire's Police and Crime Commissioner Paddy Tipping said cannabis farms were increasing in the county and he needed the public's help, as East Midlands Today's Paul Bradshaw reports.
