Around 30,000 Dutch households have started receiving marijuana-scented scratchcards in an effort to uncover illegal cannabis plantations.

Authorities in Rotterdam and The Hague say they are distributing the cards to help people recognise what cannabis plants smell like.

They also include a telephone number to report suspected marijuana growing.

The electricity for heating and lighting the plants is often stolen and used unsafely.

Renee DeBruin is a spokeswoman for the Stedin, a gas and electricity supplier in the Netherlands, which serves two million households.
