More than 30,000 Dutch households will be granted a marijuana-scented scratch card, which in turn will aid in detecting illegal urban cannabis plantations.

The card comes with a number to call to report suspected marijuana-plantation. Dutch authorities seemingly have overlooked on the matter when citizens seem to be growing up to five marijuana plants for personal use.

The spokesperson for government-appointed working group to combat cannabis cultivation in the Netherlands, Arnie Loos explained: "Citizens must be alerted to the dangers they face as a result of these plantations, and if they become aware of any suspect situations they must report them."

The green scratch card, measures 20cm by 10cm (8in by 4in) reads "Assist in combating cannabis plantations”.

When scratched the card oozes its scent as well as a police number people when one suspects that a neighbor has grown marijuana on a large scale.

Dutch officials believe that these plantations come in form of danger, which might lead to fire accidents due to the cables and lamps required to provide a cultivation temperature of 27C.
