British police are handing out “scratch and sniff” cannabis cards to inform the public of the smell of illegal weed farms. While some have been busy sniffing out their neighbors, dozens of UK celebrities have spoken out against the rampant “war on drugs.”

Police forces in England and Wales have been distributing A5-sized cards that emit the smell of growing cannabis when rubbed, urging people to report on similar suspicious smells in their neighborhood, UK media reports.

The educational campaign targets illegal growing hotspots and is said to be part of a publicity drive against drugs that was launched last spring.
