“Thousand of houses in the UK are being sent marijuana-scented ‘scratch and sniff’ cards in a new bid to track down marijuana growers. The charity group Crimestoppers explained the cards were designed to educate residents about the smell of marijuana. They hope once people can recognize the smell of cannabis plants, they will be able to help law enforcement officials identify illegal growing operations. The green-and-black cards also provide other signs to look out for, including homes that have ‘visitors at unsociable hours’ or buildings that generate an excessive amount of heat. Homes with closed blinds should be under suspicion as well.”
