To all drug sniffer hideouts comes another sniffer, this one is a UAV that too sniffs cannabis. Drug trafficking is one of the biggest menaces in society, and the military and authorities have had enough searching out cannabis fields and traffickers. Now, a Dutch made Mini helicopter will do the job. The Canna chopper by the Dutch police is made to track down all illegal weed farms. The mini-heli can stay in the air for about 8 hours, and with its embedded camera and sensors sniffs for odor to detect cannabis-growing areas and help combat illegal cannabis crop growers. The effectiveness of the unmanned vehicle can be gathered from the fact that in its first flight the chopper managed to detect a field.
