While hippies and weed farmers are generally the non violent type, threaten their weed and you might have a laid back war on the smoke filled horizon. Pictured is the unmanned “Canna Chopper” used to hunt down weed fields and alert the proper authorities. Using odor and video detecting instruments, this weed chopper has just had its maiden voyage in the Netherlands where it spotted a flourishing marijuana farm. Seven growers were arrested and several kilos of outlawed weed were obtained. Boo! Let’s dope some hippies don’t get their dreads caught in the RPG trigger.
