The unmanned mini-helicopter has been dubbed the "Canna Chopper," and has been put to use sniffing out illegal grow operations in the Netherlands. Apparently only 10% of Dutch-grown pot is legal. Who knew?

The Canna Chopper boasts odor and video sensors to find pot fields from the air, and on its first trip it rounded up seven outlaw farmers and several kilos of product, so looks like it's reasonably effective. Effective at being no fun. [Dutch Daily News via DVICE]
