DENVER (KDVR) — A Colorado man has developed a  secret weapon to make sure the smell of marijuana doesn’t overpower local neighborhoods.

Certified odor observer Ben Siller’s job is to check out odor complaints the city of Denver receives.

“When medical marijuana first started that was some of the calls we were getting is these facilities were coming in to places and they never had that odor before,” Siller said.

He has a device that looks a little bit like a radar gun that can measure the exact ratio of clean, non-odorous air to the amount coming in from smells.
