GRAND JUNCTION, Colo. - Authorities say the strange odor seeping into a western Colorado Census Bureau office came from more than 1,000 marijuana plants growing next door.
Grand Junction census workers say the smell was coming through the vents. Police got a search warrant Tuesday and found the plants next door in the same building.
Police say the building owner told them he was growing the plants for medical marijuana patients. Officers found state registration cards for medical marijuana users and are reviewing them.
No one's been arrested.
State law permits medical marijuana use but federal law does not. Last month, federal agents found 224 pot plants in the home of a suburban Denver man who said he was a medical marijuana provider. He's been charged with possession.
