Santa Barbara Coalition for Responsible Cannabis coalition has spent over a million dollars fighting weed farms in the county. Two years ago, after much legal wrangling, they signed a peace treaty with a leading growers’ organization in the Carpinteria Valley. But they say they haven’t followed the deal which included installing the latest tech to “clean the smell”.

Residents want them to adopt state-of-the-art clean-air technology in their open-vented greenhouses. Carbon filters called “scrubbers” have been shown to be effective in preventing the smell of cannabis from wafting out of the roof vents and into neighborhoods. Only four of 20 active marijuana farms in the valley are fully equipped with them, county records show.
