Neighbours of a hemp farm in Brough have said the "cannabis smell" emanating from the greenhouses there has left them feeling nauseous.
Brough residents living to the west of the site between Brough and Welton said the smell had become particularly "pungent" in recent weeks - though the farm has been operating there since 2014.
The company running the site, Yorkshire Botanicals Ltd, grows hemp plants - which is different from illicit cannabis and cannot be smoked to get 'high' - for use in the development of medical products.
One man, who did not want to be named, said he lives half a mile away but was unable to open his windows during the recent hot weather because of the smell.
"It's so intense, it's unbelievable," he said.
