Drugs and cash have been seized as part of a national crackdown on cannabis cultivation.
More than 2,200 cannabis plants were seized across Lancashire when 14 warrants were carried out across the county.
The raids were part of Operation Mille which is tackling the production of cannabis in the UK by organised crime gangs.
Lancashire Police carried out warrants in Preston, Chorley, Lostock Hall, Blackpool, Thornton Cleveleys, Blackburn and Haslingden, in late February.
At an industrial unit in Haslingden, nearly 250 cannabis plants were found across two floors.
Purpose built living quarters were found in the premises.
Around 100 plants were seized from a property in Thornton Cleveleys, and another 70 found at a Blackpool address.
Nine people were arrested on suspicion of drug offences as a result of the warrants.
Detective Inspector Steven Harry said: “Large cannabis growths can be traced to organised crime gangs which are heavily connected to violence, exploitation and anti-social behaviour.
“It fuels other criminal activity – county lines and other drug trafficking, modern slavery, human trafficking, the exploitation of the young and vulnerable.”
