Five people have been sentenced for their part in the bulk supply of cannabis across Hull and East Yorkshire.
Armir Metaj, Patryk Gilwanowski, Endri Arifaj, Gazmir Hameti and Manuela Metaj were sentenced at Grimsby Crown Court on Friday.
Humberside Police said the organised crime group used encrypted messaging platforms to hide their county lines drugs operation, and fake vehicle insurance policies to travel across London, Rugby, Sheffield and Middlesbrough.
PC Claire Dobson said: “We know the impact that drug supply and organised crime have on our communities, from exploitation and violence to the wider harm it brings. Dismantling these networks remains a priority.”
The force said Metaj, 30, of Roscoe Street, Middlesbrough, was the ringleader of the operation and controlled the drugs line.
He was jailed for five years and four months after pleading guilty to conspiracy to supply cannabis at an earlier hearing.
Metaj was also charged with conspiracy to supply cocaine but was found not guilty after a nine-day trial at Grimsby Crown Court.
