Eight members of a gang that brought heroin and crack cocaine from Liverpool to Plymouth have been jailed.
The gang had planned to flood the streets of the city in a £1m-a-year operation.
Sentencing the eight at Plymouth Crown Court Judge Paul Darlow said they had brought "misery" to the streets of Plymouth.
Another five of the gang, including the ringleaders, were convicted and sentenced in June.
During a five-week trial, the court was told couriers made more than 100 trips between them to bring the drugs south from Liverpool.
In one police operation, 3kg of cocaine, 1,400 wraps of crack cocaine and 255 wraps of heroin with a street value of £175,000, were found concealed in a car on the M5.
Carl Barlow, 22, of Savage Road, St Budeaux, Plymouth - but originally from Liverpool - was jailed for 11 years.
Patrick Mooney, 22, of Berkshire Drive, Ford, Plymouth, was sentenced to eight years and one month.
Joseph Pines, 22, of Archer Place, North Road West, Plymouth was sentenced to six years and eight months.
Twenty-year-old James Griffin, of East Lancashire Road, Liverpool was jailed for four years and eight months.
Patrick White, 19, of Wolseley Crescent, Liverpool, and 20-year-old Karl Corson, of Tresillian Street, Cattedown, Plymouth were both sentenced to four years.
John Ward, 19, of Embankment Road, Plymouth, and 43-year-old Alison Bates, 43, of Mintor Road, Liverpool, were each jailed for three years and four months.
Barlow had denied conspiracy to supply Class A drugs, but the other seven defendants admitted the charge.
Devon and Cornwall Police said the Plymouth drug operation was "sophisticated and significant" and one of the biggest it had dealt with in the city.
