The boss of a County Lines drugs gang known as 'Biggie' flooded streets with heroin and crack cocaine.
Adam Jarir, of Kingsland Crescent, Walton, was part of a gang which brought Class A drugs to Wigan, leading to estimated sales exceeding £800,000.
The 29-year-old used homes in the borough to store, prepare and distribute class A drugs in a method known as cuckooing, Bolton Crown Court heard.
