25 people were arrested in a summer crackdown on county lines drug dealing in Cardiff and the Vale of Glamorgan.
South Wales Police say organised crime officers in the region put 21 so-called drug lines out of business during the month-long operation in July.
One of the disrupted lines was run by Barry drug dealer Jack Thomas, who was jailed for two-and-a-half years after he pleaded guilty to offering crack cocaine via text messages.
He nicknamed his drug line as 'Fatz', which was tattooed on the fingers of his left hand.
The force says the organised crime team in Cardiff and the Vale seized a quarter of a kilogram of crack cocaine during the operation, along with £17,000 in cash.
