SEVEN people have been jailed for a total of 18 years for their parts in heroin deals in Swansea and West Wales.
Judge Keith Thomas said the addictive drug caused people to commit crimes to get money to pay for it, and put pressure on vital services.
Leyla Williams, of Clwyd Road, Penlan, Katrina Bolton and Christopher Harris, of Hollet Road, Treboeth, Daniel Lawrence, of no fixed abode, Gareth Partington, of Howarth Close, Milford Haven, John Lloyd, of Prospect Place, Pembroke Dock, and Alison Hughes, of Greenhill Crescent, Haverfordwest, were all jailed after admitting supplying, or being concerned in the supply of heroin.
Robin Rouch, prosecuting, said officers began conducting investigations in November last year, following suspicions that Hughes, aged 27, was supplying heroin.
He said she travelled to Swansea on a regular basis to source heroin from 34-year-old Williams. She would travel either on public transport or have lifts from Lloyd or Partington.
"Hughes would provide them with or sell them heroin, or other types of reward," said Mr Rouch.
Lloyd, aged 41, had driven Hughes nine times and 30-year-old Partington on four occasions.
She would travel to Clwyd Road, Penlan, where Williams and Harris would supply the drug.
The defendant Lawrence's basis of plea was that he sourced heroin from Williams for other drug users in West Wales.
Bolton was a drug user known to Hughes and on two occasions she sourced heroin from the 40-year-old when she fell out with Williams.
Chris James, mitigating for Hughes, a mother-of-one, said she was a user herself and was addicted at the time she was dealing.
"She's acknowledged that drugs had taken over her life," he said.
"She accepts she's been a terrible role model, she's let herself down, she's let her family down and in particular her daughter."
Ian Wright, for Williams, said she too had two children but had been addicted to heroin for some time and was supplying to fund her ongoing addiction.
Karina Hughes, for Harris, said her client was also an addict and had used the time in custody so far to wean himself off the drug.
Geraint Walters, for Lloyd, said it was a low in his personal life, while Dyfed Thomas, for Partington, said his client had difficulty with heroin.
Catherine Richards, for Bolton, said: "She is not a street dealer, this was in effect assisting another user to obtain drugs for her own use."
Hughes and Williams were both jailed for 40 months, Harris and Bolton for 28 months each, Partington and Lawrence for 32 months and Lloyd for two years.
