Police have smashed an organised criminal gang that was supplying heroin on the streets of Llanelli .
Seventeen people have been locked up and another four given suspended prison sentences as a result of Operation Cryptic.
The eight-month-long Dyfed-Powys Police operation targeted those involved in the sourcing, trafficking, storage, preparation and dealing of the Class A drug.
The final member of the gang was sentenced at Swansea Crown Court on Friday bringing to an end months of sentences linked to the case.
The names and faces of the full network of dealers can now be revealed.
Dyfed-Powys Police chief inspector Richard Hopkin welcomed the sentencings, saying drugs brought misery to families and communities.
He said: "Today marks the successful outcome of Operation Cryptic after these 21 defendants have been sentenced to over 70 years in prison collectively.
"This means that we have successfully disrupted a series of widespread and far-reaching conspiracies to supply and distribute vast amounts of drugs in the Llanelli area.
"Our serious and organised crime team are to be congratulated on the result of this challenging and demanding prolonged operation, where they used a range of tactics available to them to infiltrate the group's operation."

Chief inspector Hopkin said: "Drugs misuse creates misery and despair and causes significant harm to our communities.
"And despite highly successful previous operations, the community of Llanelli continued to tell us of their concerns in respect of visible drug related harm in the town.
"Intelligence also suggested that heroin continued to be readily accessible in the town and these factors resulted in this investigation and robust action. A number of divisional and specialist resources and departments played a part in making this successful.
"We hope that this sends a clear message to those involved in supplying and distributing drugs – there is nowhere to hide and we will take robust action.
"We are determined to continue to ensure the Dyfed-Powys Police area remains a hostile environment for those involved in the misuse of drugs. Drugs will not be tolerated and anyone concerned in it will be brought to justice for the harm caused to individuals, families, and our communities."
