Police say they have made the largest single seizure of heroin in Swansea.
Officers discovered "a significant quantity" of the Class A drug plus crack cocaine following an operation.
Two men, aged 26 and 57, have been charged and remanded in custody after a vehicle was intercepted at Clasemont Road in Morriston on Tuesday.
Acting Chief Inspector Darren George said he was in no doubt the drugs were "destined for the streets of Swansea" and the seizure would disrupt supplies.
"This operation conducted by the city's drugs team in partnership with local officers highlights our continued daily efforts to ensure those who are intent on supplying drugs are actively targeted.
"There is a commitment that officers will continue to target those who supply drugs in Swansea and its wider communities as well as those who bring drugs into the area from outside the city."
The two men, one from the Penlan area and the other of no fixed abode, were remanded in custody when they appeared at Swansea Magistrates Court.
Supt Phil Davies, based at Swansea's central police station: "This is a significant result and has disrupted the supply of a large quantity of drugs in our city.
"There has been a lot of public concern expressed recently regarding the supply and use of drugs in Swansea and this operation sends out a clear message that we will target those individuals who deal drugs and bring misery to our communities."
He said the public had a part to play by informing police of suspicious activities.
