Six people were arrested and officers recovered a substantial amount of Class A drugs, cash and other assets.
Two women and a man appeared at Llandudno Magistrates Court on Friday.
Nerys Wyn Jones (46) of Bangor and Serina Medforth (55) of Bethel are both accused of conspiracy to supply heroin while David Hughes (53) of Bethesda is charged with conspiracy to supply cocaine.
Elsewhere, Barry Clarke (59) of Liverpool appeared before Mold magistrates on Friday accused of conspiracy to supply heroin.
Arthur Hughes (75), from Rachub near Bethesda but currently of HMP Berwyn near Wrexham, was charged with conspiracy to supply Class A substances.
A sixth person arrested during the early morning raids has been released on bail while investigations continue.
Superintendent Arwel Hughes of North Wales Police said: "This activity formed part of our ongoing, proactive response to organised criminality operating across the region."
"We remain determined to dismantle the criminal networks that exploit vulnerable people and cause harm in the community."
"We will continue to work closely with partner agencies, local businesses and residents to relentlessly identify, disrupt and pursue those suspected of being involved in drug supply."
"Drugs blight neighbourhoods, destroy lives, and create cycles of exploitation. Those who seek to sell drugs to the vulnerable are not only breaking the law – they are actively perpetuating the harm that devastates families and erodes community safety."
