What police believe to be fentanyl was among the drugs seized when Prince George RCMP executed a search warrant late Thursday night on a 2200-block Tamarack Street home.
The synthetic narcotic is 50 to 100 times more toxic than other opioids, such as heroin.
Cocaine, methamphetamine, a loaded .44-calibre revolver, ammunition for the gun, a significant amount of cash and drug trafficking paraphernalia were also found in the home.
Four men and two women, all known to police, were arrested and held overnight.
The bust was part of an ongoing investigation.
