Forty-eight syringes filled with cocaine were found when police raided a trailer park near Prince Albert, Sask., earlier this week.
Now two men and two women have been charged with drug trafficking-related offences or possession offences.
Police said they found the drugs Tuesday while executing a warrant at a property at the Whispering Pines Trailer Park, just north of the city.
Also seized was about 45 grams of cocaine and some merchandise that was confirmed as being stolen.
The four will appear in Prince Albert provincial court on Feb. 18.
