A South Australian man has been charged with possessing drugs and is to appear at Wentworth Local Court.

His arrest follows an incident last Thursday night around 10pm when Police detected a suspicious vehicle stationary on the Sturt Highway at Buronga. 

The two male occupants were spoken with and one was observed to appear to be under the influence of a drug. 

After certain inquiries Police formed a suspicion there may be drugs in the vehicle and a search was conducted. 

A bag containing a white powder was discovered which Police will allege is cocaine, and a small amount of cannabis.
