Two people are facing charges stemming back to an accident that happened in April.
Police were called about a car in a ditch on 7th line near 10th Sideroad in Meaford.
The 25 year old driver was charged with careless driving.
Police seized liquid codeine from the vehicle.
After further investigating, officers arrested and charged the 18 year old passenger on Friday with drug possession.
He will appear in an Owen Sound court next month.
