Police have now charged three people, after they were caught up in a screening operation at Cessnock gaol over the weekend.
Officers say the trio committed offences ranging from driving while suspended to drug possession.
A 34-year-old man was allegedly found with two grams of methamphetamine, while another was charged with bringing tobacco into the prison.
They’re both off to court.
A small quantity of cannabis was also seized from a vehicle, however no charges were laid due to insufficient evidence.
Correctional Officers and NSW Police say they’re planning to hold more operations like this in the near future.
