DANDENONG Tasking Unit uncovered $16,000 worth of drugs after intercepting a car on Stud Road, Dandenong, about 6am on 15 August.
The haul included about 20 grams of heroin and 10 grams of methylamphetamine.
They charged the driver, a 20-year-old Fitzroy man, with drug trafficking and possession and seized $25,000 in cash as proceeds of crime during a later search of his home.
