Police charged 20 people and impounded five vehicles as part of Operation Buchan in Epping last week.
Community concern around a recent rise in anti-social behaviour, drug use, impaired driving and theft offences around Cooper Street led to the operation.
Police undertook the operation on November 21 and 22.
Over two nights, 20 alleged offenders were charged with offences including possession of drugs, unlicensed driving, theft and possession of weapons.
Five vehicles were impounded as a result of licence and drug-driving offences.
A series of drivers found in possession of cannabis led to police executing a search warrant at a nearby Cooper Street address on November 23.
Officers allegedly located a traffickable amount of cannabis and other prescription medication.
A 53-year-old Epping woman was charged with trafficking cannabis.
She was bailed to appear before Heidelberg Magistrates’ Court on March 3.
