A so-called 'rave' dance party west of Coffs Harbour was the target of a weekend police operation.

On Saturday afternoon officers involved in Operation BORASCA stopped over 250 vehicles on Friday Creek Road at Upper Orara, west of Coffs Harbour.

The drivers were subject to random breath tests and then police and sniffer dogs searched their cars for drugs.

Police say they seized over $30,000 worth of drugs including cannabis, ecstasy, LSD, cocaine and marijuana-laced chocolate.

19 people have been charged with drug offences; and 22 issued with cannabis cautions.

Two 21 year old men and a19 year old have been charged with drug supply and possession and are due to face the Coffs Local court on July the 21st.
