A TEENAGER will appear in court next Friday to face nine drug related charges.

The 19-year-old is to head into the dock at Chelmsford Magistrates' Court on March 21 after being arrested on October 2 last year.

Police were called to New London Road, Chelmsford, after a chemical leak sparked an evacuation at a rehab centre before finding a makeshift lab at a home in North Avenue, Melbourne.

The defendant has been accused of one count of producing a Class B drug, two counts of possessing a Class A drug, five counts of possessing a Class B drug and one count of possessing a Class C drug.
