Cannabis cultivation in Victoria has won cross-party backing, the support of farmers and doctors, but requires changes to federal laws.

On Friday, The Age reported the Andrews government was preparing to announce a cannabis cultivation trial, potentially clearing the way for a state-based medicinal cannabis-oil industry on the back of a Law Reform Commission report.

The move follows Premier Daniel Andrews' election promise to legalise cannabis oil for use in exceptional circumstances to treat conditions such as cancer and Parkinson's disease.
