Re-elected MP Fiona Patten has put drug law reform at the top of her political agenda by introducing a bill to legalise marijuana in Victoria, which she hopes will gain the support of the new Parliament.

Ms Patten wants cannabis legalised so that it can be cultivated and manufactured while subject to regulation.

She will introduce the private member's bill to the Victorian Parliament’s upper house on Wednesday afternoon – the first sitting day of the new Parliament.

The change would contribute $204.6 million to Victorian coffers over four years, Ms Patten argued.
