"Regulating cannabis will give government more control and increase government revenue, which can be used to fund drug prevention and treatment".
Senator Di Natale said it was more harmful to continue banning the use of cannabis, and called on Australia to "get real".
After the health ministers' meeting on Friday, Hunt announced that all states and territories had now agreed to a NSW and commonwealth joint trial to provide faster access to medicinal cannabis.
Senator Di Natale said nearly seven million Australians had tried or used cannabis, with consumption and drug possession-related arrests both on the rise.
The party wants marijuana to be available for recreational use for anyone over the age of 18.
The party's leader Richard Di Natale unveiled a new drug law reform policy yesterday to decriminalise the drug for adults in Australia, saying those convicted of drug use have to live with a criminal record, which can hurt their ability to get jobs.
Former Australian Federal Police commissioner Mick Palmer backed the Greens' policy, slamming the so-called "war on drugs" as an abysmal failure. "It drives people away from getting help when they need it and exposes them to a risky black market".
"The mayor and police decided the use of soft drugs has a negative impact on the living environment", the spokesman said.
The plan will establish an Australian Cannabis Agency to issue licenses for production and sale of cannabis, monitor and enforce license conditions and review and monitor the regulatory scheme to ensure it is functioning properly.
"The Greens' plan to legalise cannabis for adult use is a major step forward for drug law reform in Australia".
Numerous the party's proposed rules for recreational marijuana are similar to those that already apply to the sale of tobacco and alcohol products.
All sales staff would be required to undertake a "responsible sale of cannabis" course, as well as mental health first aid training.
People would also be allowed to grow up to six marijuana plants at home for their personal use under the new policy, which was announced by Richard Di Natale on Monday.
GST would apply to all cannabis sales.
It would then be able to tax the sale of legal weed, generating millions for the Federal Budget and injecting that back into harm reduction programs.
Prominent drug decriminalisation advocate Dr Alex Wodak, who has also fought for legal pill testing at music festivals, has praised the policy.
