The federal government is seeking to ban marijuana shops in Queensland, New South Wales and Western Australia, but not Victoria.
The states are also moving to change the medicinal cannabis laws, but it is not yet clear which will be affected by the change.
Some states, including New South Welsh, have moved to allow medicinal cannabis use for some people with chronic pain.
There is currently no legislation that prohibits medical cannabis use, although some states have moved away from allowing recreational use, in a bid to curb the number of deaths and overdoses related to the drug.
Victoria has also changed its medicinal cannabis legislation.
In Victoria, medicinal cannabis is now legal for all medicinal use, and the medicinal use of medicinal cannabis may be covered by the Medical Treatment Act.
It is also legal for the medicinal supply of cannabis to be transferred to a registered caregiver.
This would mean that any person with a legitimate need for medicinal cannabis can access it, regardless of their age, gender or medical history.
Medical cannabis is a prescription medication that has a low toxicity and high efficacy.
A person with chronic or chronic pain who wants to access it may also need to be registered as a medicinal supply to be able to purchase it.
Under the new rules, medical cannabis will be sold to licensed pharmacies.
According to the new regulations, there will be no limits on the number or quantity of cannabis that can be purchased, nor the length of time it will be used.
New South Wales is also moving towards allowing recreational marijuana use.
Currently, recreational cannabis is only allowed for people with a medical need, and only for recreational use.
There is currently a moratorium on recreational use until after the Victorian Parliament passes a law to allow recreational use in Victoria.
