So as of 1st of April medicinal cannabis prescriptions became legal.

CBD oil has been legal for a long time, but its not effective on the brain, THC is required. But like CBD works as anti inflammatory for the body cells, THC concentrates on the brain solely I believe.

Anyway here is the info. 

The bottle neck is awaiting Buds. Which isnt expected until October. 

Its a bit like poor ACT where the state legalised Cannabis and 2 plants each, but Federal law still bans it, however in Canberra its the most decriminalised where most just get confiscation. Clearly depending on dealing or personal supply.
