The use of medicinal cannabis has been a controversial subject for many years now.
In the US, there have been major changes to State laws, but as a nation, that country is still waiting for Federal legislation.
Here in Australia, an even more cautious stance has seen legislation for the use and supply of medicinal cannabis to be legalised.
Cannabis Access Clinics have opened centres in Sydney and Melbourne last week, with other states to follow.
In Brisbane they start operating later in August.
Dr Gull Herzberg is a GP who sees the centres as being beneficial for doctors by handling the complex administration involved in prescribing the drug for patients. He's speaking with Phoenix Radio's John Laird.
