The Australian Medical Association’s Tim Greenaway said more trials were needed on medicinal cannabis.
“Whilst we acknowledge the benefit, therapeutically, of medicinal cannabis we do know that there are problems with the different alkaloids that are contained within the cannabis plant.
“The effect the alkaloids have on individuals and the body are not clearly understood.
“We do need more information on how medicinal cannabis works and the effects on the body.
“It’s not a one hat fits all scenario.”
Peter Skillern, the chief executive of the Tasmanian Farmers and Graziers Association, said Canada’s medicinal cannabis industry was made up of relatively small crops.
“I think we have to look at the Canadian experience that for the whole country,” he said.
“Most of their medicinal cannabis is grown within a relatively small area – something in the order of three to five hectares.
“So growing medicinal cannabis in Australia is not going to produce a new agricultural product for Tasmania, or Australian farmers for that matter.”
Given the small area of cultivation needed, he said it was likely Australia would also have only one medicinal cannabis crop and that farmers may not be the ones growing it.
“It would make perfect sense. In other words, you can put it all in one place,” he said.
“All your security costs are restricted to one place and arguably it won’t be grown by farmers — it’ll be grown by lab technicians and the like.”
