Queensland Premier Campbell Newman has offered support for clinical trials of medicinal marijuana being considered in New South Wales.
A working group is looking into the logistics of a trial of medical cannabis for terminally-ill patients in NSW, after mounting community pressure.
The group, directed by Premier Mike Baird, is due to report back by the end of the year after investigating problems around drug supply and distribution.
Mr Newman said he was prepared to support the plan, but ruled out any broader legalisation of the drug, citing the significant health issues associated with it.
"There's plenty of evidence around now about the psychosis and schizophrenia impacts on people who use marijuana, and it's not just people who are big users of that drug," he told reporters on Tuesday.
