Australia's "most progressive" medicinal marijuana legislation, which would give more sick Queenslanders access to the presently illegal drug, has been released for public comment.

If passed, the Public Health (Medicinal Cannabis) Bill 2016 would create a formal process for Queensland doctors to prescribe medicinal cannabis for their patients' treatment.

The Queensland government is set to release its proposed legislation to allow the use of medicinal cannabis.

The government last year announced medicinal cannabis trials at the Lady Cilento Children's Hospital for children with drug-resistant epilepsy.

The Australian Medical Association of Queensland welcomed that trial, but warned against a "laissez-faire" approach to the drug and urged proper scientific trials.
