Health Minister Steven Miles on Tuesday introduced a bill to repeal the Public Health (Medicinal Cannabis) Act 2016, and make other reforms.

Under the changes, specialists would be able to prescribe medicinal cannabis to patients the same as other controlled or restricted medicine, such as codeine.

Mr Miles said the change would significantly streamline the prescription process by removing state-level approval, with the federal Therapeutic Goods Administration to be responsible for the prescription process.

"It will remove red tape for patients and doctors seeking access to medicinal cannabis treatment," he said.

"It will also mean that visitors to Queensland who have a valid prescription for medicinal cannabis from another jurisdiction will no longer require a specific Queensland approval."

In 2016, the Queensland government passed legislation to allow doctors to prescribe medicinal cannabis to patients, at a time when the drug was a schedule 9 prohibited substance.

Later that year, the federal Therapeutic Goods Administration rescheduled botanical cannabis products and botanically derived cannabis extracts as schedule 8.

Mr Miles said it now made sense to allow a nationally consistent approach.

"Repealing the Act [in Queensland] will ensure there is no unnecessary duplication with Commonwealth requirements," he said.

The bill also removes the requirement for pharmacists to hold an approval to dispense medicinal cannabis and researchers to hold an approval to conduct a clinical trial.

It would remain illegal for the Queensland public to grow cannabis for medical purposes.

Last month, there were 329 applications from across Australia for unapproved medicinal cannabis accepted by the TGA, up from 60 in January.

Patients have had medicinal cannabis approved to treat symptoms of chemotherapy-induced nausea and vomiting, uncontrolled epilepsy in children and anorexia associated with chronic illness.

The bill would also dorce companies or people responsible for pollution to take responsibility for notifying the public of health risks.

Its introduction came after spills of toxic firefighting foam in recent years led to questions about which authorities were responsible for notifying the public.

The bill would also establish an occupational dust lung disease register, fulfilling recommendations from the Coal Workers' Pneumoconiosis Select Committee's Black Lung, White Lies report.

It proposes a compulsory notification regime for occupational dust lung disease and require annual reports to Parliament with the number of cases reported.

In September, it was revealed WorkCover Queensland had received 22 compensation claims for compensation for silicosis from workers in the engineered stone benchtop industry in just three weeks.

If passed, the legislation would allow body parts used at a school of anatomy to be lawfully cremated without a corresponding death certificate or the approval of an independent doctor.

The bill will be debated in 2019.
