Steve Peek says cannabis oil has helped control his daughter Suli's seizures.
The father of a dying Brisbane child wants special permission from the Queensland Government to use cannabis oil in hospital.
Steve Peek said doctors had tried every legal medication on his eight-year-old daughter Suli, who has a regressive neurological disorder that causes multiple chronic seizures, but that nothing had worked.
He resorted to cannabis oil 16 months ago to give Suli a better quality of life, and said it had helped control her seizures.
But following a recent virus, Suli now needs palliative care.
Mr Peek has pleaded with the Government to provide him with compassionate access to use the drug in hospital.
"What we need is some sort of approval so if she goes to hospital we can continue using the cannabis oil," he said.
"It's hard for us to take her to the hospital because they won't allow for us to give her medical cannabis in the hospital.
"If they make us stop using cannabis oil, Suli will die."
Queensland's chief health officer Jeannette Young said the Government did not support an amnesty for anyone using illicit drugs.
"We have made a legitimate pathway for Queensland patients of any age and with a range of conditions to access legal cannabis products," Dr Young said.
"Queensland's medicinal cannabis trial is proceeding as planned for eligible children with severe drug-resistant epilepsy, with up to 30 children expected to take part later this year."
The Australian Medical Association's Richard Kidd would not condone the use of medicinal cannabis oil.
"It's very easy to get the dose wrong from one dose to the next," Dr Kidd said.
"Children in particular have presented in hospitals in comas and died from cannabis oil."
Most people using medicinal cannabis on their sick children will not speak out for fear of repercussions.
