A Queensland grandmother charged with drugs offences says cannabis has given her so much relief from her medical conditions that she wants it fully legalised.

Debra Leigh Lynch, who suffers from PTSD and a rate auto-immune disease, faces charges of producing and possessing a dangerous drug.

She has been fighting them in the courts following her arrest in June 2017.

Her case was on Wednesday adjourned in the Beenleigh Magistrates Court until February 26, pending the outcome of a Supreme Court appeal that could have implications for her case.

That appeal by Alex Dimitropoulos is against convictions for producing and possessing dangerous drugs and publishing or possessing instructions.

Lynch, who is president of the Medicinal Users Association of Australia, pleaded not guilty to the charges against her during a previous court appearance.

Lynch says she was nearly 30 years old when she first used cannabis after a back injury, weaning herself off an addictive prescription drug that had enabled her to sleep.

Lynch suffers from a rare, painful and terminal auto-immune disease that led to her having her leg amputated, diagnosed post-traumatic stress disorder, anxiety, insomnia and panic attacks.

She tried unsuccessfully to get a prescription for medical cannabis in 2014. More recently doctors told her to go to a cannabis clinic where an initial consultation would cost more than $200.

Legalisation fight

Ms Lynch said legal cannabis supply for medical conditions can cost $3500 a week, which was unaffordable for many.

Lynch says she'll fight for legalisation so people who need the drug for medical reasons can grow their own or get it through co-operatives.

She had letters from doctors saying she had been using cannabis successfully for years when she was arrested and taken to the police station in the back of a paddy wagon.

"We just want to be able to treat ourselves with products that we know work," Lynch said.

"Making it fully legal is the only way the market will be opened up and fair for everyone."
