A Queensland grandmother charged with drug offenses is calling for the legalisation of cannabis after benefiting from the drug’s medicinal benefits. 

Debra Leigh Lynch, who suffers from PTSD and a rare auto-immune disease faces charges of producing and possessing the drug and has been fighting the courts since 2017. 

Ms Lynch’s case was adjourned yesterday in the Beenleigh Magistrates Court until February 26, pending the outcome of a Supreme Court appeal that could have implications for her case.

Ms 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.

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