Medicinal cannabis is being used in a trial study in Australia to see whether it helps treat an aggressive form of brain cancer.
Professor Charlie Teo and nutritional supplement company BioCeuticals are undertaking a clinical trial involving 82 Australians aged between 19 and 70 who suffer from Glioblastoma, or GBM.
Nine News reports the product being taken has Tetra Hydro Cannabinols (THC) as its main active ingredient.
Brain scans will be examine throughout the three-month study to see if it has an effect on the growth rate of the tumours.
Belinda Reynolds of BioCeuticals said they are hoping the drug trial could help patients retain their appetite while also undergoing conventional cancer therapy, therefore limiting weight loss.
Professor Teo said "[GBM] is the most aggressive of all cancers known to mankind and has a terrible prognosis
"To be a realistic we are looking at a treatment that may offer people some benefit."
