Why do I need to sign a consent form to access medical cannabis?

As there are only two cannabinoid-based medicines currently registered with the Therapeutic Goods Administration (TGA) for treating multiple sclerosis or intractable epilepsy in Dravet Syndrome, doctors willing to prescribe unapproved therapeutic goods such as pharmaceutical grade medicinal cannabis, take on the legal liability. If they work within a hospital or within a research study, the organisation takes on that responsibility. Patients are required to make informed decisions about their treatment in consultation with the treating doctor. Therefore, signing of a medical consent form is required.
