Doctors in Australia have started prescribing MDMA and psilocybin - more commonly known as street drugs ecstasy and magic mushrooms - to treat mental illness. The psychoactive compound from mushrooms will be used to treat depression and MDMA will be used for post-traumatic stress disorder (PTSD).
The changes come into effect on Saturday, making Australia the first country to classify psychedelics as medicines.
Up to two million people in Australia could qualify for the new drugs, which can be prescribed by psychiatrists.
