A landmark assisted dying bill has passed through the lower house of Australia's second-most populous state of Victoria after a marathon all-night debate. <br/><br/>Lawmakers in Victoria discussed the voluntary euthanasia bill for 26 hours from Thursday morning until it was approved 47-37 in a vote on Friday. <br/><br/>It will only become law if it is supported in Victoria's upper house. Victoria will become Australia's first state to legalise assisted dying if the next vote is successful.<br/><br/>The proposed law would allow terminally ill patients who are in severe pain to request lethal medication from doctors. They must be aged at least 18.
