Euthanasia is derived from a Greek word which means “good death”. To some, it means the idea of mercy killing. It has been commonly used in the field of medicine where a patient’s life is ended because of a serious illness or when the patient is nearly dying, hence anticipating death. In Thailand, euthanasia is not expressly allowed. Neither is it expressly prohibited. However, practicing euthanasia entails different legal consequences. The legal consequences however vary depending on the type of the method use by the parties involved.
