Under the law, a competent adult Oregon resident who has been diagnosed, by a physician, with a terminal illness that will kill the patient within six months may request in writing, from his or her physician, a prescription for a lethal dose of medication for the purpose of ending the patient's life. Exercise of the option under this law is voluntary and the patient must initiate the request. Any physician, pharmacist, or other healthcare provider who has moral objections has the right to refuse to participate.
