The possibility of Idaho residents crossing their Western border to take advantage of Oregon’s new law allowing doctorassisted suicide has prompted the Oregon Medical Association to warn doctors to make sure people who ask for assisted suicide actually live in the state.

Oregon is the only state in the nation that allows doctors to help terminally ill patients die. But the assisted-suicide law, which took effect 11 days ago, requires patients to be Oregon residents.

The state has no time requirement to establish residency.

The Oregon Medical Association wants doctors to require driver’s licenses and voter registration cards to show a person lives in the state, spokesman Jim Kronenberg said.

Even if doctors follow the advice, a person could obtain a driver’s license and voter registration card in a minimum of 21 days.

Under the Oregon law, two doctors must diagnose a patient as having a terminal illness that will kill the patient within six months, and another physician, who agrees to administer the drugs, must wait 15 days before prescribing them for the patient.
