The Oregon parks department is contemplating a rule to ban smoking out in the open air on hiking trails, picnic areas and common areas of campgrounds.
Spokesman Chris Havel said Wednesday the agency is following through on an executive order from the governor to reduce the public's exposure to secondhand smoke.
He adds that a smoking ban would also help limit the problem of discarded cigarette butts that never really go away.
A series of public hearings is contemplated in the second week of January, and the parks commission is to take up the issue at its February meeting.
Havel says the rule wouldn't take effect until 2015.
The proposed ban would not apply to personal campsites or the beach, which is a state park.
