Narrative:

Cabin and cockpit smoke from unknown origin. Flight attendant in charge notified captain of smoke in the cabin, passing FL250. Captain immediately initiated descent and a turn back to atl (the departure airport). Emergency was declared and emergency procedures were initiated. Returned to atl safely with no injuries. The present oxygen mask and goggles are grossly inadequate for smoke of any intensity. Especially disconcerting was the inability to control the flow of communication between 3 sources: ATC, the cockpit, and the cabin. Too much verbal noise and distrs to focus on the goal of getting on the ground safely. Smoke will continue to be a killer until procedures and equipment are adequately addressed with funding and commitment.
