In response to the recent change in U.S. Air Force Instruction 40-102, Tobacco Use In the Air Force, the 633rd Medical Group will transition their entire campus at Langley Air Force Base to a tobacco-free zone, beginning Sept. 26, 2013. The removal of tobacco use on the medical campus will encourage healthy behavior for both the staff and patients. (U.S. Air Force photo by Airman 1st Class Kimberly Nagle/Released)
