Around a quarter of people who smoke are non-daily smokers (those that smoke on some but not all days), and that number is increasing. The cancer risk of non-daily smoking is significant and existing treatments tend not to be tailored to this population. \n\nTo address this issue, Bettina Hoeppner, PhD, an experimental psychologist and Associate Professor of Psychology at Harvard Medical School and Massachusetts General Hospital, has developed a smartphone app, \u201cSmiling Instead of Smoking,\u201d to support non-daily smokers in quitting smoking. It serves \u201cas a behavioral, in-the-pocket coach and uses positive psychology exercises to enhance quitting success.\u201d\n\n4:00 \u2013 What are \u201cnon-daily smokers?\u201d Why is this a thing? \n\n5:40 \u2013 Health risks of non-daily smoking\n\n6:51 \u2013 Populations that are more at risk, and why they may be more likely to be non-daily smokers\n\n9:31 \u2013 Barriers to quitting that are unique to non-daily smokers\n\n12:05 \u2013 Why she uses a smart phone app in her research to help non-daily smokers quit smoking\n\n14:28 \u2013 How her \u201cSmiling Instead of Smoking\u201d app works\n\n18:07 \u2013 Why she chose happiness as an approach; how positive psychology is a promising new approach to smoking cessation\n\n22:03 \u2013 On positive early returns her team has seen from the app\u2014confidence in quitting increased, urge to smoke decreased, and perceptions of smoking became less positive\n\n25:40 \u2013 On the potential to reach vulnerable populations with this app\n\n28:13 \u2013 The impact American Cancer Society funding had on her career, taking a chance on funding work that was perceived as high risk\n\n30:03 \u2013 A message she\u2019d like to share with cancer survivors and caregivers
