WORCESTER, Mass., May 16, 2019 /PRNewswire/ — In a National Institutes of Health-funded randomized controlled clinical trial, To Quit, MindSciences’ smoking cessation app, has shown a dose-dependent relationship between app use and reduction in cigarette smoking. The trial involved 67 subjects who received either To Quit or QuitGuide, the National Cancer Institute’s smoking cessation app. In the study, an area of the brain, the posterior cingulate cortex (PCC), known to be activated by smoking cues was followed using functional magnetic resonance imaging (fMRI). Dr. Jud Brewer, the study’s principle investigator, associate professor at Brown University and MindScience’s lead scientist explains that, “This study showed a specific effect of mindfulness training on the default-mode brain network at an individual level. The more the network was deactivated through app use, the more of a reduction in smoking observed, a true dose response relationship, yet this was specific to the individuals who received mindfulness training [the To Quit app].” Click here to read the full article. For more evidence on mindfulness-based quitting, see the randomized controlled trial results and our guide to smoking cessation strategies. Smoking is the leading cause of death in the US, accounting for more than 480,000 deaths every year or about 20% of all deaths in the US. Its social and economic impact are immense and current cessation approaches that depend on will power are inadequate. Brewer added, “Both the apps tested had similar effects but only To Quit showed fMRI changes with the PCC. This is the first time that mindfulness training has shown a specific effect on a brain network, predicting reduction in smoking. The fact that brain changes predicted outcomes at the clinical level helps us zoom in on specific mechanisms that can start to individualize treatment and bring it to the level of personalized medicine.” Digital therapeutics delivered as apps represent an accessible and affordable way for millions to benefit from an evidence-based treatment. Brewer, a practicing addiction psychiatrist added, “currently < 1% of apps are backed by evidence and clinical experience. We are really excited about the potential for this approach.”

This study laid the groundwork for Dr. Jud’s broader research into how reward-based learning drives habits and how mindfulness can interrupt the cycle. The same principles have since been applied to anxiety and emotional eating through the Unwinding Anxiety and Eat Right Now programs.
