Green Light Therapy As a Non-Pharmacologic Intervention to Decrease Anxiety in Pregnant Women With Opioid Use Disorder

This is a clinical trial evaluating anxiety reduction for women with opioid use disorder affecting pregnancy. It is well documented that anxiety increases as pregnancy progresses. The investigators hypothesize that women who undergo green light therapy (experimental arm) will have a smaller increase in anxiety scores compared to the women who undergo white light therapy (control arm). The investigators will also look at how much opiate replacement therapy increases women require during the study period, and how much opiate they require during admission for delivery. The investigators think this a is a low risk intervention in a pregnant population that has higher levels of anxiety when compared to the general population. The investigators believe based on animal studies that this could be effective, and change the way providers treat and support individuals with substance use disorder. The opioid epidemic has negatively impacted our society at many levels. Finding non-pharmacologic ways to support patients while in recovery/sustained sobriety that are simple and low cost would be a step forward in providing compassionate and comprehensive treatment to individuals affected by Opioid Use Disorder.
