Opioid Abuse

In this study, the investigators will measure affective, neurocognitive and behavioral outcomes related to chronic use of opioids and benzodiazepines (screening phase), and in response to the administration of the opioid morphine, the benzodiazepine alprazolam, morphine then alprazolam, alprazolam then morphine, morphine+alprazolam simultaneously, and placebo (laboratory pharmacology experiment). The latter will enable the investigators to assess the effects of an opioid alone, benzodiazepine alone, concurrent and simultaneous administration of opioid+benzodiazepine, relative to a placebo control.

This project examines functional connectivity patterns associated with subsequent relapse to illicit opioids during treatment for OUD.

The overarching goal of this project is to increase the availability of OUD treatment in rural counties in the state of Georgia by using Emergency Department (ED)-based telehealth strategies to initiate MOUD and connect patients to treatment. The investigators will implement a novel collaboration between rural EDs, medical toxicologists at the Georgia Poison Center (GPC), peer recovery coaches (PRCs) and RCOs throughout Georgia to bridge the gap between OUD treatment need in rural EDs and specialty physician availability at the GPC. Research activities will be conducted during two broad phases, at three rural EDs in Georgia: planning and implementation. During the planning phase, aggregate data will be obtained to determine each ED's existing practices treating patients with OUD and opioid withdrawal. During the implementation phase, the researchers will prospectively study a poison center OUD consultation and PRC intervention as it is rolled out at each site, collecting participant-level data. Sites will be rolled into the implementation phase in a stepped-wedge fashion, so there will be times when some sites are in the planning phase while others are in the implementation phase.
