Cannabis and Opioid Use Disorder, Study 2

This inpatient study enrolls healthy individuals who have opioid use disorder. Participants live at the University of Kentucky Hospital for approx. 6 weeks. During this time, we will examine how repeated doses of oral cannabis and acute doses of oral and inhaled cannabis 1) modify the intensity and time course of opioid withdrawal, 2) modify the effects of intranasal opioid administration and 3) impact the safety of opioid administration.

Brain Dopaminergic Signaling in Opioid Use Disorders

Background: The chemical messenger dopamine carries signals between brain cells. It may affect addiction. Heavy use of pain medicines called opioids may decrease the amount of dopamine available to the brain. Researchers want to study if decreased dopamine decreases self-control and increases impulsiveness. Objective: To learn more about how opiate use disorder affects dopamine in the brain. Eligibility: Adults 18-80 years old who are moderate or severe opiate users Healthy volunteers the same age Design: Participants will first be screened under another protocol. They will: * Have a physical exam * Answer questions about their medical, psychiatric, and alcohol and drug use history * Take an MRI screening questionnaire * Give blood and urine samples * Have their breath tested for alcohol Participants will have up to 3 study visits. They will have 2-3 positron emission tomography (PET) scans. A radioactive chemical will be injected for the scans. Participants will lie on a bed that slides in and out of the donut-shaped scanner. A cap or plastic mask may be placed on the head. Vital signs will be taken before and after the PET scans. Participants will get capsules of placebo or the study drug. They will rate how they feel before, during and after. Participants will have their breath and urine tested each day. Participants will have magnetic resonance imaging (MRI) scans. They will lie on a table that slides into a cylinder in a strong magnetic field. They may do tasks on a computer screen while inside the scanner. Participants will have tests of memory, attention, and thinking. Participants will wear an activity monitor for one week....

Systems Analysis and Improvement to Optimize Opioid Use Disorder Care Quality and Continuity for Patients Exiting Jail

This study evaluates the effectiveness of a health systems strategy (the Systems Analysis and Improvement Approach - SAIA) that packages systems engineering tools (including cascade analysis, flow mapping, and continuous quality improvement) to optimize the management of opioid use disorder (MOUD) care cascade and improve linkages between jails and clinical referral sites. The investigators will 1. study the effectiveness of SAIA on MOUD care cascade quality and continuity for patients receiving care in jail and exiting to referral clinics 2. explore determinants of adoption, implementation, and sustainment of SAIA-MOUD across implementation clinics, and 3. estimate the cost and cost-effectiveness of SAIA-MOUD
