Temporal Interference Methods for Addiction Treatment

This clinical study is testing whether a new non-invasive brain stimulation method, called temporal interference (TI), can reduce nicotine cravings and usage in people who vape. TI delivers mild electrical currents to the scalp in a way that targets deep brain areas involved in addiction, without the need for surgery. In this randomized controlled trial, participants will be assigned to one of three groups: TI stimulation to the nucleus accumbens, TI stimulation to the anterior insula, or a placebo (sham) condition. Each participant will attend a single stimulation session after 8 hours of nicotine abstinence and will use a custom vape device that measures real-time nicotine inhalation. Craving levels will be reported during and after the session. The study aims to determine whether TI to the insula or nucleus accumbens is more effective at decreasing cravings and nicotine inhalation, and whether either is more effective than sham stimulation. For one week after the session, participants will use a smartphone app to track nicotine use and cravings. The primary hypothesis is that TI stimulation to deep brain regions will reduce both nicotine craving and actual use, immediately after stimulation and over the following week, compared to the sham condition.

Characterization of Phenotypic and Genotypic Regressors for Imaging

The influence of genes on addictive and neuropsychiatric disorders is complex, especially given that multiple genes likely influence certain behaviors that are correlated with addiction. Researchers are interested in looking at the genetic information of individuals who are enrolled on National Institute for Drug Abuse studies to investigate specific genetic variants that may be related to substance abuse. Researchers will study the effects of genes on several aspects of thinking such as attention, memory, decision making, problem solving, learning, and emotional feelings, and investigate the ways in which genetic information affects addictive behaviors and substance abuse. In addition, researchers will study how genes may explain differences in imaging data in substance users. Objectives: \- To collect genetic information for research on genetic aspects of addiction and substance abuse. Eligibility: * Adults age 18 or older * (1) healthy, non-drug-using nonsmokers, * (2) healthy smokers, * (3) healthy individuals dependent on other commonly abused drugs, and * (4) individuals with other psychiatric disorders. * Participants must be enrolled in another National Institute on Drug Abuse, Intramural Research Program imaging protocol. Design: * This study involves one to two visits to National Institute on Drug Abuse, Intramural Research Program that may be separate from the participant's current research protocol study visits or on the same day as those visits. * Participants will provide a blood sample and complete questionnaires about mood, memory, and learning. * Participants may also be asked to do a few tasks, such as playing computer games involving coin tosses and money management, or responding to questions on a computer screen.

Development and Evaluation of a Virtual Reality Tool for At-Risk Trauma-Exposed Young People

This is a multi-phased study, funded through a National Institute on Drug Abuse (NIDA) K24 grant that aims to ultimately refine a virtual reality tool through qualitative and quantitative research targeting HIV and substance abuse risk behavior among at-risk young people who have experienced psychosocial trauma. Participants eligible for this study include young men who have sex with men (YMSM)/individuals who are romantically/physically attracted to men and adolescents with substance use disorder (SUD) between the ages of 15 - 30 and have experienced at least one traumatic event in their lifetime. Frontline healthcare workers who work within these populations are eligible for the study as well.

Intervention for Comorbid Substance Use and Bipolar Disorders

This trial aims to evaluate the effectiveness of a novel intervention for patients with co-occurring bipolar and substance use disorders following a psychiatric hospitalization. Half of the participants will receive a specialized psychosocial intervention program, while the other half will receive an enhanced safety monitoring program, both provided in addition to their routine care.

Enhancing Substance Use Treatment Services to Decrease Dropout and Improve Outpatient Treatment Utilization in Emerging Adults

Emerging adults (ages 18-25) are at higher risk for substance use disorders, including opiate addiction, than any other age group but are also more likely to drop out early from substance use treatment services. This project will evaluate an enhancement to usual services, delivered by peer recovery supports, specifically aimed at improving treatment adherence and reducing dropout in this age group. The study will also answer key questions about risk factors for dropout among emerging adults and the financial sustainability of enhancing services to reduce dropout.

STEPS: Substance Use Trial of E-cigarettes or Pharmacotherapy for Smoking

The purpose of this study is to investigate whether non-cigarette tobacco products, namely e-cigarettes (nicotine vapes), can help people who smoke and are in treatment for substance use disorder quit smoking by switching completely to e-cigarettes as compared to FDA-approved medications, namely nicotine replacement therapy in the form of patches and lozenges. Participation will last 6 months and includes 14 weekly study visits and 2 follow-up study visits (in-person, but virtual study visits are possible). Participants will also complete a short daily diary on their phones each day for the first twelve weeks. To qualify, participants (ages 21+) must be enrolled in an outpatient substance use disorder (SUD) treatment program. The study is being done in four regions across South Carolina: Charleston, Pickens/Easley, Conway, and Greenville.

Clinical and Neurobehavioral Changes With Weight Loss Drug Discontinuation and Reinitiation

The goal of this clinical study with research procedures is to learn how stopping and restarting tirzepatide (a medication that helps regulate blood sugar and appetite) affects brain activity, behavior, and health in adults ages 18-70 who are currently taking tirzepatide. Specifically, the study aims to examine how a short pause in tirzepatide affects hunger, mood, sleep, and daily functioning; how stopping and restarting tirzepatide alters brain chemistry and brain responses to food-related images; and how these changes relate to health measures such as quality of life and emotional well-being. There is no comparison group; instead, researchers will assess changes within each participant across three time points: while taking tirzepatide, after stopping it for 3-4 weeks, and after restarting it for 6-8 weeks. Participants will attend three in-person visits lasting approximately 3-4 hours each, during which they will complete interviews, questionnaires, and cognitive tasks; provide a urine sample (pregnancy screening for females); undergo a brain scan using magnetic resonance imaging (MRI) and MR spectroscopy (MRS); and receive a kit to provide a small stool sample. Participants will also complete two brief check-in phone calls between visits and the online BrainHealth Index between sessions, which includes surveys and cognitive tasks. All changes to tirzepatide use will occur under the supervision of a study physician to support participant safety and comfort, and the total study duration is approximately 13 weeks.

Enhancing Prospective Thinking in Early Recovery

The goal of this clinical trial is to use a novel virtual reality intervention to test for efficacy in reducing alcohol use and increasing abstinence, with concomitant increases in future self-identification, future time perspective, and delay-of-reward, in early recovering stimulant use disorder (SUD) persons. The main question\[s\] this trial aims to answer are: Will the Virtual Reality (VR) intervention decrease the number of stimulant use days? Will the VR intervention produce longer abstinence periods during follow-up visits? Will the VR intervention increase alcohol abstinence rates? Will the VR intervention increase future self-identification? Will the VR intervention increase self-reported future time perspective? Will the VR intervention increase preference for delayed rewards in a laboratory delay discounting task on the study day? Will the VR intervention produce gains in the behavioral effects of future self-identification, future time perspective, and delayed rewards at the 30-day and 6-month follow-ups? Researchers will compare the experimental and control groups to see if there are differences in the results for the questions outlined above.

Massed Prolonged Exposure for PTSD in Substance Use Treatment

The goal of this clinical trial is to learn if receiving Prolonged Exposure Therapy for PTSD in massed format (multiple sessions weekly) is as effective as receiving it with sessions once per week among veterans with PTSD and substance use disorder in intensive outpatient substance use treatment. The main questions it aims to answer are: * Will the massed format help participants complete and benefit from Prolonged Exposure in terms of PTSD symptoms? * Will it help participants reduce substance use? Participants who are in intensive substance use treatment will be asked to complete Prolonged Exposure with either weekly sessions or multiple sessions per week.

Phase Ib/2a Drug-drug Interaction Study of a Combination of 45mg Dextromethorphan With 105 mg Bupropion

The overall goal of this project is to collect initial human data on the effects of novel compounds on safety (interactions with an opioid drug, e.g., buprenorphine) and early efficacy signals (subjective effects on negative affect, craving, and opioid withdrawal) in OUD subjects currently in MOUD treatment with buprenorphine.

Clinic-level Implementation of mHealth to Improve HIV Viral Suppression for Patients With Substance Use Disorders

The current protocol aims to enroll up to 806 participants from 8 study sites in a clinic-supported intervention which will connect them to Vivent Health care team and a cohort of peer mentors for a year-long intervention period to support patient HIV care to maintain viral suppression and clinic appointments.

CARS: Cannabis and Alcohol Reduction Study

The study will test a computerized treatment with subjects ages 13-17 years who are seeking treatment for alcohol and/or cannabis use. Follow-up assessments will be conducted at one- and three-months following treatment.

IMPOWR-ME Project 1: Trial of Yoga and Physical Therapy Onsite at Opioid Treatment Programs

This is a pragmatic, open label, randomized controlled trial with 1:1:1 allocation to 12 weeks of: (1) onsite yoga at opioid treatment programs (OTPs), (2) onsite physical therapy (PT) at OTPs, or (3) treatment as usual (TAU). Participants will be 180 individuals with chronic back pain receiving treatment for opioid use disorder (OUD) in community-based OTPs. Through research visits at screening, baseline, and months 1, 2, 3, 6, and 9, the investigators will evaluate pain and opioid use outcomes and implementation outcomes.

Ketamine for Methamphetamine Use Disorder

This study aims to determine whether treatment response with IV ketamine is superior to treatment response with IV midazolam in adults with moderate to severe MUD. The study design is a 12-week randomized, double-blind, controlled trial comparing intravenous (IV) ketamine against IV midazolam, delivered over six weeks in 120 adults with moderate to severe methamphetamine use disorder (MUD).

Feasibility of an Interdisciplinary Intervention to Improve Care Transitions for Hospitalized Patients With Substance Use Disorders

The purpose of this study is to evaluate the feasibility and preliminary effectiveness of a primary care-based Interdisciplinary Addiction Care Transition (IntACT) team that will meet patients with substance use disorders (SUD) during a medical hospitalization and provide intensive care management, peer support, and interim SUD and medical care after discharge while facilitating a transition to long term community-based treatment.

Interprofessional Simulation Program for Clinical Resilience and Empathy: Project INSPIRE

The goal of this clinical trial is to develop and evaluate INSPIRE, an intervention for healthcare teams to improve care for individuals with substance use disorder (SUD) during their peri-delivery care. The main question it aims to answer is whether healthcare provider stigmas and behaviors change after receiving the training. The study will be implemented at the University of Utah.

Enhancing Addiction Treatment Through Psychoeducation

Addiction is a brain disorder characterized by a broad range of both apparent and subtle cognitive impairments in attention, memory, executive functions, and decision-making. These cognitive problems are clinically significant and may contribute to poor treatment outcomes in people with Substance Use Disorders (SUDs), such as a high risk of dropout, low treatment compliance, and shorter periods of abstinence. Studies on cognitive function in SUDs reveal that chronic use of drugs and alcohol can also negatively affect another crucial component of cognition: awareness, or metacognition. Metacognition is defined as an individual's ability to perceive and understand their cognitive functions and use this understanding to regulate them. One of the key consequences of metacognitive impairments is the lack of insight in people with SUDs, which adversely affects treatment outcomes. Substance users with poor metacognition are more reluctant to initiate or continue treatment and are more likely to deny their cognitive problems. Therefore, improving metacognition may remove or reduce motivational barriers to invest time and effort in the recovery process in general, and in the brain recovery process specifically. Despite the importance of neurocognition and metacognition in the recovery process for substance users, there is a dearth of interventions designed to target these functions.

Project I Test: Implementing HIV Testing in Opioid Treatment Programs

This study will test two active evidence-based "practice coaching" (PC) interventions to improve opioid treatment programs' (OTPs') provision and sustained implementation of on-site 1) HIV testing and linkage to care and 2) HIV/Hepatitis C virus (HCV) testing and linkage to care among patients seeking/receiving substance use disorder treatment. Aims are: Aim 1: To evaluate the effectiveness of the PC interventions on improving patient uptake of HIV testing in OTPs including the incremental impact of the HIV/HCV intervention on HIV testing. Aim 2: To examine, using mixed-methods, the impact of the PC interventions on the initiation and sustained provision of HIV testing and timely linkage to care. Aim 3: To evaluate the health outcomes, health care utilization, and cost-effectiveness of the PC interventions compared incrementally to one another and to the control condition. Primary Hypothesis: 1. The two PC interventions will result in significantly higher proportions of patients tested for HIV than the information control condition during the "initial impact" period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Primary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary). 2. The HIV/HCV PC intervention will result in significantly higher proportions of patients tested for HIV than the HIV PC intervention during the initial impact period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Secondary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary).

Substance Use Prevention for Youth With Parents in Recovery

Risk for substance use disorder (SUD) begins early in the life course. Although preventing and decreasing illicit and nonmedical drug use among youth is an urgent public health priority, there are currently few evidence-based prevention strategies feasible for delivery in the primary care setting. The investigators propose a three-year plan to collect critical pilot data to pilot test and optimize a dyadic intervention that aims to increase family resilience, strengthen coping skills, help families plan for the future, and prevent youth SUD. The 'prototype' for the intervention approach is Family Talk, an evidence-based parent-youth dyadic intervention that can be delivered within the existing infrastructure of the patient-centered medical home. The investigators have made preliminary adaptations to the model in preparation for testing. To prepare for a subsequent efficacy study, a two-arm pilot randomized controlled trial of the intervention with 40 parent-youth dyads to optimize the intervention model will be conducted. The feasibility of the intervention will be evaluated. In addition, empiric estimates of study parameters to inform the planning of a fully powered randomized controlled trial and plausible intervention targets using semi-structured qualitative interviews will be obtained.

COPEWeb Training for Providers

Post-traumatic stress disorder (PTSD) and substance use disorders (SUD) are two of the most common and debilitating mental health conditions afflicting military Veterans. PTSD and SUD frequently co-occur and are associated with poorer treatment outcomes. The investigators' team developed a trauma-focused intervention, Concurrent Treatment of PTSD and Substance Use Disorders Using Prolonged Exposure (COPE), which is identified by the VA as a gold standard of behavioral healthcare and was designated as a first-line treatment in the 2025 APA Clinical Practice Guideline for PTSD. However, a critical barrier to ensuring that Veterans with co-occurring PTSD/SUD receive evidence-based treatment is a lack of provider training. This project directly addresses this critical gap by developing a new web-based training program for providers (COPEWeb).

Promoting Recovery by Overcoming Self-stigma in Mental Health Disorders With a Narrative Enhancement and Cognitive Therapy (NECT) Group Intervention

This study will evaluate whether Narrative Enhancement and Cognitive Therapy (NECT) can promote recovery among adults living with severe mental health disorders, including substance use disorders. NECT is a structured group intervention that combines education about stigma, cognitive techniques to challenge internalized negative beliefs, and narrative exercises that help participants develop a broader identity beyond their diagnosis. Approximately 106 adults receiving outpatient or day-hospital psychiatric care at Geneva University Hospitals will be randomly assigned to receive either usual care plus 12 weekly NECT sessions or usual care plus 12 comparison group sessions that do not specifically address self-stigma or recovery. The study will examine whether NECT improves recovery after the intervention and whether any benefits are maintained over time.

Safe & Sound Protocol in Adults With Trauma and SUD

This study will explore whether the use of the Safe and Sound Protocol (SSP) app is an effective adjunct to treatment as usual (TAU) in individuals with co-occurring substance use disorders and trauma. This study will recruit 129 participants (100 completers) randomized to receive either active or sham SSP in addition to TAU. Participants will utilize the SSP for a minimum of three hours to a maximum of five hours for a total of seven days. Data will be collected at both pre- and post-test. Data to be collected will include measures on affect, anxiety, personality, mindfulness, and posttraumatic stress disorder symptoms. The SSP has shown effectiveness in reducing symptoms of anxiety, depression, and trauma symptoms in pilot studies conducted at other locations. This will be the first study to examine the effectiveness of SSP with individuals with co-occurring SUD and trauma.

Evaluation of the Safety and Effects of Psychoactive Substances in People With Past Opioid Use

The purpose of this study is to understand how kratom affects people. In this study, kratom will be compared with another substance and a placebo (an inactive substance). Researchers will also study how the substances move through and affect the body. This includes examining how the body absorbs, processes, and eliminates the drug (pharmacokinetics), as well as how the drug affects the body and how it may make you feel (pharmacodynamics). The information collected will help researchers better understand the effects and potential risks of kratom.

Developing a Telehealth Model to Improve Treatment Access for Rural Veterans With Substance Use Disorders

This project will pilot-test and obtain stakeholder input on a telehealth-delivered substance use disorder (SUD) care model (with initial engagement and ongoing MI-CBT treatment) with the goal of increasing treatment utilization and improving outcomes for rural and non-rural Veterans with SUDs.
