This study proposes to collect pilot data that will inform a future grant application. We propose to complete interviews (60 min) on 25 individuals who are currently or have previously used opioids and are either currently on MAT or chose to not begin MAT. Semi-structured interviews will identify (1) what individual and treatment factors helped participants initiate MAT or, conversely, inhibited engagement in MAT, (2) what concerns they had about starting MAT, and (3) encouraging them to reflect on what additional information could have helped them initiate MAT sooner. Eligible participants will be compensated $20 for their participation in the study.

The purpose of this study is to develop transcranial magnetic stimulation (TMS), specifically TMS at a frequency known as theta burst stimulation (TBS), to see how it affects the brain and changes the brain's response to alcohol-related pictures. TMS and TBS are stimulation techniques that use magnetic pulses to temporarily excite specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). TBS, which is a form of TMS, will be applied over the medial prefrontal cortex, (MPFC), which has been shown to be involved with drinking patterns and alcohol consumption. This study will test whether TBS can be used as an alternative tool to reduce the desire to use alcohol and reducing the brain's response to alcohol-related pictures.

This study is looking at an investigational medication called EMB-001, which is a combination of metyrapone and oxazepam, to see if it may be an effective treatment for cocaine use disorder. Participants will undergo screening procedures to determine eligibility, and eligible participants will take either EMB-001 or placebo twice a day for 13 weeks. During this time, participants will come to the office two times a week to meet with study personnel, and they will attend a one-month follow-up visit.

The purpose of this research study is to understand if high brain iron in individuals who use cocaine is related to the severity of cocaine use disorder. We will use non-invasive brain MRI to examine if high brain iron is associated with 1) abnormal brain circuits, and 2) behavioral and cognitive problems. The consists of a screening visit to determine eligibility and an MRI scanning visit.

Many adolescents experience traumatic events, such as child abuse, physical or sexual assault, or witnessing violence. Teens who experience trauma are more likely to have problems with substance use and risky sexual activity. We want to understand how parents can support their teens and help keep them safe after traumatic events.

Alcohol Use Disorder (AUD) is a risk factor for Alzheimer's Disease (AD), but more research is needed to identify the potential mechanisms underlying this risk. The present study will use fMRI to examine brain network profiles in mid-life AUD. The goal is to develop techniques to assess risk for Alzheimer's Disease and related dementias. Participation includes cognitive testing and MRI scanning.

The purpose of this study is to investigate natural reward processing in cannabis users. Natural reward processing refers to how a person responds to enjoyable or stimulating non-drug experiences. Two groups will participate in the study: 1) people who use cannabis, and 2) people who do not use cannabis. The study will use personalized scripted imagery which involves developing and listening to a detailed story about a personal experience. Scripted imagery has been used to investigate responses to stress and drug experiences and will be used in this study to investigate responses to naturally rewarding experiences.

The purpose of the study is to examine whether an investigational medication called ketamine, which comes in the form of a nasal spray, is able to improve treatment outcomes for concurrent opioid addiction and depression when used in conjunction with buprenorphine treatment. Study medications will be delivered twice per week for four weeks. If you are eligible and you decide to enroll in the study, your participation will last approximately 8 weeks, or 2 months.

The purpose of this study is to determine the effects of a brain stimulation technique known as transcranial direct current stimulation, or tDCS, on the benefits of Prolonged Exposure therapy, or PE, which is an effective treatment for posttraumatic stress disorder, or PTSD. tDCS has been demonstrated to be safe and effective for influencing brain activity by passing a weak electrical current through the scalp. In this study, tDCS is provided in addition to PE treatment, through the National Crime Victim's Research and Treatment Center at MUSC, or the PTSD Clinical Team Clinic within the Ralph H. Johnson VA Medical Center.

The primary purpose of this study is to compare extended-release buprenorphine (CAM2038) to buprenorphine placed under the tongue (sublingual) in pregnant women with opioid use disorder to see if CAM2038 is as effective as sublingual buprenorphine. We are looking to recruit pregnant women who are between 18-41 years old; are between 6-30 weeks pregnant and are not planning to terminate the pregnancy; have opioid use disorder, and are enrolled or are planning to enroll in outpatient buprenorphine treatment at The Medical University of South Carolina. Participation in the study would last between 13 and 21 months total with up to between about 63-102 total visits, including weekly medication check visits and research visits.
