This study is testing cannabidiol (CBD) as a possible medication to treat alcohol use disorder. Youth (ages 16-22) will receive one dose of CBD (600mg) or placebo (i.e., sugar water) before two different MRI sessions (separated by 2 weeks) to see how CBD affects the brain. The full study will last approximately one month.
Participants must provide informed consent and youth under 18 must have parental consent to participate.
Compensation is available to those who qualify.
The purpose of this two-visit brain imaging (magnetic resonance imaging, MRI) study is to identify brain targets for improving treatment and preventative interventions for individuals at risk for co-occurring bipolar disorder and alcohol use disorder. The preliminary visit for a parent and his/her biological child will include completion of clinical interviews, surveys, and labwork to determine study eligibility. If they are considered eligible for the study, brain imaging visits will occur within 1-2 weeks at which a 1-hour MRI will be completed along with additional clinical interviews, surveys, and labwork. Brief follow-up phone call interviews will be completed with participants every 3 months for 1 year. Study participation is confidential and compensated.
After initial eligibility screening, Veterans who use both cannabis and tobacco will be randomly assigned to receive either varenicline (Chantix) or placebo for 12 weeks. Participants will attend weekly visits to provide breath and urine samples for testing, fill out questionnaires, and meet with study staff about medication compliance.
This research study evaluates the effects of anFDA-approved medication Gabapentin in individuals with Bipolar Disorder who smoke marijuana. Participants in the study will will be assigned to take either Gabapentin or a matched placebo. Study medication will be taken for 17 days. There will be 5 study visits, with 2 MRI brain imaging scans completed. Questionnaires and clinical interview measures will be completed at study visits along with consistent assessment of potential side effects from study medication.
Adults (ages 18+) who would like to reduce their cannabis use (N=224) will be enrolled in an 8-week treatment program. All participants will receive counseling (1 goals session with a therapist followed by 7 weekly computerized cognitive-behavioral therapy sessions). Detailed cannabis assessments (biological and self-report) will be conducted throughout treatment and at 1-, 2-, and 3-months post-treatment completion. Daily electronic diaries will be administered via text message to record detailed logs of cannabis use quantity and frequency. Salivary samples will be collected (and video observed) daily throughout treatment to analyze for progesterone.
The study will test a computerized treatment with subjects ages 13-17 years who are interested in seeking treatment for alcohol and/or cannabis use. Follow-up assessments will be conducted at one- and three-months following treatment.
The study will compare Repetitive Transcranial Magnetic Stimulation (rTMS) with placebo rTMS in reducing Cocaine and/or Methamphetamine use. Study participants will be adults who currently use Cocaine and/or Methamphetamine. Eligible participants will receive multiple sessions of repetitive Transcranial Magnetic Stimulation (rTMS) or placebo rTMS over the course of an 8-week treatment period and will complete follow-up assessments for 8 weeks post-treatment. Participants will be compensated for participating.
Human subjects are being recruited for the proposed study to participate in usability testing for a virtual reality technology tool to be refined for assessment and prevention of risky sexual and substance use behaviors. Specifically, 15 adolescents, 15 young men, and 15 front line health care providers will participate in qualitative interviews and focus groups. Targeted enrollment is based on estimates from the existing clinical population treated by the local clinics from which participants will be recruited and the candidate's experience conducting clinical studies at these sites.
This Phase II clinical research study evaluates both the safety and effectiveness of an FDA-regulated medication presently in the initial stages of development for alcohol use disorder treatment (GET73), and will test whether GET73 alters brain chemicals and function, response to alcohol ingestion, and the desire for alcohol. Participants will be randomly assigned to one of two medication treatment groups (GET73 or placebo). Study medication will be taken for 8 days, with approximately 4 study visits, and a "bar-lab" procedure and 2 MRI brain imaging scans will be completed. Questionnaires and clinical interview measures will be completed at study visits along with consistent assessment of potential side effects from study medication.
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.
