The goal of this study is to evaluate sex and gender differences across adulthood (18+) in reasons for using cannabis and the perceived severity of consequences associated with cannabis use. We are also interested in understanding how these reasons for cannabis use and perceived severity of consequences are related to other mental and physical health factors. Interested individuals will first complete a brief screening survey. Based on the results of this screening survey, eligible participants will immediately be invited to complete the survey remotely online via a secure web-link. Participants can expect to complete the survey in 30-45 minutes and will be reimbursed $30 via electronic gift card (e.g., Amazon).
This study aims to investigate innovative approaches to managing chronic pain and opioid use. This study consists of two phases, each offering different treatment options. Participation is voluntary.
This study will sequentially evaluate three novel and scalable interventions for at-risk individuals on long term opioid therapy for chronic pain: (1) low-dose transdermal buprenorphine initiation without a period of opioid withdrawal; (2) a brief Cognitive Behavioral Intervention for pain (CBI); and (3) transcranial magnetic stimulation by examining standardized repeated measures of clinical outcomes at baseline, during treatment, and at follow-up.
In this initial phase, all participants will have a 1-week open-label trial of buprenorphine (worn as a patch on the arm, shoulder or upper-back). This trial aims to assess the safety and effectiveness of buprenorphine in managing chronic pain and opioid use. During this phase, participants will have the opportunity to experience the effects of buprenorphine under close monitoring.
After completing Phase 1, participants will have the opportunity to choose their next course of treatment. They can decide to continue with buprenorphine, and undergo a 1-week trial of either real buprenorphine or a placebo (an inactive substance). They will be randomly assigned to receive either real or placebo buprenorphine. If participants respond well to buprenorphine treatment, they may continue the medication under the care of their physician.
Alternatively, participants can explore an alternative treatment called repetitive transcranial magnetic stimulation (rTMS) in Phase 2. If they opt for rTMS, they will receive either real rTMS or a sham version interspersed with cognitive-behavioral therapy for pain. Participants will be randomly assigned to receive either real or sham rTMS.
In both phases, participants will receive close monitoring and attend regular study visits to assess safety and progress. Throughout the study, they will be asked to complete questionnaires about pain, functioning and opioid use, undergo physiological monitoring and blood samples will be collected at specific points.
It's important to note that there are potential risks associated with the study medication, such as difficulty sleeping, nausea, and dizziness. Additionally, for the rTMS arm, there is risk of mild headache, pain at the stimulation site, and there may be unknown risks related to the brain stimulation.
Participants' experience in Phase 1 will involve an open-label trial of buprenorphine, and participants' decisions in Phase 2 will determine the treatment path. While the effectiveness of these treatments is uncertain, participants will receive thorough monitoring throughout the study, and have the option to withdraw at any time. Improvement in participant symptoms is possible but not guaranteed.
This study will evaluate the associations and interactions between bar-lab/naturalistic drinking variables with participant characteristics in individuals with bipolar disorder and alcohol use disorder. This study includes 4 study visits over approximately 1 week. Questionnaires and clinical interview measures will be completed at study visits.
