This study is a non-invasive investigation of participants who currently hold a certification for medical marijuana for various medical and/or psychological conditions. Subjects are assessed at baseline, prior to beginning their medical marijuana treatment regimen and complete clinical and diagnostic scales/interviews, cognitive testing, measures related to quality of life, sleep, general activities, and where appropriate, a neuroimaging session which assesses brain structure, function, chemistry and white matter integrity. Following their visit, subjects track their use of medical cannabis (MC) products daily (type, mode of use, amount, frequency) using a log system, and are in touch with researchers biweekly. Follow up visits occur at 3 months, 6 months, 12 months, 15 months, 18 months, and 24 months post MC treatment initiation in order to better assess the potential impact of MC on cognitive function and related brain and quality of life measures.
Status: currently enrolling research participants
