History of severe or unstable medical conditions that might be compromised by participation in the study (e.g., cardiovascular, hepatic, renal, respiratory, endocrine, neurologic or hematologic disease; history of seizure disorder).\n5. Past 6-month substance use disorder (any severity) with the exception of mild alcohol, cannabis, or tobacco use disorder, which will be permitted in the study.\n6.
