You may be eligible if
1. For subjects in BD group, DSM-5 criteria for Bipolar Disorder as determined by the Structured Clinical Interview for DSM-5 (SCID).
2. Young Mania Rating Scale (YMRS) \< 12.
3. Infrequent cannabis use as defined by a history of cannabis use and current use no more than 4 times per month.
4. Willing to abstain from cannabis use for at least two days prior to the experimental visit.
You may not be if
1. Hamilton Depression Rating Scale (HDRS) score \> 10.
2. Suicidality. Exposure to cannabis does not lead to depression but it may be associated with suicidal thoughts and attempts. Therefore, the Center for Epidemiological Studies-Depression Scale (CES-D) subscale measuring suicidal ideation ("I wished I were dead". "I wanted to hurt myself") will be completed. Should any of these items be answered affirmatively, e.g., the subject has endorsed these items for at least 1-2 days in the last week, the subject will not be enrolled in the study.
3. The Substance Abuse Module of the Diagnostic Interview Schedule for DSM-5 will be administered to exclude individuals with current substance use disorders.
4. Clinically significant or unstable medical condition. Subjects will undergo a medical evaluation (H\&P, toxicology screening, and for females of childbearing potential, pregnancy testing (utilizing a human chorionic gonadotropin (hCG) urine test). Individuals with significant cardiovascular disease (e.g., angina, myocardial infarction or stroke), hepatic or renal disease, uncontrolled hypertension, and chronic pulmonary disease (e.g., asthma, COPD), will be excluded. With respect to cardiovascular and pulmonary status, a clinician will screen participants with a tool developed for this purpose (Appendix 3 Cardiopulmonary Screen). Hepatic and renal disease will be evaluated with liver and renal function laboratory tests. Females who are pregnant or lactating will be excluded.
5. Infections - evidence of skin infection at lumbar puncture site.
6. To avoid confounding of cognitive testing, a neurological disorder such as seizures, stroke, Parkinson's disease, dementia, or a history of head injury with loss of consciousness for at least 15 minutes will be excluded.
7. Unwilling to refrain from driving or operate heavy machinery for four hours after consuming study medication. This criterion is consistent with current expert recommendations on driving following the use of cannabis.
8. Additionally, because the hBPM paradigm requires participants to be ambulatory, those who cannot ambulate independently (e.g., require a wheelchair) or those who have a motor disease (e.g., multiple sclerosis, cerebral palsy) will be excluded.
9. A previous adverse reaction to cannabinoids will be cause for exclusion as will a historical diagnosis of cannabis use disorder.
10. Positive result on Draeger 5000 test indicating recent cannabis use.
11. Unwillingness to prevent pregnancy during the cannabinoid administration portion of the study (using birth control in female participants of child-bearing age) Acceptable methods of birth control are: oral contraceptive pills, diaphragm, condom, progestin implant, intrauterine contraceptive device, sterilization, etc.
12. Any active opportunistic infection or malignant condition requiring acute treatment.
