They must agree not to donate eggs for 30 days until after study completion. 12. Male subjects must agree to practice 2 effective methods of birth control (as determined by the investigator or designee) beginning at check-in (Day -1) until at least 3 months after the last dose of study drug. Subject must also agree to inform female partner(s) about participation in the study and ensure they are using a highly effective form of contraception (e.g., hormonal birth control or copper IUD). Male subjects may not donate sperm for 90 days after the end of the study. 13. Subject agrees to and is highly likely (as determined by the investigator) to comply with the protocol defined procedures and to complete the study. Exclusion Criteria: 1. A history of cannabis use disorder or use of any psychoactive drug in the last month. 2. Any reported history of alcohol intolerance. 3. Alcohol intolerance as detected by ethanol patch testing. 4. Subject has a dry mouth or history of salivary gland disfunction or surgery. 5. A history of any psychiatric diagnosis, including mood, anxiety, and psychotic disorders. 6. Any family history of schizophrenia or other psychotic illness. 7. Any history of seizures, epilepsy, or traumatic brain injury. 8. History of syncope within 3 months prior to screening or any history of recurrent and/or unexplained episodes of syncope. 9.

Use or intend to use any medications other than birth control, including prescription, OTC, herbal or recreational products (excluding cannabis) in the 14 days prior to check-in (Day -1), unless deemed acceptable by the investigator. 11. Currently participating in another clinical study of an investigational drug or has been treated with any investigational drug within 30 days or 5 half-lives (whichever is longer) of dosing for this study. 12. Subject has used nicotine-containing products (e.g., cigarettes, cigars, chewing tobacco, snuff, electronic cigarettes) within 6 weeks of Screening. Subjects must refrain from using these throughout the study. 13. Subject is unable to tolerate a controlled, quiet study conduct environment, including avoidance of music, television, movies, games, and activities that may cause excitement, emotional tension, or arousal during the prespecified time points. 14. Subject has known or suspected allergies or sensitivities to the study drug, delta 9-THC or sesame seeds/oil. 15. Subject has a history of consuming more than 14 units of alcoholic beverages per week within 6 months before Screening, has a history of alcohol use disorder or drug/chemical/substance abuse within 2 years before Screening (Note: 1 unit = 12 ounces of beer, 5 ounces of wine, or 1.5 ounce of spirits/hard liquor). 16.

Subject has clinical laboratory test results (hematology, serum chemistry and urinalysis) at screening or check-ins that are outside the reference ranges provided by the clinical laboratory and considered clinically significant by the investigator. Out of range tests may be repeated once for confirmation at screening and/or check-ins at investigator's discretion. 22. Subject has a mean systolic blood pressure \<90 or \>140 mmHg or a mean diastolic blood pressure \<50 or \>90 mmHg at either screening or check-ins, unless determined not clinically significant per investigator. Blood pressure will be measured after the subject has been resting in a sitting position for approximately 5 minutes. Two blood pressure repeats will be permitted in instances where initial measures out of normal range. 23. Subject has a positive test result at screening for HIV 1 or 2 antibody, hepatitis C virus antibodies, or hepatitis B surface antigen. 24. Subject is unable or unwilling to undergo multiple venipunctures for blood sample collection because of poor tolerability or is unlikely to complete the study due to poor venous access. 25.
