Double contraception is defined as a condom AND one other form of the following:  Established hormonal contraception (i.e. approved oral contraceptive pills) Long-acting implantable hormones, injectable hormones; A vaginal ring or an intrauterine device ([IUD], with or without hormones); Documented evidence of surgical sterilization at least 6 months prior to Screening (e.g., tubal occlusion, hysterectomy, bilateral salpingectomy, or bilateral oophorectomy for women or vasectomy for men [with appropriate post-vasectomy documentation of the absence of sperm in semen] provided the male partner is a sole partner).  Women not of childbearing potential must be post-menopausal for ≥ 12 months. Post-menopausal status will be confirmed through testing of follicle-stimulating hormone (FSH) levels ≥ 40 IU/mL at Screening for amenorrhoeic female participants. Females who are abstinent from heterosexual intercourse will also be eligible.  Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not considered highly effective methods of birth control. Participant complete abstinence for the duration of the study and for 1 month after the last study treatment is acceptable.  Female participants who are in same-sex relationships are not required to use contraception.  Males must be surgically sterile (> 30 days since vasectomy with no viable sperm), abstinent, or if engaged in sexual relations with a woman of childbearing potential (WOCBP), the participant and his partner must be surgically sterile (e.g., tubal occlusion, hysterectomy, bilateral salpingectomy, bilateral oophorectomy) or using an acceptable, highly effective contraceptive method from Screening until study completion, including the follow-up period. Acceptable methods of contraception include the use of condoms and the use of an effective contraceptive for the female partner that includes: OCPs, long-acting implantable hormones, injectable hormones, a vaginal ring, or an IUD.  Males who are abstinent from heterosexual intercourse will also be eligible and must agree to complete abstinence for the duration of the study and for 1 month after the last study treatment.  Male participants with same-sex partners are eligible when this is their preferred and usual lifestyle.  Women of childbearing potential must have a negative pregnancy test at Screening and Day -1 and be willing to have additional pregnancy tests, as required, throughout the study, at the Investigator's discretion; Males must not donate sperm and females must not donate ova for at least 90 days after the last dose of study drug; Must agree to adhere to the current state and national advice regarding minimizing exposure to corona virus disease of 2019 (COVID-19) from the first Screening visit until the EOS visit; Must be willing and able to provide written informed consent after the nature of the study has been explained and prior to the commencement of any study procedures; Must be in good physical and mental health as determined by absence of any clinically significant (in the opinion of the Investigator) abnormalities based on medical history, physical examination, vital signs, electrocardiogram (ECG), clinical laboratory evaluations, at Screening and prior to administration of the initial dose of study drug;  Must be able and willing to comply with all study requirements including:  Confinement to the CRU prior to and during study drug administration and required follow-up periods for Part A SAD and Part B MAD Refraining from using the following:  i. Any previous/current cannabis products within 2 months prior to Screening and throughout the duration of the study (from the time of Screening until the EOS visit); ii. Cannabis products (in the form of oil, vaporizer, or smoke) for the duration of the study; iii. Prescription medications 14 days prior to administration of the first dose of study drug; iv. Alcohol 48 hours prior to admission, and while confined to the CRU. In addition, participants must agree to refrain from regular use of alcohol (i.e. ˃ 10 units per week or ˃ 4 units on any given day for men and women [1 unit = 150mL of wine, 360 mL of beer, or 45 mL of 40% alcohol]) for the duration of the study; v. Recreational drugs for the duration of the study.  For Part A SAD, participants must not have used cannabis or cannabinoid products within 2 months prior to Screening.
