Laboratory results outside of the reference range, but acceptable, must be documented as not clinically significant (NCS) at the discretion of the investigator.
3. Subjects must have a body mass index between 18-30.4 kg/m2, inclusive.
4. Females of childbearing potential must have a negative pregnancy test at Screening and a negative pregnancy test on Day -1 at admission to the CRU. If females are of non-child bearing potential, they must be post-menopausal defined as: age > 55 with no menses within the past 12 months and with a follicle stimulating hormone (FSH) level > 40 IU/L or history of hysterectomy, or history of bilateral oophorectomy, or bilateral tubal ligation.
5. Males must consent to use a condom throughout the entire study period and for 90 days after their last study drug application. They must agree to not donate sperm for 90 days after their last study drug application.
6. Subject must agree to abide by all study restrictions and comply with all protocol requirements and study procedures.
1. Females who are pregnant, nursing or planning a pregnancy; females of childbearing potential, and male subjects with a partner of childbearing potential, who are unwilling or unable to use an acceptable method of contraception as outlined in this protocol from at least 21 days prior to the first dose of study medication and for 30 days after the last dose of study medication.
a. Standard acceptable methods include: males to use a condom, female participants and female partners of male participants who are women of child bearing potential to use an actual highly effective method of contraception (i.e. hormonal method with a <1% annual failure rate or an IUD), abstinence, and vasectomy.
2. Has eaten any food or drink/beverage containing alcohol, grapefruit or grapefruit juice, apple or orange juice, vegetables from the mustard family (e.g., kale, broccoli, watercress, collard greens, kohlrabi, Brussel sprouts, or mustard), and charbroiled meats within one week prior to study start through the end of the study.

5. Use of cannabis or any CBD-containing product within four weeks of the Screening Visit or during the study.
6. Positive result for the presence of Hepatitis B surface antigen (HBsAg), Hepatitis C virus antibodies (HCV-Ab), or human immunodeficiency virus (HIV) antibodies.
7. Positive drug screen for ethanol, cocaine, delta-9-tetrahydrocannabinol (THC), barbiturates, amphetamines, benzodiazepines, and opiates at Screening and Day -1.
8. Any clinically significant condition or abnormal findings at the Screening Visit that would, in the opinion of the investigator, preclude study participation or interfere with the evaluation of the study treatment.
9. Any skin disease or condition, including eczema, psoriasis, melanoma, acne or contact dermatitis, scarring, imperfections, lesions, tattoos or discoloration that may affect treatment application, application site assessments, or affect absorption of the study drug.
10. Use of cosmetics (excluding study moisturizer) on the shoulder/upper arms or upper thighs, during the study period.
11. History of significant allergic condition, significant drug-related hypersensitivity, or allergic reaction to any adhesives, compound, or chemical class related to ZYN002 or its excipients.
12. History of treatment for, or evidence of alcohol or drug abuse within the past year or current alcohol consumption exceeding an average of two units of alcohol per day.
13. History or current diagnosis of a significant psychiatric disorder that would, in the opinion of the investigator, affect the subject’s ability to comply with the study requirements.
14. Has suspected or confirmed cardiovascular disease.
15. Participation in any investigational product or device study within 30 days prior to Screening Visit, or is scheduled to participate in an investigational device or another investigational drug study during the course of this study.

- Primary Outcome Measures
Name Time Method Primary Outcome 1: The primary objective of this study is to evaluate the relative bioavailability of ZYN002 (CBD) gel applied to the skin of the upper arms/shoulders (test) compared to the upper arms/shoulders and upper thighs (reference) following single and multiple dosing. The same amount of CBD will be applied although the amount of gel applied and the surface area of application will vary as well as the site of application. <br>Assessed by: collecting blood samples for analysis. PK parameters include: Cmax, Tmax, AUC.<br>[Timepoint: Blood samples collected on Day 1 pre-dose and 0.5, 1, 2, 3, 4, 6, 8, 10, and 12 hours post-dose; on Days 8, 10 and 12 pre-dose; on Day 14 pre-dose and 0.5, 1, 2, 3, 4, 6, 8, 10, and 12 hours post-dose; Day 20 at follow-up.]
- Secondary Outcome Measures
Name Time Method Secondary Outcome 1: The secondary objective of this study is to evaluate the safety and tolerability of a ZYN002 7.5% CBD concentration (first in man) vs the 4.2% concentration of CBD following repeated application to healthy adult male and female subjects. <br>Assessed by: monitoring physical examinations, examination of skin application site, vital signs, 12-lead ECG, laboratory tests, the Columbia Suicide Severity Rating Scale (C-SSRS) testing and adverse events throughout the study. Possible adverse events could include- appetite change, diarrhoea, fatigue, tiredness, drowsiness, application site skin reactions (e.g. dryness, itching, inflammation, tingling or pain).<br>[Timepoint: Daily examination and monitoring for up to and including 20 days after initial treatment dose.]
