The purpose of this study is to test a new formulation of cannabidiol (CBD) to see how it is processed in the body and how safe it is for healthy volunteers. CBD is a compound found in the cannabis plant that has shown potential to help treat various medical and mental health conditions. While there is already an approved CBD-based drug that is used for epilepsy in the UK, called Epidyolex, most CBD formulations have poor absorption when taken orally, reducing their effectiveness and often requiring higher doses. NW PharmaTech has developed a new CBD formulation aimed at improving absorption and processing by the body. This study will assess the absorption, safety, and tolerability of two different doses (600 mg and 900 mg) of the new formulation and will compare them with Epidyolex (dosed as per approved label). All participants will receive each of the following three dosing regimens in a randomised order across three separate experimental periods, with each period separated by a 25 day washout period, which ensures that the drug from one dosing regimen is fully cleared from your body before the next dosing regimen begins. Regimen A: 600 mg of the new CBD formulation (NW300EMCBD) administered orally Regimen B: 900 mg of the new CBD formulation (NW300EMCBD) administered orally Regimen C: 25 mg/kg Epidyolex solution (2 x 12.5 mg/kg doses separated by 12 hours) administered orally In total, participants will complete three dosing visits (one per experimental period), each spaced 25 days apart. The study will evaluate the pharmacokinetics (PK) of the formulations, which refers to how the body absorbs, distributes, metabolizes, and eliminates the drugs.

The GSRS is a 15-item rating scale, where each item is assessed with a 7-point Likert scale, with higher scores indicating more severe symptoms.

The Columbia-Suicide Severity Rating Scale (C-SSRS) is a clinician administered assessment tool that evaluates suicidal ideation and behavior. Number of participants that have an affirmative response provided to the 5 items for suicidal ideation (1. Wish to be dead, 2. Non-specific active suicidal thoughts, 3. Active suicidal ideation with any methods (not plan) without intent to act, 4. Active suicidal ideation with some intent to act, without specific plan, 5. Active suicidal ideation with specific plan and intent) and/or to the 6 items for suicidal behavior (1. Actual attempt, 2. Interrupted attempt, 3. Aborted attempt, 4. Preparatory acts or behavior, 5. Suicidal Behavior 6. Completed suicide,) will be reported.

Time frame: Pre-dose to 3 hours post dose
The Visual Analog Mood Scale (VAMS) measures subjective mood states. Participants mark their feelings on a 100-mm line, scored from 0 (not at all) to 100 (extremely). For the subscales (Mental Sedation, Tranquilization and Calming Effects, Physical Sedation, Other Feelings and Effects), higher scores indicate greater intensity of the measured effect.
Time frame: Pre-dose to 3 hours post dose
The DEQ-5 is a brief self-report measure designed to assess acute subjective experiences of drug effects. It comprises five items in which participants rate their current experiences of drug effect, feeling "high," liking the drug effects, disliking the drug effects, and wanting more of the substance. Responses are recorded using 100-mm visual analog scales, scored from 0 (not at all) to 100 (extremely). Higher scores indicate greater intensity of the subjective experience being measured.
