The initial goal is to ascertain the pharmacokinetic (PK) profile of CBD (cannabidiol) after a single dose of CBDE (cannabidiol extract), although the plan is to extend these studies to multiple dose administrations in the future, since it is likely that (cannabidiol) and/or its metabolites will show some accumulation. These studies will provide detailed information that will inform the continuation and expansion of CBDE in other research projects.
The objective is to determine the PK profile of CBD(cannabidiol) , its metabolites, and minor phytocannabinoids after single dose administration of CBDE (at 2.5 mg/kg CBD). Attainment of this goal will provide essential information on phytocannabinoid disposition and dosing regimen optimization. To accomplish this objective, the working hypothesis that complex phytochemical mixtures present in full spectrum hemp extracts (FSHEs), as exemplified by CBDE, differ from purified CBD-containing products with regard to PK, will be tested. The approach to testing this working hypothesis will be to use liquid chromatography-mass spectrometry (LC/MS) to both characterize the phytocannabinoid concentration-time profiles following CBDE administration (single and multiple dosing).

| Cannabidiol extract | Experimental | 10 healthy subjects (5 female, 5 male), will be enrolled into the study. Each subject will receive a single CBDE dose delivering 2.5 mg/kg CBD, after consumption of a standardized meal. Nine (9mL) of blood for PK analysis, at each of the following timepoints: 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours, 24 hours, 36 hours, 48 hours and 72 hours after the study drug administration. Urine will be collected at the following timepoints: Predose, 0-4 hrs, 4-8 hrs, 8-12 hrs, 12-24 hrs, 24-36 hrs, 36-48 hrs, and 48-72 hrs for PK analysis |

This study is a single center, prospective, Phase I PK trial. A total of 10 healthy subjects will be enrolled into the study. This study will evaluate the pharmacokinetics of CBDE.
The PK of CBD, 9-tetrahydrocannabinol (THC) and their principal metabolites will be determined after a single CBDE dose delivering 2.5 mg/kg CBD. ). CBDE will be provided in liquid concentration of 50mg/ml in sesame seed oil (SSO).
