Brief summary

This trial will investigate the single dose pharmacokinetics of two sublingually administered cannabis products, one CBD dominant the other THC dominant. This data will be used to inform dosing decisions in other trials. A secondary objective of this trial is to identify at what point do subjects begin to feel the intoxicating effects of these products and for how long they last.

Interventions

Cohort 1: Single dose sublingually 2ml administration of a cannabis tincture containing 50mg Cannabidiol (CBD) and 1.9mg delta-9-Tetrahydrocannabinol (THC) per ml in solution with MCT oil. Participants must hold the tincture under their tongue for 60 seconds before swallowing. Cohort 2: Single dose sublingually 2ml administration of a cannabis tincture containing 0mg CBD and 2.5mg THC per ml in solution with MCT oil. Participants must hold the tincture under their tongue for 60 seconds before
