OTHER_PRE_SPECIFIED outcome
Timeframe: 6 hoursPopulation: 8 participants volunteered to come to a ninth session for dosing with 800 mg CBD and donation of 7 blood samples.
Plasma concentrations of cannabidiol were measured at six time points after oral administration of four 200 mg capsules of CBD.
