A Study of Ingested Cannabidiol in Healthy Occasional Cannabis Users

The purposes of this study are 1) to determine if the administration of different low doses of oral CBD (20 mg, 50 mg, 100 mg and 200 mg) result in detectable subjective pleasant drug effect compared to placebo and 2) to qualitatively explore whether low dose of oral CBD is associated with effects that are not detected with the available research tools.
