Brief Summary
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.

Pleasant drug effect will be assessed using a single item, visual analog scale, administered following administration of the study product at each study visit. It is rated on a continuous scale ranging from 0 (not at all) to 100 (extremely).
T2 (120 minutes after ingestion)
Pleasant drug effect
Pleasant drug effect will be assessed using a single item, visual analog scale, administered following administration of the study product at each study visit. It is rated on a continuous scale ranging from 0 (not at all) to 100 (extremely).
T3 (210 minutes after ingestion)
Pleasant drug effect
Pleasant drug effect will be assessed using a single item, visual analog scale, administered following administration of the study product at each study visit. It is rated on a continuous scale ranging from 0 (not at all) to 100 (extremely).
T4 (300 minutes after ingestion)
Pleasant drug effect
Pleasant drug effect will be assessed using a single item, visual analog scale, administered following administration of the study product at each study visit. It is rated on a continuous scale ranging from 0 (not at all) to 100 (extremely).

Study Arms (5)
0 mg CBD, ingested placebo
EXPERIMENTALIngested placebo containing 0 mg CBD. Group will attend a total of five study visits (one for each study product) with at least 1 week between each visit. The order in which the study products will be administered depend on the randomization sequence.
20 mg CBD, ingested CBD
EXPERIMENTALIngested cannabis containing 20 mg CBD. Group will attend a total of five study visits (one for each study product) with at least 1 week between each visit. The order in which the study products will be administered depend on the randomization sequence.
50 mg CBD, ingested CBD
EXPERIMENTALIngested cannabis containing 50 mg CBD. Group will attend a total of five study visits (one for each study product) with at least 1 week between each visit. The order in which the study products will be administered depend on the randomization sequence.
100 mg CBD, ingested CBD
EXPERIMENTALIngested cannabis containing 100 mg CBD. Group will attend a total of five study visits (one for each study product) with at least 1 week between each visit. The order in which the study products will be administered depend on the randomization sequence.
200 mg CBD, ingested CBD
EXPERIMENTALIngested cannabis containing 200 mg CBD Group will attend a total of five study visits (one for each study product) with at least 1 week between each visit. The order in which the study products will be administered depend on the randomization sequence.
Interventions
Eligible participant will be randomize 1:1:1:1:1 to receive study products in a prefilled single syringe with 2 ml of product solution with varying amounts of CBD (0 - 20 mg - 50 mg -100 mg - 200 mg. Only one research product will be ingested at each visit. The sequence will depend on the assigned randomization group.
