Brief Summary:
The purpose of this double-blind, placebo-controlled study is to determine the analgesic effects of cannabidiol (CBD), a chemical constituent found in cannabis that does not have intoxicating effects. The analgesic effects of CBD will be assessed using the Cold-Pressor Test (CPT), a laboratory model of pain which has predictive validity for the clinical use of analgesics.

Condition or disease Intervention/treatment Phase
Pain Drug: Cannabidiol Drug: Placebo Phase 1 Phase 2

Detailed Description:
This within-subject, double-blind, placebo-controlled study will assess the analgesic and subjective effects of a range of CBD doses (0, 200, 400, or 800 mg, po). Volunteers will participate in 4 outpatient laboratory sessions over the course of 4 weeks during which the analgesic effects of CBD will be assessed using the Cold-Pressor Test (CPT), a laboratory model of pain which has predictive validity for the clinical use of analgesics. The order of CBD dose will be randomized across participants. Secondary measures will include subjective and physiologic effects of CBD.

Actual Enrollment : 18 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Basic Science
Official Title: Characterization of the Analgesic Effects of Oral CBD in Healthy, Normal Volunteers
Study Start Date : June 2016
Estimated Primary Completion Date : December 2021
Estimated Study Completion Date : December 2021

Arm Intervention/treatment
Active Comparator: Active CBD
Each subject will receive each active dose of cannabidiol, one active dose per 3 of the 4 study days. The active cannabidiol doses include 200, 400 and 800 mg of cannabidiol.
Drug: Cannabidiol
200, 400, or 800 mg Cannabidiol
Other Name: CBD

Placebo Comparator: Placebo
On 1 of the 4 study days, participants will receive placebo cannabidiol (0 mg)
Drug: Placebo
0 mg Cannabidiol

Primary Outcome Measures :
  1. Analgesia: Pain tolerance and threshold as measured by the Cold Pressor Test [ Time Frame: 10 minutes ]
    Time to first feel pain ("Pain threshold" measured in seconds) during the Cold Pressor Test and withdraw the hand from the cold water ("Pain Tolerance" measured in seconds)

Secondary Outcome Measures :
  1. Subjective drug effects related to abuse liability as measured by visual analog scales [ Time Frame: 2 minutes ]
    Participants rate the strength of the drug effect, drug liking, desire to take again, good effect and bad effect. Each item will be presented and the participant will be asked to rate his / her rating on a scale anchored by 'Not At All' (0 mm) to 'Extremely' (100 mm).
