The long-term goal of the project is to determine whether cannabidiol (CBD) can reduce craving and relapse in individuals with opioid use disorder (OUD). The first phase of our project was an open cross-over design study in healthy individuals to confirm the safety and pharmacokinetic (PK) effects of CBD. This next phase is to determine whether CBD can serve as a potential adjunct treatment to reduce craving and anxiety in individuals with OUD maintained on opioid agonist therapy.
In this Phase 2 study, the research team will conduct a double-blind (placebo-controlled) randomized controlled trial to evaluate whether 200mg and/or 400mg CBD (BSPG Laboratories) given twice daily (morning and evening), as compared to placebo, reduces cue-induced craving and anxiety in individuals with opioid use disorder who are maintained on methadone or buprenorphine. In addition to in-lab physiological and behavioral assessments of cue-induced craving and anxiety, the research team will also employ ecological momentary assessment to obtain real-world measures of symptoms including craving, anxiety, and mood.

Change in Visual Analog Scale for Craving (VASC)
Cue-induced Visual Analog Scale for craving is used to measure subjective craving responses to a drug and neutral video cues evaluated in the clinic. Changes in craving from baseline (pre-cue to post-cue and pre-neutral cue to post-neutral cue) will be measured and compared. Total scale ranges from 0-10, with higher scores indicating extreme cravings.
Time frame: Baseline and 4 weeks
Change in Visual Analog Scale Anxiety (VASA)
Cue-induced Visual Analog Scale Anxiety is used to measure subjective anxiety responses to a drug and neutral video cue evaluated in the clinic. Changes in anxiety from baseline (pre-cue to post-cue and pre-neutral cue to post-neutral cue) will be measured and compared. Total scale from 0-10, with higher score indicating extreme anxiety.
Time frame: Baseline and 4-weeks

Systematic Assessment for Treatment Emergent Events (SAFTEE)
Systematic Assessment for Treatment Emergent Events (SAFTEE) is used to measure safety and tolerability. SAFTEE is a side effect self-report assessment scale that consists of 56 potential side effects. Participants rate how bothersome each side effect is on a scale of "none" (0), "mild" (1), "moderate" (2), "severe" (3). Total score ranges 0 - 168, higher scores indicate a higher level of side effect burden.
Time frame: weekly for 8 weeks (Baseline, Week 1, 2, 3, 4, 5, 6, 7, and 8)
Change in Visual Analog Scale for Craving (VASC)
Cue-induced Visual Analog Scale for craving is used to measure subjective craving responses to a drug and neutral video cues evaluated in the clinic. Changes in craving at 8 weeks as compared to 4 weeks (pre-cue to post-cue and pre-neutral cue to post-neutral cue) will be measured and compared. Scale range: 0 (no craving) - 10 (extreme craving). Higher score indicates more extreme craving.

Time frame: 4-weeks and 8-weeks
Change in Visual Analog Scale Anxiety (VASA)
Cue-induced Visual Analog Scale Anxiety is used to measure subjective anxiety responses to a drug and neutral video cue evaluated in the clinic. Changes in anxiety at 8 weeks as compared to 4 weeks (pre-cue to post-cue and pre-neutral cue to post-neutral cue) will be measured and compared. Scale: 0 (not at all anxious) - 10 (extremely anxious). Higher score indicates more extreme anxiety.
Time frame: 4-weeks and 8-weeks
Change in Percentage of Participants With Positive Urine Toxicology
Proportion of percentage with positive urine toxicology for illicit opioid use at 8 weeks as compared to 4 weeks.

Change in Heroin Craving Questionnaire Short Form (HCQ-SF-14)
Heroin Craving Questionnaire Short Form (HCQ-SF-14): A 15 minute, 14 item self-administered to measure general heroin craving. Each item is rated on a 7-point Likert scale (1= strongly disagree, 7= strongly agree). Full scale ranges from 14-98, with higher scores indicating more severe heroin craving.
Time frame: baseline and 4-weeks, 4-weeks and 8-weeks
Change in Generalized Anxiety Disorder Scale (GAD-7)
The General Anxiety Disorder 7-item questionnaire (GAD-7) assesses seven problem items potentially experienced over the past two weeks from "0" (not at all) to "3" (nearly every day). Individuals rank their levels of nervousness, anxiousness, relaxing, restlessness, irritability and fearfulness. Full scale from 0-21, with higher score indicating more anxiety symptoms.
Time frame: Baseline and 4-weeks, 4-weeks and 8-weeks
Duration of Participant First Illicit Opioid Abstinence
Time frame: any time during study, 8 weeks
Change in Patient Health Questionnaire (PHQ-9)
The Questionnaire Type 9 for Depression (PHQ-9) measures depression severity with the nine DSM-IV criteria scored as "0" (not at all) to "3" (nearly every day). Full scale ranges from 0-27, with higher score indicating more severe symptoms.
Time frame: baseline and 4-weeks, 4-weeks and 8-weeks
Positive and Negative Affect Schedule (PANAS-SF)
A 20 item self-administered questionnaire evaluating current positive and negative affect. Each item is rated on a 5-point scale (0= Very slightly or not at all, 5= Extremely).
