Brief summary
Cannabidiol (CBD), a non-psychoactive hemp derivative, is an attractive therapeutic agent, and is most supported by the scientific community as an antiepileptic. Additionally, CBD is also associated with claims related to improvements in overall health, pain, anxiety, depression, and sleep; however, the scientific evidence is lacking. The overarching goal of this investigation is to determine the effects of a 4-week CBD intervention on measures of overall health, pain, anxiety, depression, and sleep in a population of US veterans. Primary aims will explore the effects of 4 weeks of CBD on pain, anxiety, and depression. Secondary aims will determine whether 4 weeks of CBD will affect general measures of overall health and sleep.
Detailed description
In this double-blind investigation, participants will undergo 6 online assessments. Two assessments (assessments 1 and 2) will take place before the intervention period and assessments 3-6 will be conducted at the end of every week during the intervention period (assessment 3 at the end of week one, assessment 4 at the end of week 2, assessment 5 at the end of week 3 and assessment 6 at the end of week 4). After participants (N=100) reach out to inquire about the study, they will be provided with an informed consent, and they will be asked to obtain physician approval to participate in the study. Once this approval is obtained, they will be randomized into either a cannabidiol ingesting group (CG, n=50, 50 mg of CBD per day)) or a placebo-controlled group (PC, n=50, 0 mg of CBD per day). Then, they will be sent a link to a survey which includes questions evaluating overall health, anxiety, depression, pain and sleep. The details of these surveys are outlined below. Once researchers receive a completed assessment 1, the participants will be mailed packages containing bottles of either CBD or a placebo capsules (32 capsules provided in each bottle). One week after assessment 1, participants will complete assessment 2 and will begin to take one capsule per day in the evening after their last meal. Participants will take the same online surveys in all assessments with the exception of the initial informed consent (in visit one only) as well as a few open-ended study experience questions in assessment 6. During the intervention period, all participants will complete capsule logs in which they confirm that they have consumed one of their assigned capsules each day. Subjects will take a picture and email the log back to researchers at the end of the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of Veterans RAND 12 Item Health Survey single domains | Twice, separated by 1 week, prior to the start of the intervention and weekly during the 4 week intervention | Veterans Health Survey RAND (VR-12). Two z scores are reported (Mental Component and Physical Component Scores)patient self-report, 12 questions, minimum value: 12 points, maximum value: 54 points, physical and mental health component summary score compared to a t-score with a mean value of 50 and standard deviation of 10 |
| Change in General Anxiety Disorder Questionnaire Score | Twice, separated by 1 week, prior to the start of the intervention and weekly during the 4 week intervention | General Anxiety Disorder Questionnaire 7.The GAD-7 scale score ranges from 0 to 21 points. A higher score suggests higher levels of anxiety. |
| Change in Beck Depression Inventory Score | Twice, separated by 1 week, prior to the start of the intervention and weekly during the 4 week intervention | Beck Depression Inventory (BDI). Highest score is 63, Lowest score is 0.The higher the score, the more presence of depression. |
| Change in Defense and Veterans Pain Rating Scale Score | Twice, separated by 1 week, prior to the start of the intervention and weekly during the 4 week intervention | Defense and Veterans Pain Rating Scale. Each item is scored 0 (no pain) - 10 (pain as bad as it can be). The higher the score indicates higher levels of pain. |
| Change in Pittsburg Sleep Quality Index Score | Twice, separated by 1 week, prior to the start of the intervention and weekly during the 4 week intervention | Pittsburg Sleep Quality Index. Scores for each question range from 0-3. Higher scores indicating lower sleep quality. |
