Cannabidiol Effect on Anxiety Symptoms and Stress Response in Individuals With Cocaine Use Disorder: Exploratory Results From a Randomized Controlled Trial
Abstract
Objectives Individuals with a cocaine use disorder (CUD) are more likely to present anxiety, which in turn negatively impacts substance use outcomes. Some evidence suggests that cannabidiol (CBD) presents anxiolytic properties and could be a treatment for substance use disorders. This study explores CBD’s effect on stress biomarker (cortisol) and anxiety symptoms in people with CUD. Methods Exploratory analyses were conducted using data from a randomized, double-blind, placebo-controlled trial evaluating CBD’s efficacy to treat CUD. We randomized 78 individuals with CUD into receiving a daily oral dose up to 800 mg CBD (n = 40) or placebo (n = 38). The trial was divided into 2 phases: an inpatient detoxification lasting 10 days and an outpatient follow-up lasting 12 weeks. Anxiety symptoms and stress response were assessed using a visual analog scale, the Beck Anxiety Inventory, and cortisol levels at multiple time points throughout the study. We also measured anxiety after a stressful and a cocaine-cue scenarios. We used generalized estimating equations models and multiple linear regression to assess CBD’s effects on anxiety and cortisol levels. Results Both treatment groups had similar mean anxiety scores according to the Beck Anxiety Inventory (P = 0.27) and the visual analog scale (P = 0.18). CBD did not decrease anxiety after a stressful (P = 0.14) and a cocaine (P = 0.885) scenarios compared with placebo. No statistically significant group difference was found in…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 78 participants or records.
