Mental Cannabis Health and
Amongst the studies in psychiatric populations, two studies involved patients with social anxiety disorder SAD. Both studies investigated the effects of CBD on self-reported anxiety levels.
In both, the CBD group reported less anxiety than placebo as well as healthy controls if used. However, the review authors did not report the magnitude of the effect and only one study featured a task designed to elicit anxiety. The other was a neuroimaging study and relied on the MRI scanner to induce anxiety. Two observational studies were identified, one published and one unpublished, for plant-based cannabis for PTSD.
By the end of the observational period 2 years and However, none featured a comparison group not receiving cannabinoids and none, therefore, were randomised. One other study was identified of Nabilone that used a cross-sectional design that also found a benefit. The review authors also report on case reports of plant-based cannabis and Dronabinol, but the quality of evidence was extremely low.
Overall, the standard of evidence is currently extremely poor. Not when it comes to medical research. BUT, these studies are small, often without a control group, and are therefore likely to be at high risk of bias. This review found some evidence that cannabis or cannabinoids may be beneficial for anxiety, mood, and other related disorders. However, the overall quality of the evidence was poor and extremely limited.
Few studies have looked at psychiatric populations, and most of these were very small, while only observational studies had larger sample sizes. Many trials featured only an experimental group and no comparison, and most had other deficiencies such as using a single dose of the treatment or a short follow-up period that may not allow potentially adverse side-effects to be identified.
Secondly, some of the better designed studies in this review investigated healthy participants rather than patients.
While these studies suggest that some cannabinoids may have an anxiolytic effect, this does not mean participants with anxiety disorders will really experience much benefit from using them. They also do not give an assessment of the overall quality of the evidences or an evaluation of the risk of bias. The effect sizes in individual studies are often not reported, and there are no meta-analyses of overall treatment effects.
