The meta-analysis also looked at the impact of medicinal cannabinoids on Tourette’s syndrome, post-traumatic stress disorder and psychosis.
Research which combined 83 studies involving 3,000 people suggested their use for the six mental health conditions cannot be justified based on the current evidence.
Scientists said this is due to a lack of evidence for their effectiveness, and because of the known risks of cannabinoids.
But the study, published in the Lancet Psychiatry journal, suggests there is very low quality evidence that pharmaceutical tetrahydrocannabinol (THC) may lead to a small improvement in symptoms of anxiety in individuals with other medical conditions.
