Several clinical trials have tested the therapeutic potential of cannabinoids after Stroke. Meta-analysis revealed that both endocannabinoids like AEA, OEA or PEA and plant cannabinoids like THC or CBD can significantly reduce neuronal degeneration after Stroke (England et al., 2015). Specifically activating CB1 and/or CB2 receptors had the strongest protective effect but other receptors such as 5-HT1a and PPARα are also likely to be involved.
