Cannabidiol corrects sleep deficits and reduces spontaneous seizures in Angelman syndrome model mice

The off-label use of cannabidiol (CBD) has outpaced investigation. We assessed the effects of CBD in Angelman syndrome model mice lacking the Ube3a gene and found that chronic injection of CBD increased rapid-eye movement sleep during the dark cycle, restored "Siesta", improved sleep homeostasis, and reduced spontaneous seizures following flurothyl kindling.
