Charlotte's father found a video online of a California boy whose Dravet was being successfully treated with cannabis. The strain was low in tetrahydrocannabinol, or THC, the compound in marijuana that's psychoactive. It was also high in cannabidiol, or CBD, which has medicinal properties but no psychoactivity. Scientists think the CBD quiets the excessive electrical and chemical activity in the brain that causes seizures. It had worked for this boy, his parents saw a major reduction in the boy's seizures. Maybe it could work for Charlotte, who by this time had lost the ability to walk, talk and eat. - CNN
