Research and Medical Marijuana
Ancient Chinese and Persian medical texts suggest that cannabis is useful for treating seizures. Evidence from laboratory studies, anecdotal reports, and small clinical studies from a number of years ago suggest that cannabidiol, a non-psychoactive compound of cannabis, could potentially be helpful in controlling seizures.
Research has been limited, but a new study of cannabidiol has given some credence to these claims. Children with a severe form of epilepsy had 39 percent fewer seizures per month after taking CBD. Three people stopped having seizures altogether.
