Well I may be wrong, but a documentary was done on CNN by Dr. Gupta on pot and stopping severe seizure disorder and some other chronic illnesses. They found that strain was low in THC and high in CBD which has medicinal properties, but no psycoactivity. scientist believe the CBD quiets the excessive electrical and chemical activity in the brain that cause seizures and etc....One very young girl couldn't even walk etc.... She takes it liquid in her food. There is only one dispensary in Colorado I believe it is and they only ask for donation.
You can read or watch the documentary just Google it, for some reason it won't let me copy and paste lately I don't know why???? It's called weed and featured on CNN.
