Jason David is the father of a six-year-old boy with Dravet Syndrome, a rare and catastrophic form of epilepsy that begins in infancy.
It all started when he saw his son, Jayden, at four months old have a seizure.
"Seeing your four-month-old son have a seizure on Christmas morning was the worst day of my life," he said.
After trying over 20 anti-psychotic medications and seeing no change, Jason made the decision to try a form of medical marijuana -- known as CBD -- which does not get a person high because it doesn't contain THC.
He said the marijuana alleviated the pain -- and hasn't seen any negative side effects.
The law, however, isn't so kind. Federal law bans the use of medical marijuana even though several states, including California, have legalized it.
Now his mission is clear: Advocacy.
"I'm not a marijuana advocate; I'm an advocate for children without a voice ... I want help for all disabled kids and parents to have options not just to use this in California but across the country and across the world. Why not have an option to save our childrens' lives?"
