It was the day Michael Lambert watched his infant daughter suffer a violent two-and-a-half-hour seizure that he says he decided breaking the law was a small price to pay for her life.
Katelyn had been diagnosed with a severe form of epilepsy known as Dravet Syndrome and her family was told there was a one-in-six chance she would be dead before she turned 18.
“They told me, ‘Go out and have as much fun as you can with this child now, just forget she’s got epilepsy, because you don’t know how long you’ll have with her’,” Mr Lambert said.
At just 11 months old, Katelyn could have seizures every 15-20 seconds and for hours on end.
Now seven, she averages one a year.
Her father said he believed this was because he had been giving her five drops of illegal cannabis oil every day for nearly five years.
Katelyn’s paediatrician and neurologist admitted she had shown dramatic improvements.
