(CNN)Doctors in Macon, Georgia, told Janea Cox that her daughter, Haleigh, might not live another three months. That was the middle of March, when Haleigh's brain was being short-circuited by hundreds of seizures a day, overrunning the array of five potent drugs meant to control them. Worse, the drugs were damaging Haleigh's organs. "She was maxed out," Cox said. "She'd quit breathing several times a day, and the doctors blamed it on the seizure medications." Cox had heard that a form of medical marijuana might help, but it wasn't available in central Georgia. So a week after hearing the ominous diagnosis, she and Haleigh packed up and moved to Colorado Springs, Colorado. There, Haleigh began a regimen of cannabis oil: four times a day and once at night.
