Los Angeles, CA (KTLA) -- After trying multiple medications, cannabis oil was the only medication to help a 2-year-old with epilepsy, according to his mother.
"What nine other medications couldn't do, this is what controlled him, what is controlling him," Genesis Rios said of her son.
Rios' son had almost constant seizures before using cannabis oil, Rios said.
She began giving her son the oil four months ago by putting a few drops under his tongue three times a day.
The oil is high in a compound that slows the brain activity that triggers seizures, but low in THC, the compound that provides a typical pot high.
"There is no THC in it basically," Rios said.
The family made the decision in the face of dramatic failure, chief of pediatric neurology at Mattel Children's Hospital Raman Sankar said.
"I'm not endorsing it yet because I need the data, but I cannot hold it against somebody for trying something," Sankar said.
The boy had no side-effects from the cannabis oil and had begun walking more, interacting and trying to talk, Rios said.
"I really, really want more research into this, because now I have my son back," Rios said.
