Charlotte Figi, the 13-year-old girl with epilepsy who helped ignite a medical-cannabis movement, has died from complications suspected to be coronavirus related, according to a Tuesday Facebook announcement. She would be the youngest Colorado resident to die from COVID-19 if officials confirm the cause, The Colorado Sun reported.

On her Facebook page, Charlotte’s mother, Paige Figi, wrote that despite a previous negative coronavirus test, her daughter was “treated as a likely COVID-19 case.”

Charlotte Figi, her parents, and the Stanley brothers, who own a Colorado Springs medical-marijuana dispensary, worked together to create a cannabis strain that contained a high concentration of CBD, a nonpsychoactive compound found in cannabis, and a low concentration of the psychoactive component THC.

Figi successfully used this strain, dubbed Charlotte’s Web, to treat her seizures, and soon other people with chronic conditions learned of her story and sought CBD treatments themselves.

“She was a light that lit the world. She was a little girl who carried us all on her small shoulders,” the Stanley brothers wrote in a tribute on the Charlotte’s Web website. “She grew, cultivated by a community, protected by love, demanding that the world witness her suffering so that they might find a solution. She rose every day, awakening others with her courage, and with that smile that infected your spirit at the cellular level.”

In the week’s prior, Figi’s mother said her entire family was feeling ill but that they were unable to get coronavirus tests.

Charlotte had Dravet syndrome, a type of epilepsy, and from the time she was 3 months old, she experienced hundreds of seizures every day, according to the newspaper.
