Families with Seizure-Prone Kids Relocating to Colo. for Pot Access

Though doctors warn the treatment is still unproven

COLORADO SPRINGS, Colo. -- Parents are flocking to Colorado with their sick children to find "Charlotte's Web," a strain of marijuana thought to treat debilitating seizure disorders.

The strain was named for 5-year-old Charlotte Figi, who had been suffering from a rare disorder called Dravet's syndrome, which caused her to have as many as 300 grand mal seizures a week.

Charlotte used a wheelchair, went into repeated cardiac arrest and could barely speak, but doctors were out of ideas for help. Then as a last resort, her mother began calling medical marijuana shops.

Two years later, Charlotte is largely seizure-free and able to walk, talk and feed herself after taking oil infused with a special pot strain. Her recovery inspired the Charlotte's Web name for the marijuana strain she takes in oil form that is bred not to have THC -- the ingredient that make users high.
