The Utah agency has since given out 84 cards, which cost $200.
Isabelle was "virtually stoned on medications" before trying the oil, said her mother, Syndi Knowlton. "You looked at her and there was no life in her eyes." Now, the girl with two rare genetic disorders is bright-eyed and giggly.
Isabelle, who takes her nightly dose in a pea-size dollop of coconut oil, has not seized since the first dose, her mother said.
"She's a totally different child," Knowlton said.
A 2014 Utah law established the permit program. The change in state statute drew cheers from families who shared stories of epileptic children to overcome lawmakers' suspicions about medical marijuana.
To qualify for a card, an epilepsy patient must have exhausted traditional therapies. The permit requires a neurologist's certification and a physician's evaluation.
The 2014 law allows permit holders and their families to legally possess oil that is at least 15 percent cannabidiol — the chemical in cannabis believed to have anti-seizure properties.
But to legally enter Utah, the oil must contain less than 0.3 percent of tetrahydrocannabinol, or THC — the chemical that gives marijuana users a high. That threshold is so low that the product qualifies as agricultural.
Rep. Gage Froerer, the Huntsville Republican who sponsored the measure, plans to bring another proposal next year to extend the program. He believes lawmakers will back his initiative to scrub the July 2016 expiration date.
"We've got enough facts and data now," Froerer said, "to show there's no need to have a sunset provision in it."
Fifteen states have similar laws regarding cannabidiol (CBD). A total of 22 states, plus the District of Columbia, allow the use of medical marijuana.
The product is still illegal under federal law. But federal officials have urged U.S. prosecutors to avoid filing charges against medical marijuana distributors — so long as they abide by state laws.
Annette Maughan received one of the first permits issued last year, allowing her to legally import cannabis oil for her 12-year-old son, Glenn. Since he started the treatment, his daily seizures, which began at age 3, now come up to a week apart — about half as often as they used to, Maughan said.
