For a little over a year, Lora and Roger Barbour have been giving their 16-year-old daughter, Genny, medical marijuana oil four times a day to treat her seizures. Genny, who has epilepsy and autism, has been able to live much more comfortably after being administered carefully measured doses of THC, according to her parents.

"She blossomed into a child who, the other day, she walked into my office and said, 'I love you,'" Roger told People. "My wife and I looked at each other, and both started crying."

After unsuccessfully cycling through several pharmaceutical options, Genny's parents were thrilled to see their daughter flourishing, becoming calmer and more talkative. But there was still the persistent problem with Genny's ability to use medical marijuana at her school in New Jersey. According to People, "though medical marijuana is legal in the state of New Jersey, the state law is silent on its use in schools; the Maple Shade School District says it's illegal for them to administer it because marijuana is still illegal under federal law."

But this week, everything changed for -- and because of -- Genny.

People reports that "Last week, Governor Chris Christie signed into law a bill – inspired by Genny – that authorizes parents or primary caregivers to administer edible medical marijuana to sick or disabled children at school, while protecting school districts from liability."

This is huge news for Genny, who'd been going to school for half the day in order to take her medication. In the coming weeks, she'll return to school full-time.

It's also relief for her parents, who'd been in court over the issue for the last six months. While Lora told People she's "very happy," she hopes the law will someday allow school nurses to administer medical marijuana.

"It's frustrating because is it a medicine or is it not a medicine?" she said. "What parent has the time to go into the school every day to do it?"
