Some Floridians could have access to a limited strain of medical marijuana by the end of the year.

On Wednesday, a Tallahassee judge dismissed the final challenge to the Compassionate Medical Cannabis Act.

It will allow certain people to be able to get the so-called "Charlotte's Web" strain of low-THC marijuana to help people suffering from epileptic seizures, cancer and other medical problems.

Five years ago, Branden Petro was a healthy, active child. Then suddenly and without warning he developed a rare condition known as Febrile Infection Related Epilepsy Syndrome or FIRES.

His mother, Renee Petro, said the family's life changed dramatically.

"And then suddenly in a split second -- dying really -- and we have another child ... it's so devastating in itself and to not know what happened to your child is very hard," said Petro.

Since then, she's been doing everything she can to help Branden recover. She said traditional drugs aren't working so she and Branden traveled to California to try medical marijuana.

"Well, for a month my son went seizure free and whatever they're doing in California, we need to have it here in Florida," she said.

She said it's been frustrating to not be able to give Branden cannabis once they returned home to Florida.

Petro said allowing "Charlotte's Web" in Florida is a start.

"Saving our loved ones life shouldn't be moving zip codes or moving states," Petro said. "It should be something that's available, that's readily available everwhere."

Petro said this particular strain hasn't proven effective for Branden but she hopes it will for others suffering from debilitating medical conditions.

In the meantime, she said she'll continue to fight for anything that could help her soon get better.
