Annalise Lujan, 12, (left, before she was sick) was diagnosed febrile infection-related epilepsy syndrome in April. The condition causes her to have seizures continuously. She was put in a medically induced coma to save her from brain trauma (right in April)

While the cannabis derived drug was useful in Annalise's case, medical experts are still divided on its overall effectiveness. 

Former Surgeon General Vivek Murthy admitted marijuana could be helpful in treating certain conditions but cautioned that there needs to be more research.

In a groundbreaking study, scientists at New York University and Great Ormond Street Children's Hospital found cannabidiol halved a rare epileptic seizure. 

This marked a major milestone in efforts to introduce the drug as an effective treatment plan. 

However, other experts claimed the study wasn't as promising because the patients were also taking other drugs.

Scientists are expressing the need to further examine the medical benefits of cannabis before it is made readily available to patients.   

When Annalise's parents first brought her to the hospital, the medical experts thought she had a stomach virus.

Estrada-Lujan said to KVOA: 'One day, she was just a healthy young lady, going to school, participating in her community and her gymnastics, and the next day - fighting for her life.

'She was put on a ventilator, and put into a medical coma, and, we haven't talked to her since.'

Symptoms of FIRES normally appears one day to 14 days after a child has a mild fever. 

Seizures start slowly before getting worse, with some children having 100 seizures a day. FIRES is extremely rare, with one in a million children contracting it. 

It happens when a virus spreads to the brain or autoimmune system after an ordinary cold or stomach flu.

Now Annalise is no longer plagued by constant seizures and is in therapy (pictured in May) to regain her cognitive abilities.

Regular epilepsy medications aren't successful in treating FIRES, so Estrada-Lujan began looking for a solution elsewhere.

She learned that cannabidiol has been studied to treat epilepsy conditions and pushed for its use in her daughter's treatment.

The oil has very low levels of THC, which is the substance responsible producing the 'high' in marijuana. 

Since the substance wasn't approved at the time, Annalise's doctors had to rush for its approval with the FDA and DEA.  

Less than two days after Annalise's first treatment, she was cured of the constant seizures on May 8. 

Estrada-Lujan added to KVOA: 'She opened her eyes, and she was scared. She was afraid. She cried. And, I whispered to her that she was very strong, she's beautiful, and she's strong, and she needed to keep breathing, and she did.'

Now Annalise is in recovery and will need therapy to regain the same cognitive functions that she had before. 

Cannabidiol oil was found to be successful in treating other forms of epilepsy. 

A recent study by New York University and Great Ormond Street found the syrup, taken once a day, reduced the convulsive seizures by 48 percent in under-18s with Dravet syndrome, a rare and severe form of epilepsy. 

Experts don't considered it as a 'cure' - because patients have to keep taking it every day for the benefits to last.

They also still do not understand precisely how the cannabis compound controls epilepsy symptoms.

It is thought to act on the endocannabinoid system, a network of molecular receptors in the brain and nervous system that not only generates the cannabis 'high' but is linked to a wide range of physiological processes. 

Around three million Americans and more than 600,000 people in the UK suffer with epilepsy and for a third of them drugs do not work to control their symptoms.
