Every child in Colorado who has been given medical marijuana for treatment for seizures has had diminished seizure activity. -- State Rep. Allen Peake, R-Macon, during a House of Representatives meeting March 3

An important debate is ongoing in the Georgia Legislature concerning the use of a form of medical marijuana to treat certain forms of seizures.

The state’s House of Representatives overwhelmingly passed House Bill 885, which would allow for the use of medical research cannabis in specific cases. The Atlanta Journal-Constitution’s new Legislative Navigator gives it a 27 percent chance of passing the Senate this session.

The bill’s primary sponsor, Rep. Allen Peake, R-Macon, offered what appeared to be a persuasive argument to support the legislation.

“(In Colorado), 100 percent of children have seen diminished seizure activity,” Peake told fellow House members during discussion on the bill.

PolitiFact Georgia wondered whether Peake’s statement was correct.

Peake said he was persuaded to get involved with the issue after meeting a 4-year-old girl from his area named Haleigh Cox who suffers from a severe seizure disorder.

Peake said he based his claim on information from the Realm of Caring, a Colorado-based organization that has attempted to provide care to patients suffering from cancer, AIDS, Parkinson’s disease and other conditions through the use of medicinal cannabis oil. Peake clarified his statement, saying that it was actually 98 percent of patients who had diminished seizure activity.

Marijuana contains about 60 chemical components called cannabinoids. The cannabinoid that the bill’s proponents are considering is cannabidiol. It would be ingested and not smoked, the bill’s supporters say. It would not include THC, which is the element in cannabis that causes smokers to get high.

The form of cannabidiol used at the Realm of Caring is named Charlotte’s Web, after a 5-year-old girl whose recovery from a rare condition is credited to the substance. Charlotte’s Web is a rich amber and as thick as cold honey.

Heather Jackson, the executive director of the Realm of Caring Foundation, said Peake was correct that every patient studied in the first set of tests, “harvest” is the term she used, had a reduction in seizures. The Realm of Caring is in its second harvest and has seen less than a handful of nonresponders, which accounts for Peake’s revised 98 percent total.

The New York Times, though, reported in December that there is “scattered medical research” to substantiate claims cannabis oils helped reduce seizures, citing a 2012 study on the American Epilepsy Society’s website. Other researchers have also cautioned there is not enough research on its medicinal benefits.

The American Epilepsy Society wants “well-controlled studies” it believes will lead to a better understanding of the effectiveness of cannabidiol and other forms of medical marijuana on epilepsy patients.

Amy Brooks-Kayal, a Colorado-based neurology physician who is first vice president of the American Epilepsy Society, said there’s not enough information to determine what the dosage should be or how it interacts with other medicines. The AES, which claims about 3,500 members, said although cannabidiol offers hope, these are only anecdotal reports. Robust scientific evidence for the use of marijuana, it said, is lacking.

The federal Food and Drug Administration has authorized trials of an established British drug, Epidolex, that comes from marijuana. Some experts who believe Epidolex is a better option say it’s unclear whether Charlotte’s Web is free of potentially harmful impurities.

Jackson offered us two studies in defense of the treatment. In one study, all 11 children studied showed a reduction in weekly motor-type seizures, the study concluded. After three months, five of the 11 children were seizure-free, the study found. The paper, introduced at the American Epilepsy Society’s annual meeting in December, acknowledged the sample size was small.

In the other study, two Stanford University researchers asked parents whose children were using cannabidiol to fill out a survey detailing its impact on their children. Sixteen of the 19 parents reported reduced seizure frequency. Three parents said their children were free of seizures. The most often reported side effects were better mood, increased alertness, better sleep and drowsiness. Common side effects with other forms of treatment were not found, the parents said. Jackson said 13 of those 19 parents had children who were using Charlotte’s Web.

Jackson said they are doing more research.

Jackson said in the cases in which Charlotte’s Web did not result in fewer seizures for the patient, “there is less than a 1 percent chance that a child in this intractable epilepsy population will find one that will work.” Charlotte’s Web, she said, has performed better than other forms of treatment.

“There is not a treatment in the world that will work for all,” Jackson told us. “However, it is important to note that there is not a pharmaceutical in the world that works for even 5 percent of the epilepsy population. So the numbers are quite staggering actually.”

Peake said he was not deterred by questions or concerns about the research.

“The anecdotal evidence is so strong that a parent, in conjunction with their doctor, should have the personal choice to make that decision,” Peake said.

To sum up, Peake said “every child in Colorado” who has been given medical marijuana for treatment for seizures has had diminished seizure activity. Peake then said it’s actually 98 percent, citing newer data.

There are very few studies out there. They do show medical marijuana has a positive impact on seizure activity. But not at the levels Peake said.

His statement is partially accurate. But it needs a lot of context to be fully understood.

We rate it Half True.
