State senators are scheduled to vote Thursday on a bill that would decrease the maximum level of THC, the active ingredient in cannabis oil allowed in Georgia, from 5 percent to 3 percent.
Lisa Ganser is an assistant professor of molecular and cellular biology at Kennesaw State. She does research on how cannabis oil relieves symptoms of spasticity - like Parkinson's disease and epilepsy.
"A lot of anecdotal support has come in, and certain trials have come in that have said that decreasing the amount of THC or the concentration of THC in cannabis oil does seem to lower its affectivity," Ganser says. "What we've done in the lab has certainly supported those data."
Sen. Allen Peake, who introduced the original medical marijuana bill, says he doesn't understand the rationale for dropping the percentage of THC.
"It's not been a public safety hazard," Peake says. "There's not been a public health issue. And there are a lot of people who have been benefiting from the medical cannabis oil with the elevated level of THC."
Peake says he will fight to keep the law at 5 percent.
