Gov. Phil Bryant signed a bill Thursday allowing a form of medical marijuana in Mississippi. "The bill I signed into law will help children who suffer from severe seizure disorders," said Bryant in a statement to 16 WAPT News. "Throughout the legislative process, I insisted on the tightest controls and regulations for this measure, and I have been assured by the Mississippi Bureau of Narcotics that CBD oil (cannabidol) is not an intoxicant. The outcome is a bill that allows this substance to be used therapeutically, as is the case for other controlled prescription medication."Bryant said he remains opposed to any effort to legalize marijuana or its derivatives outside of the bill.The bill was named for Harper Grace Durval, who turned 2 years old Friday, which is usually the age when children with Dravet's syndrome start seeing an increase in the number of seizures.Click here to watch the story"We hope we knew from the beginning that this was not a guaranteed thing," said Ashley Durval, Harper's mother.Mississippi joins 22 other states that have already legalized hemp oil medicine because researchers believe it reduces seizures in children like Harper."Hopefully, this will lead the way to some groundbreaking insight into, not only children with epilepsy, but any other neurological disorder," Sen. Josh Harkins, R-Flowood, said.Harkins is the one who pushed the measure. He admits that the toughest sell in some cases was convincing critics that it's not an open door for medical marijuana.There are still several hurdles to clear before any medicine is dispensed. Now that Bryant has signed the measure, federal officials have to approve how it's distributed. The next steps will be handled by the University of Mississippi Medical Center and the University of Mississippi.The only place that would grow and extract the hemp product would be the Natural Products Laboratory at the University of Mississippi. The pharmacy at the University of Mississippi Medical Center would dispense it.Dr. Brad Ingram said the goal is to use the cannabidol, also known as CBD, extract -- not tetrahydrocannabinol, which causes people to get high."Whereas most marijuana plants are a 20-1 ratio of THC to (CBD), what we are looking for are plants that are 20-1 the other way, so way more CBD than THC," Ingram said."She has them every day, but they are not grand mal seizures, and they are very short," Durval said.Durval is hoping to soon get a medicine that may delay or stop the seizures that doctors said are about to get worse.
