Here’s everything you need to know before you buy into the CBD madness. Despite the bill, companies still aren’t technically supposed to add CBD to food, drinks, and dietary supplements, CNBC reports. (Of course, this little fact isn’t stopping people from doing just that.) The Food and Drug Administration will continue enforcing the ban, CNBC adds, however, it may not be this way forever. In late December, the FDA announced it is researching pathways for allowing interstate sales of CBD-infused food and beverage products. Where there is perhaps the greatest scientific evidence proving the positive effects of CBD is with children living with Dravet Syndrome and Lennox-Gastaut, two severe forms of epilepsy. According to Harvard Health Publishing, numerous studies show CBD was indeed able to reduce the number of seizures experienced by children with these conditions. In several cases, the use of CBD was able to stop seizures altogether. Because of these studies, the FDA approved Epidiolex, the first ever cannabis-derived medicine, to help treat those conditions in late 2018. “The brain has these receptors that respond to endocannabinoids, which are neurotransmitters that are naturally produced in the body and brain,” Jerald Simmons, a neurologist at Houston’s Comprehensive Sleep Medicine Associates, told Vice. The endocannabinoid system, Vice adds, is not very well understood, but it is thought to regulate everything from our sleep to pain and even to cognition. “Some of the cannabinoids in the marijuana plant are very similar to the endocannabinoids in the brain, and they act on the same receptors,” Simmons said.
