'Gold Rush': Cannabidiol Industry Booms Amid Uncertain Regulation

"Shea Castleberry works in a time capsule of sorts. He walks through the aisles of the Family Video store he manages in Murray, Ky., a small city surrounded by rolling farmland about two hours north of Nashville."

"Next to the movies and popcorn, there's a new addition to his store that surprises some of his regulars."

"'A lot of people are like 'a video store selling CBD?' But it really does tie into our values. Which is, we're here for the community,' Castleberry said."

"Cannabidiol, also known as CBD, is a compound that is increasingly becoming popular because of the alleged health benefits users report, ranging from better sleep, reduced anxiety and pain relief. Yet clinical studies are lacking for most claims."

"It's derived from a type of cannabis called hemp, and the latest Farm Bill signed by President Trump in December legalized the cultivation of the crop at the federal level."

Retailers across the country, including Walgreens and CVS, have invested in the CBD industry since that point. Castleberry said his Family Video store began carrying CBD oil, lotion, gummies, lip balm and water, in April. But he stressed Family Video isn't just selling CBD just to get extra profit.
