Thousands of Chinese immigrant laborers suffer abuse and exploitation in a U.S. marijuana underworld dominated by Chinese mafias. A human rights advocate says: “They have not escaped the darkness of China.”

Today we speak with Frontier reporters Garrett Yalch and Clifton Adcock about their reporting series looking at Oklahoma's medical marijuana black market, as well as their new story about the human and labor trafficking allegedly done at some of these farms.
