U.S. health officials are urging states to regulate marijuana oil extracts after investigating a rash of illnesses tied to the products in Utah.
In a report released Thursday, the Centers for Disease Control and Prevention found that synthetic products falsely labeled as cannabidiol, or CBD, sickened as many as 52 people from October through January.
The CDC urged states to set up regulatory and control systems “to minimize the risk for recurrences of this emerging public health threat.”
CBD is derived from cannabis but is designed not to produce a high. Users say it provides relief from pain and can fight seizures.
