The Forensic Chemistry Center in Cincinnati operates under the authority of the U.S. Food and Drug Administration. As a result, it’s a secretive place, and FDA officials declined repeated requests to tour the lab or speak with its leadership. An agency spokeswoman answered questions that The Cincinnati Enquirer submitted by email.

“More than half of the vaping liquid products have undergone some form of evaluation, and additional testing on these and other samples continues daily,” the FDA said. “Many samples have contained little to no liquid, which limits the number and types of tests FDA is able to conduct on each submission.”
