Officials say it is business as usual the following say and workers are focused on turning out a quality product.
"We have some of the highest standards in the industry that you will find anywhere, our quality has not been compromised," Union President Darryl Jackson said.
ABC11 Eyewitness News has learned undercover officers spent seven months inside the plant posing as workers, after Goodyear's corporate officials in Ohio asked the sheriff to investigate drug activity in the tire plant.
"They have been very supportive, they allowed us to do work within the plant and try to bring an end to this," Sheriff Earl Moose Butler said.
But the arrests have raised the question, were some workers high or stoned on the assembly lines.
When asked if drugs were a problem on the production line, a Goodyear spokesman says quality control wasn't compromised.
"One hundred percent of our tires are being screened for quality before they leave the plant," an official said.
Union officials say they and the company have a zero tolerance drug policy and they were not aware of any widespread problems.
"Everyone knows to some degree there is a drug problem," Jackson said. "No matter where you work, but to talk about specifics, no we did not have knowledge of these specific problems in our plant."
Meanwhile, All 15 employees arrested have been fired. A spokesman for the United Steel Workers Union says eight workers were hourly employees, two were salaried workers and five were outside contractors.
They are all out on bond and have court appearances in late April.
