Jeremy Mayfield believes NASCAR is using him as an example.
Mayfield was suspended by NASCAR on May 9 after testing positive for methamphetamines, a violation of the substance abuse policy. He spoke to ESPN's "Outside The Lines" on Wednesday.
"[NASCAR wants to] get the message back to other drivers in the sport," Mayfield said. "To put the fear of God into them. To scare the other drivers. And crew members and everybody out there. I think it killed two or three birds with one stone there with the policy. And it put the fear of God in other people and other drivers who have tested positive that they didn't put in this situation."
Mayfield filed a lawsuit against NASCAR. It is set to be heard in a trial jury beginning on Sept. 13, 2010. Mayfield contends he did not take methamphetamines and is seeking to be fully reinstated. He also is seeking damages.
Mayfield said NASCAR banned him to scare other drivers who have tested positive.
"This was sending a message to them saying, 'You better straighten your act up', without putting them through what they put me through," Mayfield said.
NASCAR spokesman Ramsey Poston responded with this statement: "The facts are clear and now recognized by the court, that Jeremy tested positive twice for methamphetamines. He was offered the chance to undergo the road to recovery but chose to go the legal route."
