Mayfield disputed the drug test, claiming the positive results came from a mix of the prescription drug Adderall and an over-the-counter allergy medication.

That legal challenge proved unsuccessful and any credibility Mayfield’s case might have had evaporated on Tuesday night when the 42-year-old was arrested and charged with possessing 1.5 grams of meth at his Catawba County home in North Carolina.

Mayfield, who posted $3,000 bond, but the drug possession charges may on the be the tip of the iceburg after Lincoln County detectives found roughly $100,000 worth of items belonging to local businesses that were reported stolen in late 2010 and early 2011.

In an e-mailed statement, NASCAR spokesman Kerry Tharp said NASCAR would be keeping a close eye on the upcoming legal proceedings.

Reports of Mayfield’s arrest stung NASCAR fans and media members who continued to hold out hope that the well-liked up-and-coming driver had been the victim of a tainted drug test.’s Larry Woody was one of those people.

“Despite all the revelations, I still believe that the same Jeremy is there. But unfortunately there’s another side that we didn’t detect.

“Hopefully Mayfield can conquer his terrible demons and get his life back. His racing career is over, but there’s much more at stake than losing a good racer. I don’t want to lose a good person as well.”
