NASCAR's Mayfield fails second test for methamphetamines: Driver Jeremy Mayfield has failed a second drug test for meth, NASCAR officials announced. Mayfield, who was suspended in May but had his ban lifted by a court order, is also being accused of using drugs before at least one race by his stepmother. His response: "Now they got this lying [expletive] to tell lies about me, someone I am embarrassed even uses the Mayfield name. She's tried everything she can do to get money out of me. I won't help her, so I guess she found a way to get money from NASCAR by giving them an affidavit full of lies."
