NASCAR driver Jeremy Mayfield has denied ever taking methamphetamines.

Lisa Mayfield said her stepson told her he used meth before a season-ending NASCAR awards ceremony while driving for Ray Evernham. She also said Mayfield used meth during a 1999 trip to Myrtle Beach that preceded a race at nearby Darlington Raceway.

“We left Myrtle Beach and traveled to Darlington for the race,” she wrote. “I saw Jeremy using methamphetamine again when we reached Darlington.”

Mayfield said all of Lisa Mayfield’s claims were lies based on being monetarily cut off following her husband’s 2007 death.

“She don’t deserve the Mayfield name,” he said. “She’s hated me since my dad got killed because I won’t give her any money. She goes on the Internet and blogs lies about me and Shana (his wife) and everything you can imagine. She’s broke, and I guess she got NASCAR to give her some money.”

Mayfield also said he has independently been tested at least six times since his failed May 1 test, and all came back negative.

Meantime, Mayfield’s lawyers filed their response Wednesday to NASCAR’s motion last week to overturn Mullen’s injunction.

The brief, which didn’t include the results of Mayfield’s latest drug case, argued NASCAR was trying to “fashion the rules to their liking” by not meeting the requirements needed to overturn the ruling. Mayfield’s lawyers argued Mullen had correctly ruled that Mayfield faced irreparable harm from a suspension and doubts remain about the accuracy of NASCAR’s testing policy.

“NASCAR is absolutely corrupted by power, and its untenable motion to stay should be denied,” his lawyers wrote.
