The affidavits were part of a request asking the court Monday for a mental and physical examination of Mayfield to determine if he suffers from a substance-abuse disorder and/or adult-deficit hyperactivity disorder.
Mayfield has sued NASCAR for suspending him for a May 1 drug test that it says was positive for methamphetamines but Mayfield claims produced a false positive reading as the result of the prescription drug Adderall (for ADHD diagnosed earlier this year) and over-the-counter allergy medication Claritin-D. He is also suing for defamation.
Mayfield has denied using methamphetamines in several interviews and court documents.
The new affidavits are from people who knew Mayfield from his home state of Kentucky, while the deposition is from driver David Keith, Mayfield’s former brother-in-law from his first marriage. The affidavits come from Barry Lee, Michael Buskill and Steven Russelburg, all of whom testified that they saw Mayfield use methamphetamine at his race shop or at his home in North Carolina.
Lee states in his affidavit that he saw Mayfield use the drug in 1999 on the way to Lowe’s Motor Speedway and that he had it in his possession during an unspecified race weekend at Indianapolis Motor Speedway.
Russelburg lived on Mayfield’s property from 2006 to 2007.
“During that time, I frequently saw Jeremy use methamphetamine, almost on a daily basis," Russelburg states in his affidavit. “Most of the time this occurred at a barn on the property that had been converted to a shop."
