During the 1980s and 1990s, Dr. George Zahorian was thought to have routinely distributed steroids and other drugs to WWF wrestlers, supposedly with the approval of WWF owner Vince McMahon.
In 1993, McMahon was indicted in federal court after the steroid controversy engulfed the promotion, forcing him to temporarily cede control of the WWF to his wife Linda.

The case went to trial in 1994, where McMahon himself was accused of distributing steroids to his wrestlers.

One notable prosecution witness was Nailz (real name: Kevin Wacholz), a former WWF performer who had been fired after a violent confrontation with McMahon.
Nailz testified that McMahon had ordered him to use steroids, but his credibility was called into question during his testimony as he repeatedly stated that he "hated" McMahon.

The jury would later acquit McMahon of the charges and he resumed his role in the day-to day operations of the WWF
