NASCAR has added the supplemental product ephedra/ephedrine to the list of banned substances under its drug policy, series officials confirmed Tuesday. On Dec. 30, federal officials announced it was moving to ban dietary supplements containing ephedra because of continued health concerns about the product. Last season, NASCAR advised its participants in all of its series to seek guidance from their personal physician before taking any supplemental product labeled as containing ephedra/ephedrine. Ephedra, which is extracted from an Asian plant, was already banned in college sports, the Olympics, the NFL and minor league baseball. Supplement manufacturer Stacker 2 sponsors the NASCAR Busch Series car of Kenny Wallace. That sponsorship should not be affected since Stacker 2 offers other non-ephedra products.(ThatsRacin.com)(1-7-2004)
