On Thursday French researchers revealed details of the hair test they created for Tizanidine in a document published in the Wiley Analytical Science Journal by Pascal Kintz, Laurie Gheddar, and Jean-Sébastien Raul.

Cyclingnews is the world's leader in English-language coverage of professional cycling. Started in 1995 by University of Newcastle professor Bill Mitchell, the site was one of the first to provide breaking news and results over the internet in English. The site was purchased by Knapp Communications in 1999, and owner Gerard Knapp built it into the definitive voice of pro cycling. Since then, major publishing house Future PLC has owned the site and expanded it to include top features, news, results, photos and tech reporting. The site continues to be the most comprehensive and authoritative English voice in professional cycling.
