Tramadol has been for a long time widely debated in cycling, specifically whether it is considered as
doping or not. The answers varied, but ultimately from January 1st they will enter the ban list for the sport and authorities warn against it's use, or the procedure to undertake if they are required.
“It is important that every athlete who uses tramadol is informed of this change in a timely manner. We therefore request that this message be spread widely within the sport," the Dutch
doping authority wrote. “Athletes who use tramadol must request a dispensation. In addition, it has been shown that tramadol can improve sports performance. Outside of competition, tramadol is not checked for. However, WADA has determined a detection time of 24 hours. As a result, use outside of competition can still lead to a positive test within competition.”
