UCI has been waging a war against the Tramadol for years. The drug, an opioid painkiller, had been considered banned in the context of competitive activities organized by the UCI since 2019, which made them sort of pioneer, given that the substance in question will become a part of the list of substances banned by the World Anti-Doping Agency only from January 1st.
The war in question seems to have borne fruit: Aigle reports that the use of Tramadol in the various groups has now disappeared. "The percentage of use of Tramadol in cycling has fallen from between 4 and 6 percent in the period before 2019, to a figure between 0.2 and 0.5 percent following that date," UCI boasts about their success.
