The World Anti-Doping Agency (WADA) says financial constraints and a general boredom with the issue could undermine the fight against doping.
The WADA president John Fahey says the organisation should start looking for new sources of funding from the sports industry itself, rather than relying on the International Olympic Committee (IOC) and national governments.
The IOC currently provides 50 percent of the budget with the rest split between various national governments.
Referring to match fixing and the tough economic times Fahey says WADA must ensure that sporting bodies and governments do not take their eyes off doping in sport, simply because there is another threat which seems to be gaining momentum.
Fahey welcomed yesterday's decision by the Court of Arbitration for Sport (CAS) to ban Alberto Contador for two years after the Spanish cyclist failed a doping test during the 2010 Tour de France.
