In a word, yes.
In tennis about 80% of the anti doping is carried out by the governing body the ITF who just sweep their positives under their carpet
In Cycling about 60% of anti doping is carried out by the governing body the UCI who bury things under the carpet, but also saw in the biological passport. The rest of the testing is carried out by national anti doping agencies, USADA, AFLD etc
In all olympic sports, the testing is conducted by the national anti doping agency, USADA, CONI etc who work in partnership with the countries olympic committee.
In all of these sports the members of the anti doping bodies are experts in the field, with numerous experts who understand doping, with medical backgrounds, the state athletic commissions are best described as jack of all trades, master of none. They simple dont have the anti doping knowledge required
One thing they do have in common, ITF in Tennis, UCI in Cycling, State Athletic Commissions in MMA and Boxing is a lack of independance. There is a push in cycling to have anti doping moved away from the governing body and into totally independant Anti Doping. MMA anti doping will only be taken seriously when moved to a totally indepedant body (ie. USADA in the US, etc)
