Have any skaters ever been charged with illegal doping? Even if no one has been caught, what substances might some have in fact used? I am aware there was an incident with Marina Klimova, but I believe her tests were ruled false positives. I would speculate her results could have been affected by something as simple as birth control pills. I find it hard to believe female skaters would take androgenic hormones, but Irina Rodnina came out in 1992 and said steroid use was common in Soviet era skating.

What is the state of doping in skating today? It seems to me that training methods and preparation are so superior now that only unusual cases would resort to substances which could be of marginal benefit and potentially disqualifying.
But what about banned diuretics and stimulants? Those could be of some benefit. Are any skaters today using these?
