I don't know where the "comprehensive drug testing myth" comes from. I was not aware that anyone thought that every single athlete is drug tested both in every competition and out of competition.
Its general knowledge that drug testing is random in IPF powerlifting with world championship winners all tested and open world record holders all tested. But there is no way that every single amateur powerlifter is ever drug tested at every comp, in and out of competition.
Just the cost alone of current drug testing would bring tears to the eyes of any accountant.
Same goes for all the other drug tested sports, such as bowls, swimming and skeet shooting. I'm not certain but I think that even professional sports (e.g. AFL, NRL, etc) are not "comprehensively drug tested", whatever that means.
Compare that to other federations where no one is ever tested for anything. Ever. Even with a (cough) "no drugs allowed" policy.
Is drug testing "comprehensive"? No. Should you turn up at a comp expecting to be tested? You better, cos it will happen sooner or later.
Maybe someone can ask Steve Pritchard if he thinks he was "comprehensively" drug tested. If I remember rightly, he was hit with a drug test, on average, more than once a month for a 12 month period. I guess that counts if you are a tall poppy.
