In January 2007, Stan Lazaridis, playing for Perth Glory, failed a drug test for prescription alopecia medication, which is banned due to its potential as a masking agent for other performance-enhancing substances. He was found guilty by Australian Sports Anti-Doping Authority and was given a 12-month suspension from football. He had not taken the prohibited substance to mask a performance-enhancing drug but for legitimate therapeutic purposes as prescribed by his doctor.
