Carter Ashton has been suspended for 20 games for violating the terms of the NHL and NHL Players’ Association’s drug policy.Ashton says he unknowingly ingested prohibited substance Clenbuterol through an inhaler used to treat asthma. “I now recognize that I ingested Clenbuterol, a prohibited substance, through the inhaler,” he said in a statement.“However, at no time was I seeking to gain an athletic advantage or to knowingly violate the terms of the program. I used the inhaler in response to exercise-induced asthma, a condition that my doctor with the Toronto Maple Leafs has since diagnosed and he has prescribed me with an inhaler.” He is not eligible to play again until December 20th vs. the Flyers.
