As the fallout from the explosive Australian Crime Commission (ACC) report continued on Thursday, West Coast toured regional town Northam for its community camp.
Glass said he had been shocked by news that Essendon was the subject of an Australian Sports Anti-Doping Authority (ASADA) investigation, and he was still coming to terms with the ACC report.
The All Australian captain said knowing his opponents had taken illegal supplements would not be his major concern if performance enhancing drugs have spread through the AFL.
"I'd just be devastated for the game. Not necessarily feeling cheated personally, but devastated," Glass said on Thursday.
"Obviously there's a lot to come out yet and we’ll learn more in the next few days.
"Performance enhancing drugs have been a part of sport for a long time, but it does take away [from it].
"I used to enjoy watching the cycling, but you can't help but think of it as a dirty sport. Hopefully the Australian sporting codes don't get branded like that."
Glass said West Coast had been using legal supplements for a long time, but only in powdered form and the players were not allowed to source their own products.
"The club is very diligent and the players are only allowed to get supplements from the club that have been checked by our medical team," he said.
"We're educated that there are supplements on the market that contain illegal stuff, particularly the stuff from the States that you can buy online.
"We’re educated hard on that stuff and we're only allowed to take supplements that the club has approved and they give us."
Glass said he had never needed to address the issue of performance enhancing drugs with his teammates and would be "very surprised" if it ever became an issue at West Coast.
