WEST Coast has greatly improved its practices and moved well past the infamous drug culture that enveloped the club in the early 2000s, AFL chief Gillon McLachlan says.

McLachlan's comments come after former Eagle Daniel Chick told News Limited that the 2006 team had a toxic culture of prescription and illicit drug abuse.

McLachlan indicated the League would look into Chick's claims but said he was adamant the Eagles were much better equipped to prevent a similar situation these days.

"I think we'd certainly make some enquiries, I don't know how far it goes, it is 10 years ago," McLachlan told SEN on Thursday morning.

"There was action at the time and the Eagles have changed their culture and they've been through a whole series of leadership changes and they're a model in this area."

McLachlan said he was taking the claims seriously.

"He's made allegations that are pretty strong and that obviously is something that will be concerning to everyone involved and I need to work through that, because there's two sides to the story," he said. 

Chick was a member of West Coast's 2006 premiership team.
