Western Bulldogs coach Luke Beveridge has called for the AFL illicit drugs policy to be scrapped as Bailey Smith faces suspension under the controversial system.

Star midfielder Smith will be interviewed by the AFL integrity unit on Tuesday after being caught on video with illicit substances last year.

The video and images emerged last week, with Smith later apologising for "indulging in behaviours in late 2021 of which I am deeply ashamed".

The 21-year-old, who is currently serving a two-match suspension for headbutting an opponent, could be hit with another ban for "conduct unbecoming".

The West sport chief of staff Glen Quartermain explains why he's backing Bailey.
