Reports have emerged that at least four Collingwood players voluntarily admitted to using drugs last season.
According to the ''Herald-Sun'', the Magpies' players reported their drug use to AFL medical staff late last year and as a result they did not have a strike marked against their name under a controversial clause in the AFL's Illicit Drugs Policy.
Under the policy, if a player fails to respond to treatment and counselling on three occasions, they are subject to a $5000 dollar fine and a suspension of up to 18 matches.
However, if a player reports to using drugs, whether that be deliberately or inadvertently, then they are exempt from having a strike recorded against their name.
The news comes ahead of the AFL holding an historic summit on drug use in the competition on January 30.
