Tony Pulis believes the Football Association should name and shame players who have served drug bans.
Thirteen footballers have tested positive for recreational drugs since 2012, but their identities have been kept hidden to aid the players' rehabilitation.
Asked if the FA should make positive tests public to avoid the kind of spat that followed the Saido Berahino case, West Brom boss Pulis said: 'Of course. It is that line between personal and public. That is for other people to decide (but) I have my own thoughts on it.'
But Stoke manager Mark Hughes defended the FA's policy of confidentiality.
