The Brownlow Medal winner made a highly publicised appearance on Nine Network football panel programme The Footy Show and revealed he has never had a strike under the AFL's illicit drugs policy.
Swan was paid $20,000 for the exclusive tell-all.
But, the paid interview incensed Collingwood's hierarchy, who claim to have had no knowledge of it until it was spruiked heavily by Nine in the afternoon before the broadcast.
Magpies president Eddie McGuire was furious his club had been left in the dark by Nine, Swan and his manager Liam Pickering, declaring if he could he would have fined the star on-baller $25,000.
The maximum a club can fine a player is $5,000 but the sanction slapped on Swan is not believed to be that much.
Swan pulled no major shocks during the interview, only conceding he was "no angel" and had a much more active social life than most in the game.
But the main theme of the night was Swan's dismissal of innuendo that he was one of the players who had self-reported to avoid an official drugs strike against his name.
"I'm clearly not an angel," Swan said.
"I suppose I probably go out a little bit more socially than the normal footballer.
"Maybe I am a little bit of what they call a lad and I have a laidback attitude and like just to relax and have a bit of fun, I'm not footy, footy, footy all the time.
"So maybe I'm not doing everything I possibly could to get myself 100 per cent for game day.
"But I'd like to think since I got suspended last year I certainly have.
"And I'm hoping if you ask the coaches at the footy club and all the players that I certainly am a lot better this year than I ever have been."
Swan also said he did not use performance-enhancing drugs but was tested six or seven times for them last season in what he believed was targeted testing.
"If you see what I look like and the way I run I clearly do not use performance-enhancing drugs," Swan joked.
He said he had no problem with chief executive Gary Pert or other Magpies officials confronting him at times over his behaviour.
"We've had a couple of frank conversations and I realise where I'm at and I'd like to think that they know how I'm going and where I'm at too," he said.
