Mourinho famously dumped Fabio Coentrao at Real Madrid after he was snapped by the Madrid press having a cheeky fag.
"What football players do, millions and millions are watching, lots of kids are watching," said the Blues boss.
"I’m not a specialist, obviously, but I don’t think if a football player smokes one cigar or cigarette with friends in the summer when he is not training – I don’t think it affects his performance.
"What gets affected is that a kid at home says if a top football player can smoke then I can smoke and it is not a problem.
"It is more a social consequence than a physical consequence.
"Would I be angry if it was my player? Being angry is not a solution but I would just explain exactly that, that everything they do or wear is part of the kids’ life.
"If they smoke, maybe the kids think they do it a lot of times and they will probably do the same."
