All those people criticizing fmc_apprentice are just not getting it. The reason he has to speak here anonymously is that he fears Ryanair would sack him if he made a big deal. Whether they would or not is open to debate, but as others have remarked earlier, in order to advance up the airline system you need the right mates at the right time. If he is seen as a 'splitter' then nothing needs to be said - he will just fail an LPC or a Line Check one day. He would therefore by definition be 'incompetent' as a pilot and he is finished - it is that easy.
I have to say I am simply astonished at this thread - I simply did not know there were any credible airlines in the world who would tolerate this situation. I am even more astonished to find out that Ryanair, having been embarrassed by this thread into re-iterating the no smoking ban, are tolerating the flagrant abuse of it in the last few days. The issue is not health or smoking per se, however important that may be. It is that a company rule, despite being re-issued is being overtly disregarded with impunity. This is simply unacceptable in any airline and is a clear indicator that company rules at Ryanair are open to 'interpretation' and if necessary disobedience if the expedient of the situation demands. Is there no manager at Ryanair who has the courage to deal with this? This is not the problem of a few highly strung F/Os - this is a major management issue.
All you managers at Ryanair - are you going to enforce your own rules or not? This whole situation is reminiscent of those yobs who get nicked for throwing bricks over bridges and killing swans - there is no one more surprised than them that the swans were hit as they were sure they would get out of the way. No doubt you will be utterly surprised when some far more disastrous incident occurs to a Ryanair aircract. After all, how could it have happened - there were clear rules that if followed would have prevented it.
