MiniN - I don't like smoking either, but it's how you deal with it that determines whether your bf tells you or not. If you rant and rave, and make him feel awful, that's when he's most liable to lie about it. If you've no reason to suspect him of lying over other things, then I think your best bet'd be to try and help him. Smoking's a nasty addiction, but nagging him into packing up won't help, because he has to want to do it for himself. Have a proper talk with him, and suggest ways in which he might be helped, such as joining the New Leaf programme. With support & encouragement, he's less liable to lie about his habit. x
