I know it's probably none of my business but my friend smokes between 15-20 a day and is pregnant . Should I say anything or keep my thoughts to myself on this subject ? She says it's her only vice and has gave up drinking so why shud she give up the tabs ? I have resisted giving her my thoughts as I don't know if I should say anything as I don't want to over step the mark . I get it's an emotive topic but I can't help but feel 15-20 cigarettes a day is bad for her unborn baby .
