I have 2 brain avms, one of which takes up a quarter of my brain and in addition to this I have one large coiled (13 coils) varix. A friend of mind has a sister who also has a brain avm and she has been told to avoid cigarette smoke at all costs. I do not smoke myself but wonder what effects inhaling secondary smoke can have on my brain? I would be grateful for any advice you can offer.
Hi, Passive smoking does not affect Arms. However, it is a major risk factor for stroke, heart attacks and cancers.  Hope I have answered your query. Let me know if I can assist you further.
