I think I will still have to cut down to zero; I thnk nicotine restricts blood flow. When the time comes, hopefully I can talk to the anesthesiologist in advance.
Definitely. If you are in the hospital for a procedure that could be impacted by any substance...nicotine, caffeine, etc. you should always let your Dr. know and get advice in advance.
I mentioned vaping in the room, because my wife was in the hospital for a few days last year due to complications with her MS and she did vape in the room. However, she was not having any operations or procedures being done either.
