I vaped all through my preop period. It never came up and I never thought about mentioning it. After my pre op testing, they found very high levels of Nic in my system....which honestly, I didn't even know they check for that.
My CRNP asked about my nic levels and I explained that I used to smoke but quit and started vaping instead (I quit ciggys in 2014). She said she'd let the surgeon know and told me to stop right away...but I was already only a week or two pre op. she explained that smoking is a deal breaker for surgery, but given the circumstances she would talk to the Dr. I did vape right up until the day of surgery. I noticed no ill effects from it, but I didn't start vaping again until several weeks after the surgery. After surgery, it just didn't seem appealing, which was a surprise. I thought I would be the guy sneaking vape hits in the bathroom....but it just wasn't appealing at all. Looking back, that would have been a great opportunity to completely give it up, but since I felt like I gave up so much already....I went back. I make my own juice, so I still put a very small amt of nic in (less than 2 percent). So, it is what it is, I guess.
