Vaping before surgeon's nicotine test

[DIANNE PERKINS]

I quite smoking on December 14th.  I bought non-nicotine vaping with menthol flavor.  I can't find decisive answers about my testing coming up within a week.  I was told at the vape store that there is absolutely no nicotine in the juice and the menthol is called GNS Menthol.  Can this website please help me determine if I will most probably pass a blood or urine test?  I honestly don't know, it could be a swab test.  If the surgeon finds any nicotine in my system the day of the surgery, th 31st, he'll cancel it.  I'm trying the best I can.   I just can't stop cold turkey with the smoking and the vaping is fabulous.

If anyone has suggestions I'm sure open to them.   BTW, I'm taking 100-200 mg of Wellbutrin to help with easing off the smoking as well as Niacin - 250mg.  

I would appreciate any help possible as I HAVE to get my hip replaced asap.   Thanks for reading and possibly helping with this.
