I think you will be fine however your post did surprise me, I have never heard of a healthcare facility testing for nicotine before and I am having a hard time understanding why they would. Nicotine is not an illegal substance. What if a potential employee has quit using tobacco and is using nicotine gum, lozenges, or the patch; does that mean they would not be hired? .... anyway, good luck! I hope you get your dream position!:)
