That is a tough one. I am not sure of that as things are different here in the states. Here they cannot discriminate but proving that could be very hard. I think some of it depends on the wording you used for why you were seeing the dr. Some people hear the C word and a business thinks about time you might need to take off etc. I hope that you get the job and that this biopsy come out negative. Good for you to not take your doctors word and went to see your dentist and oral surgeon. Keep standing up for yourself and congrats on the smoking thing.
