Hello! I am very nervous now because I have my BA and TT scheduled for the 29th only 3 days away and I've just come back from a birthday party where I was exposed to second hand smoke. The party took place outdoors so you think I could have been able to get away from it! I have never smoked a cigarette in my life so I hope this doesn't affect my healing. Can you please give me some insight into whether or not I should be concerned. Thanks a bunch!
