I dont know much about allergies. I have a 9month old and he some type of allergy I belive. I was told to try to do allergy test at about 12 months. In your case it seems that the smoke could be the problem but there could also be other things as well! I know there is other medicine that you can give that wont be harmful like Benadryl and some others but I cannot seem to remember which ones! But I def say to do the allergy test (they say to wait till 1yr b/c things may change and its more accurate) I could be wrong! Im sure others will be by very shortley to help you out and give you lots of advice. Good Luck with everything and keep us updated!
