I have a test and soon!

Question

I have to take a test and I use chewing tobacco & smoke the last time I smoked was yesterday at about 4 and I had 1 pinch this afternoon at about 12:50. I have a test comming up at about 9-9:30. Could I pass? Let me tell you what I have done first. I have sat in the sauna for about 45 mins, I've drank about a gallon of water and I worked out for about 2 hours, I also have been riding my long board around town for the last 3 hours. Is there any hope that I will pass this test?
