I Am Going To Have Neck Surgery In About A

I am going to have neck surgery in about a month. In 3 weeks I am being tested 4 nicotine levels and I was a heavy smoker for 35 years. I have cut backto 5 light cigarettes a day and I Vape 3 milligrams juice. Will I pass the nicotine level test in 3 weeks if I cut back to 223 ultra light cigarettes a day and use 0 milligram Vape juice.?
