Hi Im having a cotinine or nicotine test in 7 days. Ive been nicotine free for 4 days. drinking lots of water and hoping to pass this test. Can anyone tell me if they have had to do this? I was a heavy smoker till January 1st then gradually weened myself off. Now I have been nicotine free for 4 of the 7 days and wondering if I should even go through with the test or put it off for a few more weeks.
