I am taking an oral swab drug test on Monday morning at 9:00am. I was a heavy/daily smoker up to 6-7 weeks ago when I went cold turkey. This morning, Saturday, I passed an at home urine test, I used the first pee of the day, I heard this is the most toxic. Given the weeks in which I have not smoked and the negative urine test what are my chances of passing? Should I take any precautions like beath mints, etc... Is it true that the window for a saliva test is only 2-3 days and that the toxins stay in urine much longer than saliva? Please help I am nervous, I was a heavy user for the last 18 years.

thanks in advance,
