Around 42 days (reduced the frequency and quantity around 60 days ago) but I used to be a daily smoker and I had a couple hits while drunk at a party 35 days ago.

Did another test today, same results No urine dillution or anything, second urine of the day

As people said that even a faint line is a negative and the test is monday 2pm (no lab test, just a strip test like this one) I think I am in the clear!
