still positive after 3 months

I am still testing positive after 3 months of not burning.Does smoking tobacco interfere with the test??.or are my strips not working???

What is your smoking history, age, height, weight? also if you work out or not? Knowing this information can give us a better idea of why your still failing.

I am 44 years old 5' 6'' 160lbs.I used to smoke 1/4 a week for over 18 years and i work out a little

Go for a few runs and sweat it out!

3 Months that's a long time damn

Is this for a probation test or pre-employement? If its just for a job research subbing with synthetic urine. You can try eating a high fiber diet and metamucil.
