A member asked:

What do you suggest if i need to pass a cotinine test?

A doctor has provided 1 answer

Don't smoke: Cotinine persists for 3-5 days, depending on whether they are testing urine, blood or oral fluids. There are far more important reasons to stop smoking, like your health and living a longer life, and not smelling like an ashtray.
