48 - 96 hours is what the lab tech at my hospital just said. Depends on how much you've smoked, too, in that time.

I have to ask the obvious. What were you thinking when you made the choice to smoke knowing you had a swab test within two days?
Dave Byrd Reviewed by Dave Byrd on . FBR ( or anyone ) Please help FBR- I hear you are the person to ask about drug testing. I have a mouth swab test in the next couple days. The last time I smoked was a couple hours ago. From what I have read on these boards, most of the tests detect within 48 hours, but some go back 96. I do know that the brand of the test is Instant Technologies. Do you know what the window is for that brand of test? Rating: 5
