answered question 9/29/2010 How Long Do 4 Hits Of Chronic Weed Stay In Your System? I Hit The Bong Four Times On Sunday, And I Have A Urine Test On Tuesday. Will I Pass? Yeah, sorry to say, but you will be detected. I've smoked for years now and the only way you can smoke in a similar way to that is if you have about a week's time before the test. It will show up.
