Amount Of Time You Have Passed A Drug Test In

ok ill try to keep this short, the end of my spring semester is almost over so it is time for me to stop smoking for my summer job. I usually give myself 4 weeks just to be safe but this year after one week I was partying with this girl I like and she wanted to smoke a blunt so of course I did and then I figured what the hell so I smoked pretty much all day the next day leaving myself about three weeks. I then got online and started looking at topics about drug tests detection times, and although there is an endless supply of drug test related questions every one seemed to have conflicting answers ranging from a week to sixty days to my uncle has a friend who has a brother who did it in three days. So I was just wondering how long it may have taken some of you, (real life, not stories you've heard please) because I have always heard that you should be able to pass at about two weeks if you dilute your urine enough the day of the test, and some of these so called "facts" I read online seemed pretty out there to me.
