how old are you??? If your 16, you shoulda been like no, i don't want a test, i think i might fail because i was a chronic smoker, from what i know marijuana stays in the urine for 3-12 weeks... And he can't give you a piss test anyway. He ain't your PO and he ain't your rents... Your gonna fail and he will tell your parents, if you smoked chronic as much as i think you did, there's no way you could pass, even with 2 weeks of no chronic. If it was a blood test, you would pass for sure, but urine test, no way. I gotta say, if your 16 you made a big mistake lettin our parents drug test you, i made the mistake, failed, told the doc not to tell, quit for 6 weeks and then didn't even get urine tested, just blood tested. Blazed the day before and passed lol
