did I screw up during urine test? please help!!

omg...a month without smoking...my mom is a nurse that gives these tests and she told me that b4 any test i should wait 30 days and go smoke free...dude...u coulda pissed yourself and saved yourself some worries...and still passed...the most that pot stays in your urine (tested and found by labs) is 90 days...and that was with a person that had 34% body fat...34 %...thats some lard right there...but the regular AVERAGE person has 20-25% body fat...and the thc can only stick for a maximum of 45 days...drinking water and other fruit drinks strips the thc away and down your toilet...stop worrying
