calm down, bra. all you have to do is drink water and you'll be fine. i'm going to give you two scenarios which will see you through.
1. eliminate sodas from your diet and make water the foundation of all fluids you consume, next, exercise or involve yourself in activity that makes you have a good sweat, daily.
2. take a multivitamin, between 20 minutes to a hour before being tested, preferably one with over 100% of the daily values-your body only uses up to 100% of the vitamins and minerals and the excess is considered waste which is urinated out which masks thc.
this technique is a must and should always be coupled with the previous two when taking a urine test-drink enough water prior to taking a urinalysis to make your urine clear, i repeat never take a piss test until you piss yourself clear.
if you're subject to mouth swabs holla at me, i'll teach you how to beat them also.
oh, by the way i've been on papers since 03', never had a dirty, never stopped smoking, i even smoked the same day i knew i was taking a piss and passed it using these techniques(purple haze just came out and i couldn't control myself). i can break down how these techniques work if you need me to explain further, but, you'll definitely pass if you follow the simple instructions i guarantee. good luck
