Passing drug test??

I drink lots of water and tea which has lots of antioxidants and for some reason I feel like that’s a good thing. But again, I drink a lot, for example when I go to my fridge to fill up a large “McDonald’s large” cup of water I drink one immediately then refill it to drink before the ice melts. I’ll do this maybe every hour or two. Tea, depending on how sweet, I may bang out a gallon a day if it’s not super sweet. I’ve never failed a piss test even smoking clear up until pissing. Then again, let my old p.o. tell it, I’d “recently” had cocaine in my system when I legit hadn’t EVER touched the stuff outside looking at someone else’s shit in a bag years prior... but i did pass a lab Corp test once while smoking earlier that day, and one time for a job I really wanted I quit smoking for about three weeks when the interview came early and I passed then.
