Hello 21 year old 6"3 215lbs male here. i smoked on february 4th and my drug test is on march 5th. it was the only time i've smoked in the past six months and i dont know why im freaking out so much but i USED to be a veryyyyy heavy smoker but i went clean for over half a year. ive been drinking water all month tons of it. im worried of drinking too much and diluting my pee for the test but i want to make sure i clean my system before i take this drug test. once again, i only smoked one time and it was almost a month ago. should i be good? if not what are some ways i can make MY REAL pee clean? dont want to fake this test. i want vitamin tips drink tips without detox fake crap. its a walmart drug test.
