hi all, I smoked 5 days ago (a half a 20 dub, half a blunt). I rarely smoke.. the last time I smoked before that was 2 and half months ago. I am worried because I have to take a drug test in 24days. So I took a home drug test and I tested negative, but a weak negative. I am worried I wont be clean by then and I don't know how accurate the home drug test it compared to what I will be tested with at the clinical sie I am posted at. What should I do? I am considering going on a cleanse on (cranberry juice, vinegar, and niacin and multivitamins for 3-7 days) please help. i am spazing out big time. I hardly ever smoke. I just wanted to relax, after a hard semester busting my ass. thanks guys
