So I wasn't smoking frequently everyday but the times that I did I guess it was alotta weed but I hadn't smoked for exactly a month when I took this drug test and I still failed. I have absolutely NO idea how. I didn't smoke at all except some synthetic weed and I was regularly drinking a lotta water and working out. I even took some niacin. Anybody know how I could've possibly failed????? The only things I could think of is my boyfriend blowing smoke in my face and kissing him after he had smoked but I dont think that would've made me fail.
