OK, so I have a drug test on Friday for a job oppurtunity. I had two hits of weed two weeks ago friday. the week before that I had some too. But i have not had any since and I have been drinking tons of water. To be safe I bought an at home drug test today and i just did it. two lines meant positive for pot and i had one line and another very faint but still present line. this means i tested positive for marijuanna i think (because there was a line even though it was faint) and I dont know what to do. If I keep drinking a lot of water is it possible for me to pass my drug test on friday?
