I also wanna add that I took one of those cheaper at home drug tests I bought off amazon, and had a VERY VERY faint line on the T part.. and when I say faint, I mean, the only way to see it is if you look really closely.. so I dont know if it was only that faint cause it was just a cheap drug test or what.. I've heard a line is a line no matter how faint it is, but this thing was very light..
