Any pink line at all, no matter how dark or light is passing. A light pink line in the "drug" window for THC is normal for a negative result and is no indication of how concentrated THC metabolites are in your system, only that it is below the cut off level indicated on the test.
deandavidmartin Reviewed by deandavidmartin on . Test tomorrow..just need advice I've read a lot on this site today but just want to ask to see what you all think. I haven't smoked for 73 days (May 28 was last time). I had smoked everyday for about 2.5 years. I took a First Check THC test this morning with 2nd void and I take my test tomorrow morning for a new job so I don't have time to do a 1st void test again. I figured I could sub if I have to but would rather use my own. I got a lighter pink line than the Control but it was a definite pink line. I am a woman, 5'5 Rating: 5
