So... I used to be a drug addict...to make a long story short...up until about a month ago, I had given up everything BUT marijuana. Last month, I gave that up to (a VERY good decision). I interviewed for a job the other day and found out that I have to take a pre-hire drug test. So to make sure that the marijuana matabolites were out of my system, I took an at home 4-panel drug test (they were out of the marijuana tests). I read the instructions and it said that a negative result would appear as a pink to red line next to the control and drug. I'm confused..I think that I had a negative on everything...but is it just a coincidence that the drug line for marijuana is a faint pink and every other line is dark pinkish red? or is there still a traceable amount of marijuana matabolites in my system? I'm new to the home testing kits..so any help is appreciated... Thank you ahead of time!
