I took a walgreens home drug test and had a very faint second line. two lines means its negative, one line (the top line is positive for THC).
The top line is the Control line (C). A line present here indicates that the test kit is performing properly. If no Control line is present (after 5 min), it means the test kit is defective or the testing wasnt administered correctly. Either way, re-do the test with another kit.

In order for the urine sample to test positive, the Test area (T) must remain completely blank.

Your test result is a negative. I see a line there in the Test area. Even though its faint, its still a negative.
