peace out peeps and keep them fat

Phatboy that didn't make any sense. The instant tests use an immunoassay that reacts to drug metabolites and not vitamins. Then a lab that would use GC/MS to verify any positives whether from an instant test or a sample that is sent to the lab right off the bat would not look for vitamins. Even lab tests use a type of immunoassay that reacts with drug metabolites but it is not in the form of a stick with lines.

Stoned, the reason why that line might not be as dark as other lines is because when you pass a test, it doesn't always mean you have none of the drug you are testing for in your system. There are cutoff levels to keep false positives down. The usual cutoff for THC is 50 ng/ml on immunoassay, in which they measure for 31 different metabolites (GC/MS is usually 15 ng/ml looking only for THC-COOH). If the line appeared showing a negative result, it only means you are below 50 ng/ml. You could be at 0 ng/m but that is still below 50. You could be at 25 ng/ml but that is still below 50 and still a pass. You may have some THC metabolites but not enough to fail.
