Thank you, FakeBoobs and ghosty, for your inputs.

As I mentioned on the original post, I did purchase a home test kit from drug store (couldn't order one online on such short notice) and just tested myself with the first void of the day.

This was the first check test where you dispense 3 drops over the sample well, with two lines in the control window and the THC window being a negative result for marijuana detection.

A quick excerpt from the manual:

'The line next to THC in the Test window may be lighter or darker than the line in the Control window. The presence of any line next to THC is considered negative. Do not attempt to interpret the result based on how light, dark, or faint the line may appear.'

Now, my THC line was definitely on the lighter side but I could see the line clearly. So according to the booklet, I passed the test!!!

I can rest easy now, already called GNC to make sure I can return the STRIP drink...and take the test tomorrow instead of today so I can at least drink some water/cranberry juice throughout the day and in the morning to be safe.

Thanks for all the great info on this board! I really, really am appreciated of how much I've learned over such a short amount of time. Man...looks like I quit just in the nick of time!

Now time to pass the real deal...LOL
