If you pass a first check test first thing in the morning, is it a guarantee that you will pass a pre-employment drug screen on any day from then on? The line is a little faint, but it is a line. Picture below.

Will exercising between now and the drug test alter the results?
Would one be fine to take a drug test in a week and pass for sure?

I've researched a lot but I'd really love some reassurance.
Thanks
