Are my worries warranted?

[FakeBoobsRule]

Anywhoo, I have a job interview(which most def. piss-tests) In April. Late April, with the possibility of a few week postponement. Now, I have not smoked in two weeks, and have been drinking lots of fluids, and started working out. I am particularly slim and pretty short, and my metabolism is really fast. Come early April, I am going to start running and playing some basketball, you know, your basic cardio stuff.

The massive fluid intake well before the test is useless. THC is not water soluble. The cardio is good. The home test you find in drug stores or online are fairly accurate, around 95%. The main thing is they need to be properly stored and that is hard to figure out.

You should be good by the end of this month if you're keeping it up.

You can't know that for sure. Lucky for the OP he wants to use a home test to make sure.
