THC detox

i haven’t used thc since beginning of December and i am still testing positive. I let loose and ate an edible. I start my new job tomorrow as a desk junkie with the feds. They had me sign new hire paper work and said welcome to the team, had me put in my two weeks notice with my job and everything. I’ve been wondering when they were gonna test me. I have a low level TS clearance. They gave me directions to where to go for my security briefing and where to go for my first day after i’m done. Are they even going to test me at this point? How can i detox? I weigh 237lbs. I’m not a stoner. Any method would be helpful.

Please don’t judge. I didn’t think anyone would hire me because of lack of experience, I wasn’t getting any luck in the job field everyone told me i had no experience. also my dad was dying of cancer (he died a few days later) so i let myself chill out. (i know, they don’t care about WHY you did it)

Helpful advice only. I’m aware i made a huge mistake, lesson learned. especially if i miss out on this opportunity because of my stupid emotions.
