Freidrich_Thanatos's journey

I recently passed a job interview and was excited to receive a job offer soon. However, I've been consuming 420mg edibles daily for the past two weeks, sometimes taking up to three at a time. I just learned that there will be a drug screening within 48 hours after I receive and sign the offer, which could be as early as next Tuesday. I'm really worried about testing positive for THC. I've seen mixed advice online; some people suggest being upfront with the hiring manager about my usage, while others say that some companies don't screen for marijuana at all. I'm unsure of what to do next and how this might affect my chances of getting the job.
