Just recently got my urine test results and it was too diluted(but negative) for the conclusion to be valid so recently I received a call from my employers saying that they'll have to make me retake the drug test through my hair follicle next week on Thursday, Dec. 8th. I'm freaking out right now because I've had one very light hit of weed about a month ago(On Nov. 6th) and between 3-4 casual/light hits a little over 3 months ago(on a Labor Day weekend on September) and I've been told by many people that a hair test can detect up to 90 days or possibly over a year depending if they decided to get a sample from my body hair instead of my head hair.
