Hey everyone, I need peace of mind honestly, I know there is no 100% answer on here, but past experience means a lot to me so please share. Here is my situation: I smoked mostly Kush daily (blunts and bowls) for about 4 months straight. About a gram a day. I finished college and knew I had to get a job, so I quit and my last day that I smoked was July 31. I got a great offer from a corporation who uses LabCorp for the drug screening. I got offered the position on the August 20th but didn't have to take the drug test until tomorrow/today August 31st. For the first two weeks after I stopped smoking, I used Niacin 500mg a day. I then bought some test strips and passed (very faint 2nd line)(after 14 days). After the first two weeks I stopped using Niacin because it makes you break out bad. On August 23rd I bought the Marijuana test from Walgreen's and was negative as well. I have also lost around 10 pounds and run about 2 miles twice a week. I am now 5'10 175 pounds and have about 22% body fat. I spent all day today(day before my test) working out, drinking green tea and cranberry juice, took more niacin, and drinking water. I also have average metabolism. I know I will pass a 50n/g urine test with flying colors, but I am unsure if my company is testing harder. It will be exactly 30 days tomorrow of staying clean. I plan on going for a long run in the morning and then taking my test around 3pm. What else can you suggest for me to do in the morning? What can you tell me about LabCorp? Do you think I would pass a 15n/g test? Please be 100% brutally honest. Thank you everyone for your feedback!
