Cocaine And Marijuana Hair Follicle Drug Test Results (Page 2)

Updated

I took a hair follicle drug test and 1200 was the level for cocaine and marijuana. Can they determine how long ago the drug was used?

I would say that will never show up on a hair drug test. Also you might want to be careful because the heroin gangs are lacing cocaine with Fentanyl, which can kill on just the first use.

readytopass, It all depends on what the confirmation cutoff level is of the lab that was doing the testing. The lab I partner with has a .10 pg/mg GC/MS confirmation cutoff level.

For THC, and just THC, the positive number does not correlate to the amount used, like medium or heavy use. When I send out results if the THC is positive I put "Qualitative- amount does not correlate to usage"

I've been clean from cocaine for 1 month but I messed up and took 2 small doses 3 days ago. Will I come out to be positive for my hair follicle in 4 days?

A hair drug test is meant to show consistent use over time. A 1.5 inch sample, cut at the scalp line, will go back 90 days. If you only have been clean for 1 month and the test goes back 3 months than most likely you are going to be positive on a hair test. The "2 small doses 3 days ago" aren't going to make a difference because it take the hair about 5-10 days to grow above the scalp so it can be cut for a hair test.

Hey guys, need some help to put my mind at ease...

I last dosed on June 21st and before that I was a heavily dosing during my twenties and since January 2017 I was only dosing occasionally. I had a hair test on the 23rd of October for an oil company, so around 4 months since I stopped and they took around 2 inches of hair.

On the 28th of July I shaved my head to 3/8inch.

Will I test negative?

Please help.

Hi Hair guy. My husband just took a hair follicle test and it came back positive for THC at .19. The cut off was .10. Is this a very minuscule amount? He hardly smoked prior to completely quitting and it's been a couple of months we think. How much over is that and how long do you think it will take to test negative?

Hey, I might be getting tested this week for hair. They usually only look for marijuana because thats what started all of it. I haven't smoked in over 90 days, but did taste a minimal amount of coke too. Just enough to numb my gum and I'm wondering if it could show up? What do I do to get my hair clean if so?
