Hello everyone,
My company has recently started testing its employees using the hair follicle/ strand drug testing method. I used marijuana approximately 1year and 5 months ago, and have not used or been around it ever since. I recently too a urinalysis and passed that a couple of weeks ago. My question is "How long does marijuana stay in ones hair/ hair follicle"? And, if my employer takes sample from my underarm hair will it show up as a positive, since underarm hair grows slower than head hair? Please be honest with your answers and if anyone knows the drug detection timeframe for both head and underarm hair, kindly post it. Thanks in advance!

No problem with test, you will pass

Do not waste your money on Cleansing shampoos from companies like Passyourdrugtest.com, they DON'T work and A-Z Enterprises (owner of passyourdrugtest.com) will not refund your money even though their website clearly offers a money-back guarantee. Most hair follicle test only go back 3 months (first 1.5 inches of hair from the scalp) due to the cost involved. According to most sites, the usage is 1 times in 3 months to be marginal on the hair test limits. If you have not smoked in over a year, it is unlikely it will show up on a hair follicle test. While toxins stay in the hair until it is cut off, your hair would have to be 7-8 inches long to still be detected (hair grows at appx 1/2 inch per month).
