How far does the testing for a hair follicle and nail drug test go back? I am getting conflicting answers on both tests. I have been told 90-120 days or longer for hair follicle depending on length of hair and up to 1 1/2-2 1/2 years for nail testing.

How far does the testing for a hair follicle and nail drug test go back? I am getting conflicting answers on both tests. I have been told 90-120 days or longer for hair follicle depending on length of hair and up to 1 1/2-2 1/2 years for nail testing.

How long does cocaine come out of a hair follicle and how far back do applicants for an rn  get tested ?

How far BACK?: Maybe I'm missing something but I can't for the life of me figure out what "how far back do applicants for an RN get tested?" means? Unless you're Marty McFly then, nobody can be tested for ANYTHING required by a job application process any further BACK than the 1st day an application for a job requiring drug screening is made. Otherwise, you'd be testing people just THINKING about a certain job? ...Read more

how long will pot show up on a hair follicle test? I smoked once or twice a week for a couple months. I stopped 3 months ago.

 how long will pot show up on a hair follicle test? I smoked once or twice a week for a couple months. I stopped 3 months ago.

"POT": The standard detection window for the hair test is 90 days. Because hair grows about 1.5 inches (3.8 cm) in 90 days, hairs with a length of about 1.5 inches (3.8 cm) are targeted for cutting. Longer hairs will give a longer window of detection. ...Read more
