A member asked:
Scared to take a hair follicle test been clean for 8 or 9 months got my cdl and been clean ever sence is it still possible to fail the test?
A doctor has provided 1 answer
It depends.: Hair grows about 1/2 " a month. If you've been clean for 8 months, that means that no drug can be detected in the four inches of hair closest to your scalp. If your hair is shorter than 4" long, no drug will be detected in the hair specimen. Stay clean, my man. Never drive any vehicle while under the influence of alcohol, sedating meds or illicit drugs.
