"What time period does a standard hair follicle test cover?
A standard hair follicle screen covers a period of approximately 90 days, but is susceptible to time variation depending on the growth rate of your hair. The hair sample is cut as close to the scalp as possible and the most recent 3.9cm (or 1.5 inches) are tested. It is possible to go back even further than 90 days since the time period is limited only by the length of the hair sample, but is standardized to a 90 day history.
What type of drugs can be detected in a standard hair test?
Cocaine (Cocaine & Benzoylecgonine), Marijuana, Opiates (Codeine, Morphine & 6-Monacteyl Morphine), Methamphetamine (Methamphetamine/Amphetamine & Ecstasy), and Phencyclidine (PCP). These five drug classes are mandated for testing by the Federal Government.
How fast does head hair grow?
Hair collected at the crown of the head grows on the average of approximately 1.3 cm (or 1/2 inch) per month. This growth rate varies among people by approximately + .2 cm per month which can create a possible time variation of up to +1 week per month.. In the rare case where no hair is collectable, complete urine/adulteration testing may be utilized.
:How effective is hair follicle testing in detecting drug usage?
In comparison to a urinalysis drug test, cocaine, PCP, opiates, and methamphetamine have proven hair analysis far more effective than urine testing in identifying low-level drug use over an extended period of time since these are normally out of the bloodstream in within 3-7 days (see drug detection times). The detection of marijuana is currently less sensitive than the other drugs in identifying low level drug users, but is considered approximately equal to urinalysis in identifying marijuana users. The detection period for hair is limited only by the length of the hair sample and is approximately 90 days for a standard screen.
Q:How do drugs get into hair?
After a substance is ingested, whether orally, smoked, snorted, or injected, metabolites are produced as the drug is processed by the human body. As these drugs and metabolites circulate in the blood stream, they enter and nourish the hair follicle and are then inserted into the hair strand." Hair Follicle Drug Testing FAQ - Hair Testing Facts
How did you take 4 or 5 pulls without knowing what you were doing?
I am not aware of anyone smoking bongs 2-3 times a week and passing a hair follicle test.
You've asked this 5 times. DrBill, our expert, answered you. I would guess you didn't like his answer (which is that you would most likely pass) because you've posted again since that question and answer. My answer is that you won't pass.
Now you have one pass and one won't pass.
