How far dorsum can the pilus follicle exam go to observe drug utilize?

The pilus follicle drug exam, when using the standard 1.5 inches of pilus, can observe previous drug utilize up to 3 months. If a longer piece of hair is selected, the drug test results can get back much farther (in fact, years further) to detect drug use.

We tin test underarm, leg, or breast hair. Occasionally, bristles hair can exist used equally well. And, no, nosotros cannot get the hair from whatsoever other place on your body other than those previously mentioned!

Does trunk hair hold drug balance longer than caput pilus?

At that place is much debate nearly the stride at which trunk pilus grows. Many people are concerned that an inch and a half of body hair will retain drug residual for a much longer period if the body hair grows much slower than the head hair.

The reality is that body hair and head hair grow at the same rate. The difference is that torso pilus tends to cease growing at a shorter maximum length. In both head and body, new hair replaces dormant strands and pushes them out.

Think about how you naturally shed pilus. Shedding happens because a new pilus pushed out the old one, which stopped growing and became dormant. When a hair is dormant (i.due east., non growing), no new drug deposits can get into it. Information technology can stay at that place ane to 4 months, so in theory, head OR body hair tin reveal drugs that get back further than ninety days, depending on the person. Nevertheless, only 10 to 15 per centum of your strands are in this fallow stage, so the risk is minimal.

On the other manus, in that location are many anecdotes (and a few labs) that report that body pilus tin can pick up drugs for up to 12 months. Although there are no scientific studies that have shown this conclusively, yous'd be wise to consider it when thinking most how to interpret the results.

The bottom line is: the 90-24-hour interval mark is an educated approximate, just in that location is no calendar in your hair. Accordingly, a positive effect doesn't signal the dates that the drugs were used. In conclusion, your pilus retains your drug use history, simply not in the same fashion that, say, an internet browser retains your search history.

What if I have no head or torso hair?

Sometimes Wellness Street gets calls from people who desire a hair drug test, but they have no head or trunk hair. A guy recently told us, "I shave from head to toe." Well, how did he recall we were going to perform the examination? Nosotros are however trying to figure that one out! The lesser line: no hair means you tin't get a hair drug test.

Does the pilus follicle drug test work if I'thou an infrequent user?

Yeah, the pilus follicle drug test works regardless of how often ane uses drugs. The frequency of drug use does not impact test results. Information technology is the period in which the user used drugs that determines the effect of the pilus follicle drug test. Whether a person used one time or 50 times in a 3 month period, the hair follicle drug exam will signal that drug use.

Tin I "cleanse" my hair of drugs so I will pass the hair follicle drug examination?

Opposite to pop belief, in that location is no style to cleanse your hair of any drug substance. Drugs enter your bloodstream and thus, become embedded in your hair, and it stays there until that hair is removed from your body.

Can secondhand smoke make me fail a pilus follicle drug exam?
