How Long is the Detection Period for a Hair Drug Test?
A simple way to test for whether or not an individual has been using drugs is to administer a hair drug test. This is one of the best ways, in fact, to detect drug usage in a person because it is fairly non-evasive and is always fool proof, and takes place using a part of the body that everyone has. Hair does not necessarily need to be taken from the head; rather, it can be taken from anywhere on the body.
The science behind the hair test
Basically, when any substance is taken into the body, particularly drugs, small elements make their way into the blood stream. This, of course, is what causes the “high” of the drug. Whatever ends up in your blood, from nutritive elements to narcotics, eventually is processed to the parts of your body that grow on a regular basis, namely the hair and the fingernails. The problem with testing for drugs using fingernail clippings is that the elements in the blood are turned into keratin during metabolism and therefore are no longer present in their individual parts. Hair, however, retains the memory and the atomic structure of whatever has been ingested and keeps a record, much as the rings on a tree do.
The length of time for which the test is effective
The effective range for a drug test in an individual’s hair sample will differ according to each individual. In fact, drug usage can be detected as long as that particular hair has been growing, the only time period that may be missed by such a test is a narcotic that has been ingested just prior to the test; usually a period between two to five days. After this time, the drug will start to show up in hair samples.
Standard information on hair drug tests say that they are effective for around ninety days, or three months, and right up to 120 days (four months). This, of course, is based on the average growth rate of a human hair follicle. The idea here is that after that period of time has elapsed, the average person is likely to get a haircut that will result in the loss of the part of the hair follicle that grew during drug usage.
Just as an individual may keep a permanent record of their drug usage by never cutting their hair, so can short hair or a shaved head erase any hair follicle records of drug usage. This need not foil testers, however, as any hair on the body will keep this record.About the author: Urine drug screening tests for the detection of Adulteration are now available online.

I’ve gotten a lotta different answers but I get drug tested randomly-monthly for school and I just wanted to know how long before school I need to stop. Like 1 or 2 weeks?? I heard saliva tests have a really short detection time. Please help.

Actually the saliva testing is one of the most effective and easy ways to determine when, and how long ago you have used marijuanna.
If you are randomly tested for drugs, why would you risk getting punished so severly? Just quit using and enjoy a good life at school.

what things can I do to pass a saliva drug test?
ANSWER:
Saliva tests are able to detect use within the past few days.
Detection is available immediately upon use and usually
detection period for Cannabis :
Up to 14 to 24 hours (prime detection range for THC is normally up to 24 hours, but detection up to 48 hours has been noted, so 72 hours should be considered quite safe).
( For example detection period by Urine test for
Cannabis (Single Use) 2-3 days
Cannabis (Habitual Use) Up to 12 weeks)
So…The best way to pass saliva test is simply by abstinence from weed 3-4 days before your test.
QUESTION:
What methods people usually use to pass a saliva drug test ?
I’m curious because i know about the urine test but know nothing about the saliva test… I did a search and most sites claim the detection time is shorter than the urine test. Any known working tricks ? Something to chew on or rinse my mouth with ? Thanks…
ANSWER:
For most drugs it is very much shorter!. I am guessing you are talking about THC. Just a 12 hour wait should get it out of your system. But thats why saliva tests are uncommon. Expect them to check your urine,blood,or hair!
QUESTION:
Up to how long can marijuana be detected in your saliva?
I last smoked Saturday evening and I had a saliva drug test done today (Monday) around 11:30 am. I’ve read many different detection times. The one that appeared most was between 12-24 hrs. I weigh about 115 lbs and I have very high metabolism. I am a regular user of marijuana though I’ve also read that how often someone uses isn’t relevant in saliva testing.
ANSWER:
ive personally smoked at 8am, taken a saliva test at 3pm and passed, there are a bunch of factors, but rule of thumb is listerine does wonders for helping a saliva test, also i dont think weight matters, im 265 pounds and i passed my test, saliva tests are notorious
