Consider the risks of diluting the sample. Dilution is the process of reducing the concentration of drug or drug metabolites in the sample in order to Pass the Drug Test. This is accomplished by adding fluid to the sample. Diluting a sample will lower the specific gravity and creatinine level (creatine is used by muscles and creates a waste product called creatinine). Drug testing laboratories all routinely test samples to detect dilution. If you decide to go this route anyway, be sure to use warm water, as the temperature of the sample is recorded. Most facilities will put you in a room with no sink, and where the toilet water is tinted.
- Internal dilution or
"flushing". Many people assume that
drinking excessive amounts of water will
accomplish a negative result. However is
it dangerous (people have died from
water intoxication) it is also risky
because colorless urine arouses
suspicion, possibly flagging the sample
and causing them to run the sample at a
lower CONFIRMATION level of 15 ng/mL (15
nanograms per milliliter) instead of a
STANDARD test screen level of 50 ng/mL
(this example is of THC). When the UA is
run before the screen it will read that
the specific gravity is low and it will
be flagged, this also will cause a lower
level test to be run
Substitute the sample.
Substitution is a method that involves
substituting your urine with that of
another persons or a synthetic sample.
Synthetic urine comes in two basic
forms, the liquid type found in smoke
shops that is similar to what is used to
calibrate lab equipment or vials of a
powdered concentrate that can be added
to a few ounces of warm water. Both are
kept in a delivery devise
with a temperature meter. This method
works on every employment urine test
(provided some conditions are met such
as controlling the temperature (92 -100)
and delivering the sample in 4 minutes
or less). You can guarantee it stays to
body temperature if you use something
like "The Strap" which can be found on
ebay. It keeps synthetics to body
temperature and keeps it concealed under
clothing. A liquid crystal thermometer
with 2 degree offset like the ones used
on the collection cups is ideal and a
properly sized organic warmer as a
insulating source as it is the body that
is the regulator. Some labs are now
testing for synthetic urine. For your
legal protection it is critical that you
do not use this method for any
government tests including military,
civil service, and especially probation.
- The liquid premixed urine has a
couple of drawbacks as it doesn't
have a head or small layer of
bubbles on the surface and it has no
smell. Powdered synthetic urine
does. Many labs and collection sites
will reject your specimen if they
suspect it is synthetic and ask you
to urinate under direct observation.
- You can substitute someone
else's urine. You will want to test
it with a reagent panel strip
here Collect the
urine fresh and keep it in a sealed,
refrigerated container, and use
within 48Hrs, as urine will darken
and bacteria will grow. You can also
freeze the urine for longer storage.
If deterioration becomes noticeable
the lab may suspect something. A UTI
or Urinary Tract Infection will be
suspected if a micro UA is run as
stale urine becomes like ammonia and
the pH will change.
- standard employment drug tests do not determine male or female, pregnancy, or age.

- Understand how the
hair testing process works. We'll
use marijuana for our example since
marijuana drug testing is by far and
away the most popular test. When
marijuana (THC) metabolites are in the
blood, they'll end up in the blood
vessels, including those in the head,
and get filtered through the hair.
In basic terms, at least, this is how
hair drug testing comes about. The
marijuana THC metabolites will remain in
the hair as a permanent record of drug
use for months. A hair drug test
involves cutting 50-80 strands of hair
from the base typically at the crown of
the head. Minimum length of 1 inch is
necessary or body hair such as face
chest or underarm hair can be used. Hair
drug testing can go back months, showing
the toxins a person may have used in a
time-line fashion. Masking hair is not
realistic as the sample is washed to
remove left in products or external
contamination such as second hand smoke.
- Know what to expect
in the test. Hair Collection
- Testing requires a swatch of
hair about one eighth of an inch in
diameter and an inch to an inch and
a half long, cut close to the scalp
and at the crown of the head if
present. If the donor has no head
hair or 1/2 inch or shorter the
collector may use chest, underarm,
leg, or face hair in that order of
- Find an appropriate spot for
hair collection, then twist a bundle
of hair making sure the tightly
twisted hair is more than 1/4 inch
in diameter. This is almost always
done in middle back of head
- While holding the tightly
twisted hair in one hand, spread
open the hair collection tube with
the other hand, then enclose the
twisted hair in the collection tube
as close to the donor's scalp as
- Place the twist tie around the
hair below the plastic collection
tube. This keeps the hair intact
during shipping and also indicates
the root end.
- Cut the hair bundle as close to
the scalp as possible. Do not remove
the collection tube from the cut
- Return the collection tube
holding the hair to its original
position in the hair collection tube
holder. Do not remove the twist tie.
- Testing requires a swatch of hair about one eighth of an inch in diameter and an inch to an inch and a half long, cut close to the scalp and at the crown of the head if present. If the donor has no head hair or 1/2 inch or shorter the collector may use chest, underarm, leg, or face hair in that order of preference.
Lower toxin levels in
your hair. This can be much harder
if cocaine or synthetic drugs are used
by dark haired people as it is the
melanin (hair color) that is the carrier
as apposed to keratin (hair) in a THC
screen. So repeated use in dark hair
people is almost impossible to reduce
below detectable levels.
- Regular smokers should use a
clarifying shampoo regularly to
remove toxins that are excreted
daily from scalp.

Saliva / Oral fluid-based screen
Saliva / oral fluid-based drug tests can generally detect use during the previous few days. Saliva or oral fluid based drug tests are becoming more prevalent because of their convenience, low cost and the recent adaptation of the FDA approved Intercept test can be given in-house on the job for pre-employment and random screenings, random, post-accident, reasonable suspicion, or return-to-duty testing.
- Know the detection
times. Detection in saliva tests
begins immediately upon use:
- Marijuana and hashish (THC): An
hour after ingestion, and up to 24
hours depending on use.
- Cocaine (including crack): From
time of ingestion up to 2 to 3 days.
- Opiates: From time of ingestion
up to 2 to 3 days
- Methamphetamine and ecstasy (MDMA,
"crank," "ice"): From time of
ingestion up to 2 to 3 days.
- Benzodiazepines: From time of
ingestion up to 2 to 3 days
- Marijuana and hashish (THC): An hour after ingestion, and up to 24 hours depending on use.
- Try to avoid the test.
If one is being tested and has used in
the past 3 days you will need to
overcome the saliva collection. To do
this you will have to avoid submitting
saliva and perform the steps requested
of you by the instructor.
When instructed to place
the collection pad between the lower
cheek and gums and gently rub the pad
back and forth along the gum line until
the pad is moist, you will fake this
movement and rub pad on teeth.
- Once moist, you are supposed to leave collection pad between cheek and gums for a full two (2) minutes (again hold between teeth).
