Cannabinoids have a detection time of 3-45 days
Factors that an influence the detection time of Cannabinoids : Metabolism, fluid intake, tolerance, frequency of intake of substance, amount of substance, potency of substance, length of time you have been a user and amount of body fat.
2.2.1 Frequency of Intake
If you use marijuana on rare occasions, your urine may be clean of metabolites
in less than a week. There is a common and strange phenomena that occurs
with chronic users. You would expect a chronic user to have the longest
detection time and the smallest chance of passing. This is not always the
case. A chronic user with a high tolerance will eliminate drugs quicker than
an occasional user. Chronic users have tested negative after a week long
binge.
2.2.2 Amount of Body Fat
Lipid tissue also makes a huge dierence. Skinny users not only have a faster
metabolism (usually), but also lack storage for THC metabolites. Fat will
cause a lag in excretion pattern, and lead to a longer detection time.
2.2.3 Predicting Detection Period
You should now be able to understand why an individuals detection time
for THC is so unpredictable. Please don't post or e-mail a question "how
long will it take..." This is the single most frequently asked question. Many
people can't even begin to estimate a detection for their own bodys, let alone
the unseen, unknown body of a internet explorer.
There is an inaccurate program that will plot a graph of time versus percentage
of THC in your system given the days you've smoked. The program
is called CALC_THC.EXE and can be found on the internet. CALC_THC cannot
possibly be accurate because it doesn't have any way of measuring the
potentcy of the weed, and it leaves metabolism out of the equation.
2.3 Positive (dened)
50 nanograms of THC metabolites per milliliter denes a "presumptive positive"
by NIDA certied labs. This value was originally 20 ng/mL, but too
many false positives resulted. So the level was raised to 100 ng/mL to reduce
false positives. As of January 1995, the threshold was lowered back down to
50 ng/mL because drinking water would easily bring a positive below 100 ng.
Be aware that these cutos are not universally consistent. I recently heard
of a lab using a 15 ng/mL cuto! Table 2.2 details the thresholds for other
substances.
2.3.1 Passive smoke and positives
"Second hand marijuana smoke in a car can cause you to fail the next day". It is possible that second hand [marijuana] smoke will raise someone to the 50 ng/mL level; however, extreme exposure is required. For instance, a closed car full of pot smokers and a non-smoker may render the non-smoker positive for both urinalysis and the hair test, provided that they are sealed in the car for a while. The Army did a case study where volunteers were put in a room pumped full of smoke for an hour, five times
daily. Subjects started testing positive after the second day. The non-smoker
would have to take in virtually as much second hand smoke as a smoker
inhales. Non-smokers are safe in a ventilated area, as long as they don't get
a hair test. According to Clinton, simply blowing crack smoke on ones hair
may cause a positive hair test. Second hand pot smoke doesn't affect the
hair test results as much as crack smoke does mainly because exhaled smoke
contains no THC. The only pot smoke that contains THC is the smoke that
hasn't entered the lungs.
2.4 Decreasing detection times
Increasing metabolism is probably the most effective way to decrease the
time period that drugs can be detected in your system. Metabolism can be
inuenced by physical activity, diet, and drugs.
2.4.1 Physical Activity
Physical activity can increase your metabolic rate as much as two thousand
percent! Nothing beats proper training taken to an extreme.
2.4.2 Diet
A high calorie diet is the next best way to increase metabolism. Consuming
mass quantities of high calorie food will increase metabolic rate by up to
10 percent. On the contrary, a malnutritious (light) diet could lower your
metabolism by 10 percent.
2.4.3 Using Drugs to Reduce Detection Times
Amphetamines will also increase metabolism. Unfortunately, labs usually
test for speed, and could get you into trouble.
Things Tested to Detect Counter Measures:
Laboratories know how easy it is to tamper with urine samples and alter the
results. Labs often test to Find out if the sample is legitimate.
6.1 Color
If a urine sample looks clear, the lab will suspect that it is watered down.
They cannot report it as positive, but they may reject the sample and inform
your employer that you tried to beat the test. If this happens, the sample
might as well be positive, because you won't get hired. Take vitamin B
complex to color your urine yellow.
6.2 Temperature
Urine should be between 91 and 97 degrees. NIDA certified labs will verify
temperature. If the sample is out of the accepted temperature range, they
will suspect you added water to the cup, or used substitution. Disposable
pocket hand warmers (sold in department stores) will keep a urine sample
warm, provided that the urine is in a condom or douche bag.
6.3 Creatinine
Creatinine is a substance produced by vertebrates, and it shows up in urine. If
someone substitutes their urine with something other than urine, like Mountain
Dew, they will test negative for drugs. However the testee will most
likely not get away with it because Mountain Dew contains zero creatinine,
and labs test creatinine levels to ensure that the sample is valid. Creatinine
levels drop below normal when people dilute their urine. This tests to ensure
that the subject did not drink unusual amounts of water. An *accurate* creatinine
"clearance" test would require a urine and blood test 24 hours before
the drug test to determine the normal creatinine level for that individual.
This is almost never done. You should still be cautious because they do often
use the inaccurate method of comparing your creatinine level during the
drug test to an average. People who are drug-free sometimes lose their jobs
for having too low of a creatinine level.
6.3.1 How to Increase Creatinine Levels
Eating foods rich in protein like red meat will slightly increase creatinine
levels. There is no significant variation between vegetarians and armavors,
so the effect protein has is little. Sexual activity also raises creatinine levels.
I doubt sexual activity influences creatinine level with much significance.
However, a vegetarian that does not have much sex should be concerned.
6.4 pH
pH is often changed when people spike their sample with household products.
Use caution when doping urine, pH is usually tested.
THC is fat soluble, and it gets stored in your fat cells. Cleaning it out of
your lipid tissue is very dicult. Many herbal products claim to clean out
your system, yet they do nothing to remove THC byproducts from fat cells.
A study was done in Germany in 1993 on 50 of the most common herbs used
by people trying to pass the test. All 50 herbs failed to cause a negative.
Unfortunately, this rumor will not die. Goldenseal is useless; yet it's the
most common thing for people to use. The only way to extract THC from
fat cells is to exercise. Fat cells secrete fat with THC metabolites at
a constant rate, regardless of what herbs you consume. You may be able
to temporarily rid THC metabolites from your bloodstream, or dilute your
fluids to yield a larger urine/THC ratio, but your bloodstream will continue
collecting THC metabolites from fat. Your urine will continue collecting
THC metabolites from your bloodstream.
7.1 Dilution
Hyper saturating your body with fluids will dilute metabolites possibly below
the 50 ng/mL threshold, depending on your metabolism. Be aware that
creatinine levels are often tested, and will show that the sample has been
diluted. Diluting your sample will also produce clear urine, with virtually
no yellow color. They will assume that you've diluted your sample, and they
may reject your sample on the basis of color alone. It's only necessary to
start drinking just before the test. Those who drown themselves in fluid days
before a test are only causing unnecessary discomfort. Those who stay up
all night drinking don't have any better chance than one who drinks heavily
first thing in the morning. Get up early if the test is early, but don't lose
sleep over a test that is given in the daytime.
7.2 Water
Drink at least eight hefty glasses of fluid (preferably water) just prior to the
test. Many people start drinking water several days before the test; which
is useless. Water does *not* clean any THC metabolites out of your system
because THC is not water soluble. Water only dilutes urine temporarily. Do
not over do it; you can get water intoxication. People can actually overdose
and even die from water intoxication. It's very hard to do, and you'll vomit
before anything gets serious.
