WASH YOURSELF OUT: The general strategy for passing urine tests is to increase your fluid intake and urine flow so as to dilute the concentration of drugs in the sample below the threshold of detection. An hour or two before the test, you should fill your bladder with fluids - as much as you can drink. Water is fine - contrary to popular rumor, there is NO evidence that goldenseal, vinegar, niacin, or vitamin C help. However, high-dosage aspirin may reduce the sensitivity of the EMIT urine test for pot (only). Many people wash themselves out for several days in advance by drinking a lot and exercising, but there is no reason to think this is useful. In no case should you give your first urine of the morning, since drug metabolites tend to build up during your sleep.
While you're loading up on water before the test, you may also want to take a large dose (50-100 milligrams) of vitamin B-2, available in B-complex multivitamins. The purpose of this is to color your urine yellow, since otherwise you are likely to produce clear, watery urine, which makes some collectors suspicious (contrary to rumor, vitamin C won't help). In rare instances, some labs will reject a sample for being too watery; in this case, however, they will typically give you a second chance. Wait until your test results have been confirmed before indulging in compromising behavior.
You can boost your fluid output by taking diuretics, which stimulate urination. Weak diuretics include coffee, cranberry juice, certain health food products and over-the-counter pills for pre-menstrual water retention.
If you're taking the test on very short notice, you may wish to resort to more potent diuretics, which are widely prescribed to treat high blood pressure. Although strong diuretics, such as furosemide (Lasix®), are available only on prescription in the U.S., they can be had over-the-counter in Mexico and other foreign countries. Beware that they can be dangerous for certain persons, such as diabetics or pregnant women, and can cause problems if taken over extended periods. Diuretics can be detected in urine, but are rarely checked except for athletes. The following regime has been suggested by a former army drug testing officer (Robert Freeman, "How to 'Beat' a Drug Test," High Times, Aug. 198: Take an 80-milligram dose of Lasix; take a hefty drink of water; piss two or three times, then take the test. If you're lucky and didn't smoke too much pot, a good washout may get you past a test on a couple days' notice. However, regular smokers should allow at least a week or two if at all possible.
DRUG SCREENS? It has been suggested that the ingestion of certain substances might alter body chemistry so as to disguise drug use. Although many products are currently being marketed as drug screens in head shops, High Times ads, etc., few have any solid scientific basis. Activated charcoal, a common detoxifier, might help lower metabolite levels a bit in long-term users if taken over the course of some days or weeks. It has been suggested on theoretical grounds that lecithin, a food emulsifier, might also be useful if taken over extended periods, but this hasn't been proven. A number of high-priced herbal teas and powders are promoted as urine cleansers, with no good medical rationale. While some users have reported remarkable success with them, many others have not. Independent experiments suggest that it may be water dilution, not the screen itself, that accounts for success.
TAMPERING: While urine dilution is useful, it isn't 100% reliable, especially for heavy daily users. Another tack used by some people is to tamper with the sample by adding adulterants or substituting clean urine for their own. Ethical issues aside, tampering is risky since subjects may be observed or made to disrobe beforehand, and cheating isn't forgiven. For the adventurous, Abbie Hoffman's book Steal This Urine Test has full instructions on how to rig yourself up with a plastic bag to substitute clean urine. You can buy clean, dehydrated urine from Byrd Labs. Beware however that labs check to make sure the temperature of urine samples is right (around 91-97).
Another trick to foil the test is to spike the sample with an adulterant. This approach should be used only as a last resort, since any adulterant can be chemically detected if labs take the trouble to do so. A number of adulterants cause negatives on the commonly used EMIT test, but not necessarily other tests. In an emergency, you might fool an EMIT test by adding a few drops of Visine® to the sample. Other common adulterants include detergent, bleach, salt, and the cleaning solution glutaraldahyde, but most of these are easily detected by smell or visual inspection. A host of commercial adulterants are on the market (for advertisements, see High Times). Among the more popular are Klear® and Whizzies®. No additive is 100% reliable, and all involve a substantial risk of detection. Many drug testing companies claim to test for adulterants, though it isn't clear how carefully.
Many drug testing aids are advertised with money-back guarantees if you test positive. BEWARE: guarantees do not assure good test results! Vendors often exaggerate product reliability and ignore customer complaints.
http://www.onlinepot.org/misc/pisstests.htmIm not trying to start anything but I cant agree with this i passed my probation tests 100 percent with just water for 3 years(36 months).Dipstick test or sent to the lab.
There is no way to actually do a on the spot test to see if one is under the influence, this is another contribution to the reason why marijuana is still illegal.
I disagree. A blood test can test for THC impairment.
What would show up on a blood test that would show you were intoxicated at the time of the test and not just the fact that you have thc in your system from heavily smoking for the past couple of days (i.e. you werent high at the time of the test) ?
