Dale Gieringer, Ph. While NORML strongly opposes drug use on the job, we think no one should be forced to submit to urine testing, especially for marijuana. Aside from launching a legal challenge, your best defense against urine testing is to be clean.
Unfortunately, this may be difficult since urine tests may detect marijuana days after an occasional use, weeks in regular users, and weeks in multiple daily users. If you are on the job market, it is prudent to expect being tested and avoid marijuana. However, recognizing that many of you may face drug testing on short notice, we offer the following advice for emergencies with our best wishes but no promises!
Although urine tests are far from infallible, it is difficult to challenge positive test. The standard procedure is to first screen the samples with an immunoassay test e. The sensitivity of the test is Will diluted urine pass a drug test by the concentration of metabolites it is set to detect: for the Dept.
No substance is known to produce a false positive for marijuana. It used to be that ibuprofen Advil, Motrin, Nuprin interfered with the marijuana test, but this problem has been fixed. 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. 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 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. 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. However, regular smokers should allow at least a week or two if at all possible. 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 Timesetc. 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. A 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 s for success. Another tack used by some people is to tamper with the sample by adding adulterants or substituting clean urine for their own. You can buy clean, dehydrated urine from Byrd Labs. 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 of adulterants cause negatives on the commonly used EMIT test, but not necessarily other tests. 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. Many drug testing aids are advertised with money-back guarantees if you test positive. Vendors often exaggerate product reliability and ignore customer complaints. In some situations, including accidents and roide sobriety checks, blood tests may be used.
Blood tests detect the actual presence of THC in the system; however, they can be sensitive to other metabolites as well.
Blood tests generally register positive for just a few hours after smoking, though heavy chronic smokers may be positive for up to seven days. While hair tests are highly sensitive to cocaine, their sensitivity to pot is not well established. Not all employers who use hair tests check for marijuana. Hair testing is racially biased against Africans, being much more sensitive to thick, dark hair than to light, fine hair.
Prospective employees have no legal right to challenge pre-employment drug screens. Avoid ing anything that gives your boss the right to arbitrarily test you; by stating your objections, you will strengthen your right to refuse a test. If you think you are being unjustly tested, you may have cause for legal action. San Francisco, Berkeley and some other jurisdictions forbid on-the-job drug testing except in safety-sensitive positions.
We are sorry having to mention these devious techniques, but feel it is necessary to defend innocent people against wrongful accusations of drug abuse. California NORML urges you to use this information responsibly and not as a way of hiding irresponsible marijuana use. Many drug abuse clinics offer urine testing for a fee. Home test kits are available from companies such as Liberty Research and Instant Diagnostics. Beware: drug urine levels can fluctuate up and down during the day.
Privacy: Urine tests intrude on intimate bodily privacy. Mass drug screening violates the privacy of the majority of responsible employees in order to spot a minority of alleged drug abusers, many of whom are in fact not drug abusers at all. However, the 4th Amendment does not generally apply to tests by private employers. Accuracy: No test is infallible. Surveys of drug testing labs have found remarkably high error rates from poor quality control.
The most common misconception about drug urine testing is that it detects drug-impaired workers, whereas it actually detects evidence of past drug use that need have no relation to on-the-job performance. Because drug tests are highly sensitive to marijuana, random testing can promote use of other, more dangerous drugs such as cocaine and opiates, which wash out in days, or LSD, which is rarely tested.
Urine testing is thus an inherently flawed technology: it rules out the most innocent off-the-job marijuana use, while permitting flagrant on-the-job alcoholism. Medically, the consensus of expert Will diluted urine pass a drug test is that drug tests are an inherently unreliable indicator of drug impairment Consensus Report, National Institute on Drug Abuse, Journal of the American Medical Association, Nov. Alternatives: The shortcomings of drug testing can be avoided by performance tests that measure actual concentration and reaction time instead of chemical residues.
Computer video game tests that detect impairment due to drugs, fatigue, stress, or illness are now available on the market Performance Factors, Denver, Col. Share this: Twitter Facebook. Like this: Like Loading Search for: Search.Will diluted urine pass a drug test
