Drug Testing Information

The following is a wealth of information regarding drug testing compiled from various sources.

From The Tester's Point of View

Alcohol is not one of the drugs commonly included in an instant (dip or split cup) type test. The most common drugs tested for in a five-panel instant urine test are a combination of any five of the following:

  1. Methamphetamine
  2. Amphetamine
  3. Cocaine
  4. Phencyclidine (PCP)
  5. Marijuana
  6. Opium
  7. Ecstasy
  8. Benzpdiazepines
  9. Tricyclic Antidepressants
  10. Oxycodone

The employer chooses what combination of drugs he or she wants to have tested. Instant devices come anywhere from one-panel (for only one drug) or up to ten-panel. The cost is not much different, maybe $5-10 bucks higher for the ten-panel. I know the ways that will work to fool a drug tester and I know the ways you can get caught by a drug tester or a lab. I am a drug tester. You are right about the insurance industry dictating the need for testing. However, John Q. Public is as much to blame as the insurance industry. With everyone suing everyone else over the slightest breeze of assumed liability and no one taking responsibility for their own mistakes, you can't really blame the employers for going over the top trying to eliminate any risk factor they can. Employers are only protecting their income source. Why should they risk their families' support system just so you can get high?

Back to the alcohol. That is generally given either as a saliva or breath test using a breathalyzer machine. There is no way to fake a breathalyzer. We "screen" you, by doing a breathalyzer test, then if you show 0.02 or above, we wait 15 minutes, not letting you drink or eat anything (or use nicotine products) and test you again. The second test is the confirmation test and is used to ultimately determine the blood alcohol content (BAC).

If anyone wants to find out what drug testing is all about, the how's and why's, simply go to a testing site and ask. Why do all you people depend on hearsay and rumor? For anywhere from $15 to $50 you can be given a instant test for any combination of drugs in a testing environment. Most instant devices detect lower levels than a regulated test in a lab. If you want to know what a regulated test is, just go to a testing site and ask!

By the way, I am not against marijuana use. I have friends in California using medicinal and non-medicinal marijuana. I don't see them as any different as myself, except that I don't use. I just wouldn't trust them not to "Wake & Bake," then drive my kids school bus. It has been my experience that most, not all, but most users can't seem to stop at once or twice a week at home. Eventually the marijuana gets into the lunchbox for a quick noon-time relaxer. That is what the employers are afraid of as well.

The Temperature On Your Sample If You're Subbing

Take the cup and urinate in it. Let it come to temperature (about 20 to 30 seconds), dump it, put in your substitution, zip it up, and hand it to the collector.

There is not enough of your urine left to contaminate the sample to a positive. The temperature will drop one or two degrees, but not enough to cause a flag.

If you know you are going to be observed, dilute.

For references, I have done this method twenty-seven times in ten years and have never had a problem with the results. Those heat packs are awkward and can make it to hot or not work at all.

Food & Medicine That Interact With Drug Tests

Be aware that certain foods and over-the-counter medications can cause you to test "positive" for various kinds of drugs.

Poppy seeds, for example, can show up on a drug test as morphine. Cold remedies that contain codeine can also cause a positive result for morphine.

Valium reportedly can produce erroneous indications of phencyclidine (PCP), and other cold remedies can apparently produce false reports of methamphetamine usage.

Dextromethorphan can produce a falsely positive qualitative urine opiate screening.

The widespread availability of hemp-containing products, including everything from hemp-seed oil nutritional supplements to hemp-seed candy, cookies, cheese, bread, cooking oil, and general seasoning, means that ingesting ANY of these products could potentially cause a false positive result on a test for marijuana.

Ibuprofen, contained in Advil, Nuprin, and Mortin, can make a positive result for marijauna. The EMIT test (an immunoassay test) has therefore been changed to use a different enzyme to eliminate false positives due to Ibuprofen. Ibuprofen in very high doses will still interfere with both the EMIT and the gas chromatograph-mass spectrometer (GC-MS) test.

Ibuprofen is a common pain reliever that (even in low dosages) used to cause a false THC positive on the EMIT test. The EMIT has been changed to use a different enzyme to eliminate false positives due to Ibuprofen. Ibuprofen in very high doses will still interfere with both the EMIT and the GC-MS. There is some conflicting data here because some sources say that the GC-MS tests can distinguish between Ibuprofen and THC (as well as other over-the-counter drugs).

Common over the counter cold, asthma, and allergy remedies and diet pills such as Diatec, Dexatrim, Cotylenol, Triaminic, Primatene, Bronkotabs, and Nyquil can show up as positive for amphetamines.

Vicks Formula-44, Demerol, Mydol, Primatene-M and common prescription antidepressants such as Elavil and Tofanil can show up as positive for opiates such as opium and heroin.

Ephedra, also known as Ephedra Alkaloids or "MaHuang Extract" has a chemical structure which is closely related to amphetamine, and can reportedly give a false positive for amphetamines. Often sold as an "energy pill" it is an effective decongestant in low doses.

Valerian root is reported to cause false positives for benzodiazepines. Other herbal supplements such as Kava Kava and St Johns Wort may also affect body chemistry such that false positives are produced.

Zoloft (Wellbutrin) is reported to cause false positives in urine screens, although for what specific substance isn't clear.

Primatene can also show up as positive for barbiturates, and Benadryl can show up positive for Methadone.

Some additional over the counter medicines that may cause various kinds of drug test interactions include Alka-Seltzer plus, Allerest, Bronkaid, Contac, Donnagel, Sinuntab, and Sudafed.
