Failing a drug test is not exclusive to people who usually use drugs only. In fact, there are various products which when consumed, will lead to a false positive in a drug test. Discussed here are twelve things that can make a person fail a drug test:
1. Vitamin B Supplements
Vitamin B12 is essential for the proper functioning and development of organs like the brain, blood cells, nerves and other vital organs of the human body. Some natural herbs contain vitamin B complex supplements that can lead to false positive results in a drug test.This is mainly because most commercial Vitamin B2 supplements are synthetic.
They are made by fermenting a particular plant, or they can be products of hemp seed oil. Presence of it in the vitamin B supplements will lead to a positive test for marijuana which will be false.
This is a non-steroidal anti-inflammatory drug (NSAID) and is a painkiller that most people prefer to use often to relieve pain. Using this painkiller could lead to positive test for barbiturates, Tetrahydrocannabinol or Phencyclidine. This is because Ibuprofen could contain substances like Sertraline and oxaprozin that have been identified as agents that have cross-reactivity with benzodiazepines to release components present in the three form of drugs aforementioned, and microcomponets like cannabinoid which are the principal psychoactive constituent of cannabis, highly lipophilic agents like diazepam, which can be detected in urine.
However, some evidence suggests that compounds with various differences in chemical structure, such as midazolam, chlordiazepoxide, and flunitrazepam, are not detected in many assays.
3. Poppy Seed Bagels
Poppy seeds are often thought to contain morphine but in actuality, they do not. But during harvesting, they can absorb or be coated by opium extract which is composed of approximately 12 percent morphine. Morphine can be detected in the urine up to 48 hours after ingestion of poppy seeds and their by-products. Eating bagels that contain poppy seeds as an ingredient raises the chance of the presence of morphine in urine which will lead to a failed drug test.
4. Granola Bars
Granola bars contain hemp seeds as an ingredient. Hemp seeds contain low levels of THC. Depending on the number of bars consumed, one could test positive for a drug test conducted for tetrahydrocannabinol, the active ingredient in marijuana.
5. Tonic Water
This carbonated soft drink contains quinine dissolved in it. Quinine was initially used for medication purposes to treat malaria and babesiosis. It is also used in cutting illegal drugs like heroin because of its bitter taste which complements the bitter taste of heroin.
Cases where quinine has been determined to be present in tonic water have results in urine tests that are positive for drugs like heroin and cocaine.
6. Cold Remedies
Colds prompt most people into consuming over the counter products (OTC) in an effort of remedying them. There are many cold remedies and here are a few that might lead to a failed drug test: Advil has Ibuprofen, which may lead to positive tests conducted for Marijuana. It might also test positive for Benadryl antihistamine that causes drowsiness and possibly a false positive for PCP.
Bayer Caplets cause false positives for Amphetamines.Claratin has the active ingredient Loratadine and Pseudoephedrine Sulfate which shows incorrect positive results for Morphine. Travist D which consists of multiple generic medications including Phenylpropanolamine which could lead to a positive test for Ecstasy.
7.Pizza and pastries
These delicacies contain yeast which makes dough rise by fermentation of the various ingredients. One of the ingredients is sugar whose byproduct of fermentation is alcohol. Though the alcohol content in these products can be close to minimal, if a breathalyzer test is conducted just a few minutes after eating pizza, one might test positive for alcohol which is a false positive result.
Antibiotics are usually prescribed medications. A number of them can trigger false positive urine drug screen (UDS) tests. Examples are amoxicillin and ampicillin. When a person ingests these antibiotics, they will be absorbed into the body system and their ingredients might lead to a false positive test for heroin and cocaine.
9. Baby soap
Ingredients of baby soap may have an impact on drug tests for marijuana which may lead to a false positive. These ingredients include polyquaternium-11 and cocamidopropyl betaine. Researches have not yet established why these chemicals interfere with drug tests and are still in the process of investigating. However, there are assumptions which try to explain this phenomena and they are Some compounds in the soap have a structure that may be similar to THC, or it could be that chemicals in the soap alter how the test works.
10. HIV medication
People living with HIV have efavirenz treatment as one form of medication. Efavirenz is an antiretroviral drug which can lead to false positive tests for benzodiazepines. This is due to the the structural similarity between efavirenz and benzodiazepines.
Benzodiazepines may have a similar chemical structure with marijuana hence a person who consume efavirenz could possibly test positive for marijuana drug tests.
11. Diet pills
Phentermine is a prescription drug for diet and is similar in chemical structure with amphetamine which is stimulant that is used for treatment purposes of attention deficit hyperactivity disorder. Amphetamine is a commonly abused street drug hence a person who takes phentermine for diet control could easily fail a drug test due to these similarities.
Antidepressants (TCAs) can lead to false positive tests for hallucinogenic drug LSD (lysergic acid diethylamide) which have psychological effects on their consumers. This is because of the 3-ring nucleus of TCAs present in the structure of this class of class of antidepressants. Many structurally related medications have proven to cross-react with TCAs in either serum or urine immunoassays. Antihistamine agents have been observed to to interfere with the serum immunoassay for TCAs. This reaction results in a breakdown of a byproduct contained in LSDs which explains false positive results for this specific kind of test.
