When representing licensed health professionals, our firm often encounters issues regarding positive drug tests that employers request. These clients include nurses, pharmacists, dental professionals, mental health counselors, therapists, etc. Job seekers should be aware that employers, particularly large companies and government organizations, may require drug tests as part of the hiring process. Medical and nursing students should be aware that prior to beginning clinical rotations in a hospital or medical facility, they will be given a drug screening test.

These issues are particularly relevant when a health professional has applied to a hospital, a medical organization, or a placement agency for work in a hospital and must submit to a pre-employment drug test. The client often contends that a positive result is a false positive and that some other substance must be responsible for it.

A positive result for any drug for which you do not have a valid prescription from a physician, including marijuana, can have severe and far-reaching consequences. It could result in being eliminated from consideration for a new job or termination from a current position. It can also result in a complaint against your professional license, which could lead to suspension or revocation. This could be devastating to your career and your future job prospects. Our firm is routinely called on to defend health professionals in such situations.
This blog series will discuss the potential causes for false positive results on THC drug tests and marijuana’s changing legal status on employer-ordered drug testing.

Remember to read Part 1 and Part 2 of this blog series! Part 1 deals with substances that may cause a false positive for amphetamines. Part 2 deals with substances that may cause a false positive for cocaine.

Marijuana (THC) False Positives.

The primary psychoactive chemical in cannabis is delta-9-tetrahydrocannabinol commonly referred to as just tetrahydrocannabinol or THC. Urine drug screens are designed to detect 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid (9-carboxy-THC). THC can be detected in urine for up to three (3) days for single usage but up to four to six (6) weeks after stopping long-term heavy use.

A false positive drug test occurs when the test detects a substance that is not there. This false detection is due to cross-reactivity with the urine drug tests.

Imposter substances for cannabinoids on urinalysis drug tests include cannabidiol (CBD) oil and other hemp products, HIV medications, ibuprofen, and other non-steroidal anti-inflammatory drugs, proton pump inhibitors, and baby wash products.

CBD is the second most prevalent active ingredient in marijuana. CBD is directly derived from hemp plants. Products made from hemp plants can have trace amounts of THC, even if THC is not on the label. Long-term regular use of CBD oil and other hemp products can build up enough THC in the body to test positive for marijuana and THC on urinalysis drug tests. Vitamin B supplements, like riboflavin, are made with hempseed oil and can also produce positive THC results. Despite the THC in the hemp plant, hemp products were legalized in 2018 under the Federal Farm Bill.

HIV and AIDS medications, like efavirenz and dronabinol, can produce positive urine drug tests for marijuana. Efavirenz is a potent antiretroviral medication used to treat HIV infections and dronabinol is used to treat loss of appetite and weight loss in people with HIV/AIDS. Dronabinol is also used to treat nausea and vomiting in chemotherapy patients. Dronabinol is classified as a cannabinoid because it is a synthetic THC that was legalized for medical use in 1985, which is why it can cause positive THC drug test results.

Pain medications, like ibuprofen and other non-steroidal anti-inflammatory drugs (NSAIDs), are over-the-counter medications that treat pain and fever. Ibuprofen medicines, like Motrin and Advil, and naproxen medications, like Aleve and Naprosyn, are NSAIDs that may produce positive THC results on urinalysis drug tests.

Proton pump inhibitors are used to treat heartburn symptoms and gastroesophageal reflux disease (GERD). Pantoporazole, a specific proton pump inhibitor medication, may cause positive drug test results for THC.

Commonly used infant and newborn soap products, like CVS Night-Time Baby Bath and Head-to-Toe Baby Wash, may cause THC-positive drug test results. Some health professionals speculate that positive THC drug test results are due to baby wash products containing ingredients with a chemical structure similar to THC.

Other discussions in future blogs.

In future blogs, I intend to discuss false positive drug results associated with poppy seeds, sleep aids, antidepressants, and other commonly used substances and medications.

Medications and Other Substances that Mimic Prohibited Drugs on Urinalysis Drug Tests: Cocaine and Imposter Substances (Part 2 of Series)

Author Headshot

By George F. Indest III, J.D., M.P.A., LL.M., Board Certified by The Florida Bar in Health Law, and Hartley Brooks, Law Clerk, The Health Law Firm

When representing nurses and other licensed health professionals, our firm often encounters issues regarding positive drug tests that employers request. These clients include nurses, pharmacists, dental professionals, mental health counselors, therapists, etc. Job seekers should be aware that employers, particularly large companies and government organizations, may require drug tests as part of the hiring process.

These issues are particularly relevant when a health professional has applied to a hospital, a medical organization, or a placement agency for work in a hospital and is required to submit to a pre-employment drug test. The client often contends that a positive result is a false positive and that some other substance must be responsible for it.

A positive result for any drug for which you do not have a valid prescription from a physician, including marijuana, can have severe and far-reaching consequences. It could result in being eliminated from consideration for a new job or termination from a current position. It can also result in a complaint against your professional license, which could lead to its suspension or revocation. This could be devastating to your career and your future job prospects. Our firm is routinely called on to defend health professionals in such situations.

Remember to read Part 1 and Part 3 of this blog series! Part 1 deals with substances that may cause a false positive for amphetamines. Part 3 deals with substances that may cause a false positive for Marijuana and THC.

Routine Drug Testing.

Most routine drug tests are “five-panel” urinalysis drug tests to detect marijuana, cocaine, opiates, amphetamines, and phencyclidine. Sometimes a “ten-panel” or “21-panel” test is used, depending on the employer. These drug tests are often immunoassay (IA) tests that screen for the common classes of drugs mentioned above. An IA drug test is typically used to evaluate the use of illegal substances and not prescribed medications or the abuse of prescribed medications. These drug tests will test for the drugs and their metabolites to assess usage.

A false positive is when a drug test detects a substance or metabolite that is not actually one that is from the prohibited drug. Instead, the test detects an imposter substance acting like the one it is looking to detect. Another urinalysis drug test used is a gas chromatography-mass spectrometry (GC/MS) test. This test is considered the “gold standard” of drug tests. But, due to its complexity and its cost, it is typically used only to confirm positive IA test results.

Cocaine False Positives.

Cocaine is known to have one major substance that will yield false positives in drug screens: coca leaf and coca leaf tea. Coca leaf is the source of cocaine, which is a Schedule II narcotic in the United States. Due to cocaine being an illegal substance, coca leaf and coca leaf tea are also illegal in the United States, both for brewing as a tea and for chewing.

Consumption of coca tea and the chewing of its leaves is common in South America, especially where coca leaf is grown in Peru, Bolivia, and Columbia. While coca leaf is illegal in the United States, it is still easily accessible for purchase over the Internet and in other countries. Urine analysis of subjects who ingested coca tea indicated that cocaine and two of its metabolites, benzoylecgonine (BE) and ecgonine methyl ester, were present in varying quantities.

Examples of False Positives from Coca-Leaf Tea.

We have had several clients who screened positive for cocaine on employer-ordered drug tests because of their earlier ingestion of coca leaf tea.

In one case, a nurse was visiting his grandmother from South America. The grandmother had a container of tea bags that looked like regular, commercial tea sold in the United States. He brewed a cup of tea and drank it, not knowing that it was coca leaf tea.

The next day, he had an employer-ordered drug test. His drug test was positive for cocaine. Backtracking to try to determine the source, we discovered the package that the coca leaf tea bags were in. They were clearly labeled “coca leaf” but were not labeled as containing cocaine, being illegal, or with any other warnings. The grandmother had brought these back with her on her last trip to South America.

In another case, someone had given a pharmacist a gift basket containing crackers, honey, teas and other different food products. A box of various different teas was included in the gift basket.

The pharmacist sampled the different teas at different times. However, when her employer ordered a drug test, it came back positive for cocaine. The pharmacist was suspended.

Backtracking to find the reason for the positive drug test, we located the gift basket’s label and contents and the tea box, showing that the coca leaf tea was included. The gift basket had been assembled in a foreign country and shipped to the pharmacist from outside the United States.

Amoxicillin and False Positives for Cocaine.

Amoxicillin is also rumored to be a potential source for a cocaine false positive for a urinalysis drug screening. However, a study in the Journal of Analytical Toxicology 2008 seemed to find otherwise. The results from the study found amoxicillin to be an unlikely imposter substance, although the scientific validity of the study might be questioned.

The study tested 33 urine samples from subjects who had been administered a course of amoxicillin. 31 urine samples tested negative; however, two tested positive for BE, a cocaine metabolite. The amount in the two samples that tested positive for the cocaine metabolite was less than 150 nanograms per milligram, the federal cut-off for cocaine. Therefore, the study concluded that amoxicillin is unlikely to cause a false positive urinalysis drug test for cocaine. Click here to read the full study.

I personally take issue with this conclusion. A big red flag here, however, is that this study does show that two out of the 33 samples were, in fact, positive for a cocaine metabolite, or at least its imposter. That’s six percent (6%) of the universe tested. With the millions of people who take amoxicillin every day, that equates to a pretty large number. If one million people each day are on amoxicillin, then this means 60,000 of them could test positive for cocaine on a urinalysis test.

The Centers for Disease Control (CDC) states that in 2019, 54.1 million prescriptions for amoxicillin were written in the U.S. If the same percentage were applied to this group, then 3,346,000 people would test positive for cocaine.

Furthermore, the drug screening tests used by many employers, especially those used by state-sponsored provider health programs or peer assistance programs such as the Florida Intervention Project for Nurses (IPN) and the Florida Professional Resources Network (PRN), often use a much lower cut-off level than the federal level.

One must also question whether the study used statistically significant samples and whether it would be considered scientifically valid. From the small numbers, it probably isn’t. However, it did produce some evidence that amoxicillin can cause a false positive for cocaine.
