A 2009 study found that nearly 90% of tested energy drinks contained low concentrations of ethanol, which could cause false positives on portable breath tests, particularly within a minute of consumption. Beyond these beverages, many other common foods contain naturally occurring or added alcohol that can lead to surprising results.

Did you know that all fermented foods contain some level of alcohol, including kombucha? The trace alcohol content in kombucha raises a critical question for many: can kombucha show up as alcohol on a drug test?

Some older breathalyzer devices were known to be more susceptible to false positive readings from certain non-alcoholic compounds, including those found in mouthwash and some foods. This raises a critical question for many who consume sugar-free products: will sugar alcohol make you test positive for alcohol?

According to research, breathalyzers may detect trace amounts of alcohol from non-alcoholic (NA) beer shortly after consumption, with readings typically fading within 5 to 10 minutes. This is a critical consideration for anyone wondering how long does NA beer stay on your breath, especially those with strict alcohol monitoring requirements.

The milky white sap of wild lettuce, called lactucarium, is chemically distinct from controlled substances, meaning it will not cause a positive result on a drug test. Despite its folk name, "opium lettuce," this herbal remedy's compounds do not contain opiate alkaloids or other illicit substances detected by standard drug screenings.

According to scientific studies, many popular energy drinks contain trace amounts of ethanol, a byproduct of fermentation. While these levels are far too low to cause intoxication, they can temporarily affect breathalyzer results if tested too soon after consumption.

Certain B vitamin supplements, particularly those containing riboflavin (B2), have been linked to causing a false positive for amphetamines on initial drug screen immunoassays. Understanding this rare but documented phenomenon is crucial for anyone taking supplements before a screening.

According to verification tests conducted by news outlets, a breathalyzer can register a temporary, low reading immediately after drinking kombucha, but this effect typically disappears within 15 to 20 minutes. The trace alcohol in this fermented beverage can cause concern, but a legally significant reading is highly unlikely under normal circumstances.

The Seliwanoff test, a common method for distinguishing ketoses from aldoses, relies on a chemical reaction involving concentrated hydrochloric acid and resorcinol. Due to the use of these hazardous substances and a heating step, stringent precautions are necessary to protect laboratory personnel and guarantee accurate results.

According to the Food and Drug Administration (FDA), hulled hemp seed, protein powder, and hemp seed oil are generally recognized as safe (GRAS) for use in food. Still, many people worry, "Would eating hemp seeds show up on a drug test?" The answer is complex, but it's crucial to understand the risks, especially if you face regular workplace or athletic drug screenings.
