Before a drug test, there are plenty of who fear that 2nd hand exposure to drugs will cause them to test positive: “If i eat a poppy seeds bagel, have the right to I test hopeful for opiates?” or “If i’m around second hand smoke, will I test confident for THC?” and also will they test positive? it is extremely unlikely.

All drug tests have what is called a cut-off level. This method that the test, whether urine or dental fluid, will only look for up to a particular amount the the medicine in her system. The simplest example of this is the alcohol breathalyzer test; if pulled end by the police, you are being tested v a cut off level that 0.05 BAC. Therefore if her breath test comes under 0.05BAC, you are not considered a danger to you yourself or various other drivers. An ideal levels that BAC is safety-sensitive work settings space lower.

The drug tests, much more specifically, space designed come have reduced off levels high sufficient to remove the possibility of the drug test being confident due to 2nd hand exposure. In other words, the reduced off level of any kind of test would have to be really low in order come catch second hand exposure, like eating poppy seeds, or being around weed smokers without smoking cigarettes anything yourself.


The Poppy-Seed-Defense

Research and studies have been performed in an answer to this issue, as human being have turn up confident results and also have used what is known as the “poppy seed defense,” whereby they case the hopeful was a result of eating poppy seeds, fairly than medicine consumption.

In a study released by Samano, et. Al in Journal of analysis Toxicology, participants who had actually consumed raw poppy seeds, and also participants who had actually consumed a role containing poppy seeds, were tested versus the common 2000ng/ml cutoff level. Participants to be tested for codeine and morphine levels via urine evaluation and oral liquid testing. Poppy seed lose around 80-90% of your opiate content throughout food processing, therefore it was discovered that consumption of life poppy seeds (25-40g) before either an OF or urine test are an ext likely to create a confident test result than all set poppy seeds, prefer the ones uncovered on bagels and in various other baking.

This study’s findings also suggest that the an ext time you provide yourself in between poppy-seed consumption and an oral liquid test, the less likely you room to test positive for opiates native any kind of poppy seed. Research and also studies suggest to the conclusion the if you were to eat a handful of life poppy seed the same day as an opiate medicine urine or oral liquid test, then yes, you may test positive. That is unlikely however possible. However, if you were to have actually a bagel or roll through poppy seed on or in it, girlfriend are also less most likely to test hopeful for codeine or morphine (the two opiates naturally found in poppy seeds). These are based on the laboratory results. The final an outcome is figured out by a medical Review Officer who will identify the impact, if any, the poppy-seed consumption.

The Canadian model for offering a Safe workplace (July 2018) recommends cut off levels for the naturally occurring opiates to it is in much higher than the semi-synthetic opiates such as hydrocodone or oxycodone: 2000ng/ml vs. 40ng/ml.

Second Hand Smoke

When introduce to the Canadian model, pee tests will an outcome in a confident for marijuana metabolites as soon as the urine display screen is equal to or higher than 50ng/ml, and oral fluid trial and error looks for THC in ~ 4ng/ml or greater on the early screen. While these levels may seem short to the layperson, they are sufficiently high to avoid a positive result due come second-hand smoke.
