What are the effects of cannabis drug tests?

The following substances are usually targeted by urine drug tests, according to a 2020 articleTrusted Source:

  • Alcoholic beverages
  • The drug amphetamine
  • Anti-anxiety drugs
  • The opiate epidemic
  • The drug coca
  • Cannabinoids

Cannabis is most ntatesting.com commonly diagnosed through a urine test. In this case, antibodies are used to latch on to THC and its metabolites in the urine drug test.

A positive test indicates that the antibodies have identified a drug.

The federal government sets drug concentration levels for urine drug screening, according to an article in American Family Physician (AAFP).

The test will return a negative result if it detects a drug below this concentration threshold. Follow-up testing may be required if a screening test results in a positive result.

Detecting drugs and their metabolites is more accurate with confirmatory tests such as gas chromatography and mass spectroscopy.

There is a possibility of false-positive results and false-negative results when analysing the results of a positive cannabis test.

Urine drug screens that come back positive unexpectedly should be discussed with a physician.

According to the AAFP, weed may be detected for up to 30 days after heavy use and for up to 3 days after a single use.

The body stores THC in fat compartments because THC is soluble in fat. A person’s kidneys eliminate the THC and its metabolites as they burn or recycle fat.

Additionally, researchers are investigating whether breath and saliva tests can be used outside of the laboratory to detect cannabis.

A breath test could theoretically be used by traffic police on the road to check for impaired driving. In spite of this, this technology is relatively new and we do not fully understand it yet.

What are the chances of you failing a drug test if you take CBD?

THC is also present in CBD-rich products, both of which are derived from hemp or cannabis.

Based on an analysis for 2019 Researchers in Germany found that 25% of CBD-containing food samples contained THC above the 2.5 milligram-per-day level associated with intoxication.

There may be a possibility that manufacturers do not eliminate the THC from their products, even if they claim to do so. In some cases, the product has not been tested by a third party or is incorrectly labelled, misrepresenting the amount of THC in the product.

It is also possible for people to receive a false-positive urine drug test result for cannabis or THC if they use other drugs, such as:

  • Cannabinoids
  • Ibuprofen, naproxen, and sulindac are nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Pantoprazole
  • The efavirenz drug

Passive, or second-hand, cannabis smoke exposes people to the possibility of testing positive on a saliva drug test, according to a study Trusted Source published in the Journal of Analytical Toxicology.

In an unventilated room, cannabis-free volunteers sat with five people who smoked one cannabis cigarette each.

Each of the cannabis-free volunteers had THC in their saliva, but these levels declined during the experiment. Outside of the study environment, researchers do not know whether second-hand cannabis smoke will result in a positive saliva test.

It was studied whether second-hand cannabis smoke could lead to a positive urine drug test in an older study.

Twenty-eight urine samples were collected 24 hours after cannabis-free participants were exposed to secondhand cannabis smoke. Despite only two positive samples, none of the samples exceeded federal thresholds.

In summary

Due to its non-intoxicating effects and non-status as an illegal controlled substance, CBD is not tested in drug tests. Even so, CBD users may fail a drug test. THC may be present in CBD products or the labelling may be misleading.

The results of urine drug screens may be impacted by other drugs and result in false positives. CBD products should be purchased from reliable sources that can confirm the product contains no THC if you want to avoid testing positive for THC on a drug test.
