Understanding Saliva Drug Tests

Employers and authorities prefer saliva drug tests over others because they can detect recent drug use. Urine drug tests can reveal if you have used drugs in a couple of days though not as accurately as saliva drug tests while follicle drug tests can’t detect recent use.

Saliva or oral swab drug test works by testing saliva to check if it contains a trace amount of toxins or drug metabolites.

Immunoassay techniques are initially used in saliva screening. It looks for the metabolites of a certain drug or its by-product. Afterward, for a positive test result, the sample saliva goes for a confirmatory test called GC-MS.

Gas chromatography-mass spectrometry assures the reliability of the first test averting the chances of a false positive.

How Does A Lab Tester Collect A Saliva Sample?

  • A cotton swab is positioned inside the mouth;
  • The swab then gets scoured along the cheeks and gums;
  • The swab stays in the mouth for a few minutes to absorb the saliva;
  • To avoid contamination, the sample is kept in a sealed container and sent to the lab;
  • On-spot saliva drug tests can produce test results in a couple of minutes;

What Type Of Drugs Get Detected In A Saliva Drug Test?

Before we explore how long does weed stay in your saliva, let’s find out the kinds of drugs it can detect. Oral fluid drug tests can trace a wide range of substances including:

  • Cocaine
  • Marijuana
  • Alcohol
  • Benzodiazepines
  • Opiates
  • Amphetamines
  • Methamphetamines

Situations Where Saliva Drug Tests Are Widely Administered:

  1. Roadside drug testing. To check if individuals are driving under the influence;
  2. Random employee drug tests. To ensure a safe work environment;
  3. Pre-employment drug test. To decide whether a candidate is eligible to join a specific workforce or not;
  4. Post-accident inspection. It helps uncover if the accident happened due to being under the influence;
  5. Legal issues; Parents fighting for custody or prisoners on probation often need to clear scheduled saliva drug tests;

The time it takes to get saliva drug test results may vary on two factors. First, if the sample is sent to a lab, it can take up to 24 hours. In an on-site drug test, it can take a few minutes. In case of a test with positive results, authorities can send the sample to another lab to confirm the accuracy of the saliva drug test.

What Does A Saliva Drug Test Result Mean?

Most U.S. labs test a sample for drug residues and compare its quantity with a substance’s cut-off level. A cut-off level depicts the minimum quantity of drug metabolites needed in a sample to get a positive result.

Every drug has a standard cut-off level and they can vary on the test type. You can get 3 types of test results in any kind of drug test:

Positive Negative Inconclusive
The result is positive when a test sample has more drug metabolites for a specific drug than the cut-off level. The result becomes negative if the amount of drug residues found in the sample doesn’t go beyond the cut-off level. It happens when you neither get a negative nor a positive result. Technical issues can cause this problem and you may get a call for a second test for a proper screening.

 

Factors Influencing How Long Does THC Stay In Saliva Glands

The mouth swab drug test weed timeline can vary depending on several factors. Below we have listed the most common factors for your understanding.

  • Frequency of use. Saliva glands can store THC metabolites for several days if you use cannabis daily whereas irregular users can get rid of the metabolites within 24 hours. It is the main factor during the mouth swab drug test for weed;
  • Consumed quantity. Like regular users, heavy weed users too retain drug residues in their saliva for many days which might not be the case if you use marijuana in a smaller portion;
  • The potency of cannabis consumed. If your cannabis product has a higher THC concentration the saliva gland will hold the metabolites longer;
  • Individual metabolism. People with better metabolic function flush THC faster than those with a low metabolic rate;
  • Oral hygiene habit. Although not a science-backed method, it is believed that good oral hygiene can reduce the amount of  THC residues in the mouth. Thus, brush your tongue and teeth thoroughly and use mouthwash;
  • Level of hydration. Dehydration can prolong the detection window. So, hydrate properly siping on fluids from time to time;

If people use THC with drugs such as antidepressants or alcohol, it can influence the detection window. Liver enzyme inhibitor drugs can affect the body’s metabolism rate. So, if someone is taking these drugs, it can cause THC to process slower and stretch the detection time longer.

How Long Does THC Stay In Saliva?

  • Smoking. Weed is often taken in this method and usually persists for up to 72 hours;
  • Edibles. It takes longer to flush out THC when it goes through the digestive system. Though saliva doesn’t hold edible THC for longer. It typically takes up to 48 hours;

How To Pass Saliva Drug Test For THC – Getting Rid of Weed Residue

People often prefer natural ways to get rid of THC metabolites. Below you will find the ways how to get rid of THC in saliva, but keep in mind – that the best method is time abstinence.

  • Maintaining saliva production. Newly secreted saliva has a lower concentration of THC so when you keep producing new saliva, it should get a negative test result. Chewing sugar-free gums triggers saliva secretion and hydration helps in this aspect;
  • Hydration. Drinking liquid from time to time helps cleanse the inside of the mouth lowering the level of THC.  It also creates new saliva which increases the chances of getting a negative result;
  • Time of abstinence. It is a surefire way to pass a saliva drug test. Just stop using weed for 24 to 72 hours if you are an irregular user. Abstain longer if you are a heavy or regular weed user;
  • Oral hygiene. Using good quality mouthwash and brushing your teeth thoroughly can lower THC concentration;
  • Gargling. Gargling with mouthwash or water can cleanse the mouth. It may not remove all the drug residues but can lower the metabolite count;

Home Remedies To Pass A Saliva Drug Test

  • Hydrogen Peroxide. A solution made of hydrogen peroxide and water is believed to help cleanse THC. It can mask the presence of THC at best but cannot be a permanent solution;
  • High-Fat Foods. People rationalize that since fat molecules tend to trap THC metabolites thus eating high-fat food will minimize THC absorption;
  • Sour Candies or Chewing Gum. This remedy works for a short time. Gums and sour candies can increase saliva production cleaning the mouth;

All these methods have their limitations. The most they can do is reduce the THC count in the mouth but can’t offer total cleansing. Abstinence from cannabis is the best way that work and get you the result you want.
