Mouth Swab Drug Test Detection Period Chart

How Long Are Drugs Detectable In Saliva Tests


There are several factors that influence how long substances stay in the saliva. An important factor is the frequency of drug use. The detection windows for different drugs are as follows:

  • Alcohol: 6 to 12 hours
  • Benzodiazepines: up to 5 days
  • Cocaine: up to 24 hours
  • Heroin: 2 to 24 hours
  • THC : 2 to 24 hours
  • Methamphetamine: 6 to 76 hours
  • MDMA: 1 to 24 hours
  • Opiates: 7 to 21 hours

These detection windows are shorter for some drugs than they are for others. However, some drugs remain in the saliva longer than they do in blood or urine.

For this reason, the type of drug in question could affect which of the oral drug tests are ordered. If your employer is trying to detect alcohol, theyll need to test sooner than they would for benzodiazepines.

How Does This Method Work

When you consume weed, THC gets into the blood through the lungs or the stomach walls.

After that, it is metabolized and excreted. But it never gets into the saliva.

The only THC in your mouth is THC that sticks to your mouth during smoking.

So all that you need to do is to wash it out of your mouth with water or any other liquid.

Are Saliva Tests Common

Swab tests are becoming more common among law enforcement officials and employers because they are cost-effective, easy to administer, and can be conducted anywhere, anytime. They can detect drug races sooner than a urine analysis considering it takes most substances a longer time to metabolize and appear in the urine. Still, they can be detected in the oral fluid in just a matter of a couple of hours.

Can You Pass An Oral Test With Home Remedies

Saliva Drug Test Kit Rapid Detect SDS 10 Panel

Some online guides recommend home remedies to pass a mouth swab test. But just because the remedies are popular, doesn’t mean that they actually work. None of the home remedies we’ll show you today have been designed to mask drug use, and none of them have any scientific studies or evidence to show that they work.

Someone who trusts one of these myths will be taking a massive risk in using a solution that has no real evidence to cleanse drug toxins from their system.

Here are the most popular myths on the internet at the moment.


Some people believe that dissolving Listerine strips in your mouth helps pass an oral drug test. They say that you should dissolve one piece on the inside of each cheek and one under your tongue to absorb any THC residue on the day of the test. You must also give your mouth a thorough rinse with Listerine mouthwash about 30 minutes before the test. Rinse with water to remove any lingering toxins and then rub two more strips in your cheeks on the way to the test.

The problem with this theory is that there’s no ingredient in Listerine known to detox drugs from saliva. It is made to kill mouth fungi and bacteria but will have no effect on drug metabolites from opiates, coke, THC or any other drug. You will definitely have the best smelling mouth in the test group, though.

Benefits Of Oral Fluid Testing Over Urine Testing


Oral Fluid Testing is the right solution if trying to screen for recent substance use, since saliva samples contain a higher percentage of the parent drug, compared to urine that measures only the by-product metabolites. Depending on the type of drug used and drug cutoff levels, drug detection times for saliva drug test kits are shorter compared to urine drug tests or hair follicle drug tests.

Oral drug test kits are very donor and administrator friendly. Oral fluid drug testing is non-invasive and allows for easy, supervised specimen collection. There is no need for the privacy of a bathroom, so it is virtually impossible to cheat a saliva drug test. Urine drug testing requires a bathroom for private specimen collection, and allows the individual the opportunity to tamper with the test.

Oral fluid testing is a great tool for employers to use at a workplace in order to facilitate a systematic drug check up ranging from pre-employment to post accident.
