What Is A Swab Test With Listerine Strips?

Drug testing is a common procedure in workplaces, schools, and other places where people gather. different drugs can be tested for, but the most common tests are for cocaine, marijuana, and heroin. 

The most common way to test for these drugs is by using a swab test. 

A swab test with Listerine is a common method for detecting certain types of drugs in urine. 

Listerine is a mouthwash that has been traditionally used to clear the throat and prevent oral bacteria from growing.   It can also be used as a drug test swab.

This is different from a urine test, which tests for the presence of THC (the main psychoactive compound in marijuana) in the urine. 

Swabs can be taken from different parts of the body, including the mouth and nose. Saliva samples can be collected quickly and easily, which makes them a popular choice for drug testing. 

4 Easy Steps on How To Pass A Swab Test With Listerine Strips

1. Abstain From Cannabis Or Any Form Of Drugs For A Minimum Of 48 Hours

If you are trying to avoid getting caught with drugs, and pass a swab test with Listerine, abstain from cannabis and other drugs for at least 48 hours before taking a drug test. 

This will help to reduce the amount of THC in your system and make it more difficult for the drug test lab to determine whether or not you have used drugs.

 To pass a drug test with Listerine strips, take a moist strip and place it on the inside of your cheek near your gum line.

 Wait 15 minutes for the strip to dry, then repeat this process two more times. 

However, If you cannot abstain for at least 48 hours, you can try to use a detox kit. These kits contain products such as Listerine strips which will mask the presence of THC in your system.

2. Have Food And Fluids In Order To Keep Your Mouth Moist

The one approach to passing a mouth swab test is by getting rid of the watery contents of your mouth. To do this, you must keep the saliva in your mouth moving. One good way to accomplish this is to consume and drink.

You’re usually not likely to need to change anything in your routine, so if you have 48 hours or more to the test, you definitely don’t need to change much.

 If you want, however, you should choose foods that stimulate your saliva glands and those with high water content; you’re also encouraged to watch out for thirst.

These consist of apples, carrots, cucumbers, celery, pasta, and cheese. Spices such as cayenne pepper, cardamom, cayenne, and ginger are integral to the inclusion of these foods as well. 

You should also stay away from foods that irritate your dry throat, such as soda, crackers, nuts, popcorn, and sweets with sugar.

3.  Keep Oral Hygiene ( Brush Your Teeth, Tongue, And Gum.)

Oral hygiene is important if you want to pass the swab test with Listerine as it helps to eliminate as much THC in your system as possible.

 Reliable resources recommend brushing 3-4 times a day (as usual). But you may need to brush for a few minutes more than the dentist recommends.

When you’re brushing your teeth, look up to the tooth, tongue, top, bottom, and sides of the mouth. Alternatively, you may also use Listerine, although you’ll need it the most on the day of the test. 

Using dental floss may also enhance your chances of passing the test since it occupies the places that your toothbrush doesn’t and, therefore, helps to get rid of more THC molecules.
