Different Types of Drug Tests

Without comparing there is no way of knowing which drug tests are better. Keeping that in mind, we are going to compare major drug test types with mouth swab test to see if it actually is the best.

Oral Drug Test vs Urine Drug Test

We all know that urine drug tests are very popular. But this seems to be fairly true in the past not at present. Now employers are looking for more convenient and less time-consuming types of tests. And mouth swab test fills in all the requirements. This is why employers are preferring saliva screening over urine drug tests.

We have already mentioned all the pros of oral swab drug tests. Urine drug tests can get awkward because sometimes they want you to take a supervised drug test. This means someone would be staring at you while you are peeing. But a mouth swab test doesn’t compromise your privacy. Coming to the detection window, if you are planning to cheat your way out of the drug test then a saliva drug test is the best option.

Just stop smoking pot for about 24 hours and nothing would come up in the test. Also, you can use a certain type of mouth wash which will get rid of the THC compounds. To pass a urine drug test you need to go through an intense detoxifying process. It takes a lot of time too and doesn’t even guarantee success.

Blood Test vs Oral Fluid Test

When it comes to accuracy, a blood test would come up at the top. It has a detection window of about 30 days which is far greater than mouth swab tests. But a blood test is an invasive method not to mention expensive. Another concerning matter is, blood test result carries a lot of private information. If someone wants, he can find a lot of things about you using the blood sample. But these are the last things you have to worry about with mouth swab drug tests.

Hair Drug Test vs Oral Fluid Test

Hair follicles drug test is another invasive and expensive type of drug test. Among other drug tests, follicles drug tests have the longest drug detection window of 90 days. In this type of test, the lab testers would cut hair from the roots to collect the sample. Also, you have to wait for a few days to get your test result. But mouth swab drug test provides fast results and costs less than a hair drug test.

Home Remedies to Pass a Saliva Drug Test

Refrain From Using Cannabis

The first and crucial step for expelling drug metabolites would be to stop consuming weed at once. You should do that from the minute you know you are going to take an oral drug test. For regular and heavy weed users this might quite a challenge. In that case, you might go without smoking pot for at least a day just before the day of your test.

Oral swab drug test THC detection time is short. Thus, even regular cannabis users can pass the test without any worries. The THC remains in your mouth for just 24 hours. This is why we recommend stopping consuming marijuana one day prior to the test.

Chewing Gums

Who would have thought that chewing gums can be this effective? Of course, you cannot hope to clear the test with your regular chewing gums. You would find several types of specialized chewing gums with neutralizing agents. Oral clear is a good example of these gums. These are widely used for cheating on a mouth swab test.

The gums typically have a type of fluid wrapped inside of it. When you bite into the gum the fluid residing in it comes out. It reaches every inch of the mouth. The mechanism behind this is that you chew the gum for a short time and let the juice cover your whole mouth. When you continue chewing the gum for several seconds, it results in detoxified saliva.

The effectiveness remains intact for about 30 minutes. And within this time, you need to take the saliva drug test.


Masking the existence of THC is enough to pass a mouth swab test. To do so you can try out sour candies. They increase the level of acid in your mouth. Candies tend to be high in sugar so it turns your saliva into a sugary and acidic oral fluid. When the testers take their sample from your mouth they cannot identify if the saliva sample has THC in it or not.

We wouldn’t say that this method is one of the best but if you are short on options this might work like wonder. But remember, the effectiveness doesn’t last long. You must go for the test as soon as possible otherwise lab testers would detect the presence of THC with no problem.

Eating Oily Foods

Eating junk food is another delicious way for passing a mouth swab test. This is one of the best alternatives for beating the saliva test. Foods like chicken fry, chips, burgers, or pizza contain too much oil. Although these foods are not good for your health, they surely can assist you in clearing oral drug tests.

When you eat these foods, the fat from them traps THC residues. Since drug metabolites are trapped in the fat cells, the doctors looking for the presence of THC cannot find it. That’s how the results come negative for a mouth swab test. Eat oily food one day prior to the test. If you don’t like junk food then make sure you are eating something very oily. It can be your regular meal but greasy.

Hydrogen Peroxide

Using hydrogen peroxide might be the most used home remedy to pass a mouth swab drug test. To use it take you to need to mix the peroxide and water. Take 3% of hydrogen peroxide with two parts of water. Now you have to mix it well and use the mixture to gargle. Gargling helps to expel THC residues from the mouth.

Hydrogen peroxide works as a detox mouthwash too. Thus, if you cannot find a detox mouthwash or are not sure if the product would work you can always rely on hydrogen peroxide. For that, make sure you have cleaned your mouth thoroughly. After that take the right proportion of water and hydrogen peroxide as mentioned and mix it.

When you are done, use the mix to swish several times and gargle. It is best if you carry on the routine of swishing and gargling for 5 minutes or more. Careful not to swallow the hydrogen peroxide mixed water. You can use it to wash your mouth as soon as you know about the saliva drug test. But remember to do the whole routine an hour prior to the test.

Although hydrogen peroxide used in the right amount is safe for the body. But when you use more than that it might create some discomfort. In the worst-case scenario, it can cause tissue damage. So, it is up to you if you would use it or not.


Vinegar is one of the widely used ingredients when it comes to home remedies. And guess what, vinegar comes in handy in beating mouth swab drug tests too. It flushes out THC from the fat cells by melting fat stored in your body. It also improves your metabolism rate.

According to some people, apple cider vinegar can help pass a mouth swab test if you drink it first thing in the morning. As per their statement, you need to continue drinking it on an empty stomach for about a week or more.

Another type of vinegar used for the same thing is called balsamic vinegar. We have seen many people share their success stories online stating how they passed saliva tests with balsamic vinegar. But these are all claims of random people without having any scientific evidence backing them up.


Another home remedy people use is Listerine. Many of us already use it to wash our mouths clean and keep out bacteria and germs. It refreshes your mouth and removes bad breath. Some pot smokers reported that regular use of this mouthwash helped them clear oral swab drug tests.

Of course, there is no concrete evidence that Listerine can actually help to beat a saliva drug test. The mouthwash isn’t specialized to do that.

Federal Laws Regarding Drug Testing

The Drug-free Workplace Act of 1988 is a federal law addressing drug abuse in the workplace. This law instructs that every employee involved in the transportation, aviation, or defense sector must undergo drug tests.

Scientists have done countless research on cannabis and according to some findings, it has some health benefits. Mainly after that, a few states have legalized the use of marijuana. That’s why the laws regarding the consumption of weed are frequently changing. Using cannabis is legalized or partially legalized in some states. Whereas some states do not consider people who use cannabis as criminals.

In a nutshell, the law varies from one state to another when it comes to marijuana. You have to keep yourself updated with your state’s laws if you don’t want to find yourself in trouble for indulging in weed.

The Bottom Line

Mouth swab tests are an effective alternative when you would like to eliminate any chance of tampering with the sample for a drug test. We all know that there are countless ways to cheat when it comes to hair follicles or urine drug tests. But it’s impossible to do the same with oral drug tests as the sample is taken by the testers.

Moreover, mouth swab tests are very convenient and less expensive. With this type of test, the doctors can provide quick results. Though it comes with many benefits the one thing which is a major drawback is the short detection window. So, how long does THC stay in your saliva drug test to be detected in drug tests?

Saliva drug test detection time THC is around 24 hours which is way smaller than urine or hair follicle drug tests. It can only detect the current consumption of marijuana. So, if that is what you want then mouth swab tests would be the best option to go for no question asked. It is an easy, and quick drug test method. It provides nearly accurate results.
