what drugs does a mouth swab test for

Mouth swabs or saliva tests detect illicit substances from a person’s oral fluid. It is becoming the preferred drug testing method for many large businesses. But what drugs does a mouth swab test for? Read on and find out.

Reasons why some prefer the Oral Swab Test Kit

  • They are less invasive. There’s no need to prick a needle into another person’s skin or closely observe a donor while peeing.
  • Easier to administer. Just hand it to the donor, wait for a few minutes, read the results.
  • No need for private restrooms. You can administer this test anywhere.
  • They are tamper-proof. Drug testing oral swabs contain albumin that validates if the sample is saliva. So, the chances of cheating are nil.

What drugs does a mouth swab test for?

It depends on the number of panels of the mouth swab drug test. 

For example, the 10-Panel Oral Drug Test screens for ten drugs of abuse. These are:


Amphetamine is a drug that stimulates the central nervous system. It enhances a user’s alertness, concentration, and self-confidence. For this reason, doctors typically prescribe AMPS to treat narcolepsy and ADHD. Additionally, it decreases appetite while giving a sense of increased energy. Thus, doctors recommend it to treat obesity. 

However helpful this drug is, some people who always need extra strength and stamina abuse it. For example, some athletes use it to enhance their performance during competitions.

Amphetamines can be detected in saliva for up to five days at a cut-off level of 1000 ng/mL.


on the other hand, BARs are depressants that make users feel calm and drowsy. Doctors prescribe it to treat severe headaches and for controlling seizures. It can be detected in saliva for up to three days.


Benzodiazepines are central nervous system depressants and are among the most commonly prescribed in the U.S. today. There are over 15 types of benzodiazepine medications on the market. 

Benzos like Alprazolam, Clonazepam, and Diazepam can be detected in saliva from 2.5 to 9 days.


BUPs like Suboxone were created to treat opioid addiction. As stated in an NCBI article, “Buprenorphine pharmacotherapy has proven to be a treatment approach that supports recovery from addiction while reducing or curtailing the use of opioids.”

However, BUP’s advantage turns out to be a disadvantage too. Because it provides the user with the same effects as opioids, BUP tends to be abused, especially by people who do not have an opioid use disorder.

BUPs stay in the saliva for up to three days.


One of the drugs that’s famous for binges is cocaine. It’s because this highly addictive stimulant provides the user with a rush followed by a high. But due to its short half-life, users tend to retake coke to experience that rush and high again. Unfortunately, binges lead to terrible crashes.

A saliva drug test can detect cocaine for up to two days after consumption.


The most debated drug, marijuana, contains the brain-altering substance Tetrahydrocannabinol (THC). 

When someone smokes or takes marijuana orally, THC attaches to the cannabinoid receptors in the brain. These receptors are in the areas of the brain associated with learning, memory, pleasure, and time orientation.

The euphoric effects that marijuana is famous for come as a consequence.

In occasional users, weed can be detected in saliva for up to three days. However, in heavy, chronic users, an oral fluid drug test can detect marijuana for up to 30 days.


Methamphetamine is a powerful stimulant initially developed in the 20th century. Although it has therapeutic applications, it is mostly being misused by people who have developed an addiction to it.

Additionally, methamphetamine produces that popular high, which is sought by its users. As a result, it heightens the senses and induces euphoria when taken in higher doses.

Mouth swabs can detect meth in saliva for up to four days after use.


Doctors prescribe this opioid analgesic for severe pain relief. However, it has a high potential for addiction, and users can rapidly develop a tolerance for it.

An oral fluids drug test can detect morphine for up to four days after last use.


Oxycodone comes from an alkaloid of opium known as thebaine. However, its effect is twice that of morphine and would lead to addiction stronger than some other opiates such as codeine.

Consequently, misuse and abuse of oxycodone can lead to overdose and death.  

Oxy can stay in saliva for up to four days after use.


Some people use Phencyclidine, more popularly known as PCP or angel dust for its mind-bending effects.

Typically, users snort PCP or inject it into a vein. Once it enters the system, PCP concentrates in the brain and fatty tissues. Sadly, young adults and high school students are the ones abusing PCP the most. Some of them start as early as 12 years old.

A mouth swab drug test can detect PCP for up to three days after consumption.
