What Can Be Detected In A Saliva Test?

There are many things that can be detected in a saliva test which is why people often ask what can be detected in a saliva test. Saliva is a substance that comes from the mouth, and it has several functions. As a lubricant, saliva allows us to swallow food, drink liquids, and talk. Saliva also contains enzymes that help us digest food and fight off infections.

But what can be detected in a saliva test? Saliva can also be used in drug tests to determine if someone has recently consumed drugs or alcohol. For example, the most common test for marijuana is the saliva test because THC (the active ingredient in marijuana) stays in your system for up to 30 days after use. This means you could fail this type of test even if it had been months since you consumed marijuana.

What Is A Saliva Test?

A saliva test is a process that involves collecting saliva from the mouth and testing it for evidence of drug use. The tests are used to determine whether someone has ingested drugs, including marijuana, cocaine, and methamphetamine.

Typically, your doctor will ask you to spit into a cup or container. If this is done at home, you can use a plastic measuring cup or any other clean container that will hold enough saliva for the test. Your doctor will then send the sample to a lab for analysis. In some cases, they may be able to get results right away; otherwise, they may need to wait until they have access to more sophisticated equipment or processes.

Why Is A Saliva Test Done?

Saliva tests are most often used in connection with workplace drug testing programs because they’re easy and inexpensive compared with other types of drug testing methods like urine tests or hair follicle analysis (although these are also available). Saliva tests can be performed on-site so they don’t require sending samples off-site which means there’s no waiting time before results are available either!

What Can Be Detected In A Saliva Test?


If you’re asking what can be detected in a saliva test, you should know that alcohol can be detected in a saliva test for up to 12 hours after the last time that you have had a drink. This means that if you have been drinking, and then take a saliva test, there is a chance that you will test positive.

On average, one beer will remain in your system for one hour. One shot of liquor will remain in your system for two hours. A glass of wine will remain in your system for three hours. For most people, their bodies can process one drink per hour, but this varies greatly depending on factors like weight, gender, body type, etc.

You should also know that it takes about 30 minutes for alcohol to make its way into your saliva after you have taken a drink. This means that even if you did not plan ahead and brush your teeth or rinse out with mouthwash before taking the test, there is still a chance that you could pass the test if you wait 30 minutes before taking it.


Barbiturates can be detected in a saliva test. Barbiturates are drugs that were once used for anesthesia and sedation, but have now largely been replaced by benzodiazepines, which are a newer class of drugs. Benzodiazepines are also sometimes known as minor tranquilizers. In addition to this, barbiturates can cause breathing difficulties, so they have largely been replaced by other drugs that do not have these effects.


Amphetamines are stimulants that affect the central nervous system, increasing wakefulness and focus. Some of the most common street names for amphetamines are speed, crystal meth, uppers and black beauties.


A saliva test can detect traces of methamphetamine within 1 to 2 days after usage, although the exact duration depends on the amount of methamphetamine consumed.


A saliva test can detect cocaine use within 24 hours of taking it and will remain positive for up to three days after use. This means that someone who was using cocaine yesterday will show up as positive on their saliva test today and tomorrow as well. A saliva test is also useful because it can detect whether someone has recently used cocaine or has been abusing it over an extended period of time (such as years).

Saliva tests are not always accurate though; there are several factors that can affect results including: age (older people tend to have lower levels of dopamine which causes false positives), diet (eating certain foods before testing can also cause false positives), and medications (some prescription medications contain drugs that mimic those found in cocaine).


Opioids are a type of drug that can be received by prescription, but are also frequently obtained illegally. The drug attaches themselves to specific receptors in the brain and nervous system, causing a physical reaction that dulls the senses and creates a feeling of euphoria. They are widely used for pain relief, but they are considered addictive, with the potential to cause dependency and even overdose.


Benzodiazepines are a class of drugs that treat anxiety and insomnia. They are also commonly known as “benzos.” They are most often detected in a urine test, but can also be detected in a saliva test.

Is A Saliva Test Effective?

Saliva tests are effective in detecting the presence of drugs in individuals who have used them within the last few hours. They can identify recent drug use because the saliva most recently exposed to drugs contains the highest levels of trace substances. However, saliva tests have a relatively limited detection window; they are not useful in determining whether an individual has taken drugs in the past few days or weeks.

In addition to their usefulness in identifying recent drug use, saliva tests can be conducted quickly and easily, without any specialized medical equipment or training. The test results appear almost instantly after the sample is collected.

Which Is The Best Drug Test?

Urine tests are the most common type of drug test because they are quick, easy and cheap to do. They can also be done at home with an over-the-counter test kit that you can buy online or at your local pharmacy. You simply collect a sample of your urine in a cup and then place it into the testing device. It will then be analyzed for the presence of specified drugs. You may be asked to provide information such as your age, weight and gender so that they can adjust the sensitivity level accordingly.


Saliva testing is a relatively new concept, and it’s still in the process of being refined. As more physical and psychological factors are added to the models that predict drug abuse, saliva testing will become even more accurate. It will also be increasingly used in the workplace to detect employee substance abuse and ensure that employees who test positive on these tests are treated effectively.

There’s no guarantee that you won’t slip through the cracks if you’re addicted to drugs. But if your addiction is discovered early on by a professional at your workplace, there’s a better chance that you can get help for your addiction—and keep your job as well.
