How Does Saliva Drug Testing for THC Works

Consumption of cannabis, particularly THC, can be detected for up to six hours but this will also depend on the person and the type of test done. Undergoing a saliva test can be nerve-wracking, especially for first-timers. This test is different from the usual urine drug test. Others find it to be more accurate but there are also some people who find it easier to pass.

Here’s everything you need to know about this test.

What is a Saliva Drug Test?

The saliva test is an oral-based test that’s usually done by employers on site to randomly test their employees for cannabis use. This test is recognized by many to be more effective compared to other types of drug screening although it provides a similar result as that of blood testing. It’s commonly used for detecting cannabis use on the job or on the road during post-accident screening by police officers.

The saliva test for cannabis use specifically detects the presence of THC. This is because right after you smoke weed, the THC tends to linger inside your mouth before your body metabolizes it. This is what the test is trying to look for.

For How Long Does THC Stay in Your Saliva?

Most of the time, the saliva test is capable of detecting the presence of THC in your saliva within 24 hours since you last smoked. But this is not always 100% percent accurate because there are some saliva tests that could detect its presence even after 72 hours or more!

Therefore, if you’re a heavy smoker or cannabis, it may be best to avoid smoking for at least a week before the test in order to be safe. For occasional smokers, 3 days should be enough to guarantee a negative result. However, for random testing, you can only hope that the odds will be in your favor.

What About CBD?

Aside from THC, CBD is another substance that can be found in cannabis. However, unlike THC, this substance doesn’t come with any psychoactive effects, which is why it’s not usually tested in various states in the US. Furthermore, the government hasn’t imposed any standard measuring quantities for the presence of CBD in the body. So even if you have consumed hemp-based products that contain CBD, you can still come out negative in a saliva test.

However, for those who smoke products with high CBD strain, there might be a small amount of THC and this could get you into trouble if you’re undergoing a saliva test. Depending on the number of cannabis products that you smoke, you could either fail or pass a THC saliva test. There are simply no studies or trials done as of yet to determine for sure.

Even though the saliva test is still new, you can rest assured that it’s much easier to pass compared to the standard urine test that we’re already familiar with.
