Salivary tests to monitor the amount of THC: how they work and how to avoid them

Here is everything you need to know about salivary tests for THC  and some tips for having a negative result in case of control.

In Italy and in many other countries of the world, cannabis is still considered by many to be a drug in all respects . Despite the great successes of the pro-legalization movements and the burgeoning cannabis light business, many employers continue to test their employees for THC and other substances. One of the most popular is the drug salivary test, let's see together the characteristics of this (currently unreliable) exam.

Drug checks that look for tetrahydrocannabidiol  (the psychoactive molecule of cannabis)  have recently taken a major step , although urine and blood tests are still widespread, there are more and more instant tests taking place on saliva. These principals are of relatively recent creation and have a number of notable flaws, especially with regard to false negatives. In fact, they are particularly easy to "fool" by using small precautions before supporting them. Furthermore, given the large margin of error they show, even if they are positive you can ask for the possibility of carrying out a new confirmation test, given the high unreliability and the lack of rules in this regard.

Difference between saliva and urine tests

Today the saliva tests for the search for drugs by employers or in any case by private individuals are undoubtedly the most used of all because they are quick to carry out, cheap and not at all invasive . Although they are celebrated as very accurate and reliable, the truth is that it is possible with a little preparation to influence the result.

First, let's try to understand the difference between these and the classic urine tests: the former detect the actual presence of THC in saliva while the latter look for a THC metabolite, that is a substance produced by the passage of THC in the body that remains in circulation for long time. This makes us understand that a saliva test carried out immediately after smoking will probably be positive but, since THC remains for a limited time in the mouth of smokers, there is a very good chance that it will not be found if one does not take it regularly but only. occasionally.

THC in saliva: how long it stays and in what quantities

It is not a very reliable calculation but if THC is taken occasionally the levels of this molecule in the saliva can already appear close to zero after only 3 days . For the most frequent users, however, it is difficult to have a negative result before 10 days of abstinence and many tests have shown to detect traces of Tetrahydrocannabidiol even after a month.

Does choosing cannabis light help to have a negative saliva test result?

Obviously, in addition to how much you have smoked and how long the result will also affect the quality of the marijuana you choose, the richer it will be in THC and the more it will leave traces. For this reason, choosing light cannabis will give you a better chance of passing a saliva test in less time since your last joint.

Methods for having a negative test (in addition to abstinence)

If you are looking for a last-minute system to decrease your chances of being positive in a test, we recommend that you take the following precautions:

Maintain impeccable oral hygiene , especially before arriving at work if you suspect or know of a checkup;

Brush your teeth repeatedly at least 3 or 4 times a day , always use a mouthwash, possibly an alcohol-based one that removes even more THC residues but above all will help dilute the cannabinoids in the salivary fluid;

Drink plenty of water and eat calorie and fatty foods  (lipids help absorb and then dispose of THC).

Can you test positive if you only take CBD?

Fortunately no! If you are a regular consumer of CBD and do not want to give it up but you are at risk of control, we recommend that you choose to take it with preparations and concentrates that do not have traces of THC . In this way you will not be able to test positive in any salivary drug test, as cannabidiol in Europe is not considered a doping substance and therefore is not investigated in the tests. Obviously, pay attention to products that contain both cannabinoids, because if you are unlucky, even the slightest trace of THC (such as that present in legal cannabis) can be detected by an unexpected test .
