Following my prior investigation
What could lead to exaggerated positive lc/ms ms test fortetrahydrocannabinol and liquid chromatograph analysis for THC:

How effective is decarboxylation of THCA (tetrahydrocannabinolic acid) by citric acid? Only citric acid in solution is used without addition of heat.

For context: please refer to my other question. It relates to a mission to find out why a person (me) could test positive for a THC saliva test without consuming any cannabis products. The focus currently is on the use of citric acid in the saliva collection device.

As you could see in my other post, the only contamination I had prior to being subjected to the saliva test was smelling at some dried cannabis buds. Since fresh cannabis contains mainly the non psycho active THCA, I am trying to find out what led to my positive test for THC. My focus is currently on decarboxylation of THCA by citric acid which is an ingredient used in the saliva collection device.

    $\begingroup$ yes of course I am the author of the other post. Why would this question be suspicious? I am trying to find out why i tested positive for a THC drug test while not consuming any cannabis. This could be relevant for many other people in the future as to understand what factors could lead to a false positive result. You can read the whole story in my other question. So now my focus is on the use of citric acid in the collection media, hence the question. $\endgroup$

  • $\begingroup$ Yes Poutnik I understand what you are saying. Indeed the question was a bit short and without context could be suspicious. I have added some context now. The main context however is that this question is related to my first question as to find out why I tested positive for a THC saliva test only by smelling dried cannabis buds. I think I am on to something regarding the collection device used. But I am not knowledgeable enough to confirm the chemistry behind it. $\endgroup$
