Drug tests have standard cut off concentration for detection for each drug and drug test, one reason is to avoid false positive results from second hand smoke, incidental ingestion, etc... for example .. standard THC (major marijuana metabolite) cut off for urine drug test is: most home test kits/ lab initial screen or immunoassay test - 50ng/ml (50 nano grams THC per 1 milliliter urine) and 15ng/ml at the Lab confirmation test usually GC/MS (gas chromatography - mass spectrometry ). Confirmation test is applied to samples that test positive during the initial test .. So concentration of thc above this cut off make test positive for thc.
There was a time where it would for thc, but anymore it won't. And even if it does on an instant test a follow up lab test will determine it isn't thc.
No, they typically use blood tests.
It all depends on your metabolism and usage. You can buy a self test kit and check it out. I think you can buy them at the pharmacy. Just a small note, if you are going to be tested, know that there are two kinds of urine tests, instant & lab and their cut-offs are not the same. For an instant test, the cut-off is 50ng, but for the lab it is 15ng. So Just because you pass a instant test, doesn't mean you would pass a lab test.
No K2 does not show up in a drug test. I believe that there is only one lab that can test for it and the test is pretty expensive. K2 uses synthetic THC to mimic real THC.
Meth Lab.
Yes. I an guessing you mean Hash or something similar by saying synthetic marijuana. A marijuana drug test is looking for the metabolite of THC. So if the drug has THC in it, which is what gets you high in marijuana, then it will show up in a drug test.
Most lab based urinalysis tests share the 50 ng ml cutoff tolerance that the home test kits have. For specific tolerances to each lab you will have to contact that specific laboratory and ask them what tolerance they can measure to.
Should Not as they are totally different molecules. If you test positive on anything request a retest as there is always a chance of lab error
Naproxen can show as THC on a screening test. If they send it to a lab with a confirmation machine, they can tell the difference there.
THC(tetrahydrocannabinol) at 50ng/ml"?Source: Erowid?Home drug test and Lab Initial Test (IMMUNOASSAY)- 50 ng/mlLab Confirming Test (GC / MS)- 15ng/mlBut military and some Lab -30ng/ml or less
Depends on lab n how they test ---- time is the best answer try to put test off 2-3 weeks n no toking!! Lol
