As many are aware accuracy of Saliva Drug Testing and the detection of THC is frequently questioned. There is substantial research in the last 15 years that indicates that Saliva Drug Testing for THC is quite unstable, even with monumental advances in technology in recent years it still remains so. I don't want to create a "how to buy good marijuana article" however some practical facts need to be covered as well as the technical information.   Below is a typical product insert for a saliva test device showing the types of THC molecules tested. This tests detects both the Parent THC and the metabolite THC-COOH   Δ-9-tetrahydrocannabinol (THC) (Parent) 50 ng/mL (-)-11-nor-Δ 9 -THC-9-COOH 12 ng/mL 11-Hydroxy-Δ 9 -THC 300 ng/mL 11-nor-Δ 8 -THC-9-COOH 12 ng/mL The emphasis is on detection of the Parent Drug at 50ng as that is deposited in the mouth via when marijuana is smoked.

Saliva Drug Testing Saliva Tests for drugs is the least invasive and fastest way to test for current impairment from drugs in the workplace. As with any rapid test method including urine drug testing, a Non Negative result needs to be confirmed by a laboratory i n order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) or Liquid chromatography/mass spectrometry (LC/MS) are the preferred confirmatory methods. Here are some Questions and Answers regarding issues some have with Saliva Testing: Q: I had a candidate submit a negative test when the person appears to be under the influence of drugs or something else. A: There are a number of possible explanations:       1. I assume the candidate was tested for Alcohol       2. If the Saliva Test did not have a Benzodiazepine test strip this could be the cause.       3. There are very few substances or adulterants that can provide a false negative test            with saliva. MediNat will s

Workers dodge positive drugs tests 26 March, 2013 Vicky Validakis Mining Australia The Article (see below for comments) Industry drug testers have raised concerns that workers are managing their illegal drug intake in a bid to escape getting caught out in tests. Kerryanne Tawhai, director of Down to Earth results, a company that tests illegal substances in resource industry workers, expressed concern that workers were managing their drug intake to avoid testing positive to drugs, including amphetamines. The comments come after Queensland Police in Gladstone raided a suspected methamphetamine laboratory in West Gladstone on Friday. "(It) goes with the territory," she said. "You've got large a congregation of people and there's nothing really to do in this town." She said most people know that these type of drugs left the body in a short-time, enabling users to adjust their usage before they go back to work on mine sites.
