What I could find in regards to the levels; "A saliva drug test is deemed positive under the current Australian oral drug testing standards (AS 4760) for readings of or above 25 nanograms per milligram of THC (the active ingredient in cannabis) or 50 nanograms per milligram for methamphetamine, including MDMA."

i wish that was true...

(Edit)okay this seems legit from the link i posted below: they pretest at 25ng/mL and confirm at 10 ng/mL

here is what they use:

Furthermore, the latest saliva testing equipment, such as the Dräger DrugTest 5000 introduced in 2008, produces very reliable results. This device can detect very small quantities of active substances (THC: five nanograms per milliliter), and it pinpoints the time of drug consumption within a time window of up to eight hours, while only requiring a saliva sample volume of just 0.28 milliliters. “This makes it very easy to determine whether a person has taken one or more drugs recently and is still influenced by them,” says Dr. Stefan Steinmeyer, responsible for the subject matter of “Drug Testing”
at Dräger

this is turning into a real shit show...https://thewest.com.au/news/wa/polic...t-ng-ya-324121

In September 2014, a NSW Police report found the machines were failing to pick up on positive readings for THC despite a positive initial roadside swab test and an admission from the driver they had used cannabis in the past 24 hours.

“This is a substantial rise from the negative detection rate with the superseded COZART instrument," the report said.

“Other police jurisdictions report similar pattern of negative results in respect to THC on the Draeger instrument.”

Queensland Police reported a similar issue about the same time and reduced the detection rate in the machine from 25ng per one millilitres of saliva to 5ng.

NSW followed suit and also adjusted their detection rate.

Despite the tweaking, in June last year, NSW Police acknowledged the machines were not “picking up THC 100% of the time”.

hey mate. Do you know whether the THC detected in the saliva is from metabolites produced by the body, or from residue inside the mouth?

i was under the impression it was only residue that could be detected.... (so in other words, brush your teeth/tongue/mouth before driving...)

i've passed a roadside test coming home from the mardigrass festival at nimbin.... smoked a joint maybe an hour before driving, (after having a hotdog and a can of coke - which would have helped remove some residue) and was MOST DEFINATELY still high....

Hi Oz,
What about listing substances that can adulterate roadside drug testing as this is a war and we need ammo!
Recently I read hydrogen peroxide is good
Also have read vinegar too.
But I cannot confirm ,do you intend to test anything along these lines Oz?✌️

Two mates both recently passed NSW roadside after smoking within 10 or 20 min of a roadside test. One used Listerine strips and the other bit the side out of an orange, skin and all, as soon as he spotted them..

It sounds like they have these tests as roadblocks where you have to stop and they administer sobriety tests to everyone? Doesn't happen in my part of the US except once in a while near the ghetto on winter holidays. Usually the jails are so full they don't have room for extra visitors.
I don't worry much about that kind of thing because I'd have to commit a traffic infraction to get pulled over. Then I'd have to either act suspicious or have the car reek of ganja. I go with politely hostile with cops and they assume I'm sober.
My assumption, at least with the tests here, is that if I'd smoked within the last week I'd come out positive. Since it hangs around in your system for so long.
There's a lot of questions about the legality of the tests and what the threshold is. There's evidence that regular smokers drive as well as sober people, that it's not equal to driving drunk unless you're an inexperienced smoker. As the testing tech improves the legal defenses improve.
Very curious as to your results and what types of tests you're sampling. Right now I'm wondering what it takes to get a positive! Maybe how suspicious the officer is?

yes this is correct

yes i want to know as well: vinegar and hydrogen peroxide are the 2 most popular i have heard about but as rex mentioned coke and other high sugar/acid drinks may also work.

that is good to know especially since the NSW police test at 5ng/mL, hope i have enough tests to try something along these lines

that's exactly how they work..i have dodged that bullet twice now as they were full with cars as i was waved passed...

me too. testing at 25ng/mL seems pointless as it is 5x less sensitive than the police test at...and i couldn't get a positive with 2 loads of the mighty and smoking a cone. when my new tests arrive (12ng/mL) i will have 6 opportunities to test what times you need to wait to be clear was well as a couple of 'masking' agents.

[Old fark]

so how much is 5 Ng ?
Sounds like a very small amount ?
So how is Ng's of thc and impairment correlated?
Or is it just a case of negative or positive?✌️

Thanks very much for this thread it's been about 10 years since they introduced these in Victoria right around the time I got my license, and I resent potentially losing my job my life essentially everything every time I get behind the wheel when they don't even test for all types of Benzodiazapams, Opiates etc or the myriad other drugs that can hinder

I personally think that chronic cannabis users are safer on the road with a saturated endo cannabinoid system. I do not remember what it would be like to drive 6 hours after my last hoot but I honestly think it would be more dangerous.
