Looks like it's triggered many, saliva tests, DNA stashed, it's our right to drive bombed etc.....
Interestingly it appears to detect some substances, you're then parked up for 12 hours, and when deeper tests come through they might add charges and demerits etc.
Tough for those on medicinal marijuana whose stuff suggests no driving for 6 hours i beleive, but it can linger in your system for days and detected.
They;ve had these tests in plenty of other places in the world, what's he likely they do something robust here, or fuck it all up and leave a few lawyers filthy rich helping people

Option 2 would be my guess. This wasn't just a few cops, over 100 have been identified.

The comments on fakebook from the most likely to fail the test are pure gold in proving why drug use is harmful to brain cells.
20 years ago random drug testing was a worry eg how do you protect yourself in false positive scenario? But after moving into modern era where it’s common industry practice now it’s stress free and you just don’t hear of false cases.
Saliva testing only really captures recent use, need piss test to catch out the hardened users who know the tricks. But it will at least take some off road.
As for medical M use, the proper prescribed commercial stuff doesn’t actually have THC in it although they can’t guarantee 100% removal. The problem is the prescription stuff is expensive. Many uneducated people will go to cheap tinny house stuff which is apparently lot more potent these days and your medical use does NOT cover that. Going to cost a lot of people licences and jobs who don’t listen to doctor’s instructions
What we really need is airport style sniffer dogs at high traffic areas to catch dealers
Green Party MPs will all have to take public transport options that they champion lol

the issue is the first test is for traces, not level, if there are traces you're off the road for 12 hours, if your on a busy road your car costs to remove, then if your test comes back from the lab under the level they deem harmful then what, you've been parked up for no reason.
what if you've just returned home from a country where it is legal to smoke so you've broken no laws?

Saliva test isn’t that sensitive, usage has to be fairly recent. Guys in workplace who are regular smokers that pass tests most of time.
Not sure where the closest “legal” country is but if you can’t manage your personal choices with a known flight window home then prob have trouble working out road rules too.
FB algorithms just bought up medicinal cannabis page in feed. Some munter has posted a picture of a 2017 Skoda with roof cycle racks claiming it’s one of the new speed camera cars. There’s all you need to know about drug use right there.

The new law doesn't prosecute you for drug use. It prosecutes you for having drugs in your system while driving.
So the overseas use case is actually only an offence if you then drive in NZ.

Yes, that pic was alleaging that the ANPR system is being used for government surveillance. It can track someone for 70 km, apparently.
Like, what has someone done to cause the government to want to track themn for 70 km?

Drugs in your system when driving or over a certain level in your system as that was what it seemed was going to happen after a positive test for traces is sent away????

Hmm, not applicable for me but got me curious. Found this.
Unfortunately, we know that saliva tests can detect drugs long after they’ve been used and long after someone is impaired by them. Unlike alcohol, where its presence in your blood or breath directly correlates to impairment, a medicine or drug can be detected in your saliva long after you stop being impaired.
More reading in a guide that should answer questions it seems.

The problem there is what one person may perceive as a”long time ago” and “impaired” prob differs from what the science and medical experts can prove.
Bloke A might just have a joint once every couple months catching up with mates while Bloke B might be a habitual user every few days or more. Bloke A can prob recognise his own impairment while Bloke B is permanently stoned but doesn’t think he is.
Had chance to listen to experts speak on the matter and it correalates with behaviour observed in those who you know are users. Decision making and the speed there of seems to suffer cumulative damage.
Just like when DUI came in people will just have to learn and adapt. It’s taken awhile but most people wouldn’t let a drunk mate get behind the wheel anymore….

In workplace a positive is called a non negative result and a puss test is needed for proper accuracy. So lawyers will have fun if word positive is bandied about when there exists clear evidence in various employment law cases no doubt about correct terminology and boundaries of saliva testing.
