It is documented that white & black Americans consume roughly cannabis at roughly the rate, yet black Americans are 3.73x more likely to be arrested for it (figure from the ACLU). How is this device not going to contribute to that disparity?

Hey what's it matter when you're making $20/pop.

Is someone driving high dangerous?

Driving impaired in any way shape or form is dangerous. https://www.dailycamera.com/2016/06/09/affidavit-teen-driver...

Who's to say a 20 year old driving high is any more or less dangerous than an 80 year old geriatric? Drunk driving is definitively provable as dangerous, high driving is not.

You can also compare performance on other standard impairment measurements techniques, such as the standard field sobriety test, or driving simulators. There are a lot of studies looking at the effect of cannabis on these tests, although a lot of them suffer from really low doses. It is hard for researchers to get their hands on real world doses of cannabis for their studies because the drug is still schedule 1.

> It is hard for researchers to get their hands on real world doses of cannabis for their studies because the drug is still schedule 1. I hear this trope a lot, but considering the number of states in the US that it’s legalized in, can you clarify why?

For one, it makes it difficult for federally funded entities since the federal government views it as illegal. Also, lots of funding for state entities comes from federal sources. I have also heard of researchers having trouble with institutional review boards that still follow the federal guidelines.

In Texas, you receive a mandatory suspension for refusing just a breathalyzer, even if you are found to not be over the legal limit, or are never convicted of a DWI. Blood tests are then often obtained via warrant (and it's typical to have a judge "on call" to sign and fax those orders on demand)

That's utterly disgusting that the state can invade your body and take blood out with a warrant.

No it isn't. You are just hyper-sensitive.

There are times when it is necessary. The drunk driver who plowed into a family of 4 and killed them all? Fuck yeah I'm getting his blood - he needs to go to prison.

I'm sure this varies by jurisdiction, but I really wish my local police department (in Waterloo region) were willing to put even the slightest effort toward general road safety. As a four season bike/eskate commuter who wears a gopro, I am yelled at, swerved at, I witness drivers running stop signs, exiting driveways without looking where they're going, making RTOR without looking where they are going, driving at peo…

Where is the correlation between these events and driving high being "totally a problem"

The correlation is that it's not clear that lack of a roadside cannibis test is the most pressing issue preventing cops from making our roads safer. There are dozens of things that could be better enforced (especially with more commitment to automation), but even "progressive" police departments consistently choose not to pursue most of them.

Glad to see someone else from Waterloo in the comments! I'm not sure that what local police department serves your area, but the Waterloo Regional Police Service are actually really ahead of the curve when it comes to drug impaired driving. They have more drug recognition experts per capital than almost any other jurisdiction in Canada and if I am remembering correctly they are making it mandatory to train new recrui…

Yes, it's WRPS for me. To be honest, I've kind of given up hope. Until the current chief is replaced there's just not much point advocating for anything.

1) You mention THC. Do you test for CBD as well? 2) What if I walk around on the train or bus station, and I inhale some cannabis from someone who smokes? (This scenario is realistic for me.)

Good questions.

1. Our device does not detect CBD. It is specific to delta-9-THC. Our understanding is that CBD is not psychoactive and the police not interested in it.

2. As of yet, we have not seen any results from non-cannabis users on our device, some of whom were in the same room as our cannabis users when they used the drug. This will definitely be a focus of future tests for us, though. It would clearly be a huge problem if we returned positives from second hand smoke.

Would police be looking to use this as a pre-screen, and then take a blood test if your device reported impairment, or would they be directly using your test in court? Would it simply output the concentration, or would you provide added value via some sort of research/conversion chart that prosecutors can use in court to link the breath concentration to actual impairment, since most states don't have a statutory conc…

That depends on how the research and regulation surrounding cannabis shake down.

Right now, our device would just be used as a screen to see if someone had used the drug recently. The device's results would not be taken to court and would likely be followed up with a blood or urine tests (not ideal, but that is what the courts accept these days).

Our device has the capacity to output a concentration, but more research into THC content in breath and impairment needs to be done to see if that concentration means anything. Likely, if a link between breath concentration and impairment is established, there will be a statutory concentration set for cannabis.
