   Great question actually. The device works well for vaped and smoked cannabis. We generally see peak concentration 10 minutes after smoking, and a steady decay to 0 over the next few hours. We are in the midst of testing for edibles. What we

   There is actually a lot of peer reviewed articles supporting the fact that cannabis impairs driving. Here are a few articles you might be interested in. Ramaekers JG, Van Wel JH, Spronk DB, et al. Cannabis and tolerance: Acute drug impairme

   Thanks for your comment. Here are a few research papers you might find interesting: Ramaekers JG, Van Wel JH, Spronk DB, et al. Cannabis and tolerance: Acute drug impairment as a function of cannabis use history. Sci Rep. 2016;6(May):1-9. d

   Nice name for the device! To be honest, neither of the founders are electronics or software people, we are nanotech engineers. I don't actually know how useful the source code would be for determining if our device is working as intend

   Excellent point. This is something we have talked about internally a lot. Early on, we are really testing whichever people we can get but when we move into a full clinical trial we are definitely going to design the study to be as diverse a

   This comment comes from the fact that peak THC impairment occurs 1 hour post consumption (see the NHTSA Marijuana-Impaired Driving, A Report to Congress) and our average measurement at that time for THC in breath is around 0.00001 ppm. With

   It is not, but it does involve a gold substrate. We haven't found it necessary to include gold nanoparticles in order to achieve the required lower limit of detection.

   Yes we have. We have filed in Canada, the US, and PCT.

   We have tested vaping and smoking. We are in the process of testing tablets and edibles. Definitely a very important part of the equation.

    Great idea! We have actually been talking to a lot of TPAs (the organizations that do drug testing for industry). We have some interest, but unfortunately a lot of employers still have a stigma against cannabis. They are happy failing peopl

    Good question. Our current device only screens to see if you used cannabis in the last 2-4 hours (which aligns with the approximate window of impairment for cannabis). It does not actually assign a degree of impairment to a particular conce

    Confident that it will indicate, not necessarily confident that it will correlate (if that makes sense). The impairment window is approximately 2-3 hours post consumption. We can calibrate our sensor to have a threshold of detection that on

    Fair point. I think it is mostly a question of scale. Cannabis is the second most commonly used impairing substance after alcohol, and is becoming more prevalent every year. It would certainly be ideal to detect every impairing substance, b

    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 wo

    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 o

    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 institu

    Thanks for the comment. Do you know if these numbers of for possession arrests or impaired driving arrests? I have been trying to look for the impaired driving arrest numbers but haven't had any luck yet. One of the major roadblocks to

    I urge you to read the report. I think it relays a very balanced accounting of the facts. Its also a good place to find all the studies in one document, so I don't have to send you 100 links!

    Thanks for the comment! Impairment is the big question surrounding the enforcement of driving under the impairment of cannabis. It varies much more than alcohol based on BMI, age, and use history. Here are a few good resources for understan

    Thanks for the info. Definitely something we have not run into or considered yet. I guess we just naively assumed that all police precincts were as scrupulous as those we talked to :(. There is some stuff we can do, however. For instance, w

    Good question, especially regarding the DrugTest 5000 There are definitely some clear competitors in this space, but we feel that non of them have really been able to address the needs of the market. Ill start with the Draeger because it is

    Several reasons. To begin, police have very long sales cycles that are tied to their funding schedule. You need to make sure that you engage with them when their budget has been assigned but they haven't allocated to much of it. They a

    Great question. The two main competitors to our product is Hound Labs and Cannabix (the one you linked). Our main advantages over these two companies are cost and durability (which is kind of a proxy for portability). These advantages mostl

    You raise a good point. Interestingly, your comments run contrary to what a lot of law enforcement officers have said to us. In general, the police are hyper vigilant about buying only devices that are independently validated to be very acc

    Excellent point. The best solution to impaired driving would be a 100% accurate impairment test. The problem comes with designing and implementing such a test. Let's start with what they have today, the standard field sobriety test. It

    Thank you for your feedback. It is really valuable to get the perspective of a frequent cannabis user. Cannabis tolerance is definitely a huge factor in determining whether or not someone is impaired. As a daily user, I am sure you are fine

    It depends on the jurisdiction. In general, the police begin with a roadside test. This is either an standard field sobriety test (walking in a straight line, touching your nose, etc) or a screening breathalyzer. If the person fails, they a

    There is certainly a lot of confusion surrounding the effect of cannabis on driving. I would check out the report linked below. It provides a really good list of studies on cannabis and impairment along with summaries. https://ma
