New THC Breathalyzer Coming Soon?


I’ve done several posts on whether we could be seeing a breathalyzer for marijuana soon. The latest reports on a marijuana breathalyzer are coming from one of the states which have recently legalized recreational marijuana.

Researchers from Washington State University are also working on developing a breathalyzer for THC, the psychoactive component of marijuana.

WSU chemistry professor, Herbert Hill, said that current techniques used by airport security and customs agents to detect drugs can similarly be used to detect the THC in a person’s breath.

Like other prospective THC breathalyzers in development, the THC breathalyzer in development by WSU will not be able to detect how many nanograms of THC per milliliter of blood are present. But, according to Hill, the THC breathalyzer will be able to let officers know if some THC is present.

“We believe, at least initially, that it would lower the false positives that an officer would have,” Hill said. “They would have a higher level of confidence in making an arrest.”

If you read my posts, you’ll know that the legal limit for THC is states that have legalized marijuana is five nanograms of THC per milliliter of blood.

I’m sorry for sounding like a broken record, but THC located in the blood is not an accurate measurement of intoxication!

THC can stay in the blood for weeks, if not longer, after smoking marijuana. This means that a person can be arrested for a marijuana DUI, even though they are stone-cold sober, merely because they smoked marijuana weeks ago.

Until a breathalyzer can detect intoxication from marijuana rather than merely the presence of THC, we shouldn’t be using it.

    In states and provinces with zero tolerance this would be an amazing tool. For the workplace it would also work well. The fact you seem to be a DUI lawyer and are against this product makes me wonder if you feel it will be taking away some of your business. I think you are misinformed on how this device works and the legalities involved. Do your research.

    BTW Cannabix technologies is light years ahead of WSU in product development and patents.

    Bob bob, apparently you are a complete collectivist and control freak. Zero tolerance is absurd on its face and to see someone actually endorsing it is breathtaking to say the least. Are you a closet communist or a sociopath? What makes you thing you have the right to force your opinions on others? News Flash – the US was founded on personal freedom and what people do on their own time is NONE OF YOUR BUSINESS!!!!

    As for your snide comments to Lawrence, from all of his work I have read, he is more concerned about the loss of freedoms, the Constitutional violations and our descent into a police state than he is about having more clients to bill.

    Either educate yourself or, if that is not possible, move to a country that more suits your views, like North Korea.
