Colorado Is Funding A Marijuana Breathalyzer


marijuana dui duii oklahoma per seMarijuana opponents act like when marijuana becomes legal, our roads will instantly become so unsafe that everyone should fear for their lives. The fact is, traffic fatalities are at an all time low in Colorado after they legalized marijuana. But never mind that pesky fact, clearly there is a need to find ways to fix this problem that doesn’t exist (sarcasm). That’s why the State of Colorado recently granted $250,000 to a company that creates alcohol breathalyzers to see if they can develop a similar device for marijuana. Per The Cannabist:

The grant, which requires matching funds from the company, will allow Lifeloc Technologies to speed development of a tool that will be marketed to law enforcement, corrections, schools and workplaces.

“There is no equivalent of a marijuana breathalyzer today. Law enforcement does not have a fast, reliable and non-invasive THC impairment test available at roadside,” Lifeloc president Barry Knott said in a statement.

The fact of the matter is there will likely never be a device that can accurately measure current marijuana impairment. Yes, a device can detect if someone has marijuana in their system, but since marijuana stays in a person’s system for weeks and weeks at a time, there’s no way to determine if that individual had recently consumed marijuana, or had done so safely weeks before being pulled over on suspicion of driving under the influence. This grant is a waste of money, but I’m sure there are political motivations behind it, which is why I wouldn’t be surprised to see even more money thrown at the idea if/when it fails to succeed.

  1. thanks!

    If someone gets pulled over and subjected to the blood test and possibly busted for ‘drugged driving’, a quality defense would be a half empty bottle of Echinacea in the glove box

    Sounds like I am on my way to get a few bottles of Echinacea for my vehicles!

    You see, then they would have to prove it was cannabis instead of Echinacea in your system at the time of the blood test(which the blood was destroyed so they can not re-test the sample.)

    Possibly an expensive defense but do-able!

  2. Cannabis does not exit the body through the skin or breath like alcohol so the only way to measure how much is in the system is with a blood test, period.

    A weed breathalyzer is impossible. Cannabinoids are supposed to be in our system, that’s why we have CB receptors.

    A person does NOT have alcohol receptors(alcohol is accepted through CAA1 receptors), a person does NOT have opioid receptors, therefor a machine can measure stuff that is NOT supposed to be in our bodies but can not measure “unsafe” levels of substances that are SUPPOSED to be there

    With 10 minutes of research they could have found out it is impossible to test the breath for pot but the $250,000.00 grant was gladly accepted KNOWING there would be no results.

    Another wasted quarter million dollars by the haters trying to discredit
    and destroy a healing substance that they are clueless about but hate
    none the less.

    How can you hate something that you refuse to educate yourself about?

  3. I actually think it could work. I’m optimistic. The tech exists. And if Colorado figures it out — because they’re allowed to research freely — then it should only help the nation move forward with legalization in other states.

  4. The anti weed cops are put out because the easy busts have evaporated and they are looking for something easy to do for busts but I’m not sure that a breathalyzer for weed is even Possible.

  5. And add to the confusion is cannabinoids are also found in aa few OTHER plants that are legal.

    Cannabinoids from other plants[edit]

    Phytocannabinoids are known to occur in several plant species besides cannabis. These include Echinacea purpurea, Echinacea angustifolia, Echinacea pallida,Acmella oleracea, Helichrysum umbraculigerum, and Radula marginata.[36] The best-known cannabinoids that are not derived from Cannabis are the lipophilic alkamides (alkylamides) from Echinacea species.[36] At least 25 different alkylamides (dodeca-2E,4E,8Z,10E/Z-tetraenoic-acid-isobutylamides) have been identified, and some of them have shown affinities to the CB2-receptor.[37][38] In Echinacea species, cannabinoids are found throughout the plant structure, but are most concentrated in the roots and flowers.[39][40] Yangonin found in the Kava plant is a ligand on the CB1 receptor.[41] Tea (Camellia sinensis) catechins have an affinity for human cannabinoid receptors.[42] A widespread dietary cannabinoid, beta-caryophyllene, a component from the essential oil of cannabis and other medicinal plants, has also been identified as a selective agonist of peripheral CB2-receptors, in vivo.[43]

    Most of the phytocannabinoids are nearly insoluble in water but are soluble in lipids, alcohols, and other non-polar organic solvents.
