Cannabix Technologies Inc. (CSE: BLO) (OTC: BLOZF) (the “Company or Cannabix”) developer of the Cannabix Marijuana Breathalyzer for law enforcement and the workplace, is pleased to report that recent characterization work with Cannabix’s FAIMS (field asymmetric waveform ion mobility spectrometry) THC detection device with human subjects has shown the ability to consistently discriminate unwanted ions from complex human breath background matrices allowing for THC (∆9-tetrahydrocannabinol) detection. In particular, recent testing with updated FAIMS cell geometries has shown the ability to consistently supress several compounds that are commonly found in breath like nicotine, garlic, onion, meats, ethanol, and volatile flavorants such as methyl salicylate and menthol (commonly found in gum) allowing for discrimination and mobility of THC in exhaled breath.
The Company is also pleased to report that engineers have developed a new atmospheric pressure chemical ionization source that provides significantly improved ion control in terms of intensity, stability, and focusing.
Early testing with high concentrations of a range of interferents collected from the breath of human subjects did not affect the sensitivity of the FAIMS device. These include complex matrices such as tomato juice and mouthwash. Testing with various common high salt and high sugar content electrolyte drinks was also conducted to determine if adduct ions would form that could interfere with the device, thus far none of these have done so.
Cannabix scientists have been focusing their efforts to complete characterization of FAIMS with various possible breath and environmental contaminants and are nearing completion of this phase of development. The Company then plans to initiate third-party testing by vetted professionals and piloting of the device. The Company has received interest in piloting from both U.S. and Canadian law enforcement groups as well as other organizations that drug test their employees.
About Cannabix Technologies Inc.
Cannabix Technologies Inc. is a leader in marijuana breathalyzer development for law enforcement and the workplace. Cannabix has established breath testing technologies in the pursuit of bringing durable, portable hand-held tools to market to enhance detection of marijuana impaired driving offences on roads at a time when marijuana is becoming legal in many global jurisdictions. Cannabix is working to develop drug-testing devices that will detect THC- the psychoactive component of marijuana that causes intoxication- using breath samples. In particular, Cannabix is focused on developing breath testing devices for detection of recent use of THC, in contrast to urine testing for THC metabolite that requires an invasive collection and reflects previous usage from days or even weeks earlier. The devices will also be useful for other practical applications such as testing employees in the workplace where impairment by THC can be hazardous.
