Cannabix Technologies Inc. (CSE: BLO) (OTC PINK: BLOZF) a pioneer in marijuana breathalyzer devices, has achieved a significant breakthrough by successfully detecting THC in breath samples after edible consumption.
This development could revolutionize drug testing and law enforcement practices, according to the company.
The company says its Mass Spectrometer Breath Sampler (MSBS) technology, in conjunction with the handheld Breath Collection Unit (BCU), has been consistently providing reliable results in the detection of THC in breath from smoking.
The MSBS technology has shown remarkable sensitivity in the low picogram range for THC in breath. This allows for the detection of THC from smoking and edibles up to four hours after consumption.
This level of sensitivity and the ability to detect recent use of marijuana makes the MSBS a powerful tool in law enforcement and workplace drug testing.
Cannabix’s has successfully detected THC in breath from edibles up to 165 minutes after consumption. The edibles consumed by various subjects contained a low of 10 milligrams and a high of up to 600 milligrams of infused THC.

Cannabix’s MSBS method for the detection of THC in breath presents striking differences compared to conventional, legacy methods. The MSBS is a novel method for efficient collection of analytes of low volatility from human breath utilizing liquid secondary adsorption. This method has demonstrated efficient capturing and releasing of THC.
Unlike legacy methods that require up to 15 minutes of solvent extraction, 150 min of preconcentration, and hours of chromatography, the Cannabix method can acquire results for a breath sample from start to finish within a few minutes without any sample preparation or pre-concentration steps.
Furthermore, the sample volume is smaller using Cannabix hardware which involves five breaths compared to over 10 breaths using legacy methods, which is easier and more convenient for subjects.

Cannabix has initiated discussions with industry-leading forensic laboratory organizations on how to best integrate its novel MSBS hardware into current forensic testing and analysis methods.
Scientists at Cannabix are also experimenting with a ‘quantification marker’ added to its breath sample cartridge for confirmation and potential quantification of THC in breath.
The company has recently delivered its BCU to the Friedel Clinic in Montana for testing with subjects.
Companies are focusing more on cannabis impairment testing devices to support law enforcement after legalization worldwide continues to spread.
Montana tech company Gaize, Inc. released a novel cannabis intoxication testing device last November that detects irregular eye movement in subjects who consumed cannabis. The VR headset assessment takes about six minutes to complete and has been tested on 350 participants in a recent clinical trial.
Other Canadian neurotechnology companies such as Zentrela Inc. developed the Cognalyzer, a device that measures the brain’s electrical activity to tell if a person is high.
