The US Department of Transportation has granted Vox Biomedical a two-year contract to detect THC levels in drivers through their breath, to enhance road safety measures.
Fremont, CA: After the consumption of cannabis, the probability of the person being involved in a motor vehicle accident (MVA) increases almost twofold. Various studies have found that recent smoking and/or blood THC concentrations of 2–5 ng/mL are linked to significant driving impairment, especially among occasional smokers. Optical detection of THC in exhaled breath provides a quick, non-invasive, and simple method of identifying marijuana users without the risk of false positives, which is useful for law enforcement as well as industrial and commercial staff marijuana monitoring. The US Department of Transportation has issued Vox Biomedical a two-year contract titled "Detection of THC Use in Drivers via Breath." Vox Biomedical has also been listed under the Top 10 Law Enforcement Solution Companies by Govt CIO Outlook.
The ability to detect quantitatively diluted tetrahydrocannabinol (THC) aerosols from vape pen sources, as well as distinguish this intoxicating compound from the chemically similar, non-intoxicating compound cannabidiol (CBD), considered to have medicinal value, was demonstrated in earlier phases of this program. The Vox Biomedical equipment is designed to capture the THC aerosols included in marijuana users' exhaled breath and then quantitatively assess the captured aerosol content based on the infrared spectral absorption properties unique to THC aerosols. Exhaled breath samples can be labeled and safely stored for later use in forensic investigations. This technique and its uses have recently been the subject of a patent.
Following the first qualification, it is expected that the new exhaled breath analyzer will be commercially available within a year of the end of this development project.
