According to an article published in Prosperous, a team from the University of Pittsburgh, including Dr. Ervin Sejdic, has created a breath testing device that can trace levels of tetrahydrocannabinol (THC) in a person’s breath. THC is the chemical responsible for most of marijuana’s psychological effects. These researchers developed it through the use of carbon nanotubes, which are miniscule tubes of carbon 100,000x tinier than a human hair.
According to this news article, the cannabinoid THC as well as other molecules in the breath bind to the nanotubes’ surface and alter their electrical properties. This causes the breathalyzer to signal the presence of tetrahydrocannabinol. The article went on to report that, “[t]his protype breathalyzer looks similar to that which is used for detecting alcohol. It has a plastic casing, a mouthpiece, and a digital display.”
Many law enforcement officers have long wanted a reliable method to quantitatively test for THC. The Drug Recognition Evaluations (DRE) are too often discredited by knowledgeable DUI defense lawyers. Therefore, there are a limited number of methods by which a DUI suspect may be properly investigated to determine the level of impairment by intoxicants or a combination thereof.
