Product Testing

Since 2014 we have been extensively testing the science, technology,
and engineering in the Hound® marijuana breathalyzer.


The Hound science and technology have been analyzed and evaluated in the lab, at the roadside by law enforcement, and with human subjects in controlled environments.
