Founded 2014

Hound Labs, Inc. develops advanced breath testing technologies to address leading public health and safety issues. The Company’s flagship product is the HOUND® CANNABIS BREATHALYZER, an ultra-sensitive, analytical test that identifies active THC molecules in breath. Breath testing introduces the drug testing industry’s shortest cannabis detection window, giving employers a practical and objective solution to detect and deter recent use. By limiting cannabis detection to use occurring immediately before or during the workday, test results empower employers to maintain safe workplaces, improve hiring and retention efforts, and promote fairness in the workforce. For employer, law enforcement, and insurance use only. Not for any medical or therapeutic use.

How does Hound Labs measure their technology's effectiveness in the field?

The HOUND® CANNABIS BREATHALYZER uses sophisticated technology to quantify the amount of THC in breath. The company tests the performance of this technology via human studies under the guidance of protocols approved by the Institutional Review Board (IRB). The HOUND® CANNABIS BREATHALYZER is designed to meet standards set by lab instrumentation with tight tolerances and consistent, accurate results. Following standard chain of custody (CCF) procedures, the Collect + Send testing is performed at SAMHSA-certified lab(s) utilizing laboratory processing and matches the accuracy of any test using LC-MS analysis and instrumentation.
