About
Hound Labs develops ultra-sensitive breathalyzer technology for the accurate detection of very recent cannabis use. The HOUND Cannabis Breathalyzer provides fair, non-invasive THC breath testing — detecting use within hours, not days — enabling employers to ensure workplace safety while respecting employees who use marijuana legally outside of work. The technology also extends to COVID-19 and other breath-based diagnostics.
