The HOUND® MARIJUANA BREATHALYZER, the first ultra-sensitive and portable marijuana test, helps employers balance Safety + Fairness™ in the era of marijuana legalization. Test results from the HOUND BREATHALYZER indicate very recent marijuana use within two to three hours of smoking. Current marijuana tests (using hair, blood, urine, or oral fluid) can result in positive tests for days or weeks after use—well outside the window of peak impairment. Relying on these tests means employers may lose responsible employees who legally used over the weekend, but later test positive at work. The HOUND BREATHALYZER helps employers keep valuable employees while maintaining safety.
