A FAIR marijuana test has never been possible. Until now.

Drug tests that analyze oral fluid, hair, blood, and urine can only tell whether someone used marijuana at some point in the past – hours, days, weeks, or months ago – long after the workday has ended.

The key to a fairer test is the ability to measure very recent marijuana use within several hours of smoking that may impact performance during the workday. That’s why the HOUND® CANNABIS BREATHALYZER is a fairer test – it only measures very recent cannabis use.


Hound Labs detects COVID-19 in breath using ultra-sensitive technology

Hound Labs modified the HOUND® CANNABIS BREATHALYZER to detect the SARS-CoV-2. In May 2020, the company confirmed that aerosolized particles containing the SARS-CoV-2 virus can be measured in breath – even when subjects are asymptomatic. The ability to detect the SARS-CoV-2 virus in breath may help to unravel some of the mysteries surrounding super spreader events.

The future of drug testing

Pre-access testing that can identify the recent use of marijuana prior to entering the workplace is poised to replace pre-employment testing as a preferred method to help keep jobsites safe.

Jenny Lynn, Co-Founder, and Nina French, President at Hound Labs, co-authored an article recently published by the Drug and Alcohol Testing Industry Association (DATIA).


A positive marijuana drug test: What does it mean?

It depends. Different tests detect marijuana use over different time frames. A positive breath test indicates very recent use – within hours of the test. A positive oral fluid test may indicate use days earlier, which may have occurred on the weekend prior to testing. Employers want to keep their employees, so using the right test may prevent an employer from losing a valuable employee.
