Saliva testing is the best method for detecting recent marijuana use because it is fast, easy to use, accurate, and non-invasive. It provides reliable results that act as an effective deterrent to workplace cannabis use. The detection time for saliva-based testing more closely aligns with the 10-hour potential impairment window for cannabis. Depending on the THC cut-off level, it can detect recent use within the past 12 hours or less.
As marijuana legalization becomes more widespread, saliva testing is a fair, practical, and effective solution for organizations that need to detect recent marijuana use among their employees and for law enforcement purposes.
