Tag: Drug testing limitations

According to a 2024 survey, 82.4% of drug testing providers believe employees are actively working to bypass tests, often using sophisticated methods or substances designed to evade detection. This raises a crucial question for employers and individuals alike: What drugs can't be detected on a drug test, and why do standard screening methods have limitations?

According to research, most routine urine drug tests fail to detect many illicit and prescribed substances, including LSD, ketamine, and certain synthetic opioids. This phenomenon, and the reasons behind it, are crucial to understanding the limitations of common drug screening methods and identifying what drugs don't show up on a urine test.
